Mark and the Missing Towel

I didn't hear my stepbrother come home, or sneak into the bathroom. I was too focused on my shower, and my morning wood that I couldn't stop touching. But when I came out of the spray I knew he'd been there. My clothes and towels were gone. 

He'd done this kind of thing a lot when we'd been younger, and later admitted he did it to see me naked. And so, I figured I would give him what he wants. 

After letting myself drip dry for a painfully long moment, I left the bathroom, naked and damp. The hall was empty but the door to Mark's room was open. I stepped into the doorframe and leaned against it, looking at my stepbrother laying in bed on his front, shirtless but still in a pair of gym shorts. My towel was wrapped around his neck. He looked up from his tablet and smirked at me, eyes blatantly scanning my body up and down. 

"Well good morning to me." He said with a lewd smirk, eyes lingering on my semi hard manhood. 

I rolled my eyes. "If you want to see me naked you can just ask." 

"But this is much more fun." He says, putting his tablet on the side table and standing up. I couldn't help but notice the sizable bulge in his thin shorts. "And besides…" He tossed the towel at me. "You look better naked." 

I rolled my eyes again and started to dry my face. Then, in my moment of blindness, I felt him swallow my cock. 

"Oh." I said. Not truly surprised but unable to deny my pleasures either. His mouth was very skilled. I moved the towel and looked down, meeting his gaze as he grabbed my cockbase and bobbed his lips along the rest of my shaft. His hand slid down to my balls as he plunged his lips down to my cockbase. "Ah, fuck yeah." 

He gagged and coughed before pulling off, a hand quickly grabbing my saliva slick cock and stroking it quickly. I growled softly and placed a hand on his head. He looked up to me again with a smile and began to lap at my cockhead. I bit my lip as his eyes closed and he closed his lips around my cockhead. He sank deeper with each stroke of his lips and was soon throating my cock again and again, making me moan out loudly. 

The towel was forgotten and dropped to the ground, my hand idly resting on Mark's head as he blew me. And when he came off my cock with a deep gasp for air, he again stroked me immediately. My hand left his head as he went down to lick and suck my balls, making me groan lowly. After a long moment, he swallowed my cock again, then pulled off and stroked me, while looking up, eyes glazed with lust. He soon stood up, his shorts remaining on the ground. 

I licked my lips as I looked him up and down. He smiled at me, stroking his own hard cock. He gestured with his head back into the bedroom and I followed. And when he sat down on the edge of the bed, I knelt between his legs and started to suck his cock. 

I licked the underside of his shaft, getting to the top and sucking it into my mouth. Mark leaned back on an elbow, watching and biting his lip. Eventually he laid back fully, his hand rubbing my shoulder for a bit before rubbing my head as I nursed his tip in my lips.  

"Feel good?" I asked, licking up his shaft again then giving the tip a dozen hard swallows. I looked up at him as I sucked on his tip. 

Mark sat up again. "Fuck yeah." My hands were on his balls and his cockbase, fondling and holding them as I sucked and bobbed harder and faster. "Ah, yeah." He groaned, rolling his hips gently against my lips. 

Soon, he was thrusting,  and standing. 

My hands fell away from his body and his hands found my head and his own cockbase. He humped my lips and soon fucked my face, heavy balls slapping my chin. I gagged low but never pulled away as Mark groaned his pleasures. And soon enough he released his own cock and grabbed my head with both hands, fucking my throat. When he finally pulled off and let me gasp and pant, his cock and my lips were a mess of saliva, strands connecting the two. 

I wiped my mouth and smirked up at him. Mark was smirking back at me. Wordlessly, he turned around, knelt on the bed and spread his legs wide, his muscle butt spreading for me. I bit my lip and the sight, admiring it for a moment before moving closer, still on my knees. 

I spanked both his cheeks firmly then groped and spread them wide, just as I leaned in and began to kiss and lick his eager hole. Mark let out a hot gasp then a low groan, before panting and pushing his face into the sheets. I pulled back and spat on his hole then began to tease my tongue inside his rim. 

I pulled back again, this time leaning low and licking from the base of his balls up his crack and past his hole. He shuddered so I did it again. After the fourth time I went down licked from his cockhead up to his base, over his balls and up his crack. This time he moaned out. 

"Ready for my cock?" I asked after a few more minutes of teasing his crotch and crack. 

Mark rose from the sheets and looked back at me, flushed in the cheeks. "Fuck yeah, bro."

The sight of him bent over, spread and loose, and looking back to ask for it made me bite my lip. I stood up, stepped close, and cockslapped his hole. 

When I pushed against Mark's hole, he relaxed and took me eagerly. He still moaned out, his face back in the sheets. I sank in, just my cock head and the first inches of my shaft. I rocked slowly, getting his hole to relax as he adjusted to my size. And as I felt him opening up for me, I sank deeper inside. 

By the time I was balls deep, Mark was whining into the sheets. I was smirking, holding his hips firmly as I held myself deep, feeling his rim clenching on my cock base. But once again I waited for him to open up for me. And as he did, I started to fuck. 

First I rocked long and slow, groaning as I pumped through his hole. And as I gained speed, Mark gained confidence. "Fuck yeah." He panted, raising his face slightly off the bed. "Yeah, fuck me." I started to thrust harder and faster, my heavy balls slapping against the other's equally heavy pair, the sound filling the air along with our combined moans and the lewd sound of my cock pumping his hole. 

I gave his cheeks sharp spanks, making him whine again, but soon he was on his hands looking back and arching his back. "You like this cock?" I asked, biting my lip and looking at his face. He nodded and I slammed in deep, holding and grinding there as he moaned and rolled his head back. "Say it…" I muttered, holding still. 

"I love your cock in me." He said, biting his lip now as he looked back. "I love when it's fucking me hard and deep." 

I rewarded him with just that, fucking him hard and deep. I was grunting and moaning as I pounded him, my cock hard as steel and leaking copiously, making his hole even more slick. 

Then, I heard what I wanted to hear. Mark looked back, his head and body rocking with my thrusts. "You wanna get fucked?" 

I spanked him hard and gave a quick flurry of thrusts, before pulling out fully and cockslapping his hole. "I would love your cock fucking me hard and deep." I mused with a wink. Mark bit his lip again. 

A moment later I was on my back in the spot where Mark had been. He was between my legs, kissing and licking my balls. He grabbed the back of my knees and lifted them high, his tongue finding my hole a moment later. 

"Fuck…" I gasped, my voice breathy. He grabbed my cock and began to stroke it while slowly licking my hole. "Ah, fuck yeah…"

"That feel good?" He asked before pushing his tongue inside of me and beginning to rim me. 

"Fuck~!" I gasped again, tensing and gripping the sheets. "Fuck yeah. It feels great! Fuuuuuck." 

Mark came away from my ass, licking up my balls and cockshaft, suddenly sucking and swallowing my cock deep. I moaned again only for him to pull off and go back to my ass. 

He did this a few times. Whenever I adjusted to one form of oral he would switch to the other, leaving me no moment to gather my thoughts as I laid there in pleasure. 

Then at one point, while he was sucking my cock, he sank a finger into my hole. "Mark!" I gasped, eyes going wide then rolling back. My hands gripped the sheets, as I throbbed hard, suddenly feeling an orgasm coming fast. "I'm close…" I panted. But he already knew that as my cock throbbed hard and leaked even more heavily. And he wasn't stopping. 

"Fuck yeah. Fuck I'm gonna cum. Fuck. Fuck!" He kept sucking and finger, until my back arched off the bed and I was flooding his lips with my seed. "Fuck!" I groaned, throwing my head back into the bed as I squirmed through my orgasm. Soon enough, Mark came off my cock with a smirk, licking the tip as it pulsed. He drooled my load back onto my cock, his free hand going to stroke it over my length and making me continue to shudder. Eventually he gave me one long, slow, milking stroke to gather my cum and his saliva back onto his hand. 

-

Mark stood up, stroking himself, still with a finger inside me. I looked down to see him stroking my load over his hardon. I bit my lip and looked up to meet his gaze. "Still wanna get fucked?" He asked, slowly withdrawing his finger. 

When it came out, I inhaled, then grabbed my own knees and spread myself high and wide. "Fuck yeah, bro." I said, a dirty smirk on my face. Mark's face lit up and he moved closer, cockslapping my rim then pushing against it. 

"Yeaaah, fuck." He groaned, his cockhead pushing inside me and making me gasp again. I held myself open as he sank deeper, my gasps turning to whimpers as my eyes rolled back. "Fuck, you take it so good." 

I was flushed. I could feel it. And when Mark grabbed my cock again we both realized I was still hard as a rock. He squeezed it a few times and kept pushing into me. And when he hit balls deep, I gasped and looked up at him with wide eyes. 

"You must really like my cock inside you. You're still so hard." He slapped my cock against his own hard, making me groan low. "Even after I made you cum." He emphasizes the last four words, making me flush. "Hell, even my fingers made you cum. This must be heaven." 

In the back of my mind I heard a challenge. But at that moment I couldn't do more than moan and squirm. He started to fuck, first deep and slow, then spreding up but keeping the depth. I moaned, eyes rolling back or my back arching. Mark's continued stroking of my cock was only another sensation that kept me whimpering. 

He groaned and panted. My hands left my legs and went to feel over his chest and shoulders, then his arms. I only then realized I'd wrapped my legs around his waist. I started to roll my hips, grinding back against the thrusts, moaning out as our bodies slammed together hard. 

He gained depth, pulling back further with each thrust, eventually his entire cock pulling out of me then sinking back in. And as he did this he leaned down and started to kiss me. 

I could've happily stayed like that all day. But, the implied challenge echoed in my mind. And when he broke the kiss and smirked at me, I smirked back. "Wanna get fucked again?" I asked, having reached between us and slapping my rigid meat against his abdomen. 

Mark chuckled. "Fuck yeah." 

He straightened up and sank in deep, pounding me hard and fast for a while before pushing my legs together and to the side, fucking me sideways. All I could do was moan and grasp at the sheets. And when he finally pulled out and gave my ass a sharp spank, it took a moment for me to gather myself. 

It was Mark's turn to be on his back. I stood and he took my place, spreading his legs wide and exposing his slick and stretched hole. I bit my lip and moved in to cockslap it a few times. And as i pushed back inside of him, I reached and grabbed his cock at the base, holding it firmly. 

Mark moaned out, biting his lip and his eyes closing tight for a moment before he looked up to meet my gaze. "You like this cock?" I asked, again. 

"Fuck yeah, bro." Mark said, licking his lips and reaching up to playfully slap my chest, then grope and shake it. I smirked and gave his chest a few playful but firm punches, then, with my fists on his pecs, I leaned forward and pushed in, watching closely to Mark's face as I smoothly filled his hole again.  

"And I love your ass, bro." I rolled and humped my hips, fucking Mark deep and slow. My hands left his chest and went behind his head, holding it firmly as I leaned in to kiss him. And as our lips met, I started to fuck harder and longer. And when Mark finally broke the kiss to moan and pant, I smirked again. "And now that I already came once, I can really fuck you this time." 

Mark's eyes went wide for just a moment as I straightened up. They then rolled back as I started to fuck him fully, my cock pumping long and deep and fast. I was groaning too, but not like Mark, who was squirming, grabbing the sheets as I had, and was leaking precum from his big cock. 

Soon enough, even as Mark moaned and squirmed, I raised one foot onto the bed, then the other, squatting and mounting Mark as I rolled his ass higher. I fucked deeper, balls slapping his ass as my cock plunged inside over and over. 

"Fuck~!" Mark gasped, his tone different. And when I felt his hole clench I knew what was coming; him. 

Mark's hole squeezed me tight as I fucked the cum out of him. His cock swelled and fired off wildly, bouncing around as I hump, spraying his load over his face, neck, and chest along with the sheet around him. 

It wasn't until his cumshot ended and his orgasm slowed that I slid down to my knees, still on the bed and still inside Mark. He sat on my lap as I smirked down at him. "How was that for making you cum?" I asked, emphasizing the last three words. 

Mark blushed then smirked. "It was pretty damn good. But…" He reached down and slapped his cock on my abdomen. He was still as hard as I was. "I'm still going and I think I'm still in the lead." He winked and clenched his hole on my cock. 

"We'll see about that." I shot back, rolling him onto his side, pressing his legs together, and starting to fuck him sideways as he'd done to me. 

-

Mark moaned out. Getting fucked so soon after orgasm would make any man squirm, and here was Mark grasping the sheets and whimpering as I pounded him. I rolled him onto his front, laying over him perpendicularly, and fucking down into him hard and deep. My balls slapped against his ass cheek and he moaned into the sheets as he had before. 

After a while I pulled out and moved Mark back onto his back. I wanted to see his face. I spread his legs and sank back into him and went straight to pounding, his head slamming back into the bed as he moaned out loudly. "Fuck yeah. Fuck yeah." I grunted, the sound lost under Mark's moans. 

My hands slid up his torso, teasing his nipples before going to hold his neck. Mark gasped and whined, my grip tightening as he rode back onto my dick. I watched his eyes go wide while he panted, and when I released him I started to pound again. "Fuuuuuuuck yesssss!" 

I pulled out. We were both panting and our cocks both looked ready to fire off. I gave us both a moment of respite as I leaned down to kiss him again. We made out, his legs wrapping around my waist and his arms around my neck. For a long moment we stayed there, kissing and entwining. And when he finally broke the kiss, he smirked at me. "Wanna get fucked, again?" 

The question had a devious tone. My cock throbbed hard at the idea and I knew I wouldn't last long with him inside me. But, an idea came to mind. 

"Fuck yeah, bro." I answered, lingering on the last word, before straightening up. I grabbed his knees and kept him wide and high, and rolled my hips to sink my cock back fully inside of him. Mark gasped and it was my turn to smirk. "But…" I started. 

My hands slid to Mark's hips, holding him firmly and keeping our bodies together, as 

I rolled back onto my back and pulled Mark onto my lap. "Oh! Fuck!" He gasped out, now fully sitting on my cock as I adjusted so my feet were flat on the bed. I looked up at him, hands still firmly on his hips. 

"But," I continued. "I want you to fuck me with an ass full of my cum." Then, without any further warning, I started to fuck. 

I pounded hard up into him, first letting gravity bounce our bodies together before then holding Mark halfway up my cock and slamming my hips between his hole and the bed. 

"Fuck!" Mark gasped. His head rolled back. I felt his hole clench hard and looked to see his cock twitching and throbbing. This plan was working better than expected for both of us. "Fuck. Fuck. Fuck!" 

I slammed up deep into Mark, holding there and tensing as I started to cum. I bred him deep then continued to thrust with each blast of seed. And as I did, Mark came all over my torso and neck, cock bouncing and firing wildly as I once again made him cum handsfree. 

Our bodies relaxed onto the bed. I grabbed Mark's shoulders and pulled him down into another deep kiss as we came down from our mutual orgasm. And when he finally calmed to normal, I decided to tease my step brother. 

"I'd say we are pretty even now." I muttered against his lips, looking into his eyes. I leaned back, smirking. Mark straightened a bit. My cock inside him had softened slightly but was growing against the bred hole ground on my lap. "And remind me. Both of your loads were fuxked out of you handsfree?"

Mark's glare was a mix of competitive rage and lusty admiration. He looked down and smirked. I looked to see what he was smiling at, just as he slapped his cock on my messy belly. He, like me, softened a little bit, but was stiffening up again. 

"We've still got time to change all that." He answered. He had a playful smirk on his face and he began to roll his hips, riding my cock as we both stiffened. 

"Yeah?" I asked, reaching to grope and spread his cheeks while rolling my hips to meet his riding. Our bodies ground together smoothly, my hard cock hitting deep inside his messy hole, making us both groan. "We'll see about that." 

I gave a firm thrust, then another, starting to fuck and bouncing Mark on my cock. I gained speed and force, grunting as Mark groaned and moaned. And as fun as it was to make him squirm, I was a man of my word. I settled down onto the bed, hands rubbing his inner thighs then going to stroke and grabbed his cock and balls. 

"Now that you've got an ass full of my cum…" 

But Mark cut me off. "Wanna get fucked again?" 

I smirked, slapping his cock on my own belly. "Fuck yeah, bro." 

-

Mark stood up off my cock and we paused for a moment, panting and chuckling, praising each other's skills, and going to drink some water. But before we were back in the room, we were going at it again. 

I was leading the way up the stairs when Mark slapped my ass. I jumped and chuckled and when I reached the top of the stairs I stopped and bent over. I had expected him to be a bit playful then we'd go to bed. But instead, his hard cock slapped my crack and hole. 

"You want my cock?" He asked in a low voice. I looked back. I was kneeling on the top step, ass pressed back as he teased it. I nodded and he smirked, pushing his cockhead into me. "I want to hear you say it."

I opened my lips to answer but moaned out instead as Mark sank inside. After pounding me earlier it was an easy task to slide right back into fucking me. I let out a hot moan as his balls pressed against mine, but teasingly he held there. "I want your cock." I said, but no response. I swallowed. "I want your fat cock fucking me deep and hard!" 

That did it. He grabbed my hip and my shoulder and started to pound, fucking me hard and deep and making me moan out loudly. "Fuck yeah. Take this fat cock." He grunted, moving one foot to a higher step to fuck me faster. 

"Fuck yes! Fuck me! Fuck me!" The words spilled from my lips as my back arched. The hand left my hip and spanked me over and over, turning my moans to whimpers. And when the hand on my shoulder moved to grab and pull my hair, the whimpers turned to whines. "Oh… FUCK!" 

Mark sank deep and held there, his other foot moving to a higher stair as he mounted my ass and fucked me harder. He gripped the handrail, using the leverage to his advantage. And as I had said to him earlier, now that he'd shot a load, or two, he was ready to fuck me for a long time. 

He moved us onto the landing, squatting and mounting my ass, pushing my chest and face into the carpet as he pounded. He pushed me against the wall, sucking and biting my neck. And eventually we were back in bed. I was kneeling on it, legs spread and back arched. Mark was standing off the bed between my legs, just how I had first fucked him. 

It felt fantastic. I was glad I'd also cum twice because otherwise I'd certainly be shooting already. "Reach back and spread your cheeks." He commanded. I did so, moaning as he sank deeper from this. His hands slid to my neck, holding firmly from behind. I swallowed and panted, my body bucking with each hard thrust. And soon enough, he was shoving my face back into the sheets and was joining me on the bed, squatting and mounting me again. 

"Cum in me!" The statement escaped my lips. "Fucking cum in me. Load me up, bro. Breed me like I bred you!" 

That did the trick. Mark tensed and I felt his cock stiffening and swelling. "Fuck yeah. Fuck, I'm gonna cum. Fuck!" Mark fucked harder and harder, my body aching with pleasure as our bodies slapped together. And then, he slammed in deep, and started to cum. And just like I had, he continued to thrust with each blast of seed. 

I chuckled as we kept rocking together through his orgasm, hips slowing as his cumshot slowed. I licked my lips and looked back. "So-" 

But his actions cut me off. He gave me a hard thrust  and I was left to gasp out. Then he started to fuck me again. His hands grabbed my shoulder and pulled me to straighten up, before his arm wrapped around my neck. "That was hot, bro." He growled in my ear. "You're so fucking hot."

He was fuxking hard and deep, grinding along my insides and making me moan. His free hand slid to my front and grabbed my chest then teased my nipple. 

"I wanna make you cum, bro." His words were soft and low in my ear. And they were working. I tensed and he whispered. "Cum for me." 

My load shot out hard, spraying over the bed as I gasped and moaned. And the whole time Mark kept fucking me, pumping the cum from my cock. 

When we both finished and collapsed on the bed, we were chuckling between our heavy breathing. "Let's call it a tie." I suggested. 

Mark stopped laughing. "Are you kidding?" He asked. I raised a brow and he smirked. "I'm game for round 4." I heard the sounds of his semihard cock slapping his own abdomen. I shook my head and chuckled, which turned to a laugh. 

Epilogue

We'd fucked for the entire morning, and a little into the afternoon. After flip fucking again and giving each other a fourth load, we finally agreed to a break. It was our day off, but we still had things to do. Mark went shopping while I did laundry. I showered while he was away and after helping him bring in the groceries, he showered while I folded laundry. And as I heard the water begin to run, I paused and snuck towards the bathroom. 

Mark left the door cracked, as we both always did, so I got close and peeked. Mark stepped into the shower and closed the curtain, vanishing from view. Silently, I crept inside, snatched his clothes and towel, and rushed back to my room. Eventually the shower stopped. And after a long pause, Mark appeared in my doorway. He was naked, hard, and damp. He was smirking as he spoke up. "If you want to see me naked, you just have to ask." 

"But this is much more fun." I said in response, putting down my tablet and walking towards him. I handed him the towel. "And besides, you look much better this way." As he dried his head and face, I sank to my knees and began to suck him. 

"Oh!" Mark said, but finished drying before looking down. Our eyes met and he wore a devious smirk. "Round Five?" He asks, softly. 

I answered by closing my eyes and swallowing his cock to the base.
