My Step-Brother's Boyfriend

After college, Mark and I moved in together. Mark has been my step-brother since we were young and we'd always been close. Very close. 

I was in my room, folding laundry with the door open, when Mark came and leaned against the doorframe, silently watching me. 

"What's up, bro?" I ask, glancing back as I continue to work. 

"You doing anything later?" He asks, blatantly looking me up and down.

I smirked and finished the shirt I was folding then turned to face him. "I got no plans, just more of this. Why? What's up?"

"You know that skinny guy I've been fuckin around with?"

"Yeah? Uh.. Tyler?" 

"He goes by Ty, but yeah, him. He's uh.. coming over later."

"Ah, gotcha. Need me to stay inside here for a while?" I ask, returning to my laundry. I started to fold a pair of shorts. 

"Actually, the opposite." Mark says. I pause and look back at him again. He was smirking, arms across his chest. He was a tall guy with short cut brown hair and tattoos along his arms. He was lean and between his legs was a long cock. And right now, that cock was bulging Mark's gym shorts in a way I'd seen a lot. He was semi hard. 

I raised a brow and Mark continued. 

"He mentioned that he wants to fuck with you." 

"And you wanna have a threeway today?" I was starting to get hard too, my sweatpants hiding nothing as my bulge twitched, hidden from my step brothers view. 

"Yes, but that's not all." I raised my brow, finished folding, and turned to face him. Mark dropped a hand to his crotch to grope himself as he spoke. "He wants to be blindfolded today." He says. 

My cock hardened and tented my shorts. We both glanced at it before I dropped a hand to grope myself, like Mark was doing. "So you want me to sneak in and fuck him?" 

"Bingo." Mark said. "He'll be here in an hour or so. I'm gonna shower. Don't you dare nut before he gets here." He says, smirking and looking at my bulge again, before turning and leaving. 

I finished my laundry then went and took my own shower. When I finished, I went back to my room and waited. I was on my phone when I heard the front door open and close. Then a few moments heard the muffled sounds of oral sex from down the hall. I chuckled and started to touch myself, bulging my towel but keeping it on, listening to the sounds of their slowly intensifying hook up. 

After a pause, then music began to play. Then, there was a higher moan followed the unmistakable sounds of sex slowly beginning. And when I heard a whimpered "fuck me" I knew that was my cue. Walking down the hall was a deeply erotic moment as the sounds of music and sex only got louder as I reached the open door of my step brothers room. 

Mark was facing away from me, his back and ass on display as he fucked the smaller man bent over the bed. I left my towel in the hall and stepped inside. Marks hips were slapping against Ty's ass cheeks. I got closer, neither male noticing me as I stroked my hard cock. Soon enough I was could enough to place a hand on Mark's ass. His head turned back, a big smirk on his face. He looked me up and down before his eyes lingered on my cock. Without missing a thrust he dropped a hand to grasp my meat, stroking it long and firm just like his fucking. I inhaled and smirked, throbbing hard and starting to leak already from the sheer eroticism of it all. 

"You like this dick, baby?" Mark suddenly asked, looking into my eyes but speaking to Ty. 

I nodded as Ty moaned out. "Fuck yeah." Mark winked at me, then pulled out. He cockslapped the blindfolded boys hole, looking at me. 

"You want more, baby?" Mark asks, suddenly stepping aside. 

I stepped into place and cockslapped Ty's hole, just as the boy responded. "Give me that dick!"

I pushed my cockhead against Ty's hole, finding it stretched and lubed, my meat easily sliding in and sinking deep inside. My eyes and head rolled back as I wasted no time starting to fuck and hump. 

"Fuuuuck yeah, baby." Mark said, his voice coming from right next to my head. His hand landed on my ass cheek, kneading it as I fucked. "Beg for this dick, baby." 

"I want your dick. I want it so badly. Fuuuuck yes!" Ty's moans rang out over the music. His hands gripped his hips and I fucked hard and fast, breathing hard but keep quiet. I looked from the bent over boys body back to Mark. His gaze was glued to my ass as I fucked Ty. He was idly stroking himself with his other hand, but I reached over and knocked his hand away, grasping his cock and stroking it fast. 

I fucked and stroked, panting and tensing as the moans of his two partners swirled around him. His free hand spanked Ty's ass before spreading it wide. His hips followed and slapped against the skinny boy, as he moaned out for more. 

Mark stepped closer, his cock pulsing against my thigh as I stroked it while his hands kneaded my ass cheek and reached around to grope my pecs. I had to bite my lip to stop from moaning out, my eyes rolling back again. When I focused again, looking back at Mark. Our faces were close as I panted and he smirked. Our lips nearly touched, before he pulled back and winked. He glanced down to Tys ass then back to my face. I read his expression. 

"Beg for my cock, baby." Mark said, as I pulled out, cockslapped Ty's hole, and stepped aside. Mark and I released each other as he stepped in place and slid back into the blindfolded male's ass. They both moaned out as he started to fuck. His hips rolled, his big ass shaking and his muscles tensing. I admired his body for a long moment as Ty moaned out. Then I looked to Mark's face, seeing his gaze glue to my cock. I looked down at it, seeing the hard meat pulsing rigid and swollen, shiny with lube and precum. My gaze moved back to Mark's face, where he was still staring and practically drooling. 

As I stepped forward into Mark's grasp, he stroked and pumped my cock as he humped, his gaze switching between me and Ty. I stepped close, as he had. My hands found his ass cheek and his chests, kneading both and watching as the two fucked in front of me. 

To tease him further, I slid my hand between Mark's crack, brushing along his hole and finding it slick. I raised a brow as Mark looked to me. He smirked again, eyes glazed with lust. Stepping behind Mark I spread his cheeks and pressed my crotch against his crack. He ground back on me as he fucked forward and soon I was grinding my cockhead up and down that crack before lingering on his hole. And as Mark pulled out of Ty, he sank back onto my cock. 

I had to cover my mouth to muffle my moans, but it probably wouldn't have mattered as Mark's loud moans filled the air. "Fuuck. Fuck your. Your ass is so big." He says, keeping up the lie as he looked back at me. A moment later he was back to fucking, humping between me and Ty and moaning loud. My hands slid around, groping Mark's chest as I kissed and panted against his neck. 

"I want your load~" Ty whimpered, gripping the sheets hard as he was pounded. 

"Fuck yeah. Im gonna give it to you." Mark turned his body, wrapping one arm around him as he humped. We looked at each other as he continued. "You gonna cum for me, baby?" 

I nodded as Ty moaned out. "Fuck yeah!" 

Mark was tensing and his eyes rolled back, his hole clenching on my cock and his cock surely throbbing inside Ty's hole. "Fuck yeah. I'm gonna cum, baby. I'm gonna fuckin cum. Fuck. I'm cumming. Fuck. Fuck!" 

Mark's moans filled the air as he slammed in deep and started to cum. His hole clenched on my cock and without missing a beat I started to fuck my step brothers hole. I heard his moans intensify and a moment later Ty's moans loud and high. It then didn't take long for me to thrust deep into Mark's hole and cum hard, shooting my seed inside him while biting his neck silence myself. 

Thankfully Mark moaned out enough for both of us. And as I pulled out, he groaned and gave Ty and few more hard thrusts. I groped his ass and bent down to kiss his cheeks, before I stood and returned to hallway. I grabbed my towel, looking back to meet Mark's eyes. He wink and gave a thumbs up, which I returned before vanishing back to my room. 

It was about half an hour later when Ty left and Mark came to my room. He had put on a robe and found me still in my towel. "That was hot." I said. 

Mark laughed. "It was incredible, man. We've gotta do it again sometime."

"I take it Ty enjoyed the blindfold."

"He loved it and didn't notice a thing." He adds, winking. 

"Good." I said, looking him up and and and smirking. "Now, come here and clean up this mess you made." As I spoke, I opened my towel, letting it open and exposing my nudity. I grabbed my cock, it was coated in half dry cum and was started to harden again. Mark licked his lips and came closer.
