On a swingers resort vacation, Shelly and Dick take week-long gender-swap pills.
Shelly and Dick were on their vacation. Shelly had given Dick his last blow job, at least for a few days. They had taken the pink and blue enhanced pills—the ones that would last for seven days.
I should mention the names they had agreed on. Shelly would now be Sam, and Dick would now be Riki. This name change for Dick and Shelly is for the 7-day X-change pill.
After the first night, the remaining days of vacation went for Riki and Sam.
Riki didn’t know that Sam had contacted the couple they met on their honeymoon, Bob and Carol. The three of them had arranged for the group of swingers to vacation at the same time. Their plans for me would become obvious day by day.
That first morning, Sam and I had some wild sex, oral first, then fucking. He enjoyed the cock sucking; I enjoyed the finger-fuck and him nibbling on my clit, then the vaginal penetration. It just felt so good to be fucked again. Feeling Sam inside me was like heaven.
He woke already hard, that thick 8-inch cock standing against his belly. I slid down and took him in my mouth while he was still half asleep. The taste of him was stronger now, saltier, muskier. I worked my tongue under the ridge and sucked until his hips started lifting off the bed. He pulled me up, pushed my thighs apart, and buried his face between them. Two thick fingers opened me while his tongue circled my clit, slow then fast, until I was dripping down his chin. When he finally pushed that fat cock into my cunt, I felt every inch stretch me open. He fucked me deep and slow at first, grinding against something inside that made my whole body shake, then harder, slapping wet against me until I came with my nails in his back and his name in my mouth.
At lunch, guess who we bumped into, yup, Bob and Carol. Of course, we had to explain to them who we were and why we looked the way we did. They wanted to know why we were doing this and what it was like to change genders. Yes, they wanted to get together that evening. We planned dinner with them.
With lunch over, Sam and I headed to the beach, the nudist section. Sam wanted to expose my body to everyone. I swear he was hard almost the entire time we sat on the beach. The guys were staring and flirting with me; the gals were flirting with Sam.
I must admit it was exciting to be naked and exposed like this. Sam had insisted that I shave my pubic hair smooth so my pussy was bare for all to see. Since he insisted I do it, I did the same with him. It made his cock look even bigger. I loved the look. Every time I shifted on the towel, I felt air on my open lips. Men walking past slowed down. I could see their cocks thickening. Sam’s hand stayed on my inner thigh, fingers occasionally brushing my slit just enough to keep me wet.
For dinner, Sam did my makeup. I dressed in a low-cut, tight dress that exposed my breasts all the way to just above my nipples and tightly framed my bottom. Sam wore a pair of very tight dress shorts that framed his cock in a pouch, very sexy. Bob and Carol had dressed similarly.
After dinner and a few cocktails, the four of us retired to our suite. Carol and I served more drinks. She had all sorts of questions: how did I feel, what was sex like, did I enjoy it? When we brought the drinks out, I sat with Bob, and Carol sat with Sam. Neither man wasted any time grabbing and kissing, feeling us up.
Bob soon had me on his lap. We were making out like teenagers. I could feel Bob’s hard-on pushing right up against my pussy, the heat of it through the thin fabric. As horny as it was making me, I just slipped to my knees, spread Bob’s legs, and undid his belt. He raised, and I pulled his shorts and his thong, yes, a skimpy thong, off.
His cock sprang straight up. It was beautiful, so hard and thick, with a drop of clear liquid on the tip. I think he was as excited as I was. I took him straight into my mouth, tasting that salty fluid. I sucked on the tip of his cock, hoping for more, running my tongue all over, up and down his shaft, cupping his balls, then down to lavish his balls with my mouth, sucking each one, then back up that beautiful hard shaft. I wanted him to explode in my mouth, but Bob had other ideas.
He pulled me off, laid me down, and crawled between my legs. Bob ate my pussy like a man possessed. He spread me open with his thumbs and licked from my hole to my clit in long, wet strokes, then sucked the little nub until my hips were rolling against his face. He brought me to orgasm in record time. I was squirming, moaning, then screaming his name. Bob ate my cunt until I pushed him off and away.
That only excited him more. He rose, grabbed his cock, pointed it at my pussy, and jammed it in. Thank God I was flowing like juice from a faucet. His cock went deep. He pounded me into two quick orgasms, each one making my pussy squeeze him tighter. Bob did not stop. He kept fucking me until his face scrunched up. He looked like he was in pain, then a loud “Oh fuck me!” He orgasmed. His cock expanded and pulsed and pulsed. The heat from his cum caused another orgasm for me.
Exhausted, Bob just lay on me. His weight was almost suffocating. Finally he caught his breath and rolled off me. We cuddled and watched Sam fucking Carol. Carol had control of her cunt muscles like no other woman I had ever had sex with as a man. She was milking him, squeezing and releasing, until Sam’s rhythm broke and he drove in deep, groaning as he filled her.
They both finally came to an explosive orgasm. We watched Sam pump load after load of cum into Carol. When they caught their breath from that marathon fuck, Carol eyed me, smiled, then crawled over to me. She climbed on top and said, “Riki, eat me. Taste your husband’s cum and my cunt together.”
Sam’s cum was literally leaking out, some dripping on my face before I latched onto her cunt. I licked her pussy; there was no cum remaining inside her, I swallowed it all, mixed with her own slick. She then rolled us over and did the same to me. I orgasmed from her tongue lashing, which I’m sure pushed whatever was inside me out onto her tongue.
After that we sat around naked, drank, chatted, then finished the evening with a masturbation session, Bob and Riki opposite each other, Sam and Carol opposite each other. It was really hot watching the men’s faces when they squirted their cum, thick ropes landing on their own stomachs while we women rubbed ourselves to another finish.
The next day, Bob introduced us to a couple that they were friends with, Gloria and Jack. We all hung out at the beach together, naked, of course, drinking, eating, and chatting. Yes, we watched all the naked bodies too, commenting on them. Some of the biggest cocks were on the smallest men. Around mid-afternoon we split up. Sam and I went back to our suite to rest, have intimate sex, eat a snack, then get ready for dinner.
He fucked me slow in the shower, one of my legs hooked over his arm, water running down between us, his thick cock sliding in and out of my cunt until I came with my forehead against the tile.
We met all three couples for dinner. The six of us were having a great time when Gloria asked if it was time. “Time for what?” I asked. She responded, “The airtight party.” I asked, “What’s that?” They said to wait and see. Riki finished her drink, and we all retired to Gloria and Jack’s suite.
We were all sitting around, naked of course, drinks in hand, when Jack brought out a deck of cards. He had us women draw a card and told us the order goes by the highest card first, then the next highest, and so on. The men did the same thing, except for them, the high card gets ass first, second high gets pussy, and next gets mouth.
Now I understood what was coming. The woman with the high card goes first. She gets fucked by all three men at once, ass, pussy, and mouth. Once the first woman has orgasmed and the men have filled her with cum, there is a 45-minute recharge period, then the next round starts.
The first round was Gloria. When the men were in position, the penetration began. First her pussy was entered, then her ass, and finally her mouth. The men didn’t last long, as they all were really horny. Bob orgasmed first in her pussy, then Jack in her bottom, finally Sam filled her throat with jizz. Riki was still cleaning her up ten minutes later, licking the mixture of three loads from her open holes while Gloria trembled.
Next up was Riki. She had never taken three cocks at once. The idea of being opened in both holes while something thick filled her throat made her stomach flutter. Could she stretch enough for Jack’s fat cock in her cunt and Sam’s equally thick one in her ass at the same time? Bob’s already waited, hard and glistening.
Jack didn’t ease in. He gripped her hips, lined up, and pushed hard. The blunt head forced her open; the stretch burned for a second before her wetness smoothed the way. He sank deep in one steady thrust until his pelvis met hers. The pressure filled her, thick, heavy, insistent. Before she could fully adjust, Sam’s hands spread her cheeks. His cock, slick and hot, pressed against her hole. He pushed slower, almost tender, but the pressure still made her gasp. The ring of muscle gave way with a soft, wet pop. Both of them inside her at once felt impossible, two thick shafts sliding against each other through the thin wall that separated cunt and ass. Every small movement of one was felt by the other.
The light scream that escaped her gave Bob exactly what he needed. He caught her jaw, tilted her head, and drove straight into her throat. The sudden fullness cut off air and sound. Salty, musky cock filled her mouth and kept going until her nose pressed against his belly. She gagged once, hard, eyes watering, then forced herself to breathe through her nose as he began a slow, deliberate rhythm.
Jack set a punishing pace right away, short, hard strokes that slapped wetly against her and made her whole body rock. Each thrust shoved her forward onto Bob’s cock and back onto Sam’s. Sam moved opposite him, slower but deep, grinding so the two shafts rubbed constantly through that thin membrane. The dual friction was overwhelming: pressure, stretch, heat, the slick slide of skin on skin. She could feel every ridge, every vein, every pulse. Her clit throbbed untouched. Her ass burned sweetly around Sam’s girth. Her throat worked around Bob’s length, tasting him, smelling the sharp male scent of his skin and the cum already leaking from the other two.
The men lasted far longer this round. They were still hard and driving when the orgasm hit her like a wave she couldn’t stop. It started deep in her cunt, clamping hard around Jack, then rolled through her ass and up her spine until her whole body went rigid. She couldn’t scream. Only wet, broken gurgling sounds escaped around Bob’s cock as her throat convulsed. Her back arched hard. If the three of them hadn’t been holding her in place, she would have collapsed. The rhythmic spasms of her cunt milked Jack mercilessly. He cursed, slammed deep one last time, and flooded her. Hot pulses of cum filled her until it had nowhere to go and began to leak around his shaft.
The same contractions locked around Bob’s cock in her throat. He groaned low and long as he unloaded straight into her stomach, thick, salty jets that she had no choice but to swallow. Jack’s cock softened and slipped free almost immediately, leaving her cunt open and dripping. That sudden emptiness gave Sam more room. He took it, fucking her ass harder now, using the extra space, chasing his own finish. Five more minutes of deep, grinding strokes while she still shook from the first orgasm, then he buried himself to the root and unloaded. She felt every heavy pulse of cum shooting deep into her colon, hot and thick, until it was more than she could hold.
When he finally pulled out, the mixture of their loads, Jack’s from her cunt, Sam’s from her ass, ran down her thighs in warm, sticky rivulets. Carol moved in without a word and began the clean-up, tongue working carefully through the mess while Riki lay trembling, still trying to remember how to breathe.
The third airtight of the night was Carol. When the guys finished fucking Riki, they were worn out. It took them a good hour and a half to get hard again. Although not as hard as previously, they were sufficiently hard enough to fuck. Carol got the longest fuck. She orgasmed four times. The only man that deposited much cum was Sam. The other two didn’t have any sperm left to give. Gloria had clean-up duty, which brought another orgasm to Carol.
After three rounds of airtight, everyone was exhausted. No one was interested in drinking or chatting. They all gathered their clothes and went back to their respective suites.
The next morning, Riki woke up sore. Her pussy felt puffy. When she looked at it, it was red also. Her bottom hurt as if a large pole had rammed her. Her throat was also sore. She looked at Sam, still sleeping, his cock sticking straight up. Knowing the way she felt, there was no morning fuck or blow job for Sam today, a hand job maybe. She wrapped her fingers around him and stroked until he woke with a groan and came across her tits.
Today was a spa day for the ladies. The guys were hanging out, as far as she knew. They did plan to have dinner together.
At dinner that night, they talked about the previous night, what they enjoyed or didn’t like, and what was planned for tonight. We decided to check out the lounge for a drink. That’s where we met Joe. He was sitting alone. His husband was not feeling well, so he stayed in their suite.
The men asked Joe to join us. As the drinks flowed, the men started talking about their carnal plans for tonight. Sam suggested a men-only night, you know, male bonding, that kind of stuff.
Gloria suggested that we women go to her suite and the men go with Sam to ours. It was late, 1 a.m., before I got back to the room, only to find the men engaged in homosexual activities. What I saw when I walked in was Sam fucking Joe and Jack fucking Bob. They didn’t hear me come in, so I watched until Sam orgasmed in Joe’s ass with a mighty roar, hips locked, cock pulsing as he pumped him full.
When Sam turned around to grab a towel, he saw me and announced to the others, “We have an audience.” Sam and Joe came and sat next to me as we watched Jack pound Bob’s ass. Jack’s orgasm in Bob’s ass sounded epic. Jack screamed, “Oh fuck, take my cum you slut!” Bob’s cum was on the floor where he had squirted minutes before.
With all the gay sex over with, the guys and I talked about the evening and what comes next. For Sam and me, it was sleep. We only had one more day and night before we changed back to our birth gender. Once in bed, I sucked Sam’s cock. He didn’t cum, but I enjoyed the weight of it on my tongue, the way it filled my mouth, the taste of Joe still on him.
The next morning, Sam fucked me, leaving a huge load of cum dripping out of me. After breakfast, we headed to the nudist beach to meet our friends. A surprise was that the gay couple were there also. Bob had invited them, and also invited them to our sexual gathering tonight.
All the guys were naked, I must say! Joe’s husband had the biggest dick of all the men in our group. I would like him to fuck me, to experience what a really big cock felt like. I whispered that to Sam, who whispered back that he would see if he couldn’t make that happen.
His name was Mike. I could see him check me out when he and Sam were talking. I wasn’t sure what Sam told him, but he did wink at me one time. Later that afternoon, Mike was sitting next to me. He started telling me about what Sam had told him, which was basically everything. He also told me he doesn’t generally fuck women, but he would make an exception for me, but he’d only fuck my ass if I were up for that.
That night after dinner we all met in Joe and Mike’s suite. The game tonight for the first round was pick a name out of the bottle. I’m sure it was rigged, as Mike got my name.
It was a little different tonight. Two couples took the California king bed, one couple on the couch, Mike and I on the outside deck on a futon.
For Mike being a confirmed gay man, he was a wonderful lover. His kisses were divine, slow, deep, tasting of rum and heat. I sucked his cock to an orgasm, but he never lost his erection. The size of him stretched my jaw. He didn’t lick my pussy, but he ate my ass as I’ve never had it eaten before. His tongue pushed inside, wet and insistent, until I came from his mouth on my bottom, munching away, my clit throbbing untouched.
When Mike penetrated my asshole, I was so loose and open there was no pain, only some stretching. That massive cock filled me until I felt it in my throat. He fucked me through two anal orgasms. I did rub my clit throughout the fucking. When Mike orgasmed, I was sure the entire hotel could hear him. He bellowed and cursed, screamed my name. The amount of cum he deposited inside my bottom was copious, as it leaked out all night, warm and thick down my thighs. I really, really enjoyed Mike—his lovemaking, his cock, and his butt-fucking me.
We traded partners one more time. This round, I was paired with Joe, yup, the other gay guy. Mike and Sam were together, then Bob and Jack traded wives. I was happy to see Sam was with Mike; that way we could talk about and compare our experience with the big cock.
Joe was a good lover, a good kisser. He also didn’t eat my pussy, but he did fuck my cunt and then my ass, cumming in my ass, so I got cum from both gay men. As a comparison, Mike was a better lover than Joe. But I would take either one again, as a man or woman.
On the walk back to our suite, I noticed Sam was walking a little differently. Once we were in bed, we talked about the sexual events of tonight, what we liked the most. I gave Sam a good-night suck; he rubbed me until I came quietly against his fingers. We kissed for the last time as different genders.
I woke up in the morning happily as Dick, and yes, I had a hard-on. I looked, and yes, my gorgeous Shelly was next to me. I was relieved that we had made another successful transition.
