We were all tired when we got back to the house. By that I mean that Rachel, Mike and I were tired. Andrew and Kyle were buzzing with excitement. They’d only received Mike’s pictures from the swimsuit shop as far as I knew. My first thought was to insist that nothing else out of the ordinary happened, but then they saw Rachel, who was clearly still covered in Mike’s cum.
“Whoa, what happened?!,” Kyle said, his eyes bulging out at Rachel’s chest. Her crop top was more opaque than in the open sunlight of the beach, but still thin enough that they could easily make out her unsupported breasts and dark nipples underneath. Also, it stuck to her breasts in a pattern that any guy would recognize as cum splatter. Andrew echoed Kyle’s call for the full story, his eyes equally locked on Rachel’s near-naked body.
“What happened is, I need a shower,” Rachel said, strutting past them. She knew the four of us would watch her every step as she left and she put an extra sway in her hips for us. The bottom half of her bubble butt still hung out of the back of her bikini bottoms and her swinging buttocks hypnotized us.
“That was cum, right?” Kyle asked. “On her tits?” Mike turned to me, giving me the opportunity to answer. I struggled to find the words for a moment, then gave up. I didn’t want to tell them about how Rachel had stripped naked and jerked Mike off onto her chest in the middle of a public beach. I was still trying to focus on how much we had both cum when I fucked her right after.
“Mike can tell you, I need a shower too,” I said, following Rachel to our room. I heard their excited murmurs as I left. That familiar pang of humiliation and arousal hit me as I realized they were talking about sexual acts my girlfriend had perpetrated on them. However, I was still too exhausted from the day’s events for my dick to do anything but flaccidly wag in response.
I caught up on emails while Rachel took her shower. To my surprise, none of the guys tried to hop in with her. I guess Mike just had too much to catch them up on. He and Rachel probably only told me the abridged version of whatever happened in the dressing room, and Kyle and Andrew would get the full story. I burned, knowing that they’d know more about my girlfriend’s slutty behavior than I did.
Rachel returned from the shower wearing just a towel around her waist. I wasn’t sure if she was hoping the guys would be in the hallway to see her naked chest again, or if they had seen it so often she just no longer cared to cover it. Either way, I couldn’t think about it for long because the sight of her bare breasts, glowing from the shower and jiggling with every step, erased all other thoughts from my mind. God, they were beautiful. I looked up to her smiling face. She was beautiful. And I was so goddamn lucky to have her. The other guys may see her amazing body (and cover it with their cum, I tried not to remind myself), but I was the one she went to bed with. They’d never know just how good her pussy felt.
“Definitely want to keep things quiet tonight,” she said. “Need to. My body can’t handle anymore.”
“Me too,” I said, relieved. “Spending all day in the sun always wipes me out.”
“Yeah,” she said. “Plus, I feel like my brain and body has been in high tension since we got here. I mean, all the sexy games are fun, but it really drains ya.”
I nodded in agreement. Apart from the physical and mental fatigue, I wanted some indication that we could survive an evening around my friends without her indulging their sexual whims. She took off her towel and I admired her soft, round butt. If I wasn’t so tired, and she hadn’t just said she was really not in the mood, I would have thrown her on the bed right then. But now was not the time.
“Ugh, I really don’t wanna wear panties,” she groaned. “I’ve had things wedged up my butt all week and I just wanna relax.”
“I didn’t know they were such a burden,” I said.
“You don’t know what they’re like. All your underwear is loose and comfy.”
“Not all of it, my boxer briefs are tight.”
“You guys don’t understand. Most times I wear sexy undies, no one sees them but me. They’re scratchy, they’re tight, they get shoved up my bum, and I do it all just in case some lucky guy wants a peek.”
She’d turned back to face me and I had a hard time forming words in such proximity to her incredible naked body.
“I’ll make a deal with you,” she said. “If you wear a pair of my panties all evening and don’t complain once, I’ll never complain about wearing them again.”
“Uh huh,” I said. “And if I do complain?”
“If I win the bet, then you have to wear them all day tomorrow,” she said. I just laughed. She sure was funny sometimes. I slipped out of the room and headed to the shower while she got dressed.
She was gone by the time I returned. A pair of her panties and a note were waiting on the bed, though. The note said, “I think you’d look really cute in these.” I unfolded the panties and looked at them. They weren’t too bad, considering. Her wide hips and thick thighs meant that they’d actually fit me without being too tight. I thought the whole thing was a joke and I hadn’t planned on carrying through with it at all, but now that I held them in my hand, I thought I had an easy win on my hands. They weren’t that different than tighty-whities, and I’d worn those my whole childhood.
I pulled them on and looked at myself in the mirror. They were mostly opaque black lace, and clearly not cut with a penis and balls in mind. Mine wouldn’t stay in the front no matter how I arranged them. I turned around and saw the bottom part of my buttcheeks hanging out. The back did ride up between my cheeks some, but it wasn’t too bad. I threw on a t-shirt and gym shorts and headed downstairs.
I found Rachel, Kyle and Andrew in the kitchen. Rachel and Kyle stood next to the table where Andrew sat, rolling a joint. Rachel had put on a pair of small cotton shorts she wore for lounging around and an old sports bra with a zipper down the front. I was glad she was fully covered, but she hadn’t fully given up the tease. Her shorts were folded over a few times at the waist, pulling them higher up so that her entire thick thighs and the bottom crease of her cheeks were exposed and the middle was wedged up between her cheeks. The bra also showed a fair amount of cleavage, especially since the zipper was halfway down. Both were also quite thin, so we could all tell she wasn’t wearing panties and that her nipples were currently pretty hard (though that could be because of the heavy A/C pumping).
They told me that Mike went to pass out in his room and that they just wanted to smoke some weed and watch a movie. That sounded like a great idea to me. Andrew finished rolling the joint and we went into the living room. Along the way, Rachel peeled back the side of my shorts and saw me wearing her panties. She smiled and gave me a kiss on the cheek. Andrew and Kyle quickly sat down on either side of the couch. That left the two comfy chairs to the side of the couch, so I quickly sat down in the one closer to the couch. Rachel stood in front of us for a moment, pondering.
“What’s wrong?” I asked. “Do you want to sit so we can get started?”
