My wife and her sister were arguing again, this time about some no-name actor that played in some long-ago watched movie, and whether he was dead or still alive. At 26, my wife Cindi was in her prime and was looking smoking hot that night and Heather, her sister at two years her junior, was almost as attractive. Both were tall and skinny, but Cindi had bigger boobs and brown hair while Heather was blonde with small perky tits. It was a Friday night and we were at the house that Heather and her husband Brian had just bought having dinner together, something that we tried to do once or twice a month.
“I know he’s dead, I remember reading about it in People”, Cindi insisted! She was absolutely certain that she was right and was not going to back down. Knowing my wife, I suspected that she may have been wrong, but I wasn’t going to tell her that. Brian and I were content just watching the exchange, since it involved two very beautiful women.
“Still alive, he just did a part in Law and Order, I remember!” Heather shot back. “I am so confident that I’m right, I’m willing to bet on it.” And she stuck out her hand.
“Name the terms, bitch, I’m in!” Cindi retorted. Brian’s eyes widened, as he prepared to defend his wife, but Heather knew it was just banter and waved him off. I gave my wife a warning glance, knowing her propensity to get into situations like these without really thinking them through. She ignored me. “Make it something big this time.”
Heather gave her husband a sidelong glance and a wink, then slowly smiled. “OK,” she said, “tomorrow we’re going Christmas shopping at the outlets right? The loser’s husband has to be our slave, for the entire day.”
Brian and I both started to protest, as we both had big plans for the next day. I was going to put the Christmas lights on the outside of the house, and he had a big college football game he had wanted to watch. Our wives didn’t seem to hear us.
“Deal!” Cindi said, hardly even thinking about it. “James, look it up.”
I pulled out my phone, and looked up the actor in question in IMDB. My suspicions were confirmed, and with a groan I muttered, “still alive. Law and Order episode last month,” as a cheer went up from across the table. There go my hopes for a quiet peaceful day tomorrow.
My wife did feel a little bad for agreeing to use me as a bet item, so she made it up to me after we got home by letting me come in her mouth. Deep down I wasn’t overly upset about spending the day with these two; they were both hot and I got along pretty well with my sister-in-law.
I awoke at 7 the next morning to the doorbell ringing. Cindi was already in the shower so I threw on a robe (we sleep naked) and went to answer it. It was Heather, looking gorgeous and chipper in a tight white turtleneck and even tighter blue jeans. “Good morning,” I mumbled as I moved aside to let her in.
She came in and looked back at me as I closed the door. “Drop the robe,” she demanded. I started to protest, but she cut me off immediately. “You are my slave, I won the right to boss you around all day. Now lose it.” My cock, which had already been at half-mast from just waking up, immediately jumped to full attention at the thought of being naked in front of my sister-in-law. Shrugging, I removed the robe and let it fall to the floor to a gasp from my visitor. I was fairly well-endowed at 8” and was currently displaying all of it, pointed directly towards her face. She looked like she was in a daze and reaching over she tentatively pushed on my head, letting it bounce up and down a little. The touch sent shivers up my spine. After a moment, she seemed to snap out of her daze. “Well, naked man, how about making us some breakfast?” I reached for my robe but she stopped me, “no, just like that.” I just shrugged and started about making some pancakes and eggs while Heather sat at the kitchen table and chatted with me, hardly taking her eyes off my cock. Cindi came in when the food was about done and stopped short and smiled when she saw me standing at the stove naked with her sister sitting by me. It seemed that they had already discussed some of their plans for today because she didn’t seem entirely surprised that I was naked in front of Heather. Instead, she came up to me and kissed me on the lips, then bent down and took my entire cock in her mouth.
“I’d say I’m sorry about this,” she whispered in my ear after she stood up, “but it doesn’t seem like you’re disliking it much.” I just smiled, my cock betraying me anyway, and she sat down next to her sister while I served them their breakfast.
They ate while I showered and dressed and then we headed out. The day wasn’t too bad, mostly me driving them around, holding their bags, and getting their lunch and snack orders. The shops were crowded and there were always lots of beautiful women to look at, however I was unable to see any more beautiful than the two I was with.
Things started getting interesting after lunch when they dragged me into Victoria’s Secret to get fitted for new bras. I sat down by the dressing rooms while they picked out some items, then they both went into separate rooms to try them on. A few minutes later, Heather opened the door to the dressing room and beckoned me inside. “I need a man’s opinion on this” she said. I couldn’t stop staring – she was wearing a red sheer Christmas outfit and a sexy Santa hat. I could clearly see her hard nipples through the top and it bellowed around a sexy red thong, which was also sheer. I could see her swollen pussy lips through it and they appeared to be moist. I could also tell that she was breathing heavy and knew that she was turned on displaying herself to me like this.
“You’re gorgeous,” I said truthfully, “Brian will love it.” She just smiled conspiratorially and thanked me. She started going through her other things to decide what to try on next, so I started for the door.
“You can stay,” she said tentatively. Hesitating just a second, I sat back down on the little bench, adjusting my raging hardon as I did. She lifted the top off over her head and for the first time I was able to admire her beautiful breasts bare. They were everything I had imagined they would be. She shimmied out of the thong and stood there naked, her shaved pussy on display right in front of my face. She was facing towards me going through a stack of bras she had hanging on a hook over my head, and I didn’t know what came over me. I leaned my head out and ran my tongue across the top of her pussy. She was wet and tasted delicious. She gasped out loud but didn’t step away, she just spread her legs slightly, so I took it as in invitation to continue. I grasped her ass with my hands and pulled her to my mouth, sucking on her clit while I massaged her ass cheeks. I plunged my tongue deep inside her and she squealed out loud. I pulled out my tongue and continued sucking on her clit while I inserted a thumb into her pussy. I reached around and put my index finger into her ass hole and reached up with my other hand and grabbed her right tit. She must’ve been wanting it all day because she came in about 15 seconds. I could tell she was trying to be quiet but her muffled screams had to have been heard in the waiting area, if not throughout the store.
After a minute I snuck out back to the waiting area, and she came out a few minutes later, looking slightly flushed but otherwise put together. She decided to buy the red outfit and a couple of other bras. Cindi came out also and gave me a quizzical look but I just smiled at her and stood up to take her items up to the counter to pay.
On the way home Heather said that she would drive, and Cindi hopped in the back with me. We had been on the road no more than a few minutes when Cindi ordered me to remove my clothes. “All of them!” she demanded. As quickly as I could, I removed all my clothes, leaving me feeling very exposed but incredibly turned on. “Now take off mine as well,” she demanded. I willingly obliged. Once we were both naked, she climbed onto my lap facing me and lowered herself onto my waiting cock. Over her shoulder I saw Heather adjust the rear-view mirror and I knew that she now had a perfect view of my cock going in and out of her sister’s cunt as she was driving down the road. I knew my wife well enough to know that soon enough she was getting close and I wanted to send her out with a bang. While still on my cock, I turned her around so her back was to me and I grabbed her tits from behind pinching her nipples. She was now completely on display through the front windshield if anyone happened to be looking in and I knew that she was enjoying being on display. Heather also had a nice view from the driver’s seat and I knew that she was having a hard time focusing on the road. My wife was screaming by now, yelling out my name and that I had better not stop and because she was coming. I came too, and with a loud groan shot my seed far into my wife’s steaming cunt as she slowly came down from her high. We rode the rest of the way home naked, still trying to catch our breaths.
We got home and got cleaned up and I made us some dinner. I asked Heather if Brian would be joining us and she responded that he was too busy with his football to bother spending time with her these days. She didn’t seem too upset by it though, and truthfully neither was I. After we ate dinner the girls asked me if I would like them to model their purchases for me. Thinking about the red outfit from Vicki’s I willingly agreed. They started out conservatively, modeling some shirts and pants, and some dresses and skirts. Then they started coming out to show me their new bras, wearing them with skirts or blue jeans and I could feel myself getting aroused again. Soon they were prancing out in bras and panties only and I had stripped down to my boxers (I didn’t want them to feel underdressed). Soon Heather came out wearing the red Christmas lingerie outfit, hat and all and started dancing for me. Cindi came out next wearing a matching outfit and started dancing with her sister very sexily. As they danced the hems of their tops would come up showing me their sexy red thongs.
As Heather and Cindi came up and started dancing around me I muttered something about Brian not being here to enjoy his wife’s new outfits. “Don’t you know,” Heather said, “it’s for you. It was all for you. Cindi knew the whole time that actor was dead.” I was flabbergasted! I looked at Cindi and she just nodded.
“You’ve been stressed, our sex life has become boring, and Heather’s been lonely” she said simply. “Now take off those shorts.”
I happily obliged, once again being completely naked in front of these two beautiful women. They started dancing again, and pretty soon they were making out and feeling each other up while I watched, stroking my again-hard penis. They removed the lingerie from each other and each pressed her body into the other one, legs apart with one leg between the other’s legs. As they kissed they ground their pussies together filling the room with the scent of hot cunt. I took Heather by the shoulders and laid her down on the ground on her back, then led Cindi into a 69 position with her. While I watched they ate each other out, each one with her hands on the other’s hips, grinding together. I got behind Cindi and ran my tongue across the pucker of her ass hole, while her sister tonged her twat. She shuddered in pleasure, and I did it again. My tongue would occasionally run across Heather’s and I could taste my wife on her. I got my wife’s ass good and moist, and then I got up on my knees and placed the tip of my penis right at the edge of her hole, lubing it some more with my pre-cum. We had never tried anal before, so I wasn’t sure how she would take it, but I figured that now was as good a chance as any so I slowly pushed my hard cock into her ass while her own sister ate out her cunt. She froze for a second, understanding what I was doing but not resisting, and I entered her the full 8”. I had never felt anything so tight around my penis in all my life. As she resumed pleasuring her sister I slowly went out and back in again, lubricating her with my juices, then faster and faster. I couldn’t believe that I was actually fucking my wife in the ass, something that she had told me on many occasions would never happen. I felt something warm on the base of my penis, and I realized that Heather had stopped sucking on my wife’s pussy and had wrapped her warm lips and tongue around the base of my penis as I fucked her sister’s ass. Soon enough I could feel an orgasm start to build, but I wasn’t ready to be done yet so I pulled out, leaving my wife’s anus looking open and pink.
“I want to feel that thing inside of me,” Heather said as she pushed me onto my back. She climbed on top of my penis and started riding me, cowgirl style. My beautiful wife lowered her dripping wet pussy onto my face and started face-fucking me as her sister fucked my cock. Facing each other, they started making out with their hands holding onto the others’ breasts for support while they both rode me. As they found a rhythm they really started moving and I could feel another orgasm building up inside of me. I could barely breathe because my wife’s crotch was smothering my face but I didn’t care I just sucked and ate and licked for all I was worth, desperately wanting to get her off with just my mouth. It was successful, and somehow we all managed to come at the same time; I could feel it building in all three of us (and the neighbors could probably hear it). We came, and collapsed, in a great heap of sweat and cum and naked flesh and exhaustion.
We all slept together that night, with me in the middle. At one point I woke up to someone’s mouth around my cock, and another time I awoke with my finger inside a vagina. Heather filed for divorce the next day and moved into our spare bedroom (but she rarely slept there). I continued to be their “slave” for many years to come.
