My cock twitched inside Deb’s slippery rectum when she told me about their first year of college, when their lesbian activities reached their peak. Dana had always been interested in having sex with a girl, and she did it repeatedly during their freshman year. Deb wasn’t as drawn to lesbian sex as her sister seemed to be, but she was curious and she didn’t want Dana to be more sexually experienced than she was.
Once again, Deb requested Dana’s help. Deb’s idea was that Dana might hook her up with one of her new girlfriends, someone suited for her, gentle and discreet. Dana wouldn’t have any of that. Since Deb wasn’t really into girls and she didn’t want people to know about her experimentation, Dana convinced her that the best course of action would be for the two of them to have sex. After all, they had done stuff before. Knowing she could trust her twin, Deb accepted.
My head was spinning as my babe told me about licking her sister, getting her pussy thoroughly and voraciously eaten out by Dana and getting each other off while locked in a sixty-nine. She chuckled as she said that Dana really got off on licking pussy, just like Deb herself did on giving blowjobs.
“So… Aaaah fuck! So how was it, babe?” I asked, throbbing hard and gasping with arousal.
Deb shrugged, making her heavy tits jiggle as she bounced her ass on my cock. “It was okay I guess… Oooohhh! Dana was really into it, way more than me… Uuuhhh fuck! We did it a few times, and that was good enough for me, but… Ooooh yeah, baby, push your cock up my ass aaaahhh! But she kept offering to lick my pussy if I wanted, until I started dating… Uuuhh!… She seemed upset whenever I brought home some guy… Aaahhh fuck yeaaahh, you’re so deep in my ass! But by our second year she was back to boys too, so… Uuuuhhh yeah, harder, fuck my ass hard, baby!”
Now, I like to fantasize about two girls going at it as much as the next guy, and I’ve read my fair share of incest stories too. Still, I never thought I’d actually get so close to the real thing. I wasn’t lying to Debs when I told her that I didn’t have any interest in fucking her sister. But this was quite different. My girlfriend and her twin dyking out? It was hot. Incredibly hot. My pulsing dick testified to my increasing arousal.
Deb obviously felt that her tales of sisterly incest were turning me on. As she kept sliding her asshole up and down my hard meat, she smiled sultrily and said: “Mmmh, it seems like you’re enjoying my stories, baby… Would you like to see us eat each other out, right here, in front of you? Uuuhhh yes, keep fucking my ass!… Would you like to see my sister licking my pussy, baby? I know she’d love to. I bet she wants to eat my pussy just as much as she wants your cock in her ass, even more maybe. Aaaahhh fuck yes, faster, like that, long and deep!… Wouldn’t you like to stick your big fat cock up Dana’s tight virgin asshole after I licked it and made it all wet and ready for you, baby? Mmmh… I’d love to have her eat my pussy out while you fuck me in the ass… That would be so ooooooh fuuuck!… Sooooo hot! UUUUHHH!”
That was just too much. I bucked my hips up into Deb’s pliant anus as hard and fast as possible while she frantically tortured her clit with her fingers, whimpering and pumping her hips to meet my thrust. I pistoned full force into her rectum, sinking my hands into her juicy buttcheeks, until I felt my balls draw up and I started spurting jet after jet of cum deep in her ass. The feel of my cock swelling up and sending ropes of cum splashing against her anal walls pushed Deb over the edge. With a choked squeal she impaled her asshole one last time on my ejaculating shaft, shivering all over, gasping and crying out in orgasm while her rectum pulsated and contracted around me, milking me until I was drained of every last dribble of seed.

In the following days, Deb never lost a chance to conjure up naughty lesbian scenarios for me. She was obviously getting a kick out of the idea of us having a threesome with her sister. And now she knew that, despite not being interested in Dana herself, I had a weakness for the idea of the two of them dyking out.
Either when we were having sex or to tease me into having sex, my babe described all sorts of lesbian acts involving herself and her sister. I wasn’t sure if what she told me was a recollection of past events between them or just some hot incestuous fantasy she concocted at the moment, but I didn’t care. My reactions to Deb’s tales were always very enthusiastic. It was insanely hot to pound my girlfriend’s pussy or ass while listening to her murmur about the two of us fucking her twin sister and making her service us like a good bisexual slut. That was hands down my favorite fantasy involving Dana and I came like a geyser whenever Debs evoked it.
When I finally asked Deb if she was kidding about Dana having a submissive streak, she just shrugged and said: “I think so. She’s sort of into pain, I can tell you that. She likes to be spanked, hard. And when I played with her tits, she didn’t just want me to tweak her nipples. She asked me to really pinch them and twist them, pulling on them until it hurt. It was a bit weird, but she always went crazy when I did that. So yeah,” she concluded with an impish grin, “my guess is that we could easily make her into our little fuck-toy. Just say the word, baby…”
And of course I did. After three days of animalistic fucking fueled by fantasies of sisterly incest and whatnot, I caved. I agreed to have a threesome with my girlfriend and her twin so that I could pop Dana’s anal cherry without technically cheating on my babe. Funny thing is, at that point I didn’t even found it too strange anymore. Just a bit.

The night after I accepted to go through with it, I met the girls at their family’s art gallery after work. Deb was wearing a dark pencil skirt that hugged her magnificent ass amazingly and an elegant white blouse that strained to contain her bodacious boobs. Dana had opted for a stylish crop top and a pair of tight fitting jeans that showcased her long toned legs and taut butt. She had dyed her shoulder-length hair ash blonde since the last time I saw her the previous week, while Debs had her own long light brown locks tied in a ponytail. They were both wearing heels.
The plan was to go get dinner together at an Italian place the girls liked, as we usually did at least every over week, and then return to our place for ‘dessert’. That part was definitely new and more hazy as to the details. Deb had made it sound very easy when we had picked the night and I asked her how exactly this was going to work. She had just laughed and said that I shouldn’t worry about anything, she’d handle Dana and all I had to do was follow her lead.
All through dinner we chatted and traded morsels of our orders as usual, commenting on the food and talking about friends and work. As always, Dana was the center of the conversation, with Deb and me remarking here and there. That night though, Dana’s frequent laughs sounded a bit strained, her typical bubbly enthusiasm appearing forced and somehow fake. I noticed her stealing glances at me more than once when she though I wasn’t looking. She also seemed to be touching Deb way more often than she usually did, lingering every time their bodies brushed together accidentally and resting her fingers on the back of Deb’s hand for long seconds to attract her attention.
