Fucked my housemates younger sister [MF]

I have lived with my housemate Kayla (27yo) for about a year and we get along great. While I find her attractive, it has never crossed the line of more than housemates. A couple of weeks back Kayla asked if I would mind if her younger sister Lea (20yo) could stay at the apartment while she was visiting from out of state. I agreed and even helped pump up the air mattress for her to sleep on.

​

Lea arrives and she is extremely similar looking to Kayla. Short, at about 5’3, with dark hair and tan skin, big brown eyes and a nice smile. Lea is petite, especially on her upper body, but has a perky bubble butt and gymnast legs. She is essentially just a younger version of Kayla, but with a less mature body and less body fat (i.e noticeably smaller tits). I figured out quite quickly that Lea also has similar personality traits to Kayla, they are both very friendly but can be stubborn and uptight at times.

​

The first day goes by and I couldnt help but feel that Lea was mildly flirting with me, but brushed it off convincing myself it was probably me flirting and her just being friendly. The third night rolls around and we head out for dinner & drinks with some other friends. By the time we get home we are all quite tipsy and I feel the flirting had intensified. As Kayla was in the bathroom, Lea and I inadvertently brushed against each other in the kitchen. The eye contact and sexual tension was palpable after feeling her brush against my torso. Lea tipsy-ly tugged at my shirt, then leaned forward whispering goodnight in my ear. Her next move was to jokingly kiss me on the cheek, but she couldnt quite reach up to my face (I am 6’2), slipping down she accidentally kissed my neck. Pulling away, biting her lip and say ‘ooops’ was all the confirmation I needed. Lea had her ‘fuck me’ eyes on. Kayla returned to the room, which stopped our brief encounter. I went to bed thinking about fucking Lea.

​

The next day went by and you could cut the air with a knife for the sexual tension that was between Lea and I, however we didnt have the chance to act on in. The following day over breakfast we were discussing Kayla having to go to work, Lea said she would go jogging and then chill, I was going to be home with not many plans for the day. Kayla left for work, with me sitting on the couch in the living room, a few minutes later Lea appeared in tight running shorts and a crop top – looking extremely sexy. After about 30 seconds of small talk, we were suddenly standing in the middle of the room inches away from each other, sexual tension going wild. I jokingly asked Lea “how about we do a home workout instead of jogging”.. to which she let out a sigh “I thought you would never ask”.

​

Moments later I had Lea stripped down to nothing but a tiny black thong. Admiring how impressively her bubble butt stuck out from below her waist (which happened to have perfect back dimples – yum!), and her perky little tits with erect nipples. I was kissing up and down her body, before throwing her small frame on to the couch. Spreading her legs and teasing all around her thighs, tasting the small wet patch on her thong. With the intention of moving her thong to the side I pulled hard at it. Too hard. It tore a little. Which just encouraged me to rip it off completely. This made Lea let out a whimper and pull at my hair.

​

For the next ten minutes I ate Leas pink pussy until her head was tilting back, moaning herself to an orgasm. Letting her catch her breathe, I sat down next to her, dropping my pants in the process. Lea excitedly dropped to her knees and began immediately sucking my cock. Enthusiastically bobbing her head up and down. I ran my hands through her hair telling her how good she was, which just encouraged her more. After a while, I pulled her up off me. Standing back up, I picked her up and placed her down on the couch kneeling in front of me.

​

Lea was holding the backrest of the couch, sticking her ass out in the air, and looking back over her shoulder as I stood behind her slapping my cock against her round ass cheeks, pulling them apart to reveal her tight pussy and asshole. Her pussy was still wet, as I eased myself inside her. After a gentle start she got used to me, and I was fucking her with long hard strokes, gradually increasing the pace. Eventually Lea was holding on to the couch for dear life as I was thrusting in and spanking, listening to her moans grow louder and her dirty talk increasing, out of nowhere telling me she wanted to be slut for me. The furious fucking finally led to Lea having another orgasm. She had to push me off because she was too sensitive to take any more.

​

But immediately she span around, dropped to her knees and took me in her mouth again. This time holding me hips and rocking them, beckoning me to thrust into her mouth. I didnt hesitate. I was fucking her mouth slow and steady as her saliva dribbled down her chin. The sight caused me to erupt in her mouth, which she swallowed smoothly before looking up at me giggling.

​

We then stopped for a bit, chilling naked and having a glass of water on the couch. Lea eventually stood up to go to the kitchen but the sight of her ass right in front of my face washed a whole new layer of horny over me. I grabbed her hips and pulled her back to me, burying my face in her ass. My tongue deliberately wandered to her asshole, which she was surprised at but moaned and told me not to stop. Within minutes of her bending over in front of me, her pussy was soaked again. This time, I picked her up and put her on her back on the couch. Lifting her legs up and wrapping the around my waist I entered her again. Due to the height difference she was essentially hanging off my body, with just her shoulders resting on the couch, her legs clenched around my waist as I held her hips up nice and high. We fucked like this for a while until she was moaning loudly again, before I pinned her down on the couch again in prone position and fucked her with my hips slapping against her ass. This time I was about to cum, thinking of pulling out, she moaned for me to fill her with my cum. I held her hips and filled her with a load of cum before collapsing on top of her.

​

We were a bit exhausted and she was sensitive so we had a few hours break before fucking again once more, this time in my bed, just before Kayla returned from work. We cleaned up and gathered ourselves, by the time Kayla arrived we were sitting on the couch acting as if nothing had ever happened. Kayla joined us for a beer on the couch, and all I could think of was that a few hours ago I was filling up her little sister right there. It was hot.

​

Lea left the following day and we didnt get a chance to fuck again, but she has been sexting me and saying how hot it was. But that we cannot tell Kayla because she would certainly not approve! While the thing between me and Lea is purely sexual, I cant help but wonder what it would be like to fuck Kayla and if she is as sexual as her younger sister. Kayla is non the wiser that Lea and I had a day of wild fucking, and I hope she doesnt find out anytime soon, so Lea can come and ‘visit’ again!
