Cheating with my flat-mate in the middle of the night [MF]

I found myself thinking, OK wanking, about Sarah this morning and thought I’d write this experience down.

After I finished my degree, I started a post-grad and my girlfriend [Jess](https://www.reddit.com/r/gonewildstories/comments/gv7ne9/summer_sex_in_the_long_grass_mf/) did a year’s work placement abroad. I took a room in a flat-share with a couple of girls I knew, Olive my friend’s GF, and Sarah her friend.

Now Sarah and I had got hot and heavy one night before I met Jess, just kissing and hands everywhere but nothing more. I didn’t tell Jess this fact when I moved in with them. Jess came to help me unpack the weekend I moved in, and the Sunday morning before she left, we had some good parting sex in my room. Jess used to moan stuff to me like ‘fuck me, harder, harder’ and I suppose we were a bit noisy. When we wandered into the open plan lounge-kitchen, Sarah was sat with a cup of tea and gave me a bit of a smirk. and I guess she’d heard us fucking from down the hall. I gave a slightly embarrassed grin back. The weeks passed, with Jess abroad and the three of us busy on our courses. We’d hang out together in the lounge most evenings, watching TV, and I enjoyed spending time with the two girls.

Most mornings, the girls would use the bathroom first, and I’d finally get my turn last. One morning I wandered down to the bathroom and the door was slightly open, which we did to let the room dry, so I pushed the door open. Sarah was stood facing way from me at the basin mirror with a dark green towel over her head drying her short cropped black hair. My eyes quickly went into that kind of super slo-mo mode and I quickly checked her out. Her hips and dripping wet bum, and in the mirror, the two pert little tits I’d felt when we’d been making out, a tattoo on her waist, and trimmed little black bush between her toned, curvy thighs.

No sooner had my eyes taken this in then Sarah spotted me in the mirror. “Shit, sorry Sarah” I said, and quickly backed out of the door and went back to my room. I was still thinking about her naked body when she knocked on the door. “All yours” she said. I came out of my room to see her wandering down the hall wrapped in a towel. I went to the bathroom and wasted no time in grabbing a blob of conditioner and rubbing one out, thinking about fucking her over the bathroom basin, quickly squirting a thick load into my hand under the shower. Nothing more was said about it, though images of Sarah naked in the bathroom kept on popping into my head that day.

About a week later, I got up in the middle of the night to get a glass of water. I wandered into the kitchen just wearing my boxers. As I filled the glass at the sink, a voice behind me said “Hi”. I jumped a little and turned round to see Sarah standing right behind me, wearing a little grey vest and shorts. “Hi” I whispered in reply. I was suddenly conscious of being half naked in front of her when Sarah’s eyes glanced down at my subsiding night-time erection hanging sideways in by shorts

“Sorry about walking in on you the other morning” I said, feeling it was a good time to mention it in a moment of half nakedness. “Don’t worry, I won’t tell Jess you were perving on me in the bathroom” Sarah joked. I told her I wasn’t perving, which was half true. She replied “But you had a good look didn’t you?”. I laughed and whispered “Ok, yeah I got a great look. I didn’t know you had a tattoo”, letting her know how much I’d seen. Sarah stepped closer to me, so we were only about a foot apart “This one?” then lifted her vest and pulled her shorts down a little. I giggled, and felt that rush of excitement, hormones and the sudden return of my erection as she revealed the tattoo. I could see she didn’t have knickers on under the shorts, and I’d already started thinking about touching her. “Yeah, that’s the one”.

I can’t remember if she touched me first, reaching for my bulging cock, or I whether I stroked her tattoo, but a second later we were kissing and had our hands all over each other. My hand reached down into her shorts and found her pussy was already pretty wet. I knew I was going to fuck her, I knew it was wrong to cheat on Jess but I wanted to have her right then. Sarah knelt down and started sucking me as I stood there in the kitchen. I let her suck me for a minute, taking in the randomness, then pulled her up and led her by the hand back into her bedroom. I pulled my boxers off over my raging hard dick, pulled down her shorts and pushed her back onto her bed, climbed on top of her and pretty much just plunged my cock into her without a thought of a condom.

Sarah moaned a loud moan as I fully entered her. I held her firmly and began fucking her hard. “God I wanted you inside me for ages” she groaned in my ear as we fucked. I looked down at her pussy as my length slid in and out, noticing the difference with her pussy lips and Jess’s. Hers being plumper and more pronounced. After a couple of minutes, Sarah began to breath faster. “Don’t cum yet” she said as she sensed I was getting close. I switched to some short fast strokes that hit Sarah’s g-spot and she came, gripping me tight and really scratching her nails on my back. As her orgasm finished, I thrust deeply a couple more times and then pulled out. She grabbed my cock just as it started squirting an absolutely massive load all over her vest. She stroked me until I’d finished, took of her cummy vest, and we collapsed together on the bed.

The feeling of guilt didn’t take long to surface and I felt pretty bad post-sex as we lay in bed. Sarah reassured me she it could be our secret but I wasn’t too feeling too confident. That said, we cuddled together for a while before I started to get hard again against Sarah’s back. Without saying anything, Sarah grabbed hold of my cock and guided it back into her still wet pussy, both us us moaning as we started fucking again, this time taking much longer that the previous quicky. I played with her clit as we spooned and she came once before having a second stronger vaginal orgasm. I was worried Olive might hear us as Sarah moaned loudly at what was probably 3am in the morning. As I got close to cumming, I pulled out and lay back and Sarah turned round and began to suck me, and it wasn’t long before she finished me off in her mouth, swallowing every drop. After a couple of minutes, I told Sarah it had been great but it couldn’t become a regular thing. She agreed and I headed back to my room for the rest of the night.

I don’t think Olive heard us and things carried on pretty much as usual in the flat but a few nights later, I was asleep when Sarah crept into my room. The first thing I knew was her climbing under the sheets with me as I woke up. She was wearing a PJ top and knickers and immediately reached for my cock, which quickly stiffened as she stroked under my boxers. “I’ve been in bed thinking about your cock” she whispered and guided my hand to her soaking wet knickers. Still half asleep, I fingered her as she stroked me and I began to tell her how I’d masturbated after seeing her in the shower. She got really turned on hearing that, and told me she’d masturbated after hearing Jess and I fucking. Sarah made me tell her in detail about jerking off to her as I played with her clit. She orgasmed under my fingers as I described my shower session in her ear, telling her how I wanted to fuck her in front of the mirror. I pulled her knickers down and told her to turn over and guided her up onto all fours into the doggy position and fucked her hard and quiet in the dark. She panted into the pillow as I grabbed her hips and gave her a deep, hard fucking with all my 7 inches until she came again, this time moaning more quietly . I wanted to cum inside her so badly but had no idea if she was on the pill, so pulled out and asked her to suck me. I came almost immediately in her mouth, surprising her as she’d just got her mouth round my bulging spurting head. This time Sarah left and went back to her room.

That was the last time we had sex. I told her we couldn’t carry on, and she got a BF a while later which helped stop things continuing. It was fun hearing them fucking from time to time , and I jerked off to them once too when she was being noisy, wondering what position she was in in her bedroom. Thankfully, those couple of fucks remained our secret and Jess never knew. I felt bad at the time but now it’s just a fun memory of some great middle of the night fuckings.
