Ok, so this isn't a well-crafted story, but I just wanted to describe how my ex and I used to do it sometimes, a few years ago now. It turns me on to remember it. This was back when we both lived with our parents, and opportunities were more scarce. My GF was young, early twenties, petite and quite pretty. She wasn't "perfect", but she definitely got me hot. And she had a bit of a dirty streak. The sort of thing that would happen is this: we'd be sat around in the living room of my parents house on a Saturday (for example). My parents would be around the house, but not right on top of us or anything. My GF would say something like "Shall we go upstairs to your room…?" I would know exactly what she meant and get really excited at the prospect. So naturally we would make our way upstairs to my bedroom, without any fuss, and close the door. Then there'd probably be a conversation along the lines of "we have to be quick and really quiet so your parents don't know", which was absolutely fine by me as I would be so horny I'd just want to fuck. So then we'd get down to it: Usually little to zero foreplay. I'd get my pants and underwear off, already really hard, and a condom out of my wallet, straight onto my penis. While I'm doing this I'm getting even more excited at the sight of her taking her jeans off, or pulling her skirt up to her waist, and her cotton panties falling to her ankles, or panties sometimes just pulled to one side. Then she'd either lie back on the bed, or get on all fours on the bed, and give me a look as if to say "what are you waiting for?". Can you imagine how horny I'd be having this elicit encounter with my young girlfriend in the middle of the day? The sight of her naked lower body. Her pale goosebumped skin. The hairy mound between her parted legs. We'd usually both still be wearing our top half clothing. There might be a quick bit of kissing and fumbling, or sometimes I would put my tongue between her legs for a minute or two. I might unclasp her bra underneath her T-shirt without taking it off and quickly fondle her soft breasts and hard nipples. But mostly it was about the fucking. I'd enter her bit by bit at first (no artificial lube required…) and then start to pump rhythmically and deeply, but not with so much force or speed so as to make any noise. Quite possibly I'd be overhearing my parents talking elsewhere in the house. No, I wouldn't make a sound, but my girlfriend would know I was horny as hell. My rock hard penis and my urgent thrusting told her that much. All I would know from her in return would be the quick, shallow breaths she would take, her closed eyes, her open lips, her natural wetness between her legs and the pink flush spreading down her neck. So we would fuck like that, quietly, urgently, and to be honest it would probably be less than five minutes (or even considerably shorter: I was a young guy, and so turned on) before I would feel the tightening in my balls and I would fill up the condom, utterly fulfilled. I'm pretty sure my GF would enjoy these encounters too. Sometimes I would gently finger her afterwards until she came, quietly. But she didn't always want to if she was anxious about parents being around. All in all these experiences were so fucking sexy precisely because we had to be quick and quiet. Sometimes I wish I could still have that kind of sex, but it's no longer necessary, unfortunately!
