This was my senior year of high school. My girlfriend at the time was really into rough sex and also almost being caught.
One Monday morning before school I drove over to her house at about 5am. School started at 7:45am giving us just enough time to get freaky. So I sneak into her house and into her room without her family hearing (I knew where the spare key was hidden). I slip into her room and kiss her awake (She knew I was coming over in the morning but wasn't sure as to when). As she wakes up, she gets insatiably horny. She grabs me and begins to kiss me. I slip my hand into her pants and start to gently rub her clit. This does the trick and within minutes she's tensing up and cumming all over my hand. After she came she stripped herself and then myself down. I'm standing up next to the bed as she starts to blow me.
Right as she begins to deepthroat my dick, her dad knocks on the door to say goodbye before he goes to work. Fortunately I had locked the door when I entered. She begins to rub her clit at the prospect of being caught by her father all while still sucking on my cock.
At that moment she takes my dick out of her mouth, looks up at me and begs me to fuck her. I oblige and pick her up to toss her on her back. As soon as her ass hits the bed, I'm already on top of her kissing her neck, positioning myself at her entrance. I push in and slide all the way down. She lets out a soft but audible moan. As I pick up my pace I can feel her grip tighten on my back, nails digging in. I slammed into her harder and faster the more her nails dug in. Finally, as I'm thrusting at full force, I lean down and bite her neck. She was always super into biting, whether she was on the receiving end or not. Now she liked it really rough so as I begin to bite down she begging for it harder, the bite, not the fucking. It got to the point where I broke skin and she began to bleed profusely. The shock of the pain was enough to set her over the edge and she had to bite down on my neck area to stiffle her screams, as her whole family was still in the house. I did not let up on the fucking though. I still pounded her all throughout her orgasm which caused her to bite down harder. Eventually she too broke skin. I felt the warm blood run down my chest as I pumped into her. Just as I was reaching my peak, I hear her mom outside her door moving around the house, getting ready for the day. My girlfriend must've heard her mom too because she began begging me to come inside of her while her family was outside. She wrapped her legs around me and began to force me into her even more. Finally, I pushed as deep as I could and she gripped me tightly as I pumped rope after rope of thick cum into her. When we finally caught our breath, we realized that we were covered in each others blood and sweat. We basically looked like we had just fucked each other in slaughter house.
She was very turned on by this as was I and things started to heat up again. By this time I realized that we needed to get ready for school, so I started kissing her hard and fast all whilst picking her up and taking her to the shower. In the shower we fucked one more time before cleaning each other off, getting ready and patching up our puncture wounds with some gauze and medical tape. It was kind of hard to explain what happened to my neck to anyone that asked.
TL;DR I fucked my girlfriend in a pool of our blood while her Parents probably listened.
