I'll bite. By far and away the grossest/worst/weirdest experience of my life. It was my senior year of college and the first weekend all the students were back at school. I was in a little bit of a dry spell. Not many students stayed over the summer so it was slim pickens. Anyways, I met some freshmen at a party. On my scale, I will give her a yellow light. Which means, she's average but looks hot after a few beers and definitely bangable. She was cute enough, blonde, tan, etc. We hit it off at this party which was basically a pre game before we hit some some other parties. She's feeling me and I was looking for that warm hole so I invited her along. We get to the party and a couple of my buddies start talking her up and tell her I have the big dick on campus. She's been drinking and completely believes it, so now she really wants the dong. Big dick on campus is a complete lie, I'm a pretty average guy, 5'10" 175lbs, so I'm definitely not walking around with a jackhammer. Whatever, that just made it so much easier. I get her back to my place, both completely trashed at this point. We're in my bed and start making out and I got to take her pants off and she says, lets go back to my dorm room. I asked her why and she said she just felt more comfortable there. More to come on this. So I didn't really think much of it and it wasn't a long walk so we head to her dorm room. We get back there and get in the room and she immediately turns off the lights, takes off her clothes and starts messing around with her vag. By messing around with her vag, I mean she was taking out a tampon, which I didn't notice at the time due to the drunkness/darnkness. The reason she wanted to go back to her place we so she could A. Take out her tampon and B. Have a tampon afterwards. We climb up to her stupid bunkbed and start making out again and I contemplate going down on her but out of the blue she goes, just get a condom and **** me. I'm like hell yeah. So I climb down the fucking bed, grab the condom, and we start banging. I was hammered so we just started in missionary. After a couple mins, I was bored as **** and I flip her over. Her shades had just been slightly pulled open and the moonlight was shining through. I could see something running down her leg. Assuming she hadn't gotten off yet, I was like wtf is that? She goes "Oh I forgot to mention that I'm on my period." I gagged a little, climbed off the bed, through the condom on the floor, and told her I needed a beer. Haven't talked to her sense.
