Ex brother-in-law was a roadie for a band. One holiday in Miami he is lolling on a chair by the pool, horribly drunk. A young woman swims up and chats with him - looking down at her in the pool with his promiscuous roadie experience and his beer goggles on he thought she looked not too bad. She arranges to come up to his room in 15 minutes, after he clears his buddie out. A knock on the door, and he opens it to a beer-keg of a woman who strides into the room and kicks the door shut behind her. She shoves one hand down his swim trunks and puts the other on the back of his head, and tongues him while squeezing his manhood. He is in shock, but his cock gets hard anyway. She pushes him back to a couch, pulls down his trunks and drops her own swim bottom, and straddles him. Rides him quick and vigourous and hard - he has unprotected sex with a stranger and it takes just a couple of minutes. He was still in shock when she climbs off, he told me.
The guy shakily makes his way into the shower, and is in there with his head against the wall and the water beating down on him. A strong hand reaches around and grabs his limp cock, and vigourously manipulates it while she grinds herself against his back. He is sort of hard and she turns him around, straddles him while standing, and screws him in the shower. When she is done, she leaves and gets dressed. Mentions in passing she is a soldier on a few days leave, and just needed to get her rocks off.
He began to drip a few days later. Yep, STD
He calls it rape - I thought it was tacky and sick, but that he did set himself up.
