This is for the ladies. Tell your parter you are not on Birth Control so he must pull out, but you really are on BC. Then till him you only do it missionary. Right as he's about to pull out wrap your legs around him and say somethingfucked up like " I want you to be my baby's daddy"
Guy: Oh baby Ima pull out......take your legs off me.
Girl: BE MY BABY'S DADDY
Guy: Dude, had a pregnancy scare. she said she wasn't on BC and wrapped her legs around me like a Boa Constrictor as I was about to cum.
A girls riding your cock cow girl style. She drank to much and she starts vomiting. Every vomit causes her vagina to tighten. Resulting in a tight snake like sensation on ones cock.
