Flip and Bip starts when a male and female are having sex. the girl is on her back and the man is on top. when the man starts to orgasm, He then lifts the girl up and tries to spin her around ( while she is still on his dick ) and turn her onto her stomach before he cums. This is often very hard and very painful, but can be extremly fun.
Sarah: my boyfriend is so strong and he is soooo good in the sac. last night, we did the Flip and Bib.
Anna: wow. didnt it hurt?
Sarah: a little for me, but today my boyfriend is walking around with a limp.
