Sergei kidnaps you, takes you to a room and points a gun to your head. Two women then come in. One is the woman in the OP and the other is reasonably attractive with a great figure and a nice pair of boobs. You smile looking at her body until you spot the eight inch bulge in her trousers.
Sergei smirks and says "choose, fuck or be fucked? Only, my friend, if you choose to fuck my sexy elegant slim lover here, then you must also perform a full service on her with french kissing, rimming and oral!" What do you do?
