You and your wife hire a surrogate mother to have her womb filled with your wife’s eggs. In return she is wants to be injected with your cum naturally but you will use your wife first as your own cock sleeve. She tells your wife to suck you off as the new woman plays with herself and tells you to look at her and let your wife just become your personal fuck meat. As you are really close she spreads herself for you but you fuck her ass instead and reject her cunt and cum in her ass. She tells your wife to clean it up and to put the cum into her pussy and you will have to work on this with her again.
