Your sister is a horny little bitch and is obsessed with getting pregnant so you agree to help her. You've always been a horny stallion and your wife's pussy is kinda old and stretched...she just can't cop as much pounding or loads as your hot sexy little sis and your sisters foul cheeky dirty mouth makes your balls squeeze out cum like it's going out of fashion. *TW frequent use of the I word You pound and pound and pound her for weeks and she starts getting a bit annoyed with her lack of pregnancy. She lets you lay down so your balls can recharge only to arise with lactating tits and wants another deep fuck just to make sure she's properly pregnant before your wife gets .
