Your Ex GF shows up at your place, and, of course, she has a favour to ask of you. This one's pretty big though - she wants to impregnate her. Her attempts with her current partner haven't worked so she thought you could be the perfect biological father to her baby. Don't worry though, you wouldn't have to do anything - just make sure she's filled with your creamy cum, and maybe come and fuck her from time to time while she's pregnant. You don't have to do anything related to raising the baby either - no support, no parenting; you're truly off the hook. She knows you miss having sex with her, and that this could be the time you finally get to fuck her without a condom. Don't you want to experience no-strings-attached bareback sex with your favourite ex? She starts riding you once you agree, telling you how badly she wants your insemination smoothie inside her hot cunt. Her eggs are begging for your fertile load and she won't stop until she gets it. Moving to missionary, she looks you in the eyes as you fuck her down, letting you know how fucking better you are than her current partner. Fuck, she's missed your cock. You cum inside her pussy and she thanks you for your service.
