The scene starts with mommy riding your cock, you have that kind of relationship, mommy loves to bounce and grind her hips on your boner, feeling her sons swollen cock inside her pussy. You blow your load, draining your balls of cum inside mommy..... she instantly feels pregnant. You tell her she can't possibly feel pregnant already, but it's true, she can feel the milk rushing to her tits, her big mommy milkers expanding. She takes a breath, and there they are. Huge titties full of milk. You grow hard again inside her, you're hornier than ever for her pregnancy tits, big full heavy tits bouncing in your face
