You come home from school to find your mom Jackie on the phone to her twin sister Jenny. Jenny's upset to find out that her fiance has been cheating on her, he was her last hope of getting pregnant before the summer. Mom & aunt Jenny have an idea though - Jackie hangs up the phone to tell you all about it. Mom wants you to go over to your aunts house and get her pregnant. Mom has seen the way you look at your busty aunt, she knows you'd be up for the challenge of filling her womb with your seed, but she can see you're a bit shy. Well, since she's your aunt's identical twin, mommy suggests you practice with her. It's important you don't cum too quick in your aunt as you want her to have an orgasm to ensure she'll get pregnant. It's safe to fuck your mother as she's on the pill & it'd be great practice filling her pussy with your seed before you give it to your aunt. Next thing you know, your mother is riding your hard young cock and making you cum in her over & over. After she's taken several loads in her hairy pussy, mom sends you off to go clean up & get to your aunt's for her impregnation. Jackie calls Jenny to tell her you're on your way but she notices something strange about her birth control pills - they aren't birth control at all! Oops! Looks like mommy & auntie are going to be identical in every way, baby bumps & all!
