Scene One: One and one kryptonian
“Aren't you worried that we're the last kryptonians Clark? That our race will just off” SuperGurl asks her cousin. He's thought about it before but doesn't know how to help it. “I need you to impregnate me” She tells him. Clark looks at her in disbelief. “It won't be cheating on Lois” SuperGurl says grabbing Superman's dick through his underwear.
He tries to pull away but she won't let him go. She's doing this for her people, for her race, she's going to get pregnant by her cousin, she doesn't care if he wants it or not. She puts his cock in her mouth and sucks him until he's hard. Properly motivated he pushes her down on the bed and his way inside of her. Supergurl moans, never being fucked like this before. “Fuck my super pussy nice and hard” She screams at him.
Scene Two: Make three kryptonians
Superman holds her legs up high and pushes his cock into her ass. SuperGurl's eyes go wide as she feels him stretch her tight ass out with his big cock. No mortal man has ever had the strength to fuck her ass before and it feels amazing. On the edge of oblivion she will do anything to cum, even suck Superman's dirty cock.
She gets on top of him and rides him, his hard dick pounding into her tight warm asshole. She looks up at the ceiling and cums with an earth quaking orgasm. He fucks her ass and pussy in every position imaginable, showing her why Lois married him, until he shoots a huge load inside of her. “You filled me full of your cum” Supergurl moans in pleasure. “I'm doing this for Krypton”
