Your horny, very fertile girlfriend wants your potent seed so she can get pregnant

(Custom fantasy, the name "Greg" used.) You come home from a long day of work to find your girlfriend laying on the bed playing with herself. She's wearing a black teddy, garter belt & stockings. She's so happy to see you, so horny & her body is extremely fertile. She wants you to get her pregnant! First she takes your cock in her mouth, your balls so filled with cum. She wants to feel an explosion of creamy cum inside her. She kisses your cock & says naughty things. Teases you. Sucks you deep. She gets hornier & hornier, begging for it. She straddles you. It feels so good when your dick is right at the entrance of her wet pussy. She's going to fuck the cum out of you. Put a bb inside her. She takes it deep & tries different positions until you cum together. Her orgasmic convulsions suck your hot load deep into her body as she moans in ecstasy...
