Eric's pulse races as he sinks into Zelex's inviting warmth, her realistic pussy hugging his cock like a glove. He grunts, thrusting harder, his hips smacking against her firm ass. The sex doll's lifelike responses fuel his desire, and he pinches her hard nipples, leaving red marks on her silicone skin. Eric's body tenses, and with a final, forceful stroke, he erupts, his cock pulsing as he covers Zelex's generous tits with thick, creamy cum.
