In this steamy tale of forbidden desire, a young man finds himself alone with his step-sister, who happens to be a few months pregnant. As he helps her undress for a massage, he discovers a hidden surprise - she's wearing sexy lingerie beneath her loose-fitting top. Intrigued and aroused, he can't resist the temptation to explore further. He begins to massage her lower belly, his hands wandering over her rounded stomach, teasing her sensitive skin. She moans in pleasure, her body responding to his touch. Soon, he's kissing her neck, his hands exploring her bra, and before long, he's unleashing his throbbing cock from his pants. He positions himself near her, ready to fulfill her secret fetish. With a gasp, she takes him in, stroking and sucking until she's ready to cum. And when she finally does, it's a sight to behold.
