Siri Dahl, heavily pregnant and craving intimacy, arranges a private massage with her husband Robby's friend, Codi Vore. As Codi's skilled hands work Siri's tense muscles, the two women can't help but feel the spark between them. Robby, returning home unexpectedly, catches them entwined, Siri's large, pregnant belly pressed against Codi's as they kiss passionately. Instead of interrupting, he joins in, his straight cock hardening at the sight of the two beautiful women together. The threesome explodes into a frenzy of lesbian pleasure and straight cock worship, with Siri's preggo belly rubbing against Codi's and Robby's throbbing member.
