Craving a threesome, I invite my girlfriend's twin sister over, keeping it a secret from them both. As they innocently chat, I can't help but imagine their identical bodies writhing beneath me. My girlfriend, catching my wandering eye, playfully asks what I'm thinking. I confess my fantasy, and to my surprise, her twin eagerly joins in. We move to the bedroom, where I watch, hard as a rock, as they kiss and caress each other. The room fills with their moans as I fuck them both, their tight pussies clenching around my cock. We switch positions, and I can barely hold back as they lick each other's juices off my shaft.
