As the evening wore on, the three adults found themselves sharing drinks and laughter in a cozy living room. The aunt and her niece were particularly flirty, constantly brushing against each other or playfully pinching one another's sides. Their friend's well-endowed boyfriend couldn't help but notice their antics, his eyes lingering on the women's curvy figures whenever they moved.
Despite his initial reservations about getting involved with his girlfriend's family, something about the teasing atmosphere and sexual tension in the room made him feel brave. Slowly, he began to inch closer to the trio, his hardening erection noticeable beneath his pants.
Without warning, the aunt casually moved closer to him and pressed her lithe body against his rigid length. Her breasts grazed against his chest as she whispered suggestively in his ear, causing a shiver to run down his spine.
