In the dimly lit room, a curious threesome begins. The girlfriend, her pussy already wet with anticipation, spreads her legs wide as her boyfriend and their lover hold the light, illuminating her glistening folds. The lover leans in, his tongue eagerly exploring her slit, lapping at her juices. The girlfriend moans, her body writhing with pleasure as the boyfriend watches, his cock hardening. The night is young, and the marathon of fucking has just begun.
