Friends since forever, they've never crossed the line. But today, the sun's intensity and the liquor's courage make them brave. They're alone, the house empty, and their bodies ache with unspoken desires. She reaches out, cupping his friend's breast, feeling the softness, the fullness. He hardens, watching her touch herself, her fingers teasing her nipples. She notices, biting her lip, her hand straying down to her pussy. He can't help but follow, his own hand rubbing his cock through his swim trunks. They lock eyes, the unspoken question hanging in the air. This time, there's no hesitation, no pausing to think. They give in to their urges, their bodies entwined, their moans echoing through the empty house.
