Horny old men can't resist Diana Lane's massive, jiggling breasts on the crowded bus. In a tight, low-cut top, she inadvertently teases them, fueling their lust. They grope her, their hands squeezing her big boobs, their cocks hardening against her. Diana, shocked and aroused, doesn't push them away, her nipples stiffening under their touch. Alex Frenk, a fellow passenger, notices her discomfort and intervenes, reclaiming her space, leaving the old men unsatisfied and Diana breathless with taboo excitement.
