In the spirit of Cinco de Mayo, a group of gay men transform a city bus into a mobile party, complete with music, laughter, and a generous helping of gay sex. The twinks, their inhibitions lowered by the festive atmosphere, can't resist the urge to touch, kiss, and flirt with one another, their hands wandering and erections prominent. The sight of their hard, leaking cocks and the sound of their wet, sloppy kisses only serve to fuel the fire of their desire.
