The bus's motion rocks the two twinks, their bodies pressed together, hands exploring. The first twink, his breath hitching, guides the other's hand to his crotch, feeling the growing bulge. They stand, facing each other, lips locked, as they grind their hips. The second twink unzips the first, pushing his hand inside to grip his throbbing cock. They move to the back of the bus, the first twink bending over, his ass presented. The second twink spits, rubbing his saliva into the tight hole before pushing his cock in, fucking him hard, the bus's motion amplifying their pleasure.
