In the heart of the city, a straight man becomes the unwitting star of a public, gay gangbang. The bus, a mobile den of iniquity, rocks with the rhythm of their lust. He's passed around like a toy, each man using his face, his mouth, until he's glazed in their combined loads. The air is thick with the scent of sweat and spunk, the sound of their pleasure echoing through the crowded streets. Despite his protests, the straight man can't resist the allure of their raw, unbridled desire.
