The Late Picture Show (1980)

In the dark movie house, Wren spotted Kevin right away and moved in on him—in a slow calculative manner. Kevin is still naive, so out of embarrassment, he went to get some popcorn. When he came back, he offered Wren a couple of chunks from the popcorn cup. But instead of popcorn, Wren find Kevin's hard dick coming through his fly piercing through the bottom of the cup and blossoming in a full hard-on out of the cup, yearning for a suck. Don't miss this unique team, they are going to drive you mad with desire as they – did to each other.
