On a quiet street in Argentina, two young friends giggle nervously before inviting each other inside for a 'study session.' But as the door closes behind them, their minds are elsewhere. They're here for the petera, the blowjob, a word whispered between them in hushed tones. One girl, her heart pounding, reaches out to stroke the other's hardening cock through his jeans. He inhales sharply, then pulls her close, their lips crushing together in a hungry kiss. She unzips him, her small hand wrapping around his throbbing shaft, her tongue tentatively licking the pre-cum beading at the tip.
