Professordotadu, a seasoned educator in the art of gay pleasure, takes Cristofh under his wing for an exclusive, uncut tutorial. In the privacy of the bathroom, the professor reveals his massive, veiny cock, already leaking pre-cum. Cristofh, wide-eyed with anticipation, tentatively takes it in his mouth, swirling his tongue around the sensitive head. The professor guides him, teaching him the rhythm and pressure, before bending him over the sink. With one swift thrust, he enters Cristofh, filling him completely. The professor fucks him hard, his heavy balls slapping against Cristofh's ass, as Cristofh grips the sink, his knuckles white, moaning in pleasure and pain.
