Probie79's sissy training school welcomes a bi-curious student eager to explore cock worship. The trainee is first presented with an intimidatingly large dildo, which they must worship with their mouth and tongue. The trainee's enthusiasm grows as they take the dildo deeper, learning to please it as they would a real cock. The scene intensifies when a male trainer joins, offering his throbbing member for the trainee's oral skills. The sissy eagerly sucks and licks, practicing the art of cock worship under Probie's expert guidance, resulting in a hot, explicit session that leaves both trainer and trainee satisfied.
