Modeling naked guy for Biology/Sex Ed class stories

[Disneyprince1783]

Hi all! I’m looking for a specific story, but similar ones will work as well. The story I’m looking for is about a 18 year old guy who is asked/maybe made to model in front of his senior class for either a biology or sex education lesson. At some point the class starts drawing attention specifically to the guys foreskin and the teacher asks who in the class is and isn’t cut, then he offers for the cut guys to come up and retract and learn about the models foreskin. When his bully touches his foreskin he cums on his bully or something? Any erotic story about a guy modeling naked for his (any) college or senior class is great but if any of yall have any stories that harp on about foreskin I would love to read them. I’ll post some similar stories I’ve found but I just can’t find this specific one. If it help I think the guys name is like Danny or Dylan or something.
