Hi!

Ok, so I randomly remembered this story I read a while back and I've been wanting to re-visit it.

What I remember:

This guy walks in on his nephew with the girl. Older guy tells his nephew to get dressed so he can go to school.
'Later on in the story, the uncle collapses, and when he comes to, his nephew tells him the reason he collapse was because he's been holding in his urges and all he needs to do is jerk off. The uncle is appalled at the idea, considering it "dirty". Of course the next scene you have the nephew "helping" his uncle jerk off.

Any ideas what story this is?

Thanks!
