This is very tongue in cheek with lots of comic moments. One character has sex with a girl he has just met, she laughs at his come face and he is embarrassed about coming too quickly.
When they have sex a second time she does come, but she’s not a girl, she’s an 82 year old woman who was also caught in the shower which made her young. It doesn’t last very long, basically she turns back at the point of orgasm, only to be told that she had a lot of gall for attacking his come face.
He is not happy especially when the mind reader lets everyone know he’s a granny shagger.
