It doesn’t make sense to me that she’d be commenting on his foreskin when it’s not even over the glans and she’s just jerking him like she might a loosely-circumcised cock.
The audio is pretty crappy and it’s not clear enough to be sure but I think that she says “Your fucking wiener’s scared”.
This would be continuing the joke where just before she says: Oh, no. What’s going to happen to you?
He says: I don’t know.
She says: Ohhh.
He says: I’m scared.
