He feels SOOOO bad about it too :( Like in the moment when he's listening it IS a normal platonic thing. But then he's got his hand on his dick and his brain goes "well remember when Buck told you about the first time he got pegged and how he couldn't stop moaning so the girl stuffed her fingers in his mouth? now picture it's your dick in his ass and your fingers in his mouth" and he comes harder than he has in his life.
