Despite his moans during the moment of his hole tonguing and scretching, your rim/fist/fuck apparently wasn’t that great.

He has a partner and doesn’t want to share.

He has a partner and knows his balls will be sliced off if he discovers he was fucking around with you.

His mommie never taught him how to say thank you to strangers.

He has mild autism and lacks social skills.

He thinks a good rim/fist/fuck job is his God given unalienable right.

Or:

Coming from a South Floridian, his brain is just plain FFF’d – Florida Fuck Fried.
