I had a guy that liked to have his head bitten really hard while I was blowing him. Frfr it was so weird and I was worried I’d break the skin but he just kept telling me to bite down harder so I just kept doing it until he finally erupted all over my face lol I blocked him afterwards though even though he was hung and fun to serve. But I just can’t get down with that stuff again lol especially since he never told me about it until he was in my mouth and told me to bite it
