Me giving him oral sex.

Carefully, he introduces his big cock inside the ring gag.

It fulfills my mouth and I can't avoid tasting some of the precum for my disgust.

I try to go back for geting myself free, but he presses my face against his crotch.

I keep trying but he's too strong.

"Better be a good slutty boy and use your tongue on it.... or the next thing entering your mouth may be your own cock".

Reluctantly, I start licking the shaft wondering what I should do for him not being angry... But then I notice in fact I do know, I do know what I should do with his cock for pleasing it properly.
