As soon as she starts using her hands to push away, a man needs to kick her clit. The bitch will instinctively move her hands there, leaving her mouth available again. After 2-3 times, they start to understand what’s going on and stop their BS.
Make a star out of her. Next time piss on her and in her mouth. Also fuck her ass to mouth. Fisting is also fun along with shoving toys into her asshole and cunt. Have her suck your cock and balls and make her rim your asshole.
