They will keep him submitted

Tai's fists start to clench as Asa fucks his cock with her ass.

"Oh uh." Sally says.

"What's wrong?" Asa asks, "Too much?"

"Afraid so but not the way you think. I can see it in his eyes. Our man is about to go into a rage. Happens when you have too much of the drug. Too much testosterone."

"Dangerous?"

"Nah." Sally says taking a bottle out of her purse and spray a liquid on her boobs, "If it was I wouldn't be promoting it."

Sally then smothers Tai with her breasts, letting him smell the chloroform she spray all over them.

"Just keep riding him while I smother him. That should calm him down."

Tai fights hard to stay away while Sally smother him with her tits while Asa fucks him with her ass, but he didn't know how long he could last.
