Бойфренда наказали пердежом

I come back home and go into our bedroom to find my boyfriend masturbating all by himself to porn. I get really upset to see that even though he is lucky to have such a hot, good looking girlfriend like I am, he still jerks off to porn movies. So I decide to punish him, to teach him a lesson. I start giving him jerk off instructions and tell him to watch me. Little did he know that I was going to start farting in my panties and tease him with my ass while asking him to continue jerking off. I guess a relationship with no surprises would be a boring one after all, right? I wonder if he's gonna be able to make it till the end of my reverse countdown, or he'll end up cumming before and get punished even more.
