The yoga teacher sucks my cock in the middle of class.

Today i am finally going to give my first yoga class. they say it relaxes a lot and some friends of mine recommended this teacher to me. they say it is the best. when i enter the class i find that we are only two students. the class is boring until the yoga teacher walks up to me and starts rubbing my cock. i can't stop thinking about what can happen if the other boy sees him. the class improves even more when the teacher pulls out my cock as stiff as a stick and while he grips my balls tightly he begins to suck my stiff cock while covering my mouth with his hand.
