My friends and I found ourselves in the middle of a domination class by a Mistress like no other. We were going to be trained to fuck our friends so that they would enjoy pleasure. The Mistress first told us to give the women oral sex to start getting them hot. Since we did it well, she gave us the pleasure of being able to fuck them hard. Each of us did our job very well, we fucked them in different positions like doggy style and missionary. Then we swapped partners and fucked the other friends. At the end, the Mistress told us to cum while they gave us oral sex, and so we did: cum in her mouth, on her tits and on her face.
