Mistress Irene has a legendary ass and this scene opens with her ass engulfing a slaves head who is already kicking for air. Her slave has a tiny little cock and that gives her the urge to want to hurt him. She pulls out a bunch of clothes pins and attaches them to his balls and nipples and then sits full weight on him again. This time she gets creative and starts to apply the clothes pins between his fingers and then some more on his little berries. She shifts and he catches a quick breath so she reminds him to breath when he can because she might get comfortable and forgot about him all together.She orders the slave to touch himself and she turns on a timer to see how long he can go without breathing. At 30 seconds he panics so she lets him breath and then says she needs 40 seconds this time. The slave squirms from lack of air, the pain of the clothes pins, and he strokes himself frantically. He makes it over 40 seconds so she gives him some more air but tells him he needs to do better and wants him to work up to 5 minutes. To help she will have her big fat girlfriend over everyday to work with him until he reaches his goal she tells him. Again she sits down and this time doesn’t look at the time, she just settles in and the slave now seems to be getting more comfortable accepting his place under her ass where he dreams of spending hours every day until the end of time. “Enjoy this perfect ass” she tells him.
