Cock Sucking Training by Mistress Mercy

Description: As this scene opens mistress mercy is stuffing her big black cock down her slaves throat and calling him nasty names. she moves up to the bench and sits on his face and asks if he likes her cock or ass better? hard to say what he is saying from under her ass but that doesn't stop her from calling him a nasty cocksucker. she wiggles her gorgeous fleshy ass on his face and when she sits up to let him breathe she asks him again and he replies "your ass, goddess." she moves back over his head and says "in that case you are getting my cock." on her haunches she again stuffs the big thick cock down his throat. she face fucks him and says "why should i give you what you want?" she moves forward to again sit on his face and tells him she is training him to get used to taking and swallowing any big cock she sticks in his face. "you'll be able to take them without gagging, all the way down your throat" she tells him. she sits full weight until he starts to kick. she gives him a short breath and then sits down again. she tells him if he kicks for air it must mean he wants cock. when he starts to trash again she slides back and again gives him more cock. when she gets on his face again she extends her legs across his body until the slave eventually gets desperate again. that means more cock and as he slobbers all over it mercy asks him if he is sucking it the way all the men taught him to. this time she really fucks his face, trying to get it all the way down his throat. she then stands on the ground and face sits him in a forward position. she looks at you and says you should be there sucking her cock while the other slave suffers under her ass. she compares the slaves little cock to her big unit and slaps it and laughs at how little and flaccid it is. when he needs to breathe again, the cock is back in his mouth. she rotates between her ass and her cock and tells him she is going to use the cock on his ass soon. slut training means taking the cock in both holes.
