Made to swallow. SeXStoRY

This is my fantasy, With my hand tied together behind my back I am knelt down on the floor with my back to a bed. This guy stands in front of me with his hips at my head hight and he informs me that, "You are going to suck my cock and you can't go until you have swallowed all of my hot sticky cum". He then removes his jeans to reveal skin tight speedos. I can see the shape of his cock and can see its beginning to get hard. He waits then slowly moves forward, his cock now right in front of my face. He holds my head with both hands and pulls my face to his cock. I feel it growing harder under the speedos wanting to break out. He pulls out his cock and says, "open your mouth". I do and without warning he thrusts into my face. I begin to suck and he moves my head backward and forward."Suck Harder,HARDER"! he says. Faster, deeper and harder he scull fucks me." My cock loves your mouth" he says. He continues to fuck my face for what seems like hours, stopping now and then to savour me sucking hard on his pre cum dribbling cock until he can't hold it in any more. "I'm CUMMING......AHGHGHHH".... He pulls out slightly then with both hand around head he pushes deep into my mouth.His cum rushes and pulsates into my mouth, more and more. A weeks worth of cum fills my mouth. "NOW SWALLOW"!He says.
