"You do beg so prettily, Potter. Are you crying too? What would your friends think if they could see you now? Begging for my touch like the slut you are?"
Harry groaned and thrust his hips back. "Please!" Harry heard Snape's trousers fall to the floor and then suddenly his underwear was pulled down to his knees, but not removed completely. It meant that Harry wouldn't be able to move as much as he wanted, Snape would control everything. The angle of the thrusts and whether or not Harry ever got to come.
Snape thrust his fingers inside without warning and Harry gasped at the unexpected intrustion. His cock was hard and leaking precome on the front of his underwear and some even seeped out onto the skirt. He screamed when Snape found his prostate and stroked it again and again.
He was almost light-headed with lust when the fingers were remvoed and he felt the sting of Snape's cock on his arse. Snape thrust in roughly, not asking or waiting for Harry's permission. Harry lost himself in the sensation of being pounded from behind and being forced against the wall in front of him. The stone was rough on his aching cock, but it was a good kind of pain and he revelled in it.
Snape's hands were on his hips as he pushed into Harry again and again. Harry's balls drew up and he knew he wouldn't be long in coming. "Sir! Please! I have to - I'm gonna come! Let me come!"
"No!" Snape growled close to his hear. "Not until I say so!"
Harry tried to rein himself in, but when he felt Snape bite on the top of his ear, the extra sensation sent him over the edge. His muscles clenched down on the cock in his arse and his own cock spurted over the wall in front of him, globs and globs of it, some dripping back down towards the floor.
Gasping for breath, his thighs trembling, Harry hung his forehead against the wall as he felt Snape stiffen behind him and his arse filled with warm seed.
Snape slid out of him and turned Harry back round, kissing him roughly. Once they came back up for air, Snape pointed to the wall and the floor. "You know what to do, Potter."
"Yes, sir," replied Harry as he got down on his knees and began to lick the floor and wall clean of his splattered semen.
"And what truth did you not want to reveal to your friends, Harry?" Severus asked him later that night when they were tucked up in bed. Harry snuggled close and felt contentment wash over him, here in his husband's arms.
"They wanted to know what we did in bed," Harry admitted.
"And rather than tell them, you put up with dressing as a girl?"
"It's private, what we do together," said Harry. "I ddn't want to upset you, Master. I know you are a very private man."
"I am, Harry. But I find I wouldn't be averse to you wearing a skirt again."
