Potter's grip was surprisingly strong; Snape doubted he'd be able to break it without causing one or both of them serious harm. His cheek felt cold where it pressed against the stone wall of the Slytherin common room.
"How do you like it?" Potter's voice was guttural.
"Damn, you, Potter," he replied, gasping as Potter leaned harder against him.
He could feel fingers at his hole. Potter was pushing something inside him. No - somethings. They felt smooth and cool, and he felt his arse swallow each one. Snape grabbed his cock and began to pull, frantic. Teeth bit down on his shoulder and he came.
Oh, fucking God. The - things - in his arse were being pulled out, one by one, his prick shooting helplessly as each popped from his reluctant, clenching hole. He groaned with pleasure, Potter's breath hot against his ear.
