As expected, the other teenager immediately shed his clothes. He whispered, tried to entice Harry, made promises and put on a good show, at least from the Potion Master's point of view, though he could only see the lean boy's back. Despite his earlier admittance that he had no interest in "empty" sexual contacts, Zabini's movements were sinuous, sensual even, an invitation to touch, to take. Harry seemed entirely unimpressed. While the teenager had to be convinced that the young lion was watching him, the Gryffindor only starred at the door, seeking Severus eyes, despite having no chance to see them, since the transparency spell was one-way. When the young incubus was worked up enough, the parsel-mage started to whisper his transfer-spell, and with a shout, the young Slytherin came all over his hands and upper body before breaking down. Within moments, the Head of House entered the room. A quick check proved that Blaise was alright; his magic was just all over the place. His master had crouched down beside him, pulling the boy into his lap, easing him, "It's okay, *little snake*, everything's fine."
