On the walk back to the hotel, Snape teased her periodically using both the spell he’d used before and his own hands. As they passed a dark alcove, he suddenly pulled her inside and cast a silent distraction spell for any muggles before having her bend over with her hands against the wall. As she moved into position, she felt him dragging the skirt of the dress up to her waist, leaving her bare from the arse down. Expecting him to finger or perhaps spank her, she was astonished when she felt the blunt tip of his erection pressing against her. She hadn’t even noticed him freeing it from his clothes while she got into place, but she moaned in pleasure as he slid in all the way to the hilt.
