Snape gave her a moment to look around before leaning down to speak softly. "This room is also free of penetrative sex... You’ll actually find that only one room allows full intercourse, though others are more permissive with what can be used for the penetration aside from one’s own genitalia." Hermione furrowed her brow, still wishing she knew how many rooms there were, but knew better than to voice the question when he’d instructed her not to speak. He chuckled, clearly aware of her frustration at an unanswered question and he squeezed her hand before letting go and stroking his fingers along the bare skin of her upper back, lifting goosebumps in their wake.
