Snape had kept his growth shielded behind his trousers up until this point. He tore his pants off in a haze and Ginny tucked her small hand within his shorts. With a slight of hand Snape had pulled Ginny on top of him and took her hands in a fist.
Ginny had never gone all the way before, and she definitely had never taken anything inside her. Snape seemed to sense her worry, and he unclasped his hands to pull his short aside. Ginny couldn't help but stare. In all of her wildest fantasies she never would have guessed Professor Snape had a large package, let alone an impressively large one. She nearly burst out laughing at the situation she was in but Snape had covered her mouth once again, and had cleverly placed his hand under her bottom to stroke her insides. She shivered with delight as he began to tickle both her ends, leaving Ginny a gushing, throbbing mess as he pulled out of her.
"Take it in." Snape groaned, his own hand stroking his enlargement, creating a trickle of expulsion from the tip. Instinctively Ginny tipped her hips forward to allow more depth as she kneeled over his groin. Snape had closed his eyes briefly but opened them to watch her take him inside.
There was a sharp pain as his width broke through her, but with his guiding hands massaging the small, pink nub, Ginny had something to divert her attention. She kept him inside a few inches, careful not to tear any other precious tissues, and careful of Snape's ginger movements, which had become more haphazard with each passing second. Ginny slapped his hands away and he laughed, taking his fingers and slipping them gently into her mouth. Ginny tasted them for a short while, and being caught off guard, Snape took the opportunity to roll her over onto her stomach. With a nasty laugh he spread her hips apart and mounted her from behind, turning a deaf ear to her chorus of protests.
