Vaginal Sex

"... Get ready for some good old fashion, dick-to-pussy sex!" He finished exuberantly, smiling down at his best-friend-turned-unwitting-sex-****.

Hermione's ever-present smile stayed on her lips, despite the cum coating them, as she took off what remained of her clothes and put herself onto her back, baring her vagina to him. Harry took a second to admire the view, having never actually seen female genitalia beyond the magazines he'd caught Dudley looking at, or occasionally Seamus and Dean. Why they were always together when he caught them was not a question he really wanted an answer to.

Harry shook his head, clearing the childlike excitement from the imminent prospect of having sex for the first time and approached rapidly. Once he was within reach, he began rubbing his dick along her slit, feeling a surprising amount of wetness for a girl who was supposed to be under a spell.

'It DID say that it was supposed to make her act like everything I say is completely reasonable... So maybe this has actually made her a slut?' Harry thought to himself, before a darker portion of his subconscious surfaced. 'Or maybe she always was a horny little slut, aching for cock?'

Harry shrugged. 'Who the hell cares?' He thought to himself, finally driving his dick into her wet hole and beginning to pound. She was absurdly tight, the velvet walls of her vagina seeming to grab at his dick every time he drew back and slammed it back into her. Her moans grew louder and louder until she was practically shrieking, as he slammed into her over and over, her tits wobbling as she panted and writhed under him.

Deciding he wanted a change of pace, he flipped her over onto her hands and knees and drew back, slapping her ass sharply for good measure. After her moans intensified dramatically following the first slap, Harry gained an intrigued look on his face and continued to alternate between spanking her large, rippling ass and her breasts as they hung down, while the other hand gripped her hair firmly and pulled her head back as he pumped harder and harder into her depths.

Harry could feel his orgasm beginning to build, but he wasn't sure if this was how he wanted to finish, regardless of how satisfying it was.
