Himself, by accident

As Harry sat with the manual sounding out the words for the compulsion spell, trying to make sure he could use it properly on someone later, Harry never saw the dull flash from the inside of the cabinet.

Feeling himself start to harden in his boxers, Harry stifled a moan as he imagined watching a witch using the toys on herself. Pressing his hand to his throbbing erection he pulled down his trousers, stepping out of them to stop from falling over them and kicking them to the side where the vanished beneath one of the racks of clothes.

Palming his erection, Harry quickly started wanking to the images in his brain of various witches he knew fucking themselves with a toy or blowing a dildo. Yet despite feeling hornier than he had in his life, Harry grumbled under his breath when he didn't feel any closer to cumming than when he started.

Under the curse on the armoire, not that he knew he was under it, as well as the compulsion of the toys, Harry wouldn't be able to cum without using at least one of the sex toys. With both acting on him, his hand reached out and picked up the first toy in reach.
