'Good Girls Only Cum on Cock'

He'd edge her like this for ages, whispering little suggestions, dirty ideas, making her expand on them, getting her ready, ready for his cock. Because as soon as he slid in her wet little cunt, that was it, it was all she was allowed. No more play, no more tit play. Just fucking, what she was made for.

'The only way good girls cum is from cock in their pussies' he'd make her say over and over as he edged her.

The only thing was, she couldn't, it felt so unbelievably good, but it was never enough to take her over. No matter how long he fucked her, no matter how hard, and sometimes it was unbelievably hard, she was just on the edge the whole time. She was losing her mind on his cock.

She offered him anything. Her cunt, her arse, her mouth. He took them all, but it didn't change the fact good girls only came on cock. He'd fuck her, every night, edge her for hours from the inside. She offered even more. Her dignity, her freedom, even her friends. He took those too. It didn't help, they all came on his cock. The fact she couldn't made them all laugh, tease her, and take advantage of her delirious horniness. 

Of course, she'd completely missed the fact it wasn't her cunt that was broken, it was her mind. The very first time they'd done this, as he'd whispered over and over that she could only cum with permission, it had rewired her. Just the way he hoped.

She could have cum the second he told her to, he simply... didn't. 

She was better like this. 

Good girls only cum on cock.

The best girls can only cum with permission.
