She’d obsessed about having larger breasts ever since her’s stopped growing at just an A cup. She’d thought seducing the plastic surgeon would give her everything she wanted, but it wasn’t the first time he’d had someone try this on him. She woke from the surgery, and cried out when she saw her chest wasn’t any larger than before.
‘Oh, I’ve given you something very special,’ the surgeon told her. ‘They can be any size you like, you just have to pump them up. I’ll show you how it works once it’s all had a while to heal, okay?’ What a dream come true, breasts any size she wanted, She couldn’t wait!
Finally the day came, she was so curious how it would work, she couldn’t figure out where on earth they’d be pumped from. Even when he handed her the 10 inch dildo, she didn’t get it.
‘Slide it in,’ he encouraged her, ‘see for yourself.’
The dildo was so thick and long, it took some time and lube to even work it inside her. He told her it had to be deep, really deep, clearly aroused as he watched. She wasn’t sure if he was just teasing her, until as the dildo went as deep as she’d ever known, she felt it, something, in her chest. He hadn’t been joking.
She did it again, and again, little but little she felt the skin tightening, and with thrust after thrust sure enough, her breasts began to gently swell.
‘Oh my god, it works, it works!’ she cried, fucking harder, watching them ever so slowly get bigger. It was a like a dream come true. She fucked harder and faster, but still their growth was so slow. He explained, with a smile, if it was any faster she might damage her skin, it was for her own protection it took so long.
Still, even the little growth she saw had her so excited and aroused. She’d been fucking so hard and so long that the inevitable happened, she began to get closer and closer to the edge, and with a cry of pleasure, orgasmed all over the dildo.
But her cry turned to dismay, as she watched her breasts deflate back down to their original size within seconds.
‘Ah yes, I should have said. Obviously we needed to have a safety valve as we didn’t want them to be over inflated and be damaged or damage you. Unfortunately any kind of sexual climax seems to trigger the release valve too.
‘But, what? You mean I can’t cum, at all?’
‘Of course you can cum, sweetie, just you’ll lose your cleavage if you do. But you can always pump them back up.’
‘But, it takes hours, every time. Hours and hours of fucking myself and if I cum it’s all a waste!’ she exclaimed.
‘Yes, that’s right. I’m sure you’ll manage,’ he said, barely concealing his delight. ‘Oh and the other thing, being experimental and all, I’m afraid they seem to slowly deflate over time. Just a few cup sizes a day. But you’ll need to top up, every morning, and afternoon, and evening. Just don’t cum, and you’ll be fine.’
‘Oh my god, you bastard! You did this on purpose, you fucking bastard! I’m going to be horny all the time, you know how I get when I’m horny!’
‘I do indeed,’ he said, undoing his trousers, his long cock flopping out. ‘Now guess what else pumps you up?
