chapter 5

After they had been dating a few months, Mark started to stress about the secret he was keeping. Should he have told her by now that he knew about her kink? Should she know that they had chatted online in the past? But Mark got a sense that if he were to confront Tammy about her gaining now, Tammy would do what she always did - bottle it and start to lose weight again. He began to think that if he wanted to keep Tammy growing, he'd have to keep her thinking her gain was natural; the normal relationship weight gain all men and women experienced at some point in their lives. And so, Mark kept doing what he was doing, overfeeding, over-sexing and massively over-pampering the now chubby girl to her heart's content. Above all, Tammy needed the space and time to become that fat piggy girl that she always wanted to be.

It was incredibly cute watching Tammy fatten up. Mark saw as Tammy's ass swelled up more and increased its width, popping out conspicuously behind her as she walked. When she strutted around naked, he saw the fat ripple and bounce, which he knew Tammy would be feeling too. How could she not? He could only imagine how turned on it must be making her.

In truth, Mark couldn't believe how easy it was. Tammy's constant yo-yo dieting in the past had left her body defenceless against the surge of calories that were handed to her each day by Mark. Before long, Tammy was larger than she had ever been in the past, making all of her 'fat' clothes redundant. Tammy was looking chunky with a curve to her overfed stomach, her arms thickened and her breasts bloomed. Tammy was a fun girl to be around anyway, but as her clothes started to look stretched and misshapen on her tubbier frame, Mark found himself constantly aroused. Tammy's sexy panties were looking incredibly tight as she tried to squeeze her new soft, chubby butt into the same size she always wore. Mark rarely had to initiate sex, but once aroused by the sight of Tammy's tight clothes, his underwear were off and the pair of them were going at it like rabbits.

Mark was careful never to mention the weight gain to Tammy. He never talked about 'fat', but was always sure to mention how sexy, feminine and curvy she was looking. He had no intention of frightening Tammy off, considering how much she had flip-flopped about gaining in the past. Instead, Mark gradually upped Tammy's portion sizes and was always sure to reward her sexually after an especially big meal; not that Tammy seemed to realise that correlation; she'd just lay her head back into the soft pillow and spread her thicker legs wide apart, whilst Mark's mouth worked away under her overfed, bloated tummy.

'Woah! You sure your boyfriend's not a feeder?' posted a guy online after Tammy had posed in a tight sports bra for a photo. Her chubby arms and rolls of flab were on display as the tight material cut in to her enlarged physique. Better still, it was the exact sports bra Tammy had worn the first time she had met Mark at the gym all those months ago.

'No, he's not,' Tammy replied simply. Did she really have no clue?
