"Do you like your surprise?" Kirsty asked. I grinned back, we fetched some water from the bathroom, swallowed our respective pills, and headed back to the bar for dinner.

All the tables were set for two, and most of the other guests were already seated when we were shown to our table. Kirsty loves her food and we were treated to a delightful three-course meal. Anna the barmaid was waiting on our table and there was plenty to choose from on the menu; I had pate on toast for starters, a steak and ale pie as a main and a vanilla panna cotta for desert. It was all delicious, and very filling. Normally Kirsty would be completely uninterested in sex on a full stomach, so I was a little worried that I would be disappointed this evening.

As I finished my last mouthful I looked up at Kirsty. I hadn't noticed any physical difference in her yet, and was feeling a bit bloated from the meal myself. I glanced down at Kirsty's breasts and back up at her. She looked down too, cupped a breast and said, "Nothing yet." She then looked furtively around at the other diners. I also looked at the couple nearest us; the woman's tits were definitely bigger than they had been when we sat down, and I could see an impressive tent forming in the man's trousers. Licking his lips, he stood up, bent slightly and farted before taking the woman's hand. She also stood, her eyes fixed upon the tent in his trousers. She let go of his hand and cupped his arse cheek as they made their way out of the bar.

Looking back at Kirsty I could see she had been watching them too. She had a slightly disgusted look on her face.

"Did he just fart in the middle of the restaurant?" she said. But then the look on her face turned to one of surprise. My eyes were drawn to her cleavage - her dress was getting visibly tighter and I was sure her boobs were bigger than I'd ever seen them before. But that didn't seem to be what had caught Kirsty's attention. "I need to..." she said, but finished her sentence by lifting a butt cheek and emitting a loud, sustained fart from her perfect little arse. The noise drew some looks from couples on other tables, but there was not tutting or looks of disgust - instead there were smiles and nods of approval.

Kirsty still looked a little embarrassed though, and she glanced down at her bust. Her tits were now at least three times their normal size and her dress was struggling to contain them. I could feel my dick stirring as I gazed at my wife's huge orbs, but then I felt my stomach stirring a little too.

At that moment, Anna arrived to take our dirty plates away. She glanced at Kirsty's tits and smiled at us both. I really needed to fart but was trying to hold it in - I didn't want to embarrass myself in front of Anna.

"Would you like coffee or tea," offered Anna, "or will you be heading back to your room now?" The knowing smile on her face coupled with Kirsty's huge and growing tits led to an increasing pressure in my pants. This was no ordinary erection; involuntarily I looked down at the tent in my trousers and I wasn't able to concentrate on keeping my digestive system under control any more. My fart seemed to last for ten seconds or more and the release of pressure was such a welcome relief.

"I think we'll go to our room now" Kirsty finally answered, and she stood, eyeing me lustfully.

"Yes, yes" was all I could think of to say, and Anna replied with "Very good, we'll see you later then."

I didn't so much walk as stagger down the corridor to our room - the huge erection in my pants making normal walking difficult. Halfway there, Kirsty stopped, leaned against the wall, held her breath and let out another enormous fart. She turned to me and giggled, then continued to our room.
