Every Friday morning a hot Lithuanian girl trained around the same time every week I would make sure I was cleaning the main gym as this girl was extremely sexy tall extremely long legs and she wore yoga ‘style shorts that went up her perfectly formed arse , for some reason she always wore full bum panties underneath giving a severe line the that went across are smooth arse cheeks , a bit of a wardrobe malfunction but made her arse even sexier . Could not believe my luck when she came into the cubicle and was the first one on camera. She had obviously tried to finish her workout and had held the need to poop to the last minute as she started releasing hot farts into her shorts as soon as she got into the cubicle , they were obviously airy poop farts as they were coming out in short bursts , she got the top of the yoga shorts and pulled them down I think she meant to pull her knickers down with the sorts in one go but she missed the tight panties and pulled her shorts down over her divine Russian arse farting all the time she was removing her clothes . Finally, after 6 months of admiring her tight knicker line under the shorts I got to see what knickers she wore underneath, these where like a skin coloured super tight sheer pair that the cheeks of her arse where spilling out off, no wonder the lines were so severe. She then desperately pulled them down over her bum just in time as the tip of a turd emerged from what looked like a tight arsehole, she got her bum over the toilet as the turd emerged hissing gas escaped around it .
