"You want to go into my asscrack!" Yuriko said giggling as she lifted her skirt, showing you her striped panties. She then pulls open the back of her panties with one hand and drops you inside her fantastic backside with the other one. "You love it, huh?" She says giggling as she shakes her butt with you stuck to it. She then sat down on a pillow and bounced up and down again, wedging you deeper into her rump.

And without previous advice, Yuriko broke wind loudly. PRRRRFTT!

"Aaah, that one felt great! Maybe not so much down there, but I bet you enjoyed it anyway, huh? I know you love my ass soooo much!" She then proceeded to wiggle her butt some more as a storm of farts unraveled. FRRRP! BRRRAP! PUUUUU! FSSSSHHH... "Aw, a silent one!", she pouted.

The room now stunk of her gas, and inside her panties, it was naturally much worse. You could barely stay awake now.

"Well, naughty boy, I think I want to play with you some more..."
