Imagine allowing bonbi to tie you down to her bed. When she's satisfied that you can't move a muscle she stands over you and moves over your head. You notice she's not wearing any panties under her skirt as droplets of grool drip on your face. She giggles and collapses onto your face, her wet lips contacting yours. She grinds for a bit letting out soft moans until she suddenly stops, adjust her skirt so your head is fully enclosed under it and lets out the longest, deadliest fart you've ever experienced. She's giggling like a lunatic now and through her hysterics manages to squeeze out "you...you know anon, my parents call me the walking gas chamber haha"
