That took a while to get

Not the most common fetish

Someones gonna have to explain it to me then.

Need explanation too...my guess is Shou is using something to do bubble but (by hand gesture) Nazrin is thinking of something else.

I hope it's not a 'cut the cheese' pun..

Jacking off to fart, and i thought i saw everything.

I think it's more like Nazrin saw Shou put her hands near her crouch and air bubbles came out. Then Nazrin did the same thing and felt a new sensation.

I thought she was getting off to Shou's fart smell. Would have been better if thats the case

You're doing it wrong!....

... or right?...
