Me and matt where spending some time alone in the house all padded up and I was feeling very gassy that afternoot I have been farting in my new air tight diapers that I bought and thought "hmmm I wonder if these are truly air tight?" so I went to see Matt and asked him to sniff my diaperbutt to see if they are air tight.
However Matt didn't like the idea show he sniffed plenty of butts like butt and diaper butts but smelling gassy butts no way. "P.U! he farted in it! he said in his mind as I was letted out a beefy muffled fart right in front of him he as I taunt him to sniff it, Matt didn't wanna do it but in the back of his mind however that if boss made him do it and said no, it was a red bare bottom tanning without question for disobeying. "Ooooh why does everyone pick on me all the time?!" he thoughtly complained "I hate smelling farty butts it so gross and too smelly and not my thing, but I better do it otherwise he'll call Boss for sure and then I'll get a spanking, well here goes nothing*whimpers*."
So Matt leaned in and put his nose on my diaper butt and started sniffing it, as he did I let out another loud muffled fart in my diaper, Matt squirmed and quivered as the sound of the fart but continued to sniff. Soon after he was finish he can confirmed to me that yes they are air tight and he didn't smell my stinky fart throught my diaper at all, so I gave him a hug and we layed on the couch cuddling.
