Brad's stepdad begins to shift and relax, grinding Brad under his huge posterior, rubbing his huge butt all over Brad.
"STOP!!" Brad yells in humiliation, but his stepfather, Steve, doesn't appear to have even heard him
He continues to rub his butt until he is perfectly comfortable.
Steve then yawns in relaxation, putting his arms high into the air and, as a result, butting more stress on Brad's body.
The smell starts to get to Brad, it smells like plenty of sweat and ass. He decides to think up a way out, but finds escape futile. Steve then leans to the other side, giving Brad hope of escape, but lets out a massive, loud fart all over Brad.
PPHAAAAARRRRRPPPP
The smell is so powerful that Brad can't even move out of the way in time for Steve to lower his leg and sit back on Brad. Now, Brad is trapped with the awful scent.
Steve sighs loudly in relief, then begins to shift into comforting position again, grinding the stink of his powerful flatulance into Brad. After much rubbing, Brad ends up facing upward, laying flat under his stepdad's huge buttocks.
Steve then leans forward, this time giving Brad no hope for escape, and farts even louder
PPPHHHHHHHHHHRRRRRRRRRRRRRRPPPPPSSSS
Brad can't even cover his nose as his arms were flat and out under his Stepfather's, huge, firm buttcheeks. He tries to hold his breath, but the capacity of his lungs just isn't enouph. He ends up taking in a large amount of Steve's fart. Breathing heavily, he cannot hold his breath anymore, and ends up taking a full blast of Steve's farts again.
Steve begins to grind his ass on Brad even more, then...
