"Oh Tina, love that ass of yours, so soft, so puffy, so big... mmm"

Josh almost whispered behind you, his face completely sunk between your butt cheeks, as his hands were fondling your buttocks and thighs, groping and feeling your skin, traveling his fingers all over your calves to the top of your butt, over your leggings and suspenders... things were getting hot...

"Here boy, let me show you a trick i've come up with..."

You told Josh with a smirk as you took a few steps forward, your high heels echoing softly on the wooden floor of the room, and you opened a drawer nearby. You picked up a red bicycle pump with a purple hose connected to it, and looked backwards to him who was drooling already at the sight...

"You haven't seen BIG yet, boy..."

You smiled at him, as you stuffed the hose firmly within your lips and placed your hands on the pump handles. You could see a bulge on Josh's crotch as you pushed down the pump handle and a bubble starting making its was through the hose and into your mouth, making your cheeks and face bulge out softly...

"Oh..."

Josh moaned in awe of what was taking place in front of his eyes, as he slowly witnessed your bum bulging outwards, like it was filling from the inside. Each thrust on the pump making it bigger and bigger, as you looked backed and tried to smile back to him, quite difficult at that point due the size of your cheeks and the strain on your lips, widening your eyes in pleasurable distress as each pump and each bubbled seemed to be traveling from within down your body and being forced into your ass, like a pair of balloons that were getting bigger and bigger...

Josh still kept moaning in awe, fondling his own expanding member now at the sight, as he watched your ass steadily inflating and expanding outwards like two pairs of beach balls at first, shinny and stretchy, rubbery sounds echoing through the room as the sound of the pump kept increasing at your thrusting hands, the size of your cheeks bulging out even further as the widening in your eyes backwards to Josh. In a couple of minutes the amount of air that had been forced into your body was quite much, as your ass was now the size of a weather balloon each buttock, bulging through the leggings and the suspenders like two over inflated blimps, the overall size of your backside almost the height of Josh, as he couldn't control himself and approached you from behind...

"MPHMHPHHH MHPHPHPHPHHHHH!!!!!"

You tried to scream through the hose, as you felt Josh's thick cock being forcefully shoved into your air-leaking butthole, and his arms groping hard on the sides of your now almost 4 feet wide ass...

"Just taking care of the leakage, babe, keep going, you still got a whole room to fill..."

Josh yelled from behind as he started some pumping action of his own, the rubbery sounds and the hissing and balloon stretching, combined with both your moaning sounds, completely filling up the room by now...
