Jeff, curious at his new equipment, fingered his rubber nozzle. He actually shivered from the pleasure of his finger on the rubber.
Amused, and perhaps aroused, Jeff left his room to fetch something, coming back a few minutes later with a pair of pumps, one electric and one a push pump, but both were air pumps with tubes.
Humming he looked to decide which one to try first, before settling on the push pump. Holding the hose in one hand he lowered his free hand to his nozzle and took a deep breath... before popping it open.
There was a rush of pleasure as he felt air trying to escape his hole, but he quickly shoved the hose into his nozzle, moaning and curling his toes as he felt the pleasure of the hose inside his nozzle. It wasn’t very deep but it felt extremely good.
After a moment he grew used to the pleasure, and proceeded to grab the hand pump, before gently making a single pump. He shivered as air rushed into him from that one pumping motion. And with a gulp he braced himself against a wall and started pumping.
The pleasure made him moan and curl his toes with each successive pump, air flowing into him freely as he blushed in pleasure. His taut stomach was starting to bulge a bit from the air being forced into him, evidence that he was being inflated, if only slightly by the pumping he was doing. However his toes were also a point of interest.
Looking past his belly he saw his curled toes, and in confusion noticed they seemed to be rather close together, if anything they seemed to have shrunken a bit. He could feel them just fine, he just couldn’t move them from their curled position.
Deciding not to worry about it, Jeff inspected the rest of his naked form, his belly and, pleasurably, his chest, the only places seeming to start inflating. Namely his chest was starting to puff out beneath his nipples. The beginnings of boobs if he had to guess, which was amusing.
He let go of the hand pump and hummed in wonder... should he switch pumps, keep pumping, or see what would happen if he deflated himself a bit.
