Moon Mission - part 1 (Patreon)

The compression mesh of the inner suit was supposed to feel like a second skin, but right now it was digging into his thighs. Kevin shifted his weight against the bulkhead. He'd been lingering near the forward hatch while Gemma ran the diagnostic on the carbon scrubbers, not really paying attention, just waiting for the green light. Then the fabric pinched higher up. A deep, heavy pull started at the base of his spine, spreading outward. He looked down, thinking the suit's internal cooling garment had bunched up.

It hadn't. The thick grey material was stretching tight across his upper legs. Too tight. His quads felt softer, heavier, rubbing together in the center where there used to be a gap. The suit was cutting into flesh that hadn't been there when he strapped in at Cape Canaveral. His pelvis felt wider, the heavy seams of the crotch panel pulled awkwardly flat. He grabbed at his own hip, his fingers slipping off a new, sudden curve.

"You seeing this telemetry?" Drake asked from across the module, tapping at his tablet.

Kevin couldn't answer. He just stared at his own legs. The Orion suit was tailored for his male frame, narrow in the hips, but the fabric was currently straining across a distinctly feminine lower half. His pulse hammered in his ears, loud enough to drown out the ambient hum of the cabin fans. He tried to adjust his stance, and the foreign weight of his own glutes shifted against the suit's rigid lining. It felt entirely wrong. He stood there, mouth hanging open, hoping neither of them turned around.
