[Kanrodou Art (Kanrodou)] Cattled and Machine Fucked by Aliens [Full Color]

A woman's daily morning jog ends mid-stride when her body freezes and she floats helplessly into an alien laboratory, where her captors promise safe passage home in exchange for full cooperation with their research. Stripped and restrained, she endures hormone injections that swell her chest into huge, leaking udders, mechanical milking devices latched onto her nipples, and a cold steel piston driving into her as her body betrays her with climax after climax. When the experiments conclude, the aliens renege on their deal—instead of Earth, she's enrolled in a lifelong interspecies breeding program, and judging by her breathless, heart-marked moans amid writhing tentacles, she isn't exactly complaining.
