[Inaba COZY] Iinari Chapter 5 Human Race Reproduction Plan

Tia and Hyperion are the last survivors on the space colony Titan after a mysterious pathogen wipes out humanity, forced to enact the Human Race Reproduction Plan with an artificial womb fixed by nanomachines deep inside Tia's anal passage. What begins as clinical documentation — the slender, glasses-wearing Tia clinging to his clipboard after 168 hours of fixation — dissolves into fevered anal intercourse where probing fingers, leaking cocks and shuddering thighs blur procedure into pleasure as he learns humans crave reproduction because sex is pleasurable. With debates over natural versus artificial insemination abandoned for deep, thrusting creampies and a desperate vow to become the new Adam and Eve, the two males surrender to cumming deep inside to make each other pregnant and restore the human race.
