[Ryuuta] Contact (COMIC ExE 25) [CHLOEVEIL]

A twin brother's offhand suggestion of wife-swapping has curdled into a consuming secret: one man slips into his sister-in-law Masumi's bed wearing her husband's face, hooked on the thrill of the pretense while both wives remain none the wiser. On a couples' trip, hesitation melts in a steamy car encounter—she confesses she understands why he couldn't stop and pulls him into a deep kiss—before their trysts turn utterly shameless, her voluptuous body riding him hard as she teases that they're a married couple right now. Every stolen night deepens the lie, leaving both marriages balanced on the edge of discovery.
