H x Alien

He was on his way to meet his girlfriend, made a detour for milk, and got scooped up by aliens instead. Now he's slated to be frozen and used as the test case for a ray gun aimed at the entire planet.

The abduction plan is straightforward enough on the aliens' end: freeze the human, aim the G-Ray, sterilize the planet. What they didn't count on is one guy talking, teasing, and eventually sleeping his way out of becoming an ice cube, using the only leverage he's got against a curious, big-built monster girl who clearly wasn't briefed on human anatomy.

You click through the scenes as this reluctant abductee, working the alien captor's curiosity into something more personal one exchange at a time. It's built as a straight visual novel, and right now it only covers a single zone of the ship, so there isn't much ground to cover yet.
