Mesu neko: Kubire koshi 2003

Directed by Yutaka Ikejima

A man enjoys a picture-perfect family life, but while having sex with his wife, he sees a strange light outside and wanders out, as if drawn by a spell. A semi-nude alien woman is there, beckoning him. Taken aboard a UFO and engaging in a whirlwind of extraterrestrial sexual encounters, the man gradually loses his grip on reality..
