Koiito Kinenbi 2

A girl named Aisha who is Santa's daughter is just finishing up delivering presents. At the last house, she trips on the snow on the porch and gets knocked out when she hits her head. The perverted boy living there finds her, thinks that she is his Christmas present, and proceeds to first grope her breasts and then fuck her. She wakes up while he is inside of her much to her surprise. It actually turns out that she was supposed to be the guy's Christmas present and become his girlfriend.

The second scene of this is my favorite scene. Aisha's younger sister, Sasha, comes to visit and tell Aisha that their mother wants her to give her some grandchildren. If she doesn't want to, Sasha can do it instead.
