Request Classic XXX Movie with Christoph Clark

#1
Hi,
I'm looking a movie from the end of the 80's or the beginning of the 90's
I'm pretty sur there is Christopher Clark inside.
The story tolks about 3 friends in a big house on mountain with many snow.
The first scene, a guy fucks with a girl in the bathroom and when they finish, the guy lets the girl for his 2 friends (christopher clark).
Someone knows the title?
Thanks.
