Paleontology (2015)

Paleontology (AKA Paläontologie) is a Swiss short film made in 2015 by director Pablo Callisaya. A couple of college students are tired of student sex and decide to set out to seduce mature women. One of them meets a friend of his mother (Charlotte Heinimann) and ends up sleeping with her.
The sultry Charlotte Heinimann gives us a beautiful sex scene. The guy is underneath and she passionately rides him, asking him to come inside her.
