Scientists proved this exercise really helps (get fucked)

A woman in a light blue top and beige shorts stretches on a yoga mat before engaging in explicit sex with a man. She performs oral sex on him, then they have intercourse in multiple positions including missionary and cowgirl. The man ejaculates on her chest while she lies on the mat, and they continue with her riding him and taking him from behind. The setting is a bright, modern room with a TV and wooden floor.
