Sofi M is convinced that masturbation is healthy for women. She even started writing a whole PhD thesis about it. Being a sex researcher in Berlin means she’s pretty adventurous when it comes to sex. Experimenting with her sexuality is basically part of the program – or at least it should be. Through rigorous experimentation, Sofi found out that she’s really into anal. Playing with her pretty butthole makes her cum so easily. It’s such an intense feeling for the spirited beauty. The sensation ignites every nerve-ending in Sofi’s body with pleasure. The bubbly Ersties girl can’t get enough of it!
