Sabina is a sexologist and the inventor of a new kind of dildo designed to hit the G-Spot. So she knows a lot about fucking. She expanded her education further with this trip to our studio to fuck for the Voluptuous camera. "The guy I fucked had a good-sized cock and when he was fully hard, it curved up a bit, rubbing up against the right spots. A good sex researcher never stops learning so I need to do much more studying in the future. Maybe I'll devote more time to tit-fucking. That seems to be ignored by the well-known sex science laboratories." Good idea!
