Bella Carrera is extremely ticklish, and in this clip she is strapped down and tickled on her upper body. She is really violent when tickled, so next time I will have to strap her feet down so I don't get kicked.
Now that was sexy. But yes, I saw how the body tries to scrunch up and move away from the tickling. Grab them ankles next time, stretch her back out flat and sit on her knees while you go to town on that lovely bare midriff. Oh what music she makes.
