Mystic Wand with 5 different speeds which automatically controls the intensity. Others are humping folded blankets, wooden floors, riding the arm of an overstuffed chair or pressing against hard counter tops. If I'm at work I usually do it during the morning but with no hands as I have learnt to squeeze the correct muscles! During intercourse, the woman or her partner simply adds her preferred kind of clitoral contact. Then I tighten and untighten my thighs until I reach orgasm. These fast tension climaxes are silent and many of us grew up masturbating this way to avoid getting caught by our parents or siblings.
These are my favorite so this is my bias.
Thigh Squeezing Orgasm
During long sessions of kissing and genital fondling, I was the classic Sleeping Beauty. Are you a female, middle-aged empty-nester, who is about to embark on a divorce? If I'm at work I usually do it during the morning but with no hands as I have learnt to squeeze the correct muscles! I totally support this image. It gives the best orgasm! The muscles are engaged similar to an athlete in motion.
