I go up to men sitting in Japanese restaurants and rub my pussy on the back of their heads when I get that urge.
I've never sexually assaulted a piece of furniture or a pillow. Never occurred to me to try. There's always been better options, like my hand.
Washing machine. I've met two women who admitted they have used that device as a ad hoc Sybian.
My motor cycle. Was giving lessons & the woman in front of me had a mini orgasm from the motor vibes. The look on her face when she stopped and stepped off the machine... Had a number of others who really enjoyed the sensation riding behind me on the P Pad. A few added further stimulation by rubbing their breasts against my back.
BTW, I hope this is asked of the guys, as it is not just women who find new uses for household items, or bikes.
Once or twice when lusty guys were watching. a sofa arm, a desk.
