Tickle Ghost
When you nut all over her and it starts to slowly slide down her sides causing her to react.
Last night I gave my step sister tickle ghosts and she wouldn't stop squirming.
ghost tickles
When you're cuddling and someone lightly and slowly grazes your skin or the hairs of your skin with their fingertips and it makes you get goosebumps because it feels niiice. Usually best with one who is good with his or her hands.
We were cuddling and he gave me ghost tickles - it was so erotic.
