Yesterday, a man repositioned my legs between his, with a gentle "There… better…"
A few seconds later, he fell into my lap.
And, despite all the naughty images your mind could have called upon just right now, there was nothing even remotely sexual in the whole event XD
That was actually the result of being packed like sardines in an overcrowded bus. I got a seat, he didn't. And it turned out my knees kept his legs from settling into a comfortable standing position, so we had to rearrange that a bit. A few seconds later, the bus jolted forward and he forgot to brace himself. End of explanation.
Heck, he wasn't even remotely attractive... ;-)
