This time started innocently enough as well, but my innate horniness and frustration eventually came to the fore and what can only be described as gro...ming began to take place after the teasing of the previous weeks, though nothing overt initially.I’ve written this as I remember it, as almost the first thing I did was delete it off my phone afterwards. I couldn’t be too careful as to who might see it and draw the ‘right’ conclusions. Yes, I’ve corrected the grammar and spelling as well as it.

"Can I feel you?" Without waiting for an answer, I put my hand on her bare thigh. Her legs were close together but, even so, her knees were about three inches apart, unable to close completely because her thighs were so large. Some guys like slender legs but.
