Cooking class. I blame the instructor for his use of words when demonstrating knife skills and choice meats. In my head, I was thinking of a different tool and different meat and clamped my legs together tightly to push my jeans' seam against my clit. Hopefully I was discreet when I ground my hips to rub my clit against my jeans till I came. I pretended to be stretching and arched my back to ride out my orgasm.
Climbing a lot of stairs during a school field trip. My skirt pocket was deep enough so that when I take a step up, I can reach and poke my clit without having to make obvious efforts to rub myself. I didn't get to cum then, but knowing I could do that in public made me wetter and hornier. Made a beeline to the first restroom I could find to 'properly' finish off.
Haven't done anything of the sort lately though.
Up an Oak Tree, deep in a forest glade.
In the world's harsh wear and tear many a very sincere attachment is slowly obliterated.
Είμαι ταξιδιώτης τόσο στο χρόνο όσο και στο διάστημα
Umm... I don't know... The foot of the bed? :P
