Honestly it would be just as easy to sneak off and pull a quickie rather than grind. Seems like a tease to me, because most girls wouldn't just run off with random guys for a quickie. At least at my school.
I don't go to school dances anyway. Nobody ever asks me to Tolo (or as I call it Trolo), and i'm too much of a pusillanimous individual to ask someone, but I do plan on asking someone next year to homecoming. That's the next opportunity at least. Dances seem a little overrated to me though, which makes it not that big a deal.
Yeah, they're not really anything special.
And tbh, the main part about grinding in my experience is basically a softcore foreplay. Get a guys richard hard during the dance, make him super horny, then after the dance, at the after party continue to tease, and then when you leave go forget.
The general schedule for school dances for my group of friends is this;
Take pictures
Go to dinner
Go to dance
Go to afterparty
Go to indiana dunes next morning, stay all day and camp over night there and let whatever happens, happen.
Go back home next day.
Its a ton of fun actually, the dunes are awesome :3
