In grade 10 I once left my math text book in the change room. Math was right after PE. The math teacher let me go back and get my book. When I walked in there was no PE class so the change room was empty except two teachers who were both naked. Both were quite hot. One was average but the other was BIG at least to me who was small. I'm not sure who was most shocked and embarrassed, them or me. I just grabbed my book and left real fast and fantasized about it for years.
