When I was 16 I've got my 'sex education' from a 70 y.o. very chubby widow down the street. She learned me first to be clean always and did amazing wonderful things with her tongue. She also learned me to pleasure her with my tongue on almost every spot on her body, but the special spot between her legs gave her the most strong shivers. I loved to lie on her big, round, soft, warm belly, it couldn't be last long enough.
Nobody noticed I was with her almost every day, I couldn't get enough of her and she never refuses me, on the contrary she seemed to find a lot of pleasure in this herselves. As a young horny and hungry boy I could cum several times on the row, the widow let me and often had joked me for my enthusiasm.
But one day her daughter caught us toeter and then it was over.
I still think back to that time with great pleasure.
