Grandma walked in and didn't stop
I was watching porn on my computer. Milf porn. Im in another zone and just doing my thing. i'm 20 so I'm always busting a nut all day LOL. Anyway my back is to the room so Idk if anyone walks by or in. my grandma lives in the downstairs apartment. I'm doing my thing and after I orgasmed i turned around and was shocked when I saw her watching from the hall way. I instantly said sorry but she told me not to worry about it. she apologized too but i said not to worry about it and that i enjoyed it. idk why i said it. she laughed and told me to freshen up and shower.
what should I do next time
