I didn't realise I had done that, thanks for the info

"accidentally" having women find out my little secret

Imagine finding out your sister and her friends did this and then you see she's the only one not showing her ass in the picture

Depends, when I jerk off to nudes or underwear pics maybe 5-10 minutes, but I can go over 15 if I use fully clothed women unless it's my sister, cause if I see her face or think about her I can never hold it in

Fully erect I can grow up to 6 cm (5 cm if you don't count foreskin). It's about 3 cm flaccid, so I'd estimate it's about 5 cm including foreskin in this picture.
