Great comment. I wish others would comment in as greater detail.
As for me, I've only managed to cum once whilst standing up. In the shower, after a week of abstinence!
I want to congratulate this young man on his immaculate behaviour. He didn't make a mess at all, wank, spunk into a tissue and flush away. Next time you should abandon yourself and cum everywhere.
Thanks for posting, griffi.
Xxx.
