Have a look at this cute girl, fully exposed on her balcony. Now we will do a little humiliation task. Nothing considerable, I promise because I won't ask you to walk naked through your town. But :-) I think, well, I order to take your nipple clamps or pegs, attach it to your nipples. Further, you will put on a shirt, anyone will do, you are not out very long. (if you are really a chicken, put a jacket over your shirt but it will cost you to go back to page 38 and do it again once)
Have a look at the picture again. Do you see the man on the left, or even to woman walking on the streets at the right of the girl? Haha she is so fully exposed and not even looking if others are staring at her. Such a slut, isn't she?
Now stroke your cock slowly, you need an erect cock. You take your box of cum in your hand. You put on some trousers (no underwear and no jeans, something lose) and you will go out into the garden (or if you chicken out, onto the balcony). There you will wait 5min until you have to swallow your cum OR if you see anyone walking near you, you need to drink it immediately when he sees you. (he needs not to go besides you, if he is 20meters away, it's also ok. But the nearer, the more humiliating haha) Don't worry! I am pretty sure he will not notice that you drink cum. It's just like a shot, or did you even fill a glass with ruined orgasm? Hahaha Pathetic!! However it is more likely that he notices bulges in your shirt or the bulge in your trousers is it? Haha
Go back into the house.
