Oh, and I would like to apologize for almost unreadable long sentence in my last post before ** sign. I was probably too excited when I wrote it to notice autocorrect made a mess of it. I was just thinking too much about your last image as: hey, these two girls, especially the one on the right, are looking to be very interested in this, so I hope they won't be just looking at the action and also give a helping hand :)

I was thinking how easy or hard would be for them to tie his thing. The very tip, no problem, but the foreskin after it would be very inflated? I don't know, but it it could be a challenge. So I imagined his sister would take a long string, tie it just behind the baloon, give both girls loose ends - one from left, one from right - and let them slowly pull it. It begins to tightening up, his glans inside pushed more towards body, and after a while - voala, very tight knot and the baloon is ready to be cut off. Not so funny for the boy, but I think he kind of deserve it. I imagine how his cock would then pop to the light almost like a spring, ready to be cooked naked :)

Of course, only if others find idea interesting and you will have fun making the story ;)
