I'd actually quite like to see you outside, somewhere by water, fully naked. And if you can swim, jump in nude, if you cant swim, then just wank until you cum into the water. Who knows, you may get a fish preggers haha.
the place where I live is now about 0°C so maybe after half year when will be summer I can do this dare but not now but I am open for another idea of outdoor dare but not so long
