I pop a 14mm triple-ball sound in and out of my peehole like it's nothing- and for my huge stretched urethra, it really is. The room was chilly, so as I got started, the Collins speculum was so cold it made me giggle, and the treble sound was startlingly cold as well. Even a 14mm sound is such a loose fit in my pisshole that as I thrust it past my bladder sphincter, a stream of pee shot out past it! You'll see this happen several times, until my bladder has emptied. Then I get my vibrator and start pounding my bladder sphincter as I buzz my clit. By the time I've finished cumming, holding the sound to my big clit shows me that it has really heated up!
