Продвинутый метроном, игра с дыханием, инструкция по

Stroke your dick to the beat of the metronome. I'll turn it in faster and faster as we go. When the metronome is on, you can stroke, but you have to hold your breath. When it's off, you can breathe, but no stroking. This video features nice long breath-holding sessions, for more advanced breath players.
