Bound Slave Locked Back in Chastity Then Left Alone Naked & Blindfolded in Abandoned Barn

I took my sub to an abandoned barn for a bit of bondage and alone time (abandonment play), once inside, he was promptly stripped naked and blindfolded ready for his ankles and wrists to be chained to some metal bars. Bound and vulnerable I lock his cock back into a chastity cage where it belongs and then inform him I will be leaving him there and vulnerable while I go and have a nice relaxing bath and he can wonder how long he'll be kept there!
