Caged Blowjobs
Not a porn picture, sorry, but something better: a description of the real thing from Magdala’s Submission:
So I crawled across the floor, stripped and put my clothes away and crawled back to him. He opened the cage in the time it took me. Kneel up. It was neither a request or a demand, simply an expectation of compliance. He placed the steel collar around my throat and locked it then directed me into the cage. Then he padlocked it shut, a move he has never made before. He always latches it, but has never padlocked it. He allowed me to suck his cock through the bars then pulling away from me leaving me pressed to the cage and grasping at the bars as he went to shower. He returned to check on me, and offered me his cock to suck again. Greedy and hungry with lust I fell on it starved. The cage does that to me even if nothing else does. He took it from me again leaving me more alone as he went upstairs to shave and choose clothes.
