Relato de una masturbación

He's tied to the chair (exactly, strapped) , completely naked, and gagged with tape (sometimes I put a folded panty in his mouth before gagging him) His clothes are over there on the sofa and his boxer shorts are in my hands; It's black, smells delicious, I leave it next to the rest of his clothes. He looks at me, and his totally erect penis is proof of how excited he is, his little head looks red and eager for a good caress. I'm standing in front of him, completely dressed (sometimes I undress, but not today). It started by caressing his chest, his nipples (I squeeze them a bit), then moving to his stomach and jumping to his thighs. He doesn't stop looking at what I'm doing and his breathing starts to get agitated a little. I bring my fingers close to his head and caress it slowly, he looks at me and closes his eyes, he's enjoying my touch. I grab his penis, his erect penis with my right hand and start giving him a slow masturbation, enjoying his warm member. I speed up the frequency of the masturbation, and he lets out some moans through the gag. I masturbate him for a good while, sometimes slowly, sometimes quickly, sometimes I stop touching him and start again. He closes his eyes, lets himself be carried away, groans, and also doesn't miss a detail of what I'm doing to him. His head gets wet, my index finger caresses it all, this makes him even more excited. Pre-cum comes out of his penis, I let it fall from his head and when he's about to fall onto the chair, I catch it with my finger and put it on his nipples (sometimes I put it in his anus) I know the explosion of pleasure is coming, so I masturbate him at a constant rhythm and he comes, his semen shoots out, falling mostly into my hand that still doesn't release his penis. At this point, his moans are louder, he moves with the pleasure of the orgasm although being tied to the chair limits his movements. I stay looking at my hand full of his sperm, bring it to my face and sniff it. I wipe myself clean with a towel and him too, slowly, leaving no trace of any orgasm on his body. His penis is... reclaiming my normal form, as his breathing returns to its natural rhythm. I remove the gag and handcuffs, he dresses, thanks me for that masturbation and leaves. And I? Excited, I take off my clothes, my penis is erect, I masturbate and come on the towel with which I cleaned up his ejaculation. I lie back to catch my breath and remember how tasty it is to masturbate someone else.
