Kevin's training slowly continues towards his goal of being allowed to cum on her black leather boots. He has seen various porn movies where the submissive men got to spurt onto the boots and had to lick it up directly after. So far he has fantasised a lot about this and told his girlfriend who is willing to take on the dominatrix role in this.
While talking about the next steps in his training, she suggests to feed him precum to get used to the salty taste while he is still horny. This idea makes him instantly horny. As usual he asks her to go to the bedroom immediately and try it out, but she declined sweetly. Putting her hand onto he check and slowly pushing her thumb into his mouth she said "let me finish a few things, we'll do it in the evening." His mind roaring and imagining how it will feel like he was unable to finish things himself and ended up browsing the internet aimlessly.
The sun set and he goes into the bedroom to set everything up. It excites him so much that he can barely contain himself. He feels the precum leaking already and thinks that she will have it very easy later to get sufficient precum to shove into his mouth. It is a very wicked game: the hornier he gets the more humiliating it gets for him. And as his obsessive with the game clearly shows, humiliation turns him on.
From one drawer he takes out the black leather cuffs for his wrists and ankles, as well as the matching collar. Wearing it makes him feel more submissive and sometimes she grabs him by the attached ring to pull forward. From another drawer he takes out the dominatrix outfit of the day: hotpants, top, cap and gloves, of course everything in black leather. He attaches the short ropes around the posts of the bed and joins the second ends into the carabiners. He removes his clothes and then diligently puts on the cuffs, ensuring that they are put on all in the same direction. Last he closes the collar and tries to fine a setting that it is somewhat comfortable but also strict enough to be effective. It is time to join the ankle cuffs with the carabiners, he also does one wrist. The other one has to be done by her.
"Honey, I'm ready," he lets her know in the living room from where she replies with a telling "Is that so?" He listens carefully for the sounds of her getting up, but she takes her time. Right now he is the one who wants, so he had to be patient. Eventually she comes over and seems to ignore that he is laying there naked. She sits down next to his free arm and asks whether she shall him it up to the carabiner, her way of asking for consent before the game starts. "Yes please," is his prompt response and she smilingly does the little missing action to make the bondage inescapable. This moment is always a turn-on for him.
