He has to blow the dildo

"Now take the dildo, and use the suction cup on the bottom to attach it to the seat, in the spot where your cock would be when you're sitting down."

He isn't looking forward to where this is going, but at this point, why resist? They have broken him, at least for now, and he takes the dildo and presses it into the seat.

"Now, start sucking," the voice continues. "I'll tell you when to stop. The computer will tell me when you've made it cum, so the better you blow, the faster you'll finish."

Josh, on his knees in front of the dildo, puts his mouth over the head and starts to suck, swirling his tongue around its tip and then sliding his mouth down the dildo. Sucking the vertical dildo on a suction cup is harder than just shoving it into his mouth, and it takes some time before he manages to get into a rhythm. Nevertheless, he manages to work it out, and in a desire to get things over with quickly, he makes a serious effort. He pumps up and down, up and down, sucking and slobbering on the plastic cock in a way that he never would have dreamed of just a day ago.

"Good work," says the voice. "You're doing a great job; it's sad that such talent was wasted on a straight boy."

The machine translates the motion to his own cock, but without the same intensity as before. He keeps bobbing up and down, feeling the shape and the texture of the plastic cock as it runs over the full length of his tongue. He tries to imagine a mouth on his cock, providing the feeling coming from the machine. But without the video to look at like before, his mind wanders.

With most of the sensation coming from the dildo sliding in and out of his mouth, his mind's eye often flashes to the image of a real man in front of him, whose cock he is sucking, before being quickly pushed out of mind. He tries to imagine it's a beautiful woman who just happens to have a cock that he is sucking, which is a bit more comfortable, but then wipes that from his mind as well: it's still sucking a cock after all.

"Don't worry," continues the voice, "there's nothing wrong with sucking a nice big girlcock. Make her cum, fill your mouth with her warm delicious seed."

Despite the unnerving realization that she was just able to read his mind, Josh presses on, and wiping from his mind the image that the voice just gave him, using the blowjob machine as a guide to what felt good and what did not. Eventually, the voice returns.

"It's about to cum, are you ready?" asks the voice. "Do you want it in your mouth, or all over your face?"

Josh decides to take the option that gets it out of his mouth, and leans back, stroking the dildo as hard as he can.

"You've gotta get low if you want that facial," she tells him.

Josh reluctantly complies, lowering himself and leaning forward until he is level with the cock, continuing to stroke. Soon he feels a burst of sensation from the machine on his own cock.

"There you go," the voice says. "Keep stroking, squeeze all the cum out of that cock."

He does so for a few more seconds, feeling his hand on the dildo against his own cock, but then the feeling subsides, which he takes as a cue to stop. He sits up, returning to a vertical position on his knees before standing and starting to stretch.

"Well done," the voice congratulates him, "you could be a pornstar yet. Why don't you lay back on your chair and relax a moment. The next test is less taxing."
