A personal, living doll.

All fictional characters in this scene are depicted as 18+

You can't just leave it at your cock. This thing lets you change reality on a fundamental level, and there's so much you can do with something like this. Looking at your cock and seeing its newfound size pulsing, you know you want to use it on something... you could just pump one out, or use the program to make a fleshlight or something, but...

Your eyes drift towards some of the anime posters on your wall... letting yourself linger particularly hard on one of your Evangelion posters, particularly on a certain red-haired German girl who stole your heart as a teen and never quite left it.

You quickly type a first entry, just to protect yourself in case this works.

{ My room is soundproofed and nobody can enter unless I allow them. }

Nothing changes, but you know instinctively that it worked, just like your first entry did. Then, with a little more trepidation, you type your third entry in just as many minutes.

{ A sentient sex doll of an 18 year-old Asuka Langley from Evangelion will appear and disappear for my personal use when I imagine the character and snap my fingers. She will do anything I say but otherwise be just like her fictional self. }

You hit enter, and there's a faint shimmer in your mind before it settles. Turning your chair to face opposite your desk, you imagine Asuka and snap your fingers. In front of you, space warps slightly and in the next second a very high-quality sex doll appears standing in your room. It almost looks like a scaled up anime figurine, and were it not for the way she blinks and seems to mimic breathing, you'd have been forgiven for thinking she was just that.

"U-uh, hi." You say, suddenly feeling all your bravado vanish. The sex doll furrows her brow, looking around the room before turning to look at you and more importantly, your cock.

"Huuuh!?" She gapes. "Gross! Why do you have your cock out, what the hell is going on?"

"Um- stop talking!" You quickly usher a command in a panic, forgetting your room is soundproofed, and watch as she blinks and falls silent. She's still looking around the room, obviously trying to get a handle on where she just appeared, but she's not being so.. loud about it now.

'Oh god, she really does follow commands...' It makes your cock ache, but there's the other angle to be considered that you made her sentient. Technically, if you were so inclined, you don't even have to have sex with her... but you could, and you could make her do anything you want in pursuit of it.
