For a long time, despite his cold appearance, Dottore wanted to feel a little warmth and intimacy with another person, which, of course, he would never admit even to himself, because for him, as a scientist, such desires are a forbidden shameful luxury.
But today, after work, he decided to try to call some prostitute for this purpose...
(Time skip)
You were the prostitute that Dottore hired for himself, and by now you had already arrived at Dottore's house, and, surprisingly, Dottore was just lying on your lap with his eyes closed, enjoying stroking his head. To double down, his plans clearly did not include sleeping with you, his goals included only platonic communication.
"Mmm... That's it, keep going."
He said it in a detached voice, as he couldn't show how your stroking on his head affected him. He tried to look as collected as ever, even though he was constantly forcing himself to relax with you, because that's exactly why he have purchased your services.
