Very pleasantly.

To Ritsuka's mild surprise, Olga had dragged him not to her room or the office, but to his own room. He didn't really have time to say anything before Olga threw him onto the bed. "Get undressed." She said in a matter of fact tone, Mash coming in as she said this.

Ritsuka nodded as he complied, stripping out of his Chaldea uniform as fast as he could. As he looked over at Mash, he noticed she was doing the same, clearly going to be joining in. "How is this going to work, Director??" Ritsuka recovered as he lied down on his bed naked. He looked over the smaller form of Chaldea's current head. She was a bit shorter, but she did look human, even down to the sexual components.

"Da Vinci said I'd have to get used to this body. It may not be as sensitive as my old one, but it does have some sensation in it. So I'm going to have some stress released after today!" She shouted as she got over Ritsuka, lowering her naked body over his cock.

It was already mostly erect, so she didn't have much trouble entering. It was smooth and warm, seeming to close around it till his member just fit. She started moving up and down, stroking it delicately. Suddenly, Mash was there, licking the the shaft where it met Olga's new sex. "Having fun, Mash?" Ritsuka says, through both his own and Olga's moans.

"Yes, Senpai!" She says loudly and excitedly, before resuming her activity. He had to admit, he loved this adorable Cinnamon bun. She was really giving it her all, even without prompting. Though, he thought he could improve this situation for them.

"That's good Mash, but I think Olga needs it more than me. Why don't you get behind her and massage her chest." The eager kouhai jumped into action, Olga's moans growing more intense.

"O-olga, since Da Vinci built that body so it could have sex, d-doesn't it make sense she'd normally add a bunch of sex toy functions in?" At these words, Olga pondered and focused, before moaning extremely loudly. Ritsuka couldn't blame her - he was moaning pretty hard as her sex had begun vibrating around his dick, as had her breasts in Mash's hands.

"I-I'm CUMMING!" He shouted out, releasing directly into the director of Chaldea's artificial snatch. Collapsing limp onto the bed, Olga and Mash kept going, Olga looking at him as she slowed down her vibrations. "Haaah, a-already out of energy, Ritsuka?"

"Y-yeah, I think I'm spent for now... I think you have more stamina then before, Director." Ritsuka panted out, Olga nodding as Mash fondled her. "I definitely feel it, though I do feel less stressed. And, Since you need rest, I just have one last thing to say to you." She said, blushing and pointing at him imperiously, Mash licking the nape of her neck and making her shiver. "C-call me Olga from now on. I feel more relaxed when you do that." She turned into Mash and started frenching her, but Ritsuka couldn't help but think she was also trying to cover up her embarrassment.
