Why not both?

"You could ride me for starters. And if I feel like it, I can always include my hands, can't I?" She smiled and crawled back towards him.

With the same elegance and speed in her fingers as before, she unleashed his dick. Her eyes, however, were glued to John's face. He remembered how harsh he had been to her before, as she looked at his dick with only a little bit of amusement, so she probably wanted to avoid this. Well, back then, he was still a guy with a below average dick. Not any more tho.

She reached down and either was not surprised at his growth or she hid it perfectly, because she motioned it directly onto her most private place, and inside of it.

"Soo, I should explain myself more clearly. I want to be of service for my... boyfriend. Or master. Or the guy that just walks up to me so he can use my cunt for his pleasure." she thrust herself down on his pole to emphasize this. "And I am really insecure about myself. Don't say anything about this, okay? You will only make it worse, even if you try to help. I always think I am not doing good enough, not doing enough. So I started doing everything. I really want to do EVERYTHING for him." she clenched her pussy around him while starting to move.

"In return I want him to demand everything from me as well. I am jealous. I don't want a guy I am serving to ask another girl for something. If he needs something, I do it for him." Wait, did that mean...

"So as I made that random girl on the train a bit hot, so she could get molested by your friends... you were jealous because you wanted me to **** YOU to be molested by them?" She looked aside.

"It wouldn't be molesting, I would have let them done it. If you asked me for it. I don't want you looking at other girls. Or porn. I want the boy I am with to be with me. So if he has a fetish, he tells me, and I do it." This sounded really good. Just two days ago, John would have murdered to get a girl say this to him. Today, though, he was different. He had a hands on situation with his mother, a prostitute/gamer friend coming over later today, a school teacher who showed him a lot more affection than needed and the skills to get even more girls. So the limit 'dont even look at other girls' suddenly sounded a lot more restricting than it would usually do.

"And what if I want something you don't want to do? I don't want to **** you into it." She laughed, honestly and out of her stomach. Which he could feel, because it send vibrations over his dick.

"If you like something, that is like a **** of nature for me, and I will either like it myself, or will do it because you like it." Okay, he got that.

"But what if I overdo something and demand too much. What if I demand something you absolutely would not do? Or what if I demand something you can't do alone?" She thought about this.

"If you demand something that I could do, but refuse to, then you may do whatever you wish. Kill me for it, **** me physically into it, whatever. I consent." She was about to move on as she saw John's look. "Yes, if you are in that situation, which will never happen, then you may get another girl as well. Jeez, you are such an asshole, I am literally giving you my cunt right now, and you are asking what you have to do to get another one." she softly shoved him back, which was enough to make him fall onto her bed, and his dick move inside her abruptly.

"About the other question. If you ask something that requires more girls than me, I will get them. I have some girlfriends who would be willing to do some stuff in groups. So... what do you want me to do first? I am at your disposal. As long as you are loyal to me!"
