Inside but with a twist

Author's note: I want to thank Zenxraider for introducing the RWBY thread to this great story and so give me the idea to write this chapter.

You really wanted to come inside this gorgeous woman but didn't want to get her pregnant until you were sure how many of your powers would your children inherit. So, with a silent wish, you ensured that Yang Xiaolong would not be impregnated until you desired it. With that out of the way, you drill her deeper than ever before.

"You are going to make me cum too!" You groan as you were almost ready.

That was when Yang started to look concerned for the first time since she gave in to the pleasure you were bringing her.

"Wait! I am not on birth control!" Yang cried out. "You can't come in me!"

Instead of answering, you use your powers to trigger her orgasm, which was by far the best one she has had until that point. The buxom beauty screamed in pleasure, her eyes rolling to the back of her head as she instinctively locked her legs around you. That was when you came with a roar and totally fulfilled that fantasy of yours.

Both of you were panting for a while at the spectacular sex you two shared. Then Yang used her legs to roll you over the padded floor, straddle you with her naked hips and punched you in the face.

"Argh." You grunt as you automatically put your palm in your head but knew that she couldn't really hurt you; even if she wrongly assumed that it was because your aura wasn't depleted. "What was that for?"

"You came inside me after I told you not to!" She growled.

"Don't worry, you won't get pregnant from me," You said without thinking.

"And why would that be?" She asks with a raised eyebrow.

Suddenly you realize your mistake. You didn't want to tell her the truth or make her into a mindless slut that would just go with it like nothing because you wanted to preserve her character traits. But now you told her something hard to explain otherwise.

"Well?" She demanded as she looked at your nervous expression. "Spit it out!"

You don't know if it was your newfound omniscience is to blame or some other power but you suddenly get a flash of inspiration out of this predicament that you are determined to try out.

"You see," You swallowed as part of the tense act, "I can't impregnate women when I am using my semblance."

Yang titled her head in suspicion and you had to remind yourself that she couldn't do any lasting harm to yourself.

"And what is your semblance?"

"I can heavily increase the lust of females," You said slowly, "and by extension make them experience amazing sex."

There was absolute silence in the gym for exactly two seconds before she slapped you as hard as she could.

"I can't believe you took advantage of me like that!" She yelled. "Who do you think you are?"

"Someone who appreciates incredible beauty when he sees it?" You said weakly.

"Don't give me that!" She said as she shakes her head, her long blond hair moving across her naked back as she did so.

You raise your hands in surrender and silently wish for her to calm down, only slowly so that she wouldn't suspect further manipulation.

"Look, I am sorry, I just saw you and thought to myself that you were one of the most beautiful women I had ever seen and I swear that I wouldn't have tried anything like this if I had lost the bet. But I know you are mad so let me make it up to you.

"I don't want anything from--"

"I can help you fulfill your fantasy with your teammate, Blake Belladonna."

Yang froze and you smirk inwardly as you thank your omniscience when you learn that the shippers were right.

"How the..." Yang shook her head. "How the hell did you know about that?

"A side effect of my semblance," You say with the straightest face you can manage. "Whenever I fuck a woman, I learn if they are also attracted to females as soon as I cum inside them and more often than not I learn the name of the female that features most prominently in their sexual fantasies."

Yang's jaw drops to the floor as you say that and you notice that your wish for her to calm down slowly is starting to take hold but she will be able to rationalize it due to the shocking offer you were giving her.

"Allow me to sweeten the deal," You tell her with a grin. "It doesn't have to be today of course but if you want me too, I will also treat you to the spa day you really wanted only that we can invite Blake and you two can get a fantastic happy ending."

It was barely noticeable, but you hear Yang inhale sharply at that after a very brief look at her pussy, you realize that she is getting very wet at the ideas that you are giving her to further fuel her fantasies.

"Or," You add, "In case you would prefer to practice lesbian sex with someone else before going all out on your crush, I can arrange that as well. Really, I want to make it up to you and if I can't deliver, you have my permission to punch me where no man ever wants to be punched."
