SRTS/Kiss them both
From Create Your Own Story
You decide to kiss them both with the intention of having them kiss each other. That way you can ensure they will do it when your cum is in their mouth for the first time. You say, "Now I am going to kiss both of you on the lips."
They both look overconfident as they nod in agreement. You believe they think it is a simple peck, so you make certain they understand fully by saying, "It is going to be the same way mommy and daddy kiss."
They both look worried, but neither back down. Anna asks, "Like with your tongue in our mouths?"
You nod and say to her, "Yes. You're first." It doesn't really matter to you which one you start with, but Anna is the one that asked, so it might as well be her.
You place your hands on Anna's cheeks and slowly press your lips to hers. You work your tongue into her eager mouth and she releases a soft moan of pleasure. As you kiss her, your hands slowly caress her ass. You feel her tongue play with yours and love the feeling. After ten seconds you break your embrace and release her ass.
You can tell she wants to say something, but she is unable to find any words. Then you move on to Sue and repeat the process with similar results. You know you can't keep calling everything a tie so you have to give the points to one of them. You look at them both and say, "It was close, but Sue won."
Sue smiles at her sister while Anna gives her a nasty look. You don't want them to fight so you quickly say, "Don't worry, Anna, it is a long contest and you can always win the next one."
Anna drops the nasty look and smiles as she says, I am going to win the next one no matter what."
Sue says, "No you won't. I am going to win."
Before they can start fighting, you say, "How about we find out right now. Kiss each other." They both looked shocked at the idea of kissing each other, so you quickly add. "While you are kissing, I am going to touch you in different areas. Whichever one breaks the kiss loses."
There is no hint of backing down from either of them as you watch them force their lips onto each other. You can tell they are both fighting for dominance as they work their tongues. You reach out so you have one hand on each of their asses and start to caress their flesh. Then slowly start to increase the pressure to determine if either of them are willing to give. Neither submits so you take your fingers and lightly dig in. They continue their battle of tongues as you increase the pressure and know it is hard enough to be unpleasant for both of them.
Neither are willing to stop so you squeeze their asses hard to force one of them to break the embrace. It is Sue that breaks first as she moves her head back with a cry of pain. Anna, though also in pain, has a victorious smile on her face. You know that they can tolerate some pain, so the idea of fucking their assholes is not far fetched.
You say, "Anna won that round. Looks like it is back to a tie."
