>>45143472>60% chance they stay together afterwards. Eventually they could even marry another person together.That's way too high IMO. It wouldn't surprise me if they got to the point of fucking, but staying together is a snowball's chance in hell especially when new love interests will inevitably catch their attention. They might keep screwing around behind the backs of said love interests, though.
>>45143513Very low, once you get to the point where you're playing around with each other you either come to the conclusion you should stop or you go all the way. More so if they can actually read each other's minds and confirm they both wanna keep going.
