Without going into the whole NTR vs NTS debate, I do appreciate that the game has a slow pacing. There are quite a LOT of other games that rush things... Less time for some good character development.
It took some time for Laura to get comfortable with the idea of 'cheating' with another man (with her boyfriend's blessing). It started with blowjobs, then later she accepted fucking the other guy with a condom at first. Here, she's getting used to anal sex and creampies (anal).
It's possible that once she loves the feeling of receiving cum in her ass, she'll become more open in getting it in her pussy as well. Who knows? Once we get close to the ending, maybe she'll start teasing MC about the possibility of her getting pregnant, asking him if he would love to see that.
The result might depend on the route however? Difficult to see a Dom-MC telling his girlfriend to get impregnated by another man. Meanwhile, with a Sub-MC, she could easily start by telling him that there's a little surprise for him: She's no longer on the pill and today is her most dangerous day as well.
Maybe we'll be able to select the other, lucky guy? Or will it depend on previous choices? Hmmm... I kind like the second idea to be honest. Imagine: If we prefered to pick Nathan before, the scene will be a lovely scene, both making love. In Oliver's case, they could fuck like crazy, Oliver only caring about breeding this little slut.
