All i ask for regarding these kind of games is some occasional entertainment and stimulation. The last thing i want to waste my time with is analyzing the mechanics of cheap thrill products. But the lounge scenes with mom and Deon have caused so much unnecessary controversy here that i feel this still needs some exploration. Here goes :
The first time it happens is day 6 or 7 at 9 PM. If you enter and then leave it is still 9 PM.
Therefore it is impossible that they could have sex in the meantime. If this is a glitch that escaped the devs attention or intentional is unknown to me. Ask him. Same goes for the touching. If you enter again you see her lying on his lap. Leave, and it is 10 PM.
These two scenes have led some people to believe or suspect there is NTR in the other path. For once, sex is ruled out, see above. That leaves the intimacy and the conversation. The whole affair implies that Deon is still after mom, and she doesn't look exactly reluctant there. Maybe this is to be taken as some kind of warning sign : If you don't care for her, she will (again) fall for him. Whatever the case may be, the scenes are contradictory and not well explained in the scope of the game.
Once you proceed with the game, you will find that the first scene is missing from then on : No touching anymore, she is just lying on his lap and time passes correctly ( time frame day 6 -14 ).
This shows sufficiently that there is no NTR in the other path : Only the possibility that it could happen if you don' t care for your relatives. Deon is kicked out sooner or later, and the intimate relationships between MC and family improve. Any questions ? Or did i make myself clear this time ?
