Male's perspective only due to not having a working crack.
Your house burns down and you and your wife move into your bosses really big and impressive house.
Your kind of bewitched by his wife. She's one of those traditional lady-like wife archetypes.
Your boss tells you to have sex with his wife, he has erectile dysfunction (I personally think this is a lie, though I haven't played the heroine route to find out yet)
You say you will, because you want to "repay" your boss for letting you stay at his mansion, but only after talking to your wife about it first.
Your wife somehow agree's (NTR right?), but only on the condition she helps your boss too (she's the sporty competitive type I suppose).
After dinner for a few nights the four of you head to different rooms and you proceed to start the wife swapping.
The wife you thought to be refined is actually a total nympho. I didn't like this much. I think it could have been interesting if she was the refined type all the time.
It starts to escalate when your boss, who is also way more endowed than you are, starts making your wife moan really hard every time the wife swapping commences.
You start to get really paranoid as to what's going on and after a few nights you decide enough is enough and you peak on the two of them, only to find out that his ED seems to be cured, and he's pounding her away like there's no tomorrow.
You ultimately decide to continue the wife swapping. At the very least, I don't think you can decide against it at this point. You continue because your boss "claims" his ED is only partially fixed, he can get hard for your wife but not his. Your wife also seems to be coming up with excuses to continue, at this stage it's pretty obvious she's fallen already.
Wife swapping keeps going for a while, you go to some fancy dinner, and after a sex hotel. This is the first time you have sex without a condom with your bosses wife, I assume the same is probably for your wife too, though i'm betting that it's probably been a thing for a while.
You end up at the villa that the main characters were at in the first game. You get really drunk one night, though it seems you were actually drugged. Your wife and your boss have sex on the bed next to you, you can't seem to move, and it's also the first time your exposed to the fact that he's cumming inside your wife.
I think it continues a bit more, then finally the final decisions are given to you.
One ending involves her getting her hair dyed blonde, this ending I assume she becomes an escort because of that. We'll need her perspective to find out. It then cuts to a future date where your bosses wife is pregnant and you walk in on the three of them having sex after work one day. Your wife doesn't really care to stop and acts as if nothing is wrong.
The other endings are all somewhat similar.
One ending you leave the house with your wife, and she's ultimately disappointed. You don't have a baby.
Another ending you leave the house, your wife has a baby, and then the game starts to zoom in on her crotch. Her jeans fade out, revealing black panties, which then those fade out, revealing a very small pink tattoo with you wife's and your bosses initials. I think she falls in love with him as the tattoo is surrounded by a heart shape.
You get an ending exactly like the above one but you stay at their house instead.
There's also the only "good" ending where your wife still has that baby, you stay at the mansion, but the screen never zooms in on her crotch revealing a tattoo. Who knows?
They're all the endings i've found so far. I assume there's a ending where you fall in love with your bosses wife? I don't know yet.
