Nice game and setup, the women looks jacked.
The risk of the wife getting pregnant is also nice.
It would have been funny if the wife didn`t allow the money and the friend lost his place.
So he then had to move in with the couple.
But the male MC being an submissive, small dick cuck, already from the start is a little boring.
It also should have take a little more for her to make out with the MC friend in the start.
Will there be only cheating if the male MC asked for it?
Then it`s kind of no cheating just cuckolding.
Some proper cheating path, where things happen against the MC will, would fit the dominant wife.
