Hm it started pretty good, but then story went quick downhill to already simularities with other VN i seen. If you want to keep it unique then don't start copying those already excisting stories. What I mean is the husband suddenly screwed up, which is probably staged by Marcus the boss. Also what bothered me is the MC had first sex scene a big cock and looked like a well endowed man, even he was pretty good in bed. Second scene suddenly already changed that, his cock became more the size of Marcus cock only thinner then how is cock was first. Also the ntr isn't really avoidable, there is no choices for mc to make it stop, instead you only get one choice to not see it or to see it.
I had my hopes up for this story, but now i have doubts as it no longer interest me anymore, you made the mc first look like a possible bull, and confident man that could win from Marcus, but in second chapter you turned him with some simular already excisting story into a cucky. So the only way i see this going is the mc get the other girls while his wife be Marcus cumslut. But the part you make the mc look like some screw up saddens me.
