Definitely a promising start. Beautiful renders, a nice pace, and your replies here are thoughtful and show real insight into the stag/hotwife lifestyle. As others have mentioned, there are a couple of minor quirks that can distract from an overwhelmingly positive first impression - most notably MC's small penis and Debbie's lazy eye. Also, I always cringe when a woman is depicted as averse to porn (and to her hubby watching it). This makes her come off as a bit of a prude, and to me puts the relationship at a point that is miles away from her becoming a shared wife. Which means there is a danger of her arc being either very slow (A Wife And Mother) or feeling rushed (unless you plan on using a gimmick like the necklace in The Office Wife).
Apart from those nitpicks, great work! Now if we could only fastforward to a game state three years in the future...
