Phil's normally straight-laced wife Laura has long held a secret fantasy of seeing her husband with another woman. When the sexy Donna comes to stay, things quickly get steamy after Laura gives her blessing for them to play together. But she doesn't anticipate what will really happen when the sex-starved Donna gets together with randy Phil. Donna has lusted after Phil for years, so the action quickly gets explosive.
Before long, the fantasy threesome becomes a reality, with both lactating women engaging in sex games and multiple milky sex sessions with Phil, leading to the women engaging in lesbian sex and pushing the boundaries further than they could have imagined.
Things get more complicated when Laura has to go work- and Phil and Donna are free to explore their wildest fantasies. Before long, they find themselves in a situation, which it will be difficult to return from. Will things ever be the same again?
