We'll consider this a fairly remote dead-end future, but for now, Kevin has an irresistible desire to satisfy his base sexual needs! Kevin enjoys the present and is so carefree that he doesn't think about the possible sad consequences in the future...
Kevin's girlfriend was a slut before she met him, with Brian. It didn't take much persuading by Kevin for her to cuckold him repeatedly once she got going again with Mark. Lucretia has been corrupted by parents, former lovers, & now going even deeper into infidelities with more men and women as the story progresses - at work, neighbors, ex-lovers, etc. At a certain point, she has become a total unfaithful slut, and the netorase aspects of the story have gradually faded into the background.
