Basically stories in the style of J267 - wife and husband are reluctant and both in emotional turmoil, she doesn't become slut like in pornos but even tho she is shy she can't help herself doing more and more and giving husband only some details cause she is ashamed and has regrets later, and husband is being turned on but feeling shitty about it. Especially love the theme where he falls asleep and when he wakes up goes to find his wife and spies on her through half closed doors, or sees a tape or something..
