[Synopsis]

The protagonist, Shota Sakurai (26), a humble office worker, meets and marries his older wife, Makoto (28), a former delinquent.
Despite being dominated by Makoto, the couple lives happily and peacefully.
However, their nighttime activities aren't going so well, likely due to Shota being overly considerate.
One day, Shota's boss, Ryuji Hino (28), comes over to his house.
Hino and Makoto, both former high school delinquents, get excited about a common topic.
Shota, who dozes off for a while, wakes up to find Hino kissing Makoto.
Upon witnessing this, Shota freezes, face down and in a rage.
Enraged by the kiss, Makoto attacks Hino but he ends up pinning her down and stripping her naked.
After pinning her down, Hino forcibly performs cunnilingus on her.
At first, she resists.
However, Makoto climaxes before Hino's technique.
After Makoto has no strength left after cumming, Hino quickly thrusts his extra-thick cock into her.
Unlike Shota's, Hino's cock reaches deep inside her, causing her to cum again.
For the next few hours, she is unable to resist as he plays with her body.
For the next two weeks, Shota and his wife seem to be living their lives as usual.
However, Shota notices something unusual.
After seeing Makoto off to work, he pulls out a hidden camera he had set up in the bedroom.
What he sees on the screen...
