----------------------------------------
Koudai and Sumi have been friends for a long time.

Koudai likes to use the pet camera set in Sumi's bedroom to take a look at his cat.
But then one day, Sumi turns him down, saying he wasn't free that evening because he found himself a lover.

The two of them have always been very close, but for some reason, Sumi has never introduced Koudai to any of his dates. Curious about the kind of woman Sumi might be into, Koudai decides to take a peep using the pet camera on that night...
----------------------------------------
* The two of them aren't exactly in a relationship, but they kind of act like an old married couple, so having his "wifey" Sumi held by some random man does feel like cuckholding.
* Koudai is only watching the sex scene between Sumi and the anonymous man.
* Be warned: Koudai never shuts up through the whole thing.
