You've definitely seen stories about girlfriends having affairs with their best friends when they're away, but have you ever seen one where you have affairs with both of them at once?
In this film, "I had a forbidden love affair with my girlfriend for three days, but I was so bored that I couldn't even have sex with her," S1 has invited two beautiful girls from different generations, "Aoi Tsukasa" and "Otoshiro Sayaka," for a dreamlike co-starring role. What's the plot?
The male protagonist in the film has a lovely girlfriend. Because he frequently visits her house, he also gets to know her two roommates: the seemingly aloof but beautiful older sister, Aoi Tsukasa, and the youthful and leggy beauty, Otoshiro Sayaka!

Even though he already has a girlfriend, the male protagonist is unconsciously attracted to Aoi Tsukasa and wants to melt her icy exterior, so he confesses his feelings!
"Do you really like me?"
"Hmm..."
"Then... if you abstain from sex for a month, I'll do it with you!"
Both knew that his girlfriend (roommate) would be going on a three-day training program in a month, so Aoi Tsukasa made this pact: the male protagonist had to abstain from sex for a month until those three days when he could finally unleash his full potential. Finally, the day arrived. After confirming that his girlfriend had left with her suitcase downstairs, the male protagonist excitedly ran upstairs!

After grabbing Aoi Tsukasa, the two undressed on the bed and then passionately made love repeatedly. However, they seemed to have forgotten that there was another woman in the house, Otoshiro Sayaka! "Actually, I've always liked you..."
But then, late at night, it was Otoshiro Sayaka who confessed to the male protagonist, expressing her long-held secret crush. How could he resist such a cute girl throwing herself at him?
So, the male protagonist and Otoshiro Sayaka had another passionate encounter, resulting in an awkward situation of one man and two women in one room. Their relationship was obvious to everyone, and Aoi Tsukasa reverted to her cool demeanor, sipping red wine and saying...
"Don't worry about me, you two go have some fun, please!"
And the proactive Otoshiro Sayaka really did ignore her roommate, throwing herself at the male protagonist and starting to get intimate. Aoi Tsukasa, watching, naturally felt aroused, and thus, a threesome ensued...

Three people showered together, had sex together, and slept in the same bed. Over these three days, they formed a one-king, two-queen cohabitation sex life. The roommate's best friend, who was away, probably never imagined that her boyfriend would be "eaten up" by "them"!
"Compared to our oral sex skills, whose is more comfortable?"
When she returned from her training, this complicated four-way relationship had formed. I can only say the male protagonist had a really good time!
As the first work in S1's new SSIS series, this film is definitely an innovative and practical gem. S1 not only has a strong cast, but the quality of their recent projects has also improved significantly. Especially after seeing the plot of FALENO from the neighboring studio… I'm really liking S1 more and more!
