A 72-hour record of a best friend having sex with her best friend's girlfriend from morning to night while she was away on a business trip.

My forbidden relationship with my best friend's girlfriend...I couldn't stand the charming body that was approaching before my eyes... "It would be a problem if this relationship were discovered..." Using Aika's aggressive invitation as an excuse, I justified my affair and greeted my best friend's girlfriend in my best friend's bed for three days. Amidst the guilt, Aika's face is proud of herself, who is scorning herself as she swings her hips with determination to her best friend's girlfriend, but still groans with pleasure. No one knows what will happen like this...
