Two hours after her first sugar moomy activity... a record of a married woman who was cuckolded in the couple's bedroom.

She is desperate to be loved by a young man... Her body bends backward under the violent use of her hips. This kind of relationship is absolutely wrong... but every time she is made to cum, her heart is filled with satisfaction...
Maki is a lonely married woman who is left alone by her husband. She is a lonely married woman who is neglected by her husband, and the only person who understands her is a boy named Satoshi who lives in the neighborhood.
One day, out of loneliness, Maki turns to an app that allows her to meet up with other men. But the man she meets up with is Tomo...?
Tomo, who actually thought Maki was beautiful, used the sugar mama activity to come on to her. She kisses him for the first time in a long time...and even though he resists, he persistently makes love to her sensitive spots, causing her to pant and leak her love juices.
The intense intercourse is already pushing her to the limit of her rationality... but she can't resist the hot cock...

I like colorful but this one doesn't have scenes as hot as Urakan and Minazuki Mikka.
