After her husband passed away, Ryoko is left alone with her stepson. What was supposed to be a peaceful family life quickly turns into a hotbed of lust. Watch as she uses her massive, curvy ass to seduce her son, riding him until they both reach an explosive climax.




















I usually like the making-of footage at the end because it gives a feel for the set's atmosphere, but this time, it felt way too much like the actors were just 'doing their job.' Seeing the staff being so careless really killed the mood for me.
She holds nothing back. It starts right off with a full-nude shower scene from Ryoko Murakami. From there, it's non-stop—masturbation scenes, sex scenes—she's so busy getting down to business that there's no time to put on panties, and the story is completely sidelined. Ryoko Murakami is amazing!
Murakami keeps hooking up with her son's friend, and the shots really highlight the 'big butt' mentioned in the title, which is great. Her signature squirting is a bit toned down here. When the semen is spat into her mouth, she swallows it properly. The anal licking is visible even through the mosaic, which was a turn-on.
My dick getting crushed by those thick, voluptuous cheeks. The scene where they lick each other's anuses in the 69 position is the absolute pinnacle of erotica. I really want to see more new anal works from Ryoko.
Ryoko Murakami plays the stepmother who seduces her son and his friend. The behind-the-scenes footage, bloopers, and interviews after the drama are quite entertaining. Ryoko Murakami is actually quite cute in real life.
