Erina Sugisaki, 32, is a slender housewife whose elegant one-piece dresses complement her slender figure. She looks like a model. She speaks with a calm demeanor and is a highly intelligent woman. She married her husband, who runs a sports gym, five years ago. He's the owner, and she's a banker. They have no financial problems, but their only complaint is sex. Five years later, their relationship is still going strong, and they still go shopping and travel together on weekends, but they've completely stopped having sex. Unable to bear this complaint, she even had an affair with her boss at work. Erina enjoys being blindfolded and having her arms tied. She's quite fond of it. He caresses her buttocks while pressing his erect penis against them. "Your big crotch is... touching me..." she replies lasciviously. When she removes her dress, she's revealed a super-thin thong, barely noticeable. The thong, paired with her firm buttocks, is quite obscene and arousing. Her breasts are white and soft, an F cup. They have small, pale pink nipples in the center. When I push aside her ultra-thin thong and stimulate her clitoris with my tongue, she lets out an unimaginable moan and squirts out a huge amount of juice. After carefully licking her from balls to tip, I insert my rock-hard cock. I thrust it deep inside her, thrusting it hard over and over again, finishing in her mouth. Erina, who is quite a lover of this kind of thing, had a satisfied look on her face.
