Summer Tsubaki-san, a cute smiling pure-type mature woman. Although she actually likes sex, she hasn't had sexual activity with her husband for the past 10 years, and she hasn't even cheated seriously, so she's feeling a bit frustrated. Tsubaki-san, who is often said to be S-like but is actually very M-like, wants to experience a "melty sex" that she has never experienced before with this AV appearance. She was Tsubaki-san, who showed enthusiasm for the shoot, saying that she wanted to enjoy sex to the fullest and feel good within the limited time!
