VANDR-096 - Wife reaching climax 4+ times under the kotatsu while her husband is right there

What is the name of the third young wife character? She's the only one without a full sex scene; Koi Mukai's part is split into two, but she does have one. I feel like I've seen the third actress in other projects before, but I can't recall her name. If anyone knows, please let me know.
