Kakiuchi Mayumi(垣内真弓)

Kakiuchi Mayumi is a Japanese Adult Video (JAV) actress who debuted around 2015. Based on available information, her career appears to have been relatively brief, spanning a few years. Her work primarily falls into the mature woman ("熟女", *jukujo*) genre, with notable emphasis on themes of lesbianism ("レズビアン", *rezubian*) and NTR (Netorare/Netori, "寝取り・寝取られ"). She is also tagged with "巨乳" (big breasts) and "ぽっちゃり" (chubby/plump), suggesting these physical attributes are part of her appeal. One of her identified works belongs to the "寝取られ熟女" (*Netorare Jukujo*) series by Ruby (ルビー). This suggests a potential focus on series work within that studio, although further information is needed to confirm the extent of her involvement in series productions. Overall, Kakiuchi Mayumi appears to have carved a niche for herself within the specific subgenres of mature women-focused JAV, appealing to audiences interested in the combination of mature beauty, lesbian themes, and NTR storylines.
