An amateur woman with 103cm I-cup breasts met through Twitter was gradually persuaded over six months to appear in this video. She's a genuine nymphomaniac who goes into convulsions during sex. As a condition for appearing, she requested to co-star with her favorite AV male actor, and this shoot fulfills her wish. Since she refuses to show her face, she performs wearing sunglasses and masks. At her own request, a threesome scene is included, allowing full enjoyment of the eroticism of double penetration with simultaneous dual-orifice insertion.
