Let's have some relaxed anal sex in the outdoors, surrounded by nature! The one who invited us was Shiokawa Undan, who has a masochistic personality! While we were traveling, she masturbated anally with a nonchalant look on her face, but the staff member sitting next to her looked confused and enjoyed the experience! Pushed by the openness of the greenery, Uni stuck out her ass and felt exhausted when her anus was licked, and entered a state of "I'll do whatever I want!" When she deep-throated the big dick, her anus and pussy began to twitch and throb, unable to wait any longer... As a warm-up, Uni was first inserted into her pussy, and every time she pulled out the big dick, she leaked out loud. Not satisfied with just her pussy, she spread her legs wide and begged, "Please put your dick in my anus!!" She opened her legs wide and desperately loosened her anus with a vacant look in her eyes to accept the big dick. With her mouth half open from the pleasure, Uni surrenders her whole body to the men. After being thoroughly made to climax by the men with toys, her pussy becomes engorged and starts to move, squirting with each movement. With her nipples rock hard, Uni has a huge dick thrust into her anus and pussy, filling both holes to the brim, and she moans wildly in the pleasure she cannot escape!! The limited edition includes a special behind-the-scenes video. This time, the location shooting is outside the studio, so instead of the usual close-up video, we have a video focused on an interview. From the origin of the name Shiokawa Undan to the pet she lives with, this video is packed with the real Uni-chan.
