A project to play with amateur girls and have sex, and also have them introduce their horny friends. This time's friend is Mayu-chan, who experienced her first time at the age of 19 and has only known one man since then, and who is serious about everything and shy. She says, "Because life is only once, I want to live as I please," and "I want to be a different me." When Mayu-chan's nipples, neck, and inner thighs are touched, she feels it and soft D-kissing, stroking her proud beautiful ass, and when the electric massager is applied to her clit, she makes a faint moan of "Ugh, uuu, uum, ah~" and says "It feels good~" and comes with a thick tongue kiss. Mayu-chan, who says "I want to touch your dick~" and rubs her dick with a slightly satisfied look, when her shaved pussy is given intense cunnilingus, she moans loudly, so when I insert my dick into her soaked pussy, she raises a loud voice that echoes through the room, saying "Ah~, uh, ah~ it feels good~" and I shoot thick semen onto her breasts with intense piston thrusting & spanking, bringing her to the brink of climax. She said, "It felt good..." while being shy. Furthermore, Mayu-chan introduced me to a cute girl. Mayu-chan, who is serious about everything and lives a relaxed life, not wanting to be home too much, was a very horny girl who watched lovey-dovey AVs when she masturbated. Mayu-chan introduced me to a super erotic girl.
