Slender beauty Yuki Takeuchi joins the popular clinic series devoted to developing the Spence tail, presented here as the breast's G-spot. Specialist massage sends her arching back and screaming through deep breast orgasms. Teased nipples make her writhe and squirt during sex, while toys bring trembling orgasms and loss of bladder control. She even cums while giving a titjob before explosive nipple-play sex pushes her over the edge again.
