H-cup Akari Niimura joins the popular series devoted to developing the Spence tail, presented as the breast's G-spot. A specialist massages her breast tissue until she arches, convulses, and experiences deep breast orgasms that erase her doubts. Nipple teasing during penetration makes her scream and squirt, while toys leave her knees shaking and bladder leaking. The training works so well that she cums during titjobs, then rolls her eyes and gushes through a crushing orgasm from nipple stimulation alone.
