PPPD-434 Yui Hatano gets breast development treatment at a Spence gland clinic

Yui Hatano is the patient at a clinic that specializes in the Spence mammary gland, an area of the breast that responds to stimulation the way a G-spot does. She climaxes so hard she says it is the first time lightning has run through her, and she loses control of her bladder. The specialist works on her breasts until she is soaked and overwhelmed.
