The temptation of her sister's wet "divine breasts" is too erotic... During the 24 hours that she was away, I fucked her so much that I released a lifetime's worth of sperm...!

On a day of torrential rain, her older sister, Mitsuki, came to the house soaking wet. "Even though we live together, don't you have sex every day? If it were me, I'd be pissed." While she was away, I succumbed to the temptation of her transparent H-cup breasts and sweet voice...my rationality collapsed. I had immoral sex with my sister many times...! I kept lusting after her disheveled hair and wet divine breasts, and I was riding her in cowgirl position on the couch! Fluffy titty fuck in the bath! Divine breasts jiggling piston in bed! ...Even when the morning came...we fucked so much that we ejaculated a lifetime's worth of cum!
