SSNI-633 A 3-day record of relentlessly fucking her sister from morning till night while she was away on a business trip. Sakamichi Miru

"Who do you like more, sister or me?" Me and her promised to marry each other and frequently visited each other's rooms. I thought such happy days would last forever... until that day... When she left for a business trip, my younger sister actively seduced me. Despite feeling guilty, I had sex with her repeatedly until I was spent. The days filled with sex with my sister were the most lewd, crudest, and most exciting in my life, especially during those three days when she was away.
