Reunion with that girl who grew up with me in a nursing home at a creampie soapland

The two grew up in the same facility when they were young. They were just as close as real siblings, but as they grew up, they were separated...I wondered if they would never meet again...but they never met again at a soapland! Rei, who has become a soapland girl, is beautiful and cute...but she was like a younger sister, and even though she was a scumbag, she got a scumbag. "We can change things, but... I'm glad we met my brother again. We'll be together forever." A story of the pure love and creampies between the two of them, as if to meet Rei's request, as if to close the gap between them with creampies.
