That one was nice. I loved the sexy time decorations and Shiori's cute antics. But I think I would have liked more flashbacks and more conscious, adorable flirting than the underwhelmingly wholesome dream segment.
There was a case of a guy who abused his dauther evey night, he claimed he had somnambulism and did it while sleeping. Not related, but this made me remember that case of sexsomnia (lewding while sleeping).
