"Sleeping Back Seeding Press", a complete spin-off work of "Cuckold Seeding Press". This work is about her cousin Aya Sasami becoming a tsundere for her favorite older brother, seducing her by swinging her big butt and making vaginal cum shot in her sleeping back. The gap between Aya-chan and the stubborn Aya-chan is so motivating! A must-see for Aya Sasami fans.
