This production was requested by a client who frequents a gym, targeting the largest-sized breasts ever featured in our past works. Just seeing the photos was enough to shock anyone with their sheer size—making it utterly impossible to conceal them while working out. With gym-related voyeurism becoming a growing social issue, the client immediately enrolled in a personal training program and witnessed firsthand how every male member, including trainers, became obsessed with her massive tits. Hidden cameras were planted in the changing room, capturing shocking footage of her cleavage revealed in stunning detail. The client also attempted stalking and covert filming on trains, brushing against her arm while sitting beside her, pretending to accidentally peek at her chest with a reluctant expression. Later, he followed her home and secretly filmed inside her residence. On the day of the act, the client met her at her nearest station and headed to her place. A duplicate key had already been made in advance, and his heart pounded uncontrollably with anticipation of indulging in her huge breasts. The footage includes various scenes: touching her breasts over clothes to feel their softness, lifting her pajamas to peek at her lower breasts, groping her ass, sniffing her panties, fondling her tits, tongue kiss, removing her panties, spreading her pussy open, blowjob, fingering, bareback penetration, missionary position, spooning position, face-to-face seated position, observing her anus opening, cowgirl position, creampie, second round, face-sitting deep throat, and facial/bukkake.
