He and his older brother's girlfriend were having sex under the covers, trying to avoid being discovered. Their large breasts overlapped, pressing against each other as he thrust and ejaculated repeatedly. (Hitomi PPPD-976)

My older brother's girlfriend has enormous breasts. Her perfectly round breasts and cleavage are so alluring they make me want to masturbate in my room, but I never expected to be spied on… The reason I masturbate is because of her, and my older brother isn't here… so this is my chance? I take my older brother's girlfriend under the covers and silently NTR her. I don't know if I've been holding back for a long time, but her nipples are already erect and penetration is possible. I use her enormous breasts, enough to make my penis disappear, to ejaculate inside her. I press down on her suffocatingly large breasts to force my thrusts, ejaculating repeatedly with my older brother so close.
