SSIS-492 "Arrogant and distrustful of men..." I lusted after her tsundere younger sister and kept secretly fucking her. The lowest of the low, me. Naruha Sakai

I, who am dating a cute girl, went to her house for the first time and encountered her younger sister 'Naruha-chan,' who is in her rebellious phase and looks at me with cold eyes...! Her indifferent attitude and even cuter face made me excited. Unable to suppress my erection, I touched her beautiful body and did a wicked thing while she was away... However, the tsuntsun little sister who initially resisted eventually became hooked on my dick!? The sister who started seeking our bodies to overlap began to act adorably!
