Tayama Daisuke

Little step-brother who is one fugly pervert.

He has the personality of a nasty pervert and takes snatching his big sister's underwear for granted. He engages in peeping, taking secret photos and rummaging through the trash bin for feminine hygiene items. A scumbag of unrestrained horniness, as one might call him.

He possesses a penis well above the average length. It can reach Saki's cervix with ease.
