MIDE-658 The little sister of my tsundere girlfriend is surprisingly deredere to me!? My little devil sister, Mia Nanase, who provokes me with all her might even though my girlfriend is right next to me.

Recently, her little sister has started to get attached to me. She's so cute and keeps tempting me, making me all flustered... 'Your boyfriend is so cool, he might be my type' she shows me her panties without her knowing, even touches my dick... When we're alone together she gets all clingy! 'It's okay! She doesn't notice' I secretly open up her pussy and insert it to appeal to her! Unable to resist the little devil's temptation, I've been sneaking in and fucking her multiple times!
