A siscon older brother who loves idols registers for a sister catering service... and finds himself face-to-face with an ultra-beautiful girl with twintails and an anime voice! "Thanks for accessing me, brother. Today, let's do all sorts of naughty things with Kurumi!" Her flawless skin and bouncy tits are irresistible! She straddles her brother and immediately starts sucking his erect dick. In return, she gives him a pink-painted pussy that's so wet it glistens as she inserts his dick and drools while riding him. After enjoying snacks and games, Kurumi feeds her brother something from her mouth... "Taking you to Kurumi's world..." When the brother wakes up, he finds Kurumi transformed into a succubus, the complete opposite of her previous innocent self! Excited and unable to control his erection, the brother thrusts his dick into Kurumi's pussy repeatedly, making her cum profusely. "Cum inside me, brother!" "Now, fuck me from behind!" He cums repeatedly, overwhelmed with pleasure. Her pussy is now soaked in her brother's sperm!
