When an older brother who likes eroge games signs up for a younger sister catering service, the cute Rika-chan shows up, saying, "Hey, big brother! Let's have a good time together with Rika!" Rika-chan is a completely Kokoro younger sister who will do anything her older brother says, and she gives him a French kiss and a creampie in cowgirl position! They get cozy and kiss while shopping together! After eating together, she sucks his dick right away! Bonus of squirting! After enjoying the game together, she masturbates while remembering her older brother's scent! At the end, they have a sweaty, lovey-dovey creampie sex!
