My cousin Ayu-nee-san is a little older than me and has a bright personality. I received a phone call for the first time in a long time... I thought, but suddenly I was at my home for a while! ? "I've been in it together" and rushed into the bathtub! The stimulation is too strong for a virgin. When I masturbated naked with Okazu, I was discovered and lost my virginity and sex! I can't believe Ayu is so lewd... Life under one roof for Ayu and I has begun!
