ROYD-305 — My Older Sister Is Plain And Reserved, But When She Takes Off Her Glasses, She's An Unbelievable Beauty. I Couldn't Resist And Made A Move On Her, And She Let Me Have My First Unprotected Sex With Her, Starting With A Dry Hump And Then Letting Me Cum Inside Her. Forever

My sister-in-law is usually plain and doesn't wear makeup. But I know. I know she's beautiful! I can't help but give advice to my sister when she's struggling with interpersonal relationships. This sparks a rapid improvement in her makeup skills, and she gradually gains confidence in herself. Eventually, she transforms into a stunning beauty with an amazing figure that turns heads wherever she goes. But as her brother, he can't keep quiet. One night when their parents are out, he impulsively confesses his feelings, but she refuses, citing their sibling relationship. "You don't have to put it in, just rub it against me..." And so, the two agree to only rub against each other. But the two young people can't be satisfied with just rubbing against each other, and they end up crossing the line. They have incredibly pleasurable unprotected sex again and again. At first, their relationship is purely physical, but gradually their hearts connect, and they become lovers.
