Your little sister Ruby is such a sweet, innocent 16 year old that loves reading books and being the best in her classes. One day you are coming back home and going to Ruby's room to chill with her and help her with her homework, when you see a skinny popular guy named Jack in her year pinning her down to the bed and kissing her hard. They don't notice you yet, Ruby looking up at Jack with large submissive doe eyes. Her petite slender hands run over his bare skinny chest, lust in her magpie shining eyes.

Ruby : "Jack, please... touch me more." Ruby begs, mewling as Jack teases her touching her in all the places close to the sweet spots. Jack grins, his smug jock like expression making you even more pissed off and protective of your sister.
