Tatiana is learning for her RN exam. She has a hard time with the muscles. The pictures in the book don't really help. She needs something in 3D - or live. Luckily, her step-son is just coming home. She calls him over.She asks him to take off his shirt and lower his pants. He is a good boy and does what he is told. Tatiana locates the different muscles on his body. One muscle is located a bit too close to his crotch for comfort. Tatiana suddenly feels something long and hard touching her hand. She realizes that her step-son just got hard. The good mammy she is, she blames it on herself. Her husband usually goes when she scratches his balls. She tries it on her step-son. It does not work. He just gets bigger. Absent minded, she touches his hard cock and admires how big her step-son has become. In wonderment, she keeps stroking his cock, until he explodes and shoots his jizz all over her top. Oh well, he's got his relief, she's got her anatomy lesson straight.
