Karlee Grey‘s stepbro is about to take it to the next level with his girlfriend, but is a bit inexperienced so he hits up his sis for some advice. Shes a naughty thinker, and the first thing she asks is if he has a big dick. She doesnt want a verbal answer either, she wants to see what hes got. After she gets a peek, she cant help but want to rub it. She encourages him not to cum too early, but hes having trouble. Good thing Karlee whipped her tits out to distract him. The next day, stepbro goes to tell Karlee about what happened with his girl. Turns out she teased him, left him with a huge hard on, and didnt even give his cock the slightest touch. Good thing Karlee has been craving more of that stepdick. She offers to help right away, and sucks it good until the last drop. A few days later, stepbros lust for Karlee starts to burn. He sneaks into her room to get a whiff of her panties, but unfortunately gets caught! Karlee kind of freaks out, but when she realizes how big the crush he has on her actually is, it becomes more cute than creepy. Karlee then says the magic words, asking if stepbro just wants to fuck her. Of course thats a yes! These sex driven sibs rock that bed back and fourth like it was going out of style, and give us one beautiful family fueled performance. Karlees huge tits were just begging to get nutted on, and stepbro made sure to leave her one happy camper :).
