Nala Brooks is only allowed to suck his dick

So why did Nala Brooks burst into her stepbrother's bedroom (in just her lingerie)? To tell him that that mom and dad aren't home and they won't be for three days. Why is that relevant? Well, Nala wants to fuck! He tells her he can only suck his dick and Nala, Nala is fine with that..for now. You know she will convince him to fuck later. Those sucking skills alone will be enough to do that!
