Hot and Horny/Jess washes her breasts
You work a good lather with the soap and start rubbing it all over your large firm breasts, making circles with it around your nipples. After a few minutes of this, you decide to wash them your favorite way which is to work the soap in your hands and then just cup and kneed your breasts directly. You cup your hands around the bottoms of your pendulous tits, massaging them gently, and then work your way up to the nipples. At this point, they are as hard as they've ever been, sticking out a good inch like thick tips of pencil eraser. Soon, simply rubbing them isn't doing enough for you and you grasp each one and pull them roughly. You moan loudly, surprising yourself, and feel a gush of juices come from your pussy. Quite clearly, this is the horniest you've ever been.
As you give your nipples a good twist, you realize you haven't been paying attention to the sound of the curtain parting and your brother getting into the shower with you. But, next thing you know, a rough, strong pair of hands reaches from behind your and cups your slick boobs. Your instinct takes over and you let them manipulate them with complete freedom, kneeding and grasping the fresh and then squeezing and twisting your nipples.
Suddenly, you feel something nudge against your ass. You know what it must be but you can't help but explore. As your brothers hands keep twisting and pulling your erect nipples, you reach a hand down to your sodden pussy and give your clit a satisfying rub while reaching the other behind you to find what you expected: you take into your hand your brother's giant, erect cock poking so exquisitely at your firm ass.
