As the sun sets over the ocean, the siblings lie side by side on their beach towel, enjoying some welldeserved time alone.The wife looks over at her brother with a mischievous glint in her eye, and begins to slowly undo the buttons of her top, revealing her huge, firm tits.The brother watches in amazement as she slides her top off, revealing her naked body beneath.The wife reaches out and grabs her brothers face, pulling him towards her as she leans down to whisper in his ear, Want to see how these titties feel? She guides his head towards her cleavage and starts rubbing his hand over her chest, feeling the weight of her breasts against his skin.He cant help but feel a little bit of trepidation as he reaches out to touch them, knowing that he shouldnt be doing what hes about to do.But the wife isnt about to let him stop her.She grabs hold of his pants and pulls them down, revealing his erect cock beneath.She smiles wickedly as she takes hold of the end of his dick and starts guiding him towards her tits, holding his head still as she leads him to the perfect position.With a rough, grunting sound, the brother sinks deep into the wifes cleavage, starting to fuck her tits in a hard, rough motion.The wife moans loudly as she feels the muscles of his cock moving against hers, the pleasure building up inside of her.The more he fucks her tits, the more she wants him to keep going.After a few minutes of hard fucking, the brother finally pulls out of her cleavage, gasping for breath as he struggles to regain his composure.The wife reaches up and grabs hold of his face, pulling him close to her as she kisses him deeply, her mouth opening wide as she tastes the sweat and cum on his lips.As they sit there, still caught up in the heat of the moment, the wife turns to her brother with a devious smile, I hope you enjoyed that, because I could do it again any time.And with that, she stands up and starts walking away, leaving the brother behind, wondering what he just got himself into.
