Jeff's sister spent about 30 minutes doing homework all while Jeff lay by the breast of his sister in pure panic. After Jeff's sister finished her work, she hopped up from her desk in her room and strolled over to her bed her breasts jiggling and bouncing making Jeff, hard and erect. She pulled him out of her bra and placed Jeff on the bed. He got a front row seat to the show of a century. His sister stripped each piece of clothing off her voluptuous body, Jeff could see it all, Her huge natural tits, Her round bouncy ass, and most importantly, Her dripping wet Pussy. Jeff's panic turned to erotic excitement as his sister approached him. "Let's have some fun, shall we?" His sister laid down on the bed, grabbing the toy that was his brother and began rubbing the tip along her pink, wet, lips teasing Jeff. She began to push him in and moan as he entered her juicy chasm. The siblings were in bliss as Jeff's sister sped up her pace. Moaning like a whore she used Jeff at lightning speeds bringing both siblings erotic pleasure. She made Jeff point upward as she straddled the cock with fervent sexual desire. She rode that cock hard, her tits bouncing and jiggling up and down and up and down. Soon the moans grew louder as the sister approached climax. With one shove her juicy cunt strangled the cock, covering it in it's juices until just then Jeff explodes into his sister, filling her until a small bulge grows near her stomach. Jeff's sister slows her movement to a crawl as cum fills her womb. She grabs the end of Jeff and brings the cum-covered cock to her face. She licks her lips, and just then Jeff knew what would come next.
