Fuck Britney now, deal with the rest of your family next...

Jessica doesn’t even seem to hear you, instead her free hand strays down into her lap and you watch her arm move as she begins to finger her own pussy under the table. You turn back to Britney who has begun to increase the pace of her movements in your lap.

“Mmmm little bro,” She moans softly “You cock is filling me inside… I never knew… you had such an… amazing dick!”

You reach out and grab hold of her bouncing tits, you bring her forward and begin sucking hard on them. Britney moans deeply and begins thrusting herself eagerly onto your cock. The feel of your sisters warm snatch enveloping your manhood send waves of pleasure up your spine and you begin moving your own hips up to meet each thrust. Britney throws back her head begins to cry out each time you bury yourself in her soft womb.

“Oh yes! Yes John YES! Fuck big sister’s pussy, Fuck me hard!” She cries as she begins bouncing herself faster in your lap.

You release her mounds and grab her head, bringing her mouth to yours. Her tongue slides between your lips hungrily seeking yours, and you respond eagerly. Fucking your own sister feels incredible you think. She abruptly breaks off the kiss and leans into you, grabbing the back of the seat for support. Her hips grind into your lap as she tries to bury your cock deeper inside pussy and animal groans escape her lips as she fucks you desperately seeking climax. You feel her womanhood spasm and Britney begins panting heavily.

“Oh god, I’m cumming! Little brother is fucking me and making me cum!” She moans between heavy breaths “God John, make me cum! Make me cum hard!”

You don’t hear her, the feeling of your sister’s snatch tightening around your cock as she cums has set your body on fire. Your balls tighten and you grab Britney’s hips and begin pounding up into her as hard and fast as you can. She begins to shudder as one orgasm follows another as you **** yourself into her again and again until you can’t take it any longer either.

“I’m cumming!” you cry from between gritted teeth, as your cock explodes inside of her. You both cry out one last time as the pleasure overwhelms you and Britney sags on top of you gasping for air. You run your hands over her soft smooth skin for a few moments, basking in the afterglow of cumming inside your own sister.

“Jesus lil bro,” Britney says between heavy breaths “I’ve never… No man has ever…” She seems lost for words but her message is clear, she’s yours now and always will be.

You look over her shoulder at Jessica who is still sitting at the table fingering herself eagerly, and listen to the sound of running water upstairs from your mothers shower.
