Chelsea

"You know what?" You say to your mom, "I didn't get to finish what I started with Chelsea, so I think I'll join her."

"That's what I'm talking about!" Chelsea says, exhuberantly. Your mom pouts as you and Chelsea head to her room, but you aren't worried. She'll relieve her sexual tension by fucking the clerk when she goes to the store or something like that. As you reach Chelsea's room, you pause for a moment at the door. You shake the dust out of your eyes and walk in with her. She curls up on her side and presents her still wet pussy to you. You climb up on the bed with her and take your rick hard cock and glide it into her beautiful pussy. She takes a deep sigh when you enter her. Then you start banging her. Her sighs turn to cries.

"FUCK FUCK FUCK! AH FUCK! YOUR DICK! I LOVE YOUR HUGE MASSIVE DICK! AH FUCK ME! AH FUCK MEEEEEEE! I LOVE IT WHEN YOU FUCK ME! I LOVE IT WHEN YOU SITCK YOUR SHAFT BETWEEN MY THIGHS AND GO TO TOWN! OOH! OOH! OH YEAH! KEEP FUCKIN'! FUCK ME BUBBY! FUCK YOUR BIG SISTER! **** HER SWEET PUSSY! AH!"

You grab her flopping boobs and tumb her nipple with you pound her pussy. With your other free hand, you stick a finger up her asshole.

"OOOH YEAH! YEAH BROTHER! FINGER MY ASS! FINGER IT! UHH!"

You catch her by surprise by pulling out of her vagina, and immediately shoving your dick in her ass. She screams louder.

"WHOA YEAH! OH YEAH! FUCK MY ASS! **** IT! **** ME! I LOVE BEING YOUR FUCK TOY! I LOVE BEING YOUR **** PARTNER! I LOVE IT! BEING A SLUT IS MY LIFE! YOUR MY MAN-WHORE! I'M YOUR SLUT! FUCK MEEEEEEEE!"

Chelsea's ass is loose, no doubt from being penetrated there many times by other men, but that makes it no less enjoyable. Feeling close to cumming, you switch back to her pussy. Chelsea can't stand it anymore and squirts all over you. You continue to fuck her, and explode into her pussy. You pull out and fall on the bed next to her. "That was fun," you say.

"Yeah. Let's fuck again." You are happy to oblige, and spen the next hour banging your sister in multiple positions all over her room.

When you finally leave, you come out just in time to see your younger sister Brittany, come home from school. Brittany is also 18, but a grade younger. Her boobs are a mild B cup, but her ass is out of this world. It's amazing how a girl so small can get an ass that big and be so toned. Brittany looks up and sees you pulling your pants back on. "Skipped school to fuck Chelsea, eh? Could have told me, I would have joined you."

"Sorry Britt, I woke up late."

"So tomorrow morning, when you wake up to me licking your dick, you better fuck me."

"Will do." You finish dressing and grab your keys to head out.
