The Thin Line Between Love and Hate

You don't know why you did it. You never hated your sister more then in that moment. But something possessed you; something **** you to go for it. In one motion you leaned forward, grabbed the back of your sister's head, and gave her a deep, hard kiss.

Your sister didn't fight back. She knew she was already in trouble for going off on you. There was no telling what mom would do if she rejected your advance. So she just laid there, motionless, while you passionately kissed her. Her not being "involved" didn't detour your enjoyment one bit. You never kissed a girl before. In your wildest dreams you never thought your first kiss would be with your gorgeous sister. Yet here you were, naked on top of your sister who looked just like she did at Senior Prom. You had your tongue halfway down her throat.

After about five minutes of her not responding, she lightly wrapped her arms around you. A few minutes later, she re-positioned herself so that you were between her legs. Not long after that you found her tongue entering your mouth. Your eyes shot open at the realization that you were actually making out with your sister.

You kissed each other like animals. Your lips pressed against hers, your tongues flicking against each other. You reached down and grabbed her tit as you explored her mouth. She wrapped her leg around your back and pressed your body against hers. After a solid 20 minutes of making out you pulled away. Your eyes locked with your sister. She didn't say anything, but her eyes told you what to do.

You moved down to her chest. You began sucking on one tit as you roughly groped the other. "Oh fuck" she repeatedly moaned. You had sucked her tit on the video yesterday, and at breakfast today, but she didn't respond like this. You made your way down to her pussy and began to lick. She threw her head back in ecstasy. Her moaning got louder and louder as she grinded her hips against your face. You sat up, grabbed your dick, and plunged it into your sister's wet pussy.

You each shrieked with delight as your cock penetrated her tight vagina. You began sawing in and out, staring at the waves of pleasure hitting your sister's face. She began to yell. "Oh yes baby. Your cock feels so fucking good baby. God I need you inside me you animal!" You yell back at her. "Who am I bitch? Who am I?" She responds, "Oh John, you're a fucking stud. You know how to fuck!"

As you continue to saw in and out of your sister, you reach down and smack her tit as hard as you can. "Wrong answer bitch, Who am I? Who am I?" She looks confused for a second, then smiles from ear to ear. "You're my little brother and you are fucking your big sister's pussy. Oh god little brother, you know what your big sister wants. You know how to fuck your family you goddamn stud!!"

As you slowly approached your climax, you let you a stream of consciousness. "I can't believe I'm fucking my big sis. I've got the hottest sister in the world. Every guy wants to fuck my sister's pussy but she wants her little brother to do it." Your sister stops moaning for a bit and smiles from ear to ear. She then willingly whispers something she almost got sick at the thought of saying yesterday. "I want you to fuck a baby into me little brother."

Hearing those words you climax into your sister's pussy. The feeling of your cum between her legs sends Andrea into a body twisting orgasm. You collapse beside her in bed, unsure of what actually just happened.
