"I'm a nymphomaniac, and my boyfriend broke up with me, so please- just help me"
"Really? You can not be serious right now"
"I'm serious, I need a dick inside me right now or I'm going to go crazy"
"You want me to just..."
"Yes, just fuck me"
"Al... Alright"
She went over to the kitchen table, pulled down her skirt with intensity, and revealed herself to me. No underwear necessary, she threw her arms onto the table, pussy fully exposed- wet, dripping, and pink-, and practically screamed,
"Just bend me over and just fuck my brains out!"
As she lay there I undid my belt and slid down my pants with a little hesitation, but as she reached behind her and pulled me by the shirt, my libido took over. I threw down my underwear, and held my dick in my hand. The hand that was behind her couldn't wait. I shuffled forward and watched as my sister grabbed me and shoved me into her.
"Aw... Fuckkkkkk" I said as her warmth enveloped me entirely. The feeling of my raging hard-on being surrounded by the inside my sister gave me a rush like no other.
"God fucking damn it, bro, I need this so badly. This... hits... the FUCKING- euh- spot" she said between moans. She grabbed the edges of the table and started to thrust back onto me. Almost without thinking, I began to thrust back into her with a similar rhythm and the pure euphoria was more than anything I had ever felt. She was practically silent, breaths barely escaping her lips, as I began to give her all I could to satisfy her cravings."
"God fuckin- FUCK- god fucking damn it this feels so good"
"Awwww fuckkkkk" was the only response I could give back. My hands grabbing her hips and forcing them back on to me. My sister squealed and began to orgasm. I felt the walls of her tight pussy clamp down on my iron dick and flood it with her lovely juices. She began to slow down, but quickly realized it and wasn't going to stand for it.
"If you don't fucking speed up, I will fuck you every god damn minute of every fucking day"
"Not sure I'd mind that" I muttered back between breaths, and sped up nonetheless. I could feel my own orgasm building and let her know.
"Just fucking cum in me" she continued to say through gasps and moans, "I don't care what happens as long as you're fucking me as hard as you fucking can"
And as if on queue, she began a second orgasm, moaning and wailing, whilst I let out a grunt and my pent up orgasm released itself. Thick ropes of white flew into my sister as her pussy clamped down on me even harder, and she sighed in satisfaction.
"Aw... fuck... That was fucking amazing."
"Yea... fuck..." was my only response while I processed what just happened. She reached down to her pussy, wiped some of my cum into her hand and licked it off, swallowing it.
"Not bad for my little bro... You're gonna have to fuck me later". She gave me a kiss on the lips- tongue included- for a solid few seconds, and waltzed up to her room, leaving me pants-down and free to the world. "If you're getting hard again after that, you can come up to my room and we can go again", and with a wink she was up the stairs.
