Older sister does me a favor

The following is 100% fictional!

So I've been attracted to me older sister for a while. She's in college and I'm a senior in high school. She always been really cool with me, like letting me smoke or drink or go to her parties. Me and my sister have always been really good friends. She even sometimes would give me graphic details of her sex life.

But anyways, me and her and some of her friends (all women) went to a party a few weeks ago. We were all in one of her friends van smoking some good weed and drinking a little. But apparently her dealer laced the weed with some exctacy because all of a sudden we all got really horny. The girls were making out, and one of my sisters friends started feeling up my crotch. But then what happened next really surprised me, my sister took off her tank top. I stood there flabbergasted. Her perfect C cup breasts rubbing on her friend (Onika) as she made out with her.

We got out of the car, all women now fully clothed and went into the party. But I saw in the party (dub step blasting, and the room full of smoke) that everyone was nude... and fucking each other. I turned around to ask why I hadn't been told this was an orgy, but my sister and her friends were walking away into a back room.

"Wait, what about your brother, David?", Onika said as she turned around stroking her pussy.

"oh he's coming with us", my sister said, her eyes fixated on mine. Her blonde messy hair half covering her face and sexy grin. "There's no doubt".

We walked into the room and started finding fuck buddies. Onika hastily picked me, and I had no objection. She pulled off her shirt. She wasn't wearing a bra. She grabbed me by the hair and brought me to her chest. I started licking and sucking her nipples tenderly. She then proceeded to take of MY shirt. Then she started un buckling my pants and took out my already hard, six and a half inch cock. She started giving me one of the better blow jobs I've ever had.

But then my eyes locked with someone else's, across the room... my sister.

She began walking towards me with an intense look on her face. She reached me and Onika and said, "Onika, my turn".

"Oooooh kinky" Onika said.

My sister stared at me for what felt like a life time, until she grabbed both of my hands and brought them up to her perfect, smooth, young breasts.

"Do you like your sisters tits?" she whispered in a sexy, harsh tone.

"Oh hell yes I do".

"Of course you do. You make me so wet." she responded in a drunk and slurred tone. She then forced me back into my chair, knelt down, and without warning shoved my cock deep into the back of her throat.

"Oh shit" I said. It felt like Nothing I'd ever felt before. Her soft mouth combined with the weed and extacy. I couldn't explain it. She kept my dick in her throat for what felt like twenty seconds. She pulled out and gestured for me to get on the floor and for Onika to come over.

My sister (Olivia) came and layer down on top of me in the 69 pose. Her perfect, toned ass and pussy right in my face, her toned abs and tits on stomach. I started eating her out as she began sucking me off and we both were moaning in pleasure. Onika pushed my legs up and back and started licking and sucking on my balls. With Olivia on my dick and Onika on my balls it was inexplicable.

"Awwww shiit Olivia, you guys are amazing!" I groaned.

Then Onika started giving me a rim job. I don't know why but it was an explosion of sexual pleasure. With the drugs, dubstep, and sex I couldn't help it. I said,

"I'm gonna cum!"

They stopped and got on their knees side by side, sticking their tongues out.OH. MY. GOD. My sister and her friend wanted me to blow my load all over their faces. I hastily got up and started jacking my self off right in front of them as they both massaged me lower balls. I came allllll over their faces, they licked their lips and looked up at me with the sexiest eyes I've ever seen. They started making out with the cum on their mouths.

Without a doubt, the best party I've ever been to.
