See my previous blogs to read, in order, my sex-capades with my little sister. That Fall, before graduation, my little sister came to visit me in college. I told her that she would have to sleep on the sofa, but that I was so excited that she was coming to stay for a week. When she arrived, the first couple of days were nothing out of the ordinary. We shopped for groceries, visited, talked about school.

The next day was sunny, and the girls said that they were going to work on their tans out back that day. I was home until noon, then had classes that afternoon. Before I left, I went out into the back yard to say goodbye. I noticed right away that the neighbor boys were working on a car across the alley, in a garage, right square behind our house. I thought to myself that this was a recipe for disaster - two girls sunning themselves, with 4-5 young guys working in the garage not 50 feet away. My girlfriend already had her top untied, but still covering her breasts as I left. We had fantasized about letting those guys all fuck her in a gang-bang, many times, when we would have sex, and I told her that I would love it if we could do that before we moved.

When I got home, they were inside, and there was a lot of giggling between them. "Allright, what's up with you two?" I queried. They told me that after I had left, my girlfriend removed her top. The guys were trying to work, but couldn't stop stealing glances, and then my sister took off her top. The guys, they said, kept rubbing at their cocks, trying to work, and trying to not be so obvious that they were looking at the girls bare breasts the whole time. "Hmmm," I thought, "maybe tomorrow you should give them more to look at!!" I was hopefully teasing!

The next day, the sun was back out, and so were the girls. This time, they went OUT topless, and laid on their tanning beds, breasts again in full view. The guys were so excited to see them, they said, that one guy obviously came in his pants. After awhile, my girlfriend untied her bottom bikini. My sister was watching, and when the time was right, she grabbed the bikini bottom and tossed it at the guys in the garage! The girls then "wrestled" around as my girlfriend ripped off my sisters bikini bottom as well, and walked it to the back wire fence, within 10 feet of the guys, who were cheering them on!

Not to be outdone, my little sister pushed my girlfriend up against the fence and told the guys to grope her tits and pussy. My girlfriend didn't object at all, and they told me that they guys each got to suck on her nipples and finger her wet cunt. It sounded like my little sister got in on the action as well. That night, my girlfriend told me to suck on her tits like those guys had done. I barely got inside her before my cock exploded, and creampied her cunt.

The next morning, she awoke really horny. "What are you up to today?" I asked. It was Friday, and my sister was leaving the next morning. "Nothing." she said. "We're staying inside today." It was already raining and overcast outside. "Fuck me and cum inside me before you leave for class. I want your sticky cum all over my pussy and clit." She didn't have to ask me twice, and after thinking about the neighbor guys sucking her tits, I cummed a huge load of cum on her pussy and inside her, and then I had to hurry off to class.

That night she told me what she did to my little sister after I had left.

I guess my sister come into the bedroom to use the bathroom (the only one in the apartment), and my girlfriend was lying there, naked, with a huge cum load on her pussy. "Hey, where are you going?" she asked my sister. "To the bathroom, you slut!" my sister teased. "No you're not, you little bitch! Get over here and lick this cum off my pussy! NOW!!" My sister tried to get down between her legs, when she yelled, "Not like that, you stupid bitch, 69-me, with your cunt in my face! "I have to pee so bad!" my sister stammered. "Fuck you and your pee, I'm going to lick your cunt while you eat cum out of me, and you'd better not pee in my face!" She said my sister licked and sucked her cunt like it was her last meal, and she licked my sister's clit with a frenzy. It was inevitable, that as my sister got close to orgasm, she started giggling, and peeing all over my girlfriend's face.

My girlfriend tasted and swallowed her pee, as she rubbed her face all over that cute little cunt. With pee still dripping out of her cunt hole, my girlfriend grabbed my sister's ass and licked and probed her asshole with her tongue and nose. "Yeah, you lick my butthole, you bitch!" my little sister directed. "Keep going, I didn't tell you to stop!" she yelled. Finally, my girlfriend was so turned on that she exploded in her own orgasm, and peed herself. They both collapsed on the bed, exhausted.

After awhile, my little sister picked up her phone and was looking at a porn site. "What are you doing?" my girlfriend asked. "Are you looking at porn?" "Yes," my sister said, "what's it to you? bitch." "Ha, you're stupid." my girlfriend said. With that, my little sister aimed the camera at my girlfriend, snapped a pic, and posted it to the porn site. "There you bitch, now everyone can look at your dirty little cunt!" "Let me see that!" my girlfriend said, taking the phone. "OMG, there's already been 12 people look at it!" my girlfriend said. "You'd better delete it, you little bitch!" As my girlfriend was saying that, my little sister was taking video of my nude girlfriend, with piss in her hair, and dirty from lesbian sex, and quickly posted it. "Lay down and spread your legs, I'm going to take a bunch of pictures of you naked, and expose your dirty tits and cunt and asshole to everyone!" As my girlfriend laid back and spread her legs, she said, "You'd better not!" My little sister posted about 100 pics and a couple of videos to a huge porn site, that was getting nearly 500 hits an hour. The next morning, as my sister was leaving, she said goodbye, and said, "Tell your little slut that she's now a porn-star!!!" and giggled as she got into her car and left. "What's she talking about?" I asked. "I don't know," my girlfriend said, "She's a slut. I'll tell you all about it some day!"
