Cyndi gasped as his cock stretched into her tight hole. But Al got it all in, and once her asshole was filled with his cock it was time to fill her other hole. Doug slithered in between Cyndi's spread legs. She had her legs stretched out, and was bent at the waist with her ass impaled on Al's shaft. Cyndi's eyes stayed closed as Al held still.
Doug got between her legs and slid his long pole into her cunt.
Cyndi began to moan and beg immediately. The two guys began fucking her in rhythm, boning her hard up the ass as she took it gratefully. Cyndi rubbed her cum-smeared tits against Doug, who was kissing her mouth deeply. Al, overcome by the great feeling of having his cock in Cyndi's tight asshole, seemed to be lying back and enjoying it as Doug's cock thrusts dragged Cyndi's body up and down. That way, Cyndi's ass dragged Doug's cock in and out of her.
As I watched them in the camera, I had my cock in my hand and was slowly working it up and down. It sure did look tasty-my sister had one hole that wasn't filled with a cock. I wondered… nah!
They fucked crazily like that for a little while and then Cyndi moaned out a demand.
"Switch places! I want Doug to cum in my asshole and Al, I want your cock in my pussy!"
Obediently, the two guys pulled out of Cyndi. They positioned her on her knees so that she was set up doggy-style. Al got underneath her and slid his erect member into her cunt, while Doug stood behind her with his knees on the side of the bed and put his cock into Cyndi's tight asshole. They fucked her that way, and I could see the silhouette in the camera-it looked good. And Cyndi's mouth was wide open and gasping.
That did it. There wasn't anything else to be done. Leaving the camera on, I left Cyndi's room and ran up the hall.
They'd left the door open. I heard three gasps of surprise, and the two guys moved to pull out of Cyndi as they saw me. But Cyndi leaned forward, keeping Al in her cunt, and reached back to grip Doug's prick in her asshole. Meanwhile, she smiled at me and beckoned me with her lips.
I slipped out of the robe and moved naked toward the bed. Cyndi parted her lips wide, begging me to put it in. I took my cock in my hand and knelt in front of her. Al was short enough that her head extended over his and there was plenty of room for me on the bed. Cyndi leaned down and opened wide as the two cocks seethed into her.
"I'm so glad you could make it," she gasped just before she went into action on my prick.
Cyndi pressed her red lips around the head of my cock. She sucked it slowly into her mouth, forcing it as deep as it would go, until the thick head pressed into the soft flesh at the back of her throat. Then she forced it deeper, deep-throating me. She started shoving my cock in and out of her mouth, swallowing crazily as she pumped me to satisfaction. Meanwhile, the other two guys in the room were also inside her. I looked down at Cyndi and saw her entirely filled with cock-mouth, cunt, and asshole! Her hands were also filled. One curved around the base of my prick, while she reached down with the other and felt the twin shafts of her lovers' organs plunging into her. I was on the verge of cumming already, and I reached down to stroke Cyndi's cumcovered face as it came down rhythmically on my cock.
Cyndi licked down, sliding my shaft out of her mouth, and began to cover my balls in wet strokes. She lapped and sucked at my balls, taking them into her mouth and caressing them with her lips. Then she licked her way up again and plunged her mouth down over the length of my cock, intent on making me cum immediately.
I heard loud groans from underneath me and the other end of my sister as Doug and Al came simultaneously. Cyndi went crazy as she ground her whole body against the two men, taking Doug and Al into her asshole and cunt repeatedly. Meanwhile, she sucked on my cock harder as they came inside her. She tugged forward on their cocks, yanking them out of her, as they took hold of their own cocks.
Cyndi got her fingers round Doug's and began to jerk him off all over her buttocks. Streams of jizz flew over her back and down her thighs.
Then Al shot another load from underneath, covering Cyndi's tits.
Meanwhile, Cyndi sucked me off and I let out a wild groan of ecstasy, ready to cum myself. She sucked harder, faster-after all, I was her only brother. She didn't pull me out as she realized that I was going to climax.
Instead, Cyndi suckled at my cock, intent on getting all of my jizz. I guess that was to tell me that she loved me more than the others. I gave out with a moan of pleasure and felt my cock erupting with semen.
A thick line streamed down Cyndi's throat and she let out a wet whimper of desire. She swallowed eagerly and coaxed more out of me, sucking at it as I came. Finally, as Doug and Al watched, Cyndi got the last of my fluid and slid my soft cock out of her mouth.
I chuckled, backing away from my sister. She looked a pretty picture with two guys astride her, and now I was on tape with them as part of the whole sordid endeavor. I wondered what it looked like.
"I didn't think you'd ever show up," panted Cyndi through her cumflecked lips. "But here you are!"
"And just in time," I said. "You kids finish up in here. I'm going to go take a shower."
I walked into the hall, stark naked. As I closed the door, I saw Doug leaning down to lick Cyndi's asshole. She was willingly rejoining the threesome, letting them fuck her. I couldn't believe it. I'd just taken part in a gang-bang on my sister! I'd just used her like she was some kinky sex toy, the same way Doug and Al used her. It was a sordid mess, even ignoring all the cum on the bed and on my sister. It rather disgusted me.
The thing I hate about my own sex is that they toss sluts around like they're something to be used. Fucking my sister was one thing. Filming her getting fucked was all right. Helping her get used by three guys at once, one of them her brother, was another thing entirely and I felt like shit. I wished I'd been happy just watching her. But Cyndi had her hunger for cock like any normal woman, and she had to go get it. Her immediate family members just wouldn't do.
I went out into the yard and dove into the pool, rinsing myself off of all that cum and sweat. I felt pretty disgusting, and the ice-cold water didn't do much to liven me up. But oh well, I swam there in the darkness, staring up at the stars, and asked myself just how many pricks could my sister need. A lot, evidently. Maybe too many!
Then again, maybe not enough. For her, at least!
Chapter 8
After my swim, I got a towel out of the closet by the pool and wrapped my nude body in it. I went up to Cyndi's room to wait for her. They were still at it, I saw through the viewfinder… I suspected they would be at it for some time.
I lay down on the bed, feeling my cock get hard again. God damn! That little bitch was the hottest vixen I'd ever had wrapped around my cock.
I never would have suspected that my own sister could be such a whore.
But she was, and she did it quite admirably. She was in there balling two guys at once, and she'd just taken on three-myself included. I had no doubt she'd love to do four. It was unbelievable.
My prick started to bulge and throb as I thought about Cyndi. She was in there with her legs and ass-cheeks spread, and her lips too-God, imagine those lips! I opened up the towel and let my fingers curve around my erect prick. I started to jerk off as I fantasized about Cyndi. I could have popped in to the other room and eased my cock into one of my sister's many orifices, but I preferred to avoid the crowd.
Instead, I thought about having Cyndi all to myself, having her sensuous ass-cheeks curving around my shaft as I fucked her up the ass, or from behind in the cunt doggy-style. Cyndi's tits bounced up and down in my fantasy as I fucked her. I jerked myself off rapidly, and let out a little grunt as I came inside Cyndi's imagined snatch. I'd done it plenty of times-imagining myself fucking my very own sister-before I ever got into Cyndi's panties. Now I was doing it again.
