pressed up against her chin. Karen moaned deeply, then pulled away from Blondie's big cock and gasped out, "Yeah, it's so fuckin' good! Wait, I want you both to fuck me at the same time. I want a cock in my ass and pussy!" The guys looked at each other for a second, then the blonde said, "For real? You wanna get double stuffed?" "Fuck yeah I do!" Karen panted. "Here, lie down on your back." It was as they switched positions that I made my crucial mistake. I was so caught up in the action going on in front of me that I forgot that I was only partially hidden by the bedroom door. As Karen swung around and impaled her wet pussy on Blondie's hard cock, she was facing directly toward the doorway. For just a moment, our eyes locked. She got this huge grin on her face and, still staring directly at me , she shoved herself down and took Blondie's entire cock deep into herself in one motion. Fuck! I was caught! I quickly ducked back completely behind the door, but I knew it was far too late for that. As I stood there, torn between shock and incredible feelings of lust, I heard Karen say, "Mmmm, yeah, now shove your big dick up my tight little asshole! Yeah, fuck both my holes!" This pushed me over the edge. I couldn't take anymore, my cock was so hard I was afraid I was gonna cum in my jeans in another second. I rushed to my room, shutting the door behind me as quietly as I could, I ripped off my clothes in a frenzy and, lying down on the bed completely naked jacked my rock hard ... prick as I continued to listen to my sister getting fucked just down the hall: "Oh yeah, uhhh, that feels so good, so full!

"Me too, shit, it's too fuckin' good. Uuuunh, fuck, I'm gonna cum!!" "Yeah, fuckin cum inside me! Shoot that shit deep in my ass and pussy! Do it!" "MMMM, UNNHHH! Yeah, fuck!!" For a long while everything was quiet except for the sounds of harsh panting and low, ragged breathing. My hand was a blur on my cock by this time, and I felt ready to explode. I froze as I heard the sound of voices in the hallway: "Shit Karen, that was awesome! Thanks a lot!" "Yeah, thanks, that totally rocked!" "Anytime guys. You should come over more often!" The sound of my sister's laughter. "You know we will now for sure! We'll call soon. I wanna get a chance at your sweet ass next time!" "No problem, whenever you want, Gary." Again, her soft chuckle. "Well, we gotta take off, practice this afternoon." "K, see ya later. Call me." "You know it!" Then the fading sound of footsteps on the stairs, the slamming of the front door, and they were gone. Man, I just had to bust a nut. I resumed jacking at a frantic pace. Yeah, so close, I know I'm gonna shoot a huge load, almost there. . . My bedroom door swung open. Karen stood in the doorway, naked, her large nipples rock hard, a slight sheen of perspiration glistening all ...
