I decide to tell Megan that Becka is the room. I tap her on the shoulder. She pulls herself off my cock. I let silent groan as my cock pulls out of her throat, maybe I should have just ignored my sister. Megan pops her head out from under the covers throwing them to the side revealing both my glistening cock and her dripping pussy and says, "You're turning down the chance to cum down my throat."
"Meg!"
"You must really be in the mood for me to ride you hard tonight."
"Meg, Becka is right over there." I say pointing towards the other bed with one hand, while frantically trying to grab the blanket to cover us back up again.
"Oh my God I'm so sorry! I'm sure the last thing you want is to see your brother having sex."
"Don't worry about it Meg, I don't mind, it was actually kind of hot," my sister says with a dirty little smile on her face.
"Becka!"{if Becka Sex=true} {else} I can't believe she'd say that.{endif}
"What, you two have always been fun to watch."
"What do you mean 'always'?" Meg says, I'm surprised she doesn't sound angry.
"You two were always getting hot and heavy at our house when I was little. And I was a curious little girl. I still remember the first time I saw your big cock bro."
"Becka!," I say{if Becka Sex=true}.{else}, pulling at the blanket trying to cover up.{endif}
"What? It left a big impression on my young little mind. And I do mean big, I didn't have anything to compare it to at the time, but as I watched through the closet doors where I was hiding and saw Meg pull your pants down and this big meaty stick came into view I gasped. I was afraid you would hear me, but you must have had other things on your mind as Meg pushed you back on the bed. Meg you must have been pretty horny, because you jumped up on the bed and straddled my brother."
At this point in the story I realized that Meg was straddling me and that my naked erect cock was resting between her wet pussy lips.
Becka shifted in her seat on the opposite bed, staring at us intently as she recalled that night years ago. She continued, "I knew in theory what was supposed to happen next but I couldn't believe that big cock of yours would actually fit inside Meg. You guys proved it could, I could hear each of you moan as my brother's entire cock was buried deep inside you, I could only imagine what that must have felt like."
As this point Meg grabbed the head of my cock as it rested on my belly. She used it as a handle as she began to slide her hips up and down my rod, coating my shaft with her wetness.
"It was amazing to me that you could just keep slamming that giant rod of my brother's in and out and in and out of your coochie for so long." Becka paused and I realized she was breathing heavily, and one of her hands was in her crotch. "God, that turned me on so much, it turns me on so much now. I.."
Meg, who by now is just dripping on the underside of my shaft as she continues to grind her hips along my length, interrupts Becka and says...
