Author's note: This chapter is a bit lengthy as it wraps up the "Getting caught" Story arc which I didn't want to carry into another chapter. There is also more of Mark and Megan's back ground that will play into the series finale. Also a warning: there is a short flashback sequence from Megan's past that may be a bit much for some readers if you are on the squeamish side you may want to skim or skip that part. Once again thank you all for your votes and feedback! Lovecraft68

Oh Megan you are a nasty girl, I thought as I found myself once again squatting on the bathroom floor watching my brother and Krissy through the missing doorknob. This time it was different for a couple of reasons; one Mark knew I was watching and two; he was being far from gentle with his little Krissy. Mark had already stripped her naked, all but tearing her blouse off of her and forcing her to her knees by her shoulders, had whipped his cock out and had told her to suck it like she knew what she was doing for once.
Krissy had whimpered out something then grabbing my brothers massive prick started slowly sucking on it, barely going down halfway before taking it back out. Mark let her do this several times then looked straight at the bathroom door winked and asked Krissy if that was the best she could do. Without waiting for an answer Mark grabbed the back of her head and shoved his cock all the way down her throat. Krissy tried to push back, but when she did Mark grabbed her hands. After securing both of Krissy's wrists in one of his Mark held her arms over her head. He grabbed a handful of her long hair started brutally fucking her mouth, pulling his huge cock all the way out before driving it back in.
As I watched, my fingers were dancing across my clit and my right hand was inside my shirt playing with my nipple. Krissy began whining and whimpering, even from ten feet away I could see the tears coming down her cheeks from gagging on my brother's dick. Mark asked her if she liked it like that; at first she shook her head until he reached down and roughly pinched her nipple, the next time he asked she nodded and by then seemed to be doing a better job of taking it all the way. Mark stepped back pulling his cock from her mouth and let her hands go. As Krissy panted for breath as Mark sat on the bed and grabbing her hands, he laid on his back pulling her into a standing position.
Bending over Krissy grabbed my brother's cock and started sucking on it again, as she did her ass was pointed directly at me. Krissy's thighs were a bit on the thick side but I could still see her pretty little pussy winking at me from between them. I let out a soft sigh as I noticed her pussy was glistening meaning she had been quite turned on by my brother's raping of her mouth. Mark told her to stop sucking and get on his fucking cock. Krissy obediently climbed up onto the bed and straddling Mark's hips reached back behind her.
I let out a louder moan as I watched Krissy wrap her hand around my brother's cock and guide it into her tight little pussy. I watched, deliberately slowing my thumb down so I wouldn't cum yet, as she slowly lowered herself onto it. Krissy started to slide back and forth as she leaned over so that her tits were swinging in my brother's face. Mark's arms came around and grabbing Krissy's waist pulled her down on top of him then held her there as he started lifting his hips off the bed slamming his cock deep up inside of her.
Krissy was letting out little yips of pleasure and I was letting out some noises of my own as I watched Mark's glistening cock slide in and out of Krissy's pussy. As if reading my mind Mark slid his hands from her hips and grabbing her ass cheeks spread them open giving me an even better view of his cock pounding Krissy's sweet little slit.
Mark said something and Krissy swung her leg over his hips so he could move. Rather than get up Mark simply turned sideways and had her get back on top. I knew this was purely for my benefit as now I could see Krissy's big beautiful tits bouncing as she started riding my brother faster and harder. Krissy let out a sharp cry as Mark reached up and pinched her nipples.
I was breathing heavier but didn't want to cum yet, I knew the best was yet to come and sure enough my brother didn't disappoint me. Telling Krissy to get off of him he made her get on her knees facing the bathroom door. As I watched, my fingers hovering around my clit in anticipation, Mark took his huge cock and rubbed it along Krissy's ass, even spanking it on there before taking it and in one thrust drove it in to the hilt.
Krissy's eyes widened and she cried out as my brother started hammering his cock into her pussy hard and fast. My fingers sped up as Krissy was making noises that were a mix of pleasure and pain every time Mark slammed his cock into her. Krissy tried to move forward to make it easier but my brother grabbed her hips and holding her still started fucking her even harder.
"Oh god Mark!" She cried out. "Oh that's so deep! Oh!!"
Mark let go of her hips and in one smooth motion leaned forward, grabbed Krissy's wrists and yanked her arms back. Krissy's face went down into the bed which caused her ass to rise up. Still driving his cock into her Mark took her arms and grabbing her wrists with one hand pinned them behind her back.
With his free hand Mark grabbed a handful of her hair and pulled her head up by it.
"Oww!" Krissy yelped.
"Yeah you like that don't you?" He asked.
"Oh yes!" Krissy exclaimed then yelped as Mark pulled her hair harder.
"You know that's not what I want to hear."
"I don't want to play like that Mark I...Oh Fuck!!!"
That last exclamation came out as Mark, still holding her by her wrists and hair, started fucking the shit out of her as hard and fast as he could.
"Just tell me Krissy," My brother said. "Or maybe I should just shove it back down your throat?"
I saw Krissy swallow hard then suddenly started yelling;
"Oh please stop Mark!" Oh please stop! You're hurting me! It's too big oh please!"
As Krissy continued to beg I started moving my fingers even faster, spurred on not only by her cries but by the look on my brother's face. Mark loved it. His eyes were bright and he had an evil smile on his face as he continued to absolutely hammer away at Krissy's poor little pussy.
Mark and I weren't the only ones enjoying it. Krissy's expression had also changed from one of nervousness to a look of pure lust. Oh look at little Krissy being a naughty girl! Feeling my orgasm beginning to build I once again slowed down trying to time it with Mark's. After several more savage pumps that had Krissy all but screaming. Mark yanked his cock out and squeezing it at the base rolled Krissy over and sliding up over her face told her to open her mouth.
"Oh please don't! I don't like that I... Umm!"
Krissy's cries turned into a gurgle as my brother shot his massive load straight into her mouth. Krissy tried to turn her head but Mark grabbed her hair and held her still as he continued to jerk his cock off in her face spraying his come all over her cheeks and mouth. I bit my lip hard as my own orgasm sent waves of pleasure crashing through me. As I watched Mark wipe his cock off across Krissy's lips I furiously drove my hips into my fingers pumping them in and out of my pussy.
Mark sat next to Krissy on the bed and after saying something I didn't catch(,) leaned over and kissed her on the cheek. As the last of my orgasm flowed through me I sank to my knees breathing hard. Mark grabbed a towel the floor and gently wiped Krissy's face off. After a minute she sat up and he hugged her. Krissy looked like she wanted to be upset, but Mark kissed her softly on the lips and told her he loved her. Krissy's eyes softened and she told him she loved him to. I watched for a couple of more minutes as they stretched out on the bed and Mark put his arm around her.
I got up at that point and returned to my lonely bed. I sighed as I closed my eyes wishing it were me that Mark was holding in his bed. After awhile I was still awake when I heard a soft knock on the door. Was that Dad snooping again trying to catch us? I sat up and as the knock was repeated I realized it was the bathroom door. I smiled, maybe Mark couldn't sleep and he was going to fuck me, treat me like a little whore, like he did Krissy, and make me suck her off his cock again.
"Come in." I called softly.
I was wearing a pink tank top and matching panties and as the door opened I started to lift the tank top up so the first thing Mark would see was his sister's perfect tits with her nipples erect and eagerly awaiting his tongue. I had the shirt all but off when Krissy came through the door. I quickly lowered the shirt already feeling myself blushing. What the hell was I going to say? "Oh I had my tits out because I thought you were my brother?"
Fortunately as Krissy had come in she had her head turned over her shoulder as if looking back into Mark's room. By the time she turned I had the shirt back down although there was really nothing I could do about my nipples poking through the flimsy material except cross my arms.
"Hi, can I come in?" Krissy asked.
"Um sure," I said.
I leaned over and turned on the small lamp next to the bed and watched as Krissy came over to sit next to me. Krissy had her long hair down and was wearing Mark's black robe. I noticed the robe was tied loosely and I could see the swelling of her breasts.
"You and Mark have a fight or something?" I asked her.
"No," As she replied I noticed she was looking down.
I followed her gaze and realized that I had kicked the covers off and was just in my panties. I reached down to grab the sheet but stopped as I noticed Krissy's eyes were fixed directly between my legs. I glanced down and saw that, because I had one leg on the floor and the other bent up, my legs were open and the thin crotch of the panties had ridden to the side and half of my pussy was exposed.
I should have been embarrassed and closed my legs or at least pulled up the sheet, but instead felt my heart beat pick up in excitement. I became even more excited as I realized that she could definitely see that the crotch of the pink panties was damp from where I had just played with myself. I looked back up in time to see Krissy's eyes work their way up and as they did I removed my arms from my chest and sure enough her eyes quickly found my nipples.
Taking advantage of her staring at me I let my eyes wander across her body. I started at her bare feet with their purple toe nails then let them slide up her leg all the way to where the bottom of the robe had fallen open to give me a great view of the inside of her upper thigh. The top of the robe had come undone even more as she sat and from the side I could see her entire right tit down to the rose colored skin around her nipple. I returned my gaze to Krissy's face and felt myself getting more excited as not only was she still staring at my tits but her lips were parted and I could see she was breathing heavier.
I found myself once again staring at her full lips that were so much like my own and, as I had the other night, wanted badly to taste them. The thought that those lips had not a half hour ago been covered in my brothers cum added to that desire. Finally I broke the silence.
"Krissy?"
Krissy had been so intent on my tits that she jumped at the sound of my voice and blinked a couple of times before looking up at me with those adorable big brown eyes.
"Oh sorry, I was just..." She shrugged and began to blush.
