Z moaned with her as I played with her smooth pussy and she spread her legs open some more. Moving to the side of Z I put some pillows at her back so that she could continue to watch the computer screen, not saying a word. I got on my knees in front of her and with her sitting on the edge of the bed, I had access to her wet pussy.
Back on the screen, Aunt Corrie pulled down moms panties from behind, then bent her over the bed, mom putting a hand on the bed to support herself. Aunt Corrie took moms ass cheeks and spread them open and stuck her tongue right up moms asshole, causing mom to let out a scream, at the same time i took Z's clit and sucked it into my mouth causing her to scream along with mom. Aunt Corrie continued licking moms asshole deep, her face pushed into moms ass cheeks, reaching up with her hand, she slid two fingers into moms clean shaven, wet gash, forcing another scream from my now naked mother.
Z pulled my face into her wet pussy as she couldn't look away from the screen. I slid a finger into her as I sucked on her hardening pink clit and she again screamed in unison with her mother, releasing a flood of juice onto my finger.
Z push my head back, looking into my eyes and said, "Please eat my ass." I smiled and we both jumped up, Z getting on her hands and knees on the bed facing the laptop and I getting behind her. I spread her ass open looking into her asshole that was already wet from her dripping juices, I swear it winked at me. As I heard mom give out another scream I drove my tongue into my sisters ass which forced Z to let out her own scream.
I looked up to see both mom and Zoe on the bed with their ass up in the air, their heads down on the mattress and their partners behind them, licking and diddling their assholes. Aunt Corrie now had both her index fingers in moms ass, pulling her little brown orifice apart, trying to let her sphincter relax and except its fate. I pushed a finger into Z's ass and she pushed back trying to take it all in. I worked on her till I could feel no resistance on my finger. Pulling it out I shoved my tongue back in then pulled back and spit into her asshole. I looked at Z watching her mother being serviced and she had a look on her face that was excited, fearful and pleasurable all at the same time. I slid two fingers into her ass and she sucked them right in. I could feel her doing her best to relax her hole. After a bit I tried to work a third finger in, but was still a bit to tight and I didn't want to hurt her.
I reached into my nightstand and pulled out a jar a petroleum jelly and with a finger applied some into her asshole. Sufficiently lubed, I tried the tree fingers and with a slow push they invaded my sisters ass causing her to moan loudly. I was enjoying playing with my sister when she said. "Bobby, look."
Looking at the screen, Aunt Corrie was on her knees behind my moms upturned ass and was strapping on what appeared to be about a seven inch pink dildo, buckling the little straps on her hips. Zoe turned her head, looking at me and said, "Bobby, when Auntie Corrie enters moms ass, I want you fuck mine." I didn't even ask her if she was sure. I just got up being her and started rubbing my throbbing cock between her ass cheeks. Z reached back and slid two of her fingers into her pussy using her thumb to rub her clit.
I watched as Aunt Corrie stepped in front of mom, took her by her hair and pushed that dildo into mom mouth, saying, "Get it wet, bitch."
I jumped up and came around to Z's face, grabbed her hair, stuck my cock in her mouth and whispered, "Get it wet, bitch." Z worked her fingers faster in her cunt and began coating my cock with her saliva. I took my cue from Aunt Corrie, when she moved back behind mom, I did the same to Z. I watched as that pink dildo was placed at the entrance to moms asshole and I put my cock to Z's ass as she reached back and pulled her cheeks apart like she was watching mom do. As Aunt Corrie started to push into mom, I started to push into Z. Both woman were moaning as they remained still. I pushed slow, but steady and watched as my sisters asshole spread open, the head of my cock slipped in. Z was very still, but didn't pull away. I looked up and saw that pink dildo slide about half way into my mothers ass as she let out a scream of pain and pleasure. With just the head of my cock inside Z, I pushed in, feeling Zoe's ass open for me. I went slow until about half my cock slid in, when Z put a hand back to my hip and held me from going farther, never taking her eyes off her mother. I remained still and put another dab of slick jelly around my cock and Z's opening.
I watched as Aunt Corrie pushed that dildo into my mother as far as it would go, Corrie's pelvis pushed against my moms ass cheeks. Zoe grabbed my hip and pulled me into her as she pushed back into me, taking my whole cock into her ass, letting out a cry as she did. I remained very still, letting her adjust to the invasion as her hand worked her pussy and my balls. Aunt Corrie started moving her rubber member in and out of moms ass, mom showing nothing but bliss on her face as the pings from people donating to moms cam girl site was almost nonstop.
Z said. "I can feel your cock with my fingers."
My cock could feel her sliding in and out of her gapping hole and I started to move. pulling out about half way and then back in as I heard Z grunting like an animal. I was in heaven and doing everything I could think of to hold back. I didn't want to stay in her to long so has not to hurt her and just followed her lead. Z started to push back as I was pushing into her. I could see Aunt Corrie fucking my mom full bore. In and out that dildo went, my mom screaming now, her hips fucking back into Aunt Corrie, as her own hand now three fingers working in and out of her pussy.
Z looked back at me, her eyes glazed over and screamed, "Fuck my ass, brother." That's all I needed and I pulled all the way out looking a my sisters gaping asshole and then shoved back in to the hilt. She started grunting to my thrust as I slapped my balls against her backside over and over. I could feel Zoe's fingers rubbing the underside of my erection as I plowed into her. I was not going to last much longer, when I heard Z start a low continuous moan, getting loader and louder. Her ass then tightened down on my cock and she screamed, "fill my ass with your cum. Do it now, fill me up."
That's all it took, I could feel her body convulsing and sounds of pleasure coming out of her mouth when I unleashed a fountain of cum into her ass. I pumped into her over and over, filling her as she cried out, "I'm cuming!" It was all I could do to hang on to her hips as they waves of pleasure washed over both of us.
Finally, our energy spent, we collapsed on the bed. I was laying on top of Z and could feel her breathing. I could feel the sweat on our bodies. Sadly, I rolled off my beautiful sister and my cock slipped out of her, i heard her moan. She quickly rose up, turned around and sucked my dick into her mouth, letting her tongue bathe my semihard cock. I twitched as she cleaned me. I looked up to Z;s ass and watched as a steady stream of my gooey, white cum oozed out of her ass. I watched as her rectum was closing one heart beat at a time. My cum ran down and across her pussy, then down her inner thigh.
When Z was done driving me crazy with her tongue bath, she crawled up and into my arms and said, "Thank you Master, that was amazing. Now I have had your seed in every entrance I have. I know now, you can fuck me anywhere, anytime it pleases you Master."
That was new. Master? I could get used to that. As we lay there in each others arms, I looked over at the Laptop and could see mom laying naked, face down on her bed, unmoving. Didn't see Aunt Corrie. Then my bedroom door opened and Z and I both looked as Aunt Corrie stuck her head in and said, "You guys are to loud." She then shut the door. A few seconds later, we could see her back in moms room. She crawled into bed with mom, pulled up the covers and shut off the lights. Zoe looked at me for some kind of answer and I just shrugged and said, "Don't worry, Aunt Corrie's cool. We'll worry about it tomorrow." I pulled up the blankets coving us and held Zoe until I fell asleep. My last thought was, Master?
