Sexiplicity Ch. 07

"Do you think your mom has lube in her nightstand with her toys?" he asked me.

"Maybe... I've never looked," I said.

"I know that... well we need some... in case she doesn't. It's been awhile since your dad died so she'll need to remember how again... so preparation is important too. Unless she's been using toys in her ass... we don't know... do we?"

"No we don't... I really don't think this is necessary... what's wrong with normal sex with her?" I asked.

"Nothing... it's great... but I can tell she's already gotten used to us... she wouldn't have mentioned how tight Becca was and let slip about she and your dad finding ways around how loose she is... I'm doing this for her, Peter," he said.

"Oh, right... doing it for her, huh... you expect me to believe that? You haven't done a selfless thing since you popped into my head!"

"First time for everything," he said, closing the laptop.

He got up off the bed and went over to Becca, still working on her homework. He kissed her on the cheek and said, "I'm going to the corner store real quick, want anything?"

"No, I'm still full from lunch," she responded.

"Okay, see you in a bit," he said.

I don't think he was going to give me back control until he got what he wanted. I wasn't falling for the lie about 'doing this for my mom' he wanted to try anal and that was obvious. Although he did have valid points to what he said. Mom did seem jealous of how tight Becca surely was and did let slip about solving the problem with my dad. I had to admit I was a bit curious what she would do when evil Peter got to that point.

He took us out the front door, down the street to the corner store and in the isle with the condoms. I never noticed before all the different lubes until now. He recalled what we read online. The thicker lubes don't dry out as quick and are best for anal. He found the one we wanted and plucked it from the shelf. Along with the lube he grabbed a Twix and some gum before heading to the counter. He set the stuff on the counter and looked up at the girl behind it for the first time. To my shock and to his glee we both knew her. Brittany, the skinny, tiny girl from school was staring back at us. She looked nervous since Becca had told her to stay away from us, but that didn't stop evil Peter.

"Hey, Brittany... didn't know you worked here," he said.

"Yeah, just on the weekends," she said shyly before reaching for the three items.

She hesitated when she reached for the lube, giving evil Peter more ammo.

"Yeah, you know why I need that right... you got a look in the aquarium's restroom remember," he said.

Her pretty face went bright red. She looked around the store to see if anyone had heard him. Evil Peter looked around the store and discovered that we were the only ones inside besides Brittany.

"We're alone, want another look?" he asked.

"Umm... no... I shouldn't... Becca said to stay away from you."

I started complaining in my head to just buy the stuff and get home and to not flirt with Brittany but of course he didn't listen.

"What she doesn't know won't hurt her," he said.

"Then how did she find out the first time," Brittany asked.

"Wasn't me... I didn't say a thing... maybe she saw you coming out of the men's room."

"No, I don't think so... she found out somehow... she'll find out again," she said grabbing the lube finally and ringing up the items.

Her hands were shaking, she was nervous. She said the total back to us, but evil Peter didn't retrieve any money yet. Instead, he leaned forward toward her.

"This place have a back room? You could finish what you started?" he said.

Screaming did no good, but I still yelled. Was he seriously wanting to cheat on Becca! Did this evil personality have no morals at all!

Brittany trembled, her face stayed red and she flushed from his invitation. Was she actually considering it?

"I shouldn't, I can't... I have to watch the store and what about Becca?" she finally said with new fortitude.

"You saw it, there's plenty to go around for both of you?" he said

She swallowed hard, but then read the total back to him with a look in her eyes that she was serious and not about to do anything with us. Evil Peter gave up, paid her and with our things in a small sack, headed back home.

**

Before going inside, we heard Tiffany talking to someone in the backyard behind the fence. Evil Peter got closer and we realized she was just muttering to herself in incomplete sentences, kind of like a pep talk.

"You can do this... try and forget... find one like it...," she was mumbling.

Evil Peter pulled the string extending through the fence and opened the gate to the backyard. Tiffany shut up quick when she saw us.

"Hey, sis... who ya talking to?" he asked her.

"No one... nobody," she stammered.

"You okay?" he asked her, feigning real concern and walking up to her.

She looked up, trying to keep her eyes on our face and nowhere else, "No, Peter... I'm not alright."

"And it's all because of me, right?" he asked.

"Yes... you and your... damn you!" she said.

"You know what, Tiff... screw it... let's just not try and fight it. What Mom doesn't know won't hurt her... we'll just do it behind her back. It's obvious you want to... I want to... Remember how good it was... she'll never find out," he said, putting his hand on her shoulder.

She was struggling, I could see the fight in her eyes, on her face. The urges were killing her and the memories.

"What if she finds out? What if she catches us?" she asked.

This was not what I expected... I expected an all-out NO! I hate you, go away! But this gave evil Peter what he wanted... a way in again.

"We'll just have to be careful... find time when she's at work or shopping or sleeping," he said.

"We really shouldn't, Peter... I mean not only will it be behind Mom's back but we're siblings... it's not supposed to be like this... but..."

"But you can't stop thinking about it," he said, cutting her off. "Me either... that's why we should just stop fighting it and just enjoy one another."

She frowned, and said, "I was going to say, but what about Becca too?"

"You know I can handle both of you... already proved that," he said.

"Yeah, with me and Mom and Becca... you're something, aren't you little brother," she said, hitting our chest.

"I'm something alright... so what do you say? Want to pick up where we left off?" he asked.

"Fuck! I'm so torn... its killing me!" she said, turning her back to us.

He moved to stand right behind her grasping her hand in ours and placing it on our cock. She didn't pull away, and I knew he had her again. First Mom and now Tiffany. What we both thought was gone forever, he had back in record time.

Her hand caressed our cock through our pants, she turned around, still holding our growing bulge and said, "I don't know how we're going to pull this off but I can't keep fighting it. Sneak into my room tonight," she said, pulling her hand from our dick.

She turned and walked away to the backdoor of our house, looking back before she entered.

"That was too easy," evil Peter said out loud in my body.

"I have to admit, assface... I'm impressed... I thought she'd be more stubborn," I said.

"Yeah, well... you still underestimate our cock, fuckface," he said back.

He took us back out the gate, closed it and went in the front door. Mom was cooking dinner... smelled like tacos. Evil Peter hid the lube under one of the couch cushions and then headed upstairs to the attic to see how Becca was doing on her homework. Something I needed to actually do, but since he had control was impossible.

"Hey, babe... I'm back," he said as we entered the room.

Becca was just closing her books. She stood up and came over to us, grabbing the small sack from our hands.

"Whatcha get?" she asked, looking in. Gum and a Twix? I thought you hated Twix's?"

"Oh... yeah, I do... it's for you," he said.

"Oh... thanks... but I said I didn't want anything," she said, giving us a kiss.

"You can save it for later."

She tossed it on the bed and kissed us again, a bunch of time, until our cock started to grow. But then she stopped and walked past us to the door.

"Smells like dinner's almost ready. I'm going to see if your mom needs my help," she said, leaving us with half an erection that didn't stop immediately.

Evil Peter walked toward my full length mirror on the back of my closet door and pulled down our pants and underwear to get a view of our growing cock.

He watched it, forcing me to watch it, bounce and pulse to full height with no further stimulation in the mirror.

"It's magnificent... I can't believe you ever hated it," he said as our cock throbbed and pulsed. He was speaking out loud, when suddenly from behind us came Tiffany's voice.

"Now who's the one talking to themselves?" she said, walking into my room and closing the door.

Evil Peter just turned toward her, full hardon and all, not trying to cover up or anything.

"Oh, hey, sis... just giving it some air?" he said.

"I see that... but what's this about hating it?" she asked, walking toward us.

"Well, before the accident... I always thought it just got in the way and made things difficult," he said.

"And now," she asked, reaching out and grabbing the middle.

"And now... all that's changed... it's become pretty awesome," he said.

"I'd say... you definitely have changed since the accident," she said, moving her hand up and down the rigid shaft.

It felt so good... Tiffany was touching my bare cock again... something I never thought would happen again. She bit her lip as she caressed it up and down. I could see on her face what she wanted, but instead she pulled her hand away and turned toward the door.

"I just came up to tell you dinner's ready, put that thing away until later... I can't wait," she said, turning to leave my room.

Evil Peter turned us back to the mirror, admiring our cock again as a droplet of pre-cum began to emerge.

"You don't hate it now, do you, pussy... you're slowly learning what it can do and the power it has... I dare say you're beginning to love it," he said, yanking up our clothing to cover the massive member.

He wasn't wrong.

Dinner was interesting. Both Mom and Tiffany were trying to act unhappy still. Or at least not give away the fact that they were both either doing me or going to do me. Tiffany was really trying to act miserable and barely said two words to me during dinner. Mom just shrugged her shoulders at me, thinking it was going to take time for her to come around to having sex with me again as we discussed. Little did she know, it was already in the works.

Becca tried to carry the conversation and did a pretty good job. Evil Peter, still in control, behaved himself and pretty much acted like I would have. When dinner was over, Becca helped Mom clean up. Tiffany left the kitchen to the living room, catching my eye and wanting me to follow. He did.

"What time are you planning on coming to my room?" she asked.

Evil Peter started laughing in my head, saying, "Damn, your sister wants it bad."

"I don't know... when everyone's asleep, I guess," he answered her.

"That could be late, since its Sunday tomorrow," she said, looking put out.

"Sorry... what do you want to do?" he asked.

"What can we do? Becca's in our house and Mom's probably not going to get called into work again on a Saturday," she said, shaking her head.

"I guess we have no choice but wait," I said.

"It's killing me... you don't know how bad it's been for me... you've had Becca... you get to have sex with her, but I've had nothing!" she said as quiet as she could.

The water was running in the kitchen so I doubted Mom or Becca could hear us.

"I'm really sorry, Tiff... I can't imagine what it's been like for you... I promise I'll try and make it up to you tonight," he said.

"And tomorrow and the next day and the next... I need to catch up, if we're really going to start this again," she said.

"Okay, wow... you're really bad off," he said.

"Honestly, Peter, it's been the worst days of my life... to want something so bad and not have it and have to hide the fact of wanting it... pretending to hate you when all I wanted to do was jump you and have you inside me again. Right now I'm so horny and wet, you could ram it home with no friction at all!"

"Okay, okay... good hell, Tiffany... don't fall apart on me... I'll come to your room just as soon as I can tonight."

"You better!" she said, and turned to leave.

Evil Peter started laughing in our head as she walked away. "You're sister is a fucking slut about our cock. She basically wanted to rape us in the hall," he said.

"Yeah, I heard her... wow she has been dying for it since she found out about Mom and us. She's going to literally attack tonight when we go and see her."

"I'll be ready... we'll fuck her just as hard as she wants," he said, chuckling in our head.

Evil Peter still had control when evening was wrapping up and everyone was getting ready for bed. Tiffany made sure to make eye contact with us when she headed to her room. As did Mom. The only one that ironically didn't expect sex that night was my girlfriend. She just kissed me goodnight, and went up to her bed.

Evil Peter didn't see any problems with the situation, but I did. All he cared about was fucking and didn't worry about logistics, like who first and how not to get caught. I mean, shit, both my mother and my sister were expecting me tonight and when I don't show up to one because I'm with the other, the one not getting any may come looking. It would be easy since I'm supposed to be on the couch. When they don't find me there, I'm bound to be busted with the other. I tried to explain this all to evil Peter but he was so caught up in fucking Tiffany and even worse, fucking my mother in her ass for the first time, that nothing I said made any difference.

"You worry too much! We'll be fine. I'll take Tiffany first. Pound her for an hour or so and then take a little break before your mom," he said.

I figured it was the best option. Mom would be the best choice to do second since she was the least likely to come out of her room to find me. Tiffany was all sorts of worked up and wouldn't wait in her room more than a half hour after everyone went to bed.

Evil Peter waited until all the doors were shut and the noises in the house of people getting into bed was silent; about fifteen minutes. Sliding out from under the sheets on the couch, he snuck as silently as he could down the hall past Mom's room and cracked the door on Tiffany's room and let himself in. I had to admit I was excited, our heart was racing as we noiselessly closed the door behind us and took a step into Tiffany's dark room. He headed toward her bed, a dark outline in the room ahead of us, when suddenly the nightstand lamp came on, blinding us.

"Took you long enough," Tiffany's voice sounded from the blindness.

"Just had to make sure everyone was settled," he said back as we tried to adjust to the light.

When we could finally see, what we saw was incredible. Tiffany was lying on her bed, completely naked with no covers on her body. Her sex was open and glistening as were her fingers on her right hand. Our eyes widened as we took in her toned, sexy body, rock hard nipples on her round firm breasts. Our already semi-hard cock lurched in our pajama bottoms as our lips parted in a sigh.

"I started without you," she said. "Now get over her and fuck me."

She was whispering everything but it was a forceful commanding whisper. Evil Peter walked around her bed to the side as he kicked off our pajamas until he stood naked next to the bed with our long cock throbbing and pulsing toward Tiffany.

"Gawd, that thing is so fucking big!" she said rolling over and grabbing our hard dick.

Sweet bliss followed as she took our head in her mouth and continued down a few inches, only to retreat and suck the head before taking more the next descent. She continued sucking and bobbing with her mouth only as she laid on her side and evil Peter stood next to the bed. Our cock got even harder as my sister worked it over with her talented mouth. She started playing with her clit and wet pussy as she sucked and her nipples remained hard as evil Peter alternated from viewing her sucking us and playing with herself.

I just basked in the pleasure and watched her red head move up and down my long cock. I had no control, but I at least got to enjoy the pleasure. She wasn't as talented as Mom, never got close to taking all of my cock in her mouth, but she was more experienced than Becca and had me and evil Peter, humming with pleasure, as our cock plumped and our balls tightened. She sucked for about five minutes before letting us out of her mouth and saying, "I need you in me now!" in that harsh whisper.

Evil Peter grabbed her ankles and spun her around so her ass was partially off the bed. She lifted her legs and he spread them wide. Letting go on her left leg, he pushed our cock down and without messing around, just rammed it into my sister's hot, wet pussy, all the way to our balls. She was right about no friction. Even our long wide cock slid into her with no hint of resistance. It felt incredible. Tiffany's head fell back and she let out a squelched scream of pleasure as every inch rushed into her. Evil Peter grabbed her loose ankle and with both in our hands, pushed her away, lifting her ass upward as he began driving our cock fast and hard into her body. Each thrust was deep and powerful, making even her small, firm breasts roll toward her face with each lunge.

She moaned and whimpered as he pounded her just like he said he was going to. Our cock was soon covered in her juices, glistening in the lamp light as it appeared and disappeared rapidly in and out of her. It didn't take long before he had her cumming. She was so worked up and starved for it, that in less than five minutes of banging her, she was already shaking and flooding with orgasmic bliss. He didn't let up either, just fucking her hard and fast all through her long orgasm, a very pent up one to be sure.

She finally just fell limp, just her chest was moving rapidly up and down. The rest of her was dead weight like she was melting into the bed. Evil Peter, finally slowed down his thrusts, as Tiffany struggled for air with her eyes closed, nipples hard and body limp. He eased our cock in and out, never fully stopping until she finally opened her eyes and looked up at us.

"Oh my, gawd, Peter... the things your cock does to me... it was everything I thought it would be. I never want to stop again, ever," she said.

"We won't have to," he said, sliding in deep and back out.

"You didn't cum with me?" she said, finally noticing he was still hard and fucking her.

"Not yet, you came fast," he said.

"I was so horny and pent up... you have no idea," she said.

"I think I do," he chuckled.

She just smiled up at us, looking as hot as fuck from her orgasm flushing her body with life. He started to speed up his thrusts again and her smile got bigger.

"Think you can make me cum again before you do?" she asked.

"I can sure try," he returned.

"Okay, brother... let's see you try, but first, I need to change positions."

He pulled out and she rolled over and got on her hands and knees, looking back at us over her shoulder. She pressed her ass toward us and evil Peter bent our cock back down, easing it into her doggy style all the way until our hips hit her butt. The friction was less in this position, but she still felt amazing.

"Fuck, you go so deep!" she said, looking back again.

Our wide cock spread her open, and when evil Peter looked down, he immediately noticed her little rosebud asshole. It was covered in her orgasmic juices that had run from her contracting pussy and forced out by our cock. Anal sex instantly came to his mind again and I panicked a little, thinking he was going to try it with Tiffany.
