Not with My Twin!

Nursing hangovers from hell, the four of us were slow to wake the next morning. Without coffee, we were a grumpy bunch. The original plan had been to spend the day at the shack and head back around nightfall. That plan fell apart quickly. We packed up our stuff and drove into town for a late breakfast. Robin and I had to return Uncle Joe's keys and shotgun, so we said our good-byes in the parking lot of the restaurant. Not a word was mentioned about what had happened after Amber passed out.

Robin and I visited with our uncle for as short of a time as possible before getting into the car for the ride home. It was early afternoon and we were both feeling better. Once I hit the highway for the hour ride home. After riding in silence for several miles I asked Robin, "Should we talk about what happened last night?"

"No," she said, head buried in her cell phone.

Her unwillingness to talk about it couldn't stop me from thinking about Amber's dark nipples or the wild, passionate look in Mallory's eyes while she desperately rubbed her pussy or, well, what Robin and I had done. I got hard, really hard.

I glanced at my sister staring at her phone and tried discreetly adjusting my cock. She was wearing a tight t-shirt that outlined the shape of her tits. I hadn't noticed it earlier, but she wasn't wearing a bra. The car hit a slight dip in the road and I watched her breasts sway. Eyes back on the road, I rubbed the front of my pants.

"Really?" Robin asked, catching me rubbing my cock.

"Sorry, I can't help it," I apologized. "Sometimes it has a mind of its own." I glanced at her out of the corner of my eye. She was staring at my lap. I caught her licking her lips. Did that mean anything? "Can I ask a question about your friends?"

"If you're going to ask if we ever mess around, the answer is no," she said. "Amber was lying about me being a good kisser. She doesn't really know. They told me to play along just to make you hard." I'll admit I was disappointed, but that wasn't the question I had in mind.

"Can I fuck them?" I asked, blurting out my real question. Back in high school, Robin and I had made a pact that we would never date our twin's friends. Her answer surprised me.

"Only if you do it in front me," she giggled.

"Is that something you want to see?"

"They have boyfriends," she said, dismissing the idea. She asked who I liked best and I admitted I was more attracted to Mallory than Amber. "That was really hot what she did last night," Robin said.

"It was fun teasing her," I said, hoping that might start a conversation about what we had done last night. Robin didn't reply. I waited a few moments before I said, "We went too far last night, didn't we?"

"Probably," she agreed. We were lost in our thoughts for a few moments before she said. "It was hot though."

"You're a good cocksucker," I offered. That earned me a slug in the shoulder and a big grin from her.

"Why did you make me do that?" she asked. I noticed she kept checking my lap to see if I was still hard. I was.

"I don't remember making you do that."

"You turned down anything from me," she said.

"Yeah, but how much would you have been willing to do?"

"Guess we'll never know," she said. "Except now you owe me." I nodded. I did. "Maybe I'll just ask for lots of rides to work or something."

"Well, that's lame."

"Why? It doesn't have to be something sexual, does it?"

"Doesn't it?" I asked, assuming that's what anything meant.

"What if I said I wanted to see it, right now. Would you show it to me?" she asked. I said I would. "You're not doing anything," she pointed out.

"Is that what you want?" I asked. I glanced at her, saw her still gazing at my crotch and couldn't tell if she was waiting or what. I fingered open the button at the top of my shorts and shot her another glance before carefully working the zipper and pulling out my long, hard cock. I stroked it a couple of times before putting both hands back on the steering wheel.

"Do you like showing that off to me?" she asked. I shrugged. I didn't mind. "But I'm your sister," she added.

"You're still a girl," I pointed out.

"But I'm your sister," she repeated, emphasizing the last word. I guess she was trying to make it feel wrong.

"Last night, you did more than just look at it," I reminded her. I stroked my cock a couple more times, showing off its length and letting her see how excited I was.

"I think you should stay like that," she said with a whimsical smile.

"Are you going to do anything?"

"Not while you're driving."

"What about when we get home?"

"Maybe I just like looking," she said and that's all she did, but she did it a lot. She spent significantly more time staring at my hard cock than she did texting on her phone.

"Enjoying yourself?" I asked, annoyed with the anticipation of something more but the closer we got to home, the lower my hopes became.

"I am," she said, tapping away at her phone. "Mallory's asking about you. She's worried you might be pushing yourself on me."

"Does it look that way?"

"I told her you're being a good boy," Robin said. "And that I'm being a very bad girl." Looking at her phone, she giggled. "She wants to know how bad I'm being. What should I tell her?"

"That you're making me drive naked?"

Robin shook her head. "I told her I was refusing to talk about last night with you. She doesn't need to know what we do, does she?"

"We're not really doing anything," I said, though I agreed with Robin. No one needed to know what we were doing, including Mallory.

I pulled up to our house and tucked myself back together again. I held my backpack in front of me as we walked into a house that turned out to be empty. There was a note on the refrigerator from Mom. Grandma fell. Heading to Indy. CALL ME AS SOON AS YOU GET HOME!

"She does know we have cell phones, right?" I said, passing the note to Robin.

"Except, this way she knows we're home," Robin pointed out, seeing through Mom. Robin called Mom from the house phone, proving we were really home. While they talked, I carried my backpack upstairs, tossed it on the floor and sat on the end of my bed.

I was still hard and wasn't sure what to do about it. I absentmindedly rubbed my hard-on as I considered what I should next. A shower sounded like the best idea. I left my door open as I got undressed and went into the bathroom that connected my room with Robin's. The door to her room was shut. Growing up, our doors were always closed and we had waged huge wars over the shower. I turned on the water and soaked. I jumped when I heard Robin's voice on the other side of the curtain.

"Mom said grandma seems fine. She with her at the hospital and she'll call back when she knows more," she called.

"Thanks," I called back, finding it very strange knowing she was in the bathroom with me.

"You're not jerking off, are you?"

"No," I said, laughing. "Did you want to check?"

She ignored my invitation. "Don't be a dick and use all the hot water, okay? I want a shower, too."

After my shower, I noticed the door to her room was still open. That felt foreign. I peeked inside her room. She wasn't there. Drying off, I dressed and headed downstairs. Robin sat in front of the TV, ignoring it while she worked her cell phone. She flashed me a smile before heading upstairs for her shower.

I watched her skipping up the stairs and wondered if anything else was going to happen. Absentmindedly channel surfing, I wondered what I wanted to have happen. Did I really want to make love to my sister? My cock stirred, giving its answer and annoying me. I tried ignoring it as I mused about how last night might have changed our lives. That open door felt different. Her talking to me while I was in the shower, that had felt really different.

Maybe that's all that was going to happen? Maybe we were just going to move past our modesty around each other? But that didn't explain the ride home, did it? She had known I was hard and wanted to see it. Did that mean she wanted to do more than look at it?

I was still wrestling with my mixed thoughts and emotions when I heard her skipping downstairs. I glanced at her as she walked past behind the couch towards the kitchen. She was wearing a tight t-shirt and no bra. That wasn't a change. That's how she usually dressed whenever we were hanging out. It wasn't until she moved passed the couch that I noticed the difference. Instead of shorts, she was only wearing panties. A moment later, she came out of the kitchen with a cup of yogurt and sat on the couch. "What?" she asked as I looked at her.

"Are you trying to get me hard again?" I asked.

"What? I always dress like this," she said, smirking as she spooned yogurt into her mouth. "At least, this is how I dress at college." She wasn't modest about how she sat, either. She was scrunched into the corner of the couch, mostly facing me. She left one leg on the floor while her other knee was bent and resting against the back of the couch. Her panties hugged her crotch and I couldn't stop noticing how they outlined her bare pussy lips.

Her mention of college reminded me of a question I had. "Did your roommate and her boyfriend really catch you masturbating?"

"Mm-hm," she said around her spoon. "Just like I said."

"What did you do?"

"I freaked out," she said, rolling her eyes as if that should have been obvious. "I fell on the floor, pulled a blanket over me and ran into the bathroom." She stared at her yogurt for a moment and I saw she was blushing. "It was sort of hot, though," she mumbled.

"You did not just say that!" I howled, laughing. "So, why didn't anything else happen with them."

"Awkward," she groaned. "She was my roommate, you know?"

I nodded as if I understood why that made it awkward. I didn't, but another thought occurred to me about last night. Doing stuff in front of Mallory had made a difference to Robin. Did that mean nothing else would happen if we didn't have an audience? Not liking that thought, I pushed it away in favor of a different question. "So who did you have the threesome with?"

"A friend," she said. "It just sort of happened. He was a fuck-buddy, you know?"

"Who was she?" I asked, remember the dynamic.

"A friend of his," she shrugged. "It only happened that one time."

"Did you like it?"

"I think I like being watched," she admitted before picking up that I was talking about something else. "OH!" she giggled. "Yeah, I guess I did. I mean, I'm really oral, are you?"

"You didn't notice?" I asked, making a direct reference to what we had done last night. A sly smile crossed her face as she squirmed a bit. "Problem?"

"Maybe," she smirked as her eyes moved across my body. "Girls get horny, too, you know."

"Yeah, but it doesn't show like it does for guys," I said, parting my legs so she could see my hard-on.

"It's sort of funny to look at you and think, 'that's how I would look if I were a man.' Is that wrong?"

"Wrong to think that or wrong to look?" I asked.

"Wrong to want to touch," she said.

"I don't know, maybe it's more like we're masturbating," I suggested, rounding out the thought as it occurred to me. "I mean, you're me and I'm you, right? So what difference does it make if we do stuff?"

Robin laughed at my logic. "So, if I was a guy, you'd jerk me off?"

"Probably not," I laughed, seeing the gaping hole in my logic. Still, something felt right about what I had said, too. I stood and moved to the couch. "Except you're not a guy."

"What are you doing?" she asked, watching me with wary eyes.

"Does it matter?" I asked, pulling off my t-shirt. "Maybe I'm just getting comfortable." I scooted a little closer to her before pulling off my shorts, too. Again, I had gone commando. "Is this okay?"

"Are you going to jerk-off?"

"I don't know, am I?" I asked, leaning back and watching my hard cock tapping against my stomach as it throbbed before staring at her watching, too.

"What happens if I get naked, too?" she asked.

"I don't know," I admitted. I hadn't thought that far. "Anything, I guess."

"You said that last night, too," she said, still staring at me. She moved closer and touched me. She ran her hand up and down my shaft. I caressed the back of her head. I wasn't urging her to do anything, I just wanted to touch her and didn't want to cross any lines. "I'm not going to blow you," she told me, looking into my face as her hand pulled on my cock. "I mean, not this time."

"Okay," I said, unable to feel disappointed. What she was doing felt both wrong and right enough. She pressed her lips against mine, we kissed, and I'll admit, that felt really weird.

"Too weird?" she asked, reading my mind.

"Different," I said, finding it interesting how I could be naked in front of my sister and still find it weird to be kissed by her.

"Use your tongue this time," she said as she pressed her lips against mine again. It took a moment before I could do it, but I did. I don't know. Maybe I was afraid she would stop touching my cock or something, but I opened my mouth and pressed my tongue between her lips. Our tongues touched, tentatively at first and then with more confidence. Robin pulled on my hard cock and our kiss continued until I put a hand behind her head and held her face against mine.

"This is so wrong," she gasped, pulling away far enough to say the words before pressing her lips against mine again.

"We should stop," I said, between kisses. My other hand had found her chest and I was groping her chest.

"I want this," she said, squeezing my cock.

"Okay," I said, unsure how she meant that and too excited to care.

Robin pulled away from me. She pulled off her t-shirt and I stared at her chest. Her nipples were hard and I pushed my face against them. I sucked on her closest tit before moving to her farthest one and back. She leaned into me and it took me a second realize she was pulling off her panties. It wasn't until I ran my hand down her back and cupped her ass that I realized she was naked, too.

"Look at me," she said, pushing my head away from her tits. I did and I gazed into eyes the exact same color as mine. I saw a tiny smile that looked precisely the way mine did. I saw her matching nose, cheekbones and chin.

She ran her fingers across my face and I could guess she was experiencing the same thing as me, recognizing how much alike we looked, how we really were twins with more similarities than differences. She swung her leg over mine, straddling me. My eyes went wide.

"Relax. We're only masturbating," she said as she directed my hard cock inside her hot, wet pussy and slide all the way down.

I gasped, in part because of how amazing she felt, but more so because of what she was doing. She gave my shaft one long, slow stroke, as if making sure I knew what she had done. "Does this count as anything?" I asked.

"I think it counts as everything," she said, pressing her lips against mine as she slowly stroked up and down me again. My hands found her tits as we melted together into a single being. Any squeamishness about kissing my sister had vanished the first time our tongues met. We fell into synch with each other. When I would moan, she would do the same. When I squirmed, she squirmed. When I pressed up for a deeper thrust, she was pressing down for the same. We clutched at each other in desperate need for what we were doing.

"So good," I gasped.

"I know," she moaned.

"I'm so close."

"Me too. Cum with me."

Robin's pussy contracted around my hard cock. Her pussy fit my cock perfectly, a velvet lined glove to the digit of my hard cock. She felt hot and perfect as she squirmed against me and I knew she was clinging to the edge of her orgasm, the same as me.

I couldn't last. I didn't want to and didn't even try. Crushing my lips against hers, we moaned together as our orgasms arrived. My cock exploded inside my sister, throbbing and straining against the squeezing and contractions of her orgasm. It felt as if her pussy was milking me dry and my cock gleefully filled her and our mouths stayed together until the last shiver had delighted us.

"Fuck," she sighed, resting on my thighs with my cock still inside of her. "Did we really just do that?" She looked between us as if she needed the verification of seeing my cock inside her pussy.

I brushed a strand of her brown hair out of her face. My hand slipped down her cheek, over her shoulder and landed on her bare breast. She felt as sweaty as I did. I smiled at her, she smiled back and our smiled turned into giggles.

"You're a fucking pervert," she said.

"Me?" I said, trying to sound shocked even though I was still laughing.

"I'm serious, I can't believe you just masturbated right in front of me," she said, working whatever muscles girls have down there and squeezing my cock before she swung off of me. She held her pussy as my load dripped out of her. I looked down at my spent cock, shiny and wet looking with its coating of her and me.

"Look what you did to me," I protested as she ran giggling towards the downstairs bathroom to clean up.

When Robin came back to the living room, she flopped down on the couch and stayed naked. "So how weird was that for you?" she asked.

"Pretty weird," I admitted.

"Do you want to get dressed?"

"No," I said, admiring her naked body.

"Me neither," she grinned. She went back to texting on her cell phone as if nothing had changed, except whenever one of us moved. Like when I went into the kitchen for a snack, Robin's eyes tracked me, watching my cock. I did the same thing whenever she left the room, too, admiring her ass when she was leaving and appreciating her front when she was returning. Like when she got up, picked up her clothes and headed upstairs. I wasn't sure what that meant until I saw she was still naked as she came back downstairs.

About an hour slipped away with nothing happened. It was growing late and I was finding it difficult to keep my eyes off my naked sister. My cock grew hard again and I rubbed it a few times.

"Problem?" she asked, sounding exactly how an exasperated sister usually sounds whenever her brother does something that could be construed as annoying. But the tiny smirk at the corner of her mouth gave her away as much as her eyes did. She had already noticed that I grown hard. Her checking me out was part of the reason why it happened.

"Blow me," I said in a typically brotherly fashion.

"Eat me," she shot back, parting her legs as if it was an invitation.

"Right after you blow me," I said, waving my hard cock at her.

"Bring it over here," she said in that snotty way sisters have of talking to their brothers. She stayed in her corner of the couch though her eyes were still on my hard prick.

"Fine." I walked over to her and shoved my hard cock in her face. Robin opened her mouth and began sucking it. I played with her tits as she sucked me and things were feeling really good when the phone rang. I don't know why, but we exchanged a look of panic, as if we had just been caught doing something we both knew we weren't supposed to be doing.

Robin laughed and picked up the phone sitting next her. "Hello?" she asked, giving my dick another lick before straightening up and pulling away. "Oh, hi Mom," she said, her eyes wide. "How's grandma?"

Being a brother, I poked my prick in Robin's face a couple times as she tried to talk to Mom. Annoyed, she swatted me away. That's when I dropped to my knees in front of her, pushed her legs apart and pressed my mouth against her pussy.

"Stop it!" Robin sharply said. I flashed her a bird and kept licking. "Nothing, Mom. Robbie's being a dick, that's all." She listened a while longer, trying to squirm away from me, but I wouldn't let her. Finally, when she firmly pushed my head away from her pussy, I stopped trying to lick her. Instead, I sat next to her and groped her as she talked to Mom.
