“Here, the angle’s wrong,” Darcy said. She lay down on the bed, next to me. She held her boobs in position, squeezing them forward.
I froze. To this point, this had all been stuff my sister was doing to me. I’d never even moved, actually, unless you counted the spasms of my shlong. Now she was lying on her back, waiting for me, and it felt weirdly like a big step. As if this was some new threshold we’d yet to cross.
My sister didn’t move, she just lay there. I got the feeling she’d stay all night unless I did something. So, I rolled over and spread my legs over Darcy’s torso. Then I slid my dick into the tunnel between her tits.
“See, much better,” Darcy said. She held her breasts tight around my hardness and, slowly, I began to hump her chest. Every time my cockhead popped out of her cleavage my sister gave it a little kiss.
This felt different. It shouldn’t have been, really. In fact, it was probably less invasive than the blowjobs I’d grown used to. But something about the way I rocked back and forth on my sister’s body, it felt like way more.
Maybe it was how the movement seemed awfully close to fucking. Or the fact that I was the one now actively getting myself off, using my sister’s body to do so.
“I want you to cum, Ethan,” Darcy whispered, “I need you to. Shoot your stuff all over my face. Mark me. Do it. Give your big sis what she’s begging for. Pleeease.”
Darcy’s body was incredible. Fucking her tits was amazing. But it was her words that put me over the top. As my soon as my sister started begging, my sperm rocketed out of my shaft. I did as she asked, spurting on her face. Long white drips hung off her nose. One eye shut where I’d accidentally splashed her.
Darcy giggled and licked herself clean, like a kitty. “I missed that this morning,” Darcy said. She gave me a tight hug. “Oh, I wish I could stay in bed with you, too, baby. But Mom and Dad would not appreciate finding us like this.”
My older sister stood up, wiping the last of my cum off herself.
“Thanks, Darcy,” I said, plaintively. It was awkward. But in the moment, I felt like I had to say it.
“Of course, sweetie,” Darcy said, “I’ll see you tomorrow. That’s when the fun can really start.”

I was already awake when Darcy came in my room the next morning. She looked at me with glee, like we were going to Disney World, not doing our now-daily ritual.
“Today’s going to be so awesome,” Darcy sang to herself. I couldn’t help but get caught up in her enthusiasm.
I stripped off my boxers and let my dick spring free, somehow as hard as I’d ever seen it. Darcy was wearing her usual uniform: t-shirt and panties (pink and blue, respectively) with her hair tied back. She knelt between my legs and slowly teased at my cock, dragging kisses up the shaft.
Darcy slithered her hand around my dick and popped the head in her mouth. She hummed, happily, vibrating in a very pleasing way. Then she began deliberately working me. Every time was different with Darcy, and I guess that’s what made it so amazing. I could never get used to one sensation before being introduced to a new one.
I realized how hurried my older sister had been with her oral performances up till then. I’d thought she was concentrating on my pleasure, but, in fact, she’d been getting me off quickly so she could get to work. Now Darcy took her time, she edged me slowly forward, inch by incredible inch, building me up to something that started to feel volcanic.
My sister sensed me building and she increased her speed. Made sexy little slurps and chokes. I was on the precipice now. I could feel it building. My sister could have breathed on me and I would have blown. But she wasn’t breathing. She was sucking, stroking, slurping, and suddenly…
Darcy stopped.
My sister dropped my dick and sat up straight. Her butt perched on my knees. I was already gasping for air.
“So,” Darcy said. She reached up to play with her hair, twisting it around her finger like a little girl. “I’ve been thinking. Since I’ve been doing this stuff for you – you know, getting you off – that you might, like, be willing to do the same for me?”
Honestly, my sister could have asked me to leap off the Ben Franklin Bridge at that moment and I’d have agreed without thinking about it. And, to be fair, Darcy asked for relief in a way that made it seem equally as dangerous. But I was honestly fine with it. She was right, I should be returning the favor. In fact, I felt bad that she even had to ask.
“Oh, I knew you’d understand,” Darcy said, “Here, why don’t you do me and then I’ll finish you off.”
My older sister fell next to me on the bed. She stripped off her panties and flung them across the room. Then she spread her legs. I noticed that the patch of hair that had been there the last time I saw her pussy was gone. Darcy had shaved her snatch completely.
“Use your fingers, OK?” Darcy said. She grabbed my hand and put it in the warm space between her legs.
My sister was already dripping, and her sex felt almost hot to my touch. I dragged my finger through her slit. Darcy arched her back and sighed.
“Oh God,” Darcy said, “You are really terrible at this.” She got up on her side and fixed me with a very serious look. “OK, little bro, don’t worry. I’ll show you.”
Very patiently, my sister took my hand and showed me what she wanted me to do. I got a guided tour of Darcy’s cunt, where to touch, how, and when. What to feel for, what to listen for, and what to avoid completely.
“There’s more stuff,” Darcy said, “But I think that’s enough for now.”
I put my hand back in my sister’s pussy. I teased at her slit, then scooped her moisture up and bathed her clit with it. I gradually rubbed her little nubbin back and forth, then slid a finger from my other hand inside her sex. This time, Darcy groaned with pleasure.
I started stroking my sister’s clit faster. I put my finger inside her pussy and felt it squeeze down. A lot like her mouth would do on my dick, actually.
“Oh, that’s much better,” Darcy said. She gave me a self-satisfied smile, then reached over and grabbed my cock. It hadn’t flagged for a moment in all that time, though my orgasm was now less impending. “We’ll get off together, OK?”
I nodded, staying focused on making my sister cum. I pumped her pussy with my fingers and ground her clit with my thumb. Darcy’s breath hitched. She grabbed my wrist and held my fingers in place. Her back arched and she made a low moan.
Darcy’s hand squeezed my dick so hard it almost hurt. With a remarkable quickness, she jerked me – one, two, three – and I reached my own orgasm. My spend shot out. I heard my sister continue to cum with me. Both of us lost in our own solitary pleasure, lying next to each other on the bed.
My cock softened. Darcy’s pussy tightened, expelling my sticky fingers. My sister took her sperm-y hand and licked it. I took her hint and tasted her own liquid from my fingers. It was tart, salty, strange, but also quite alluring. I’m tasting my sister’s pussy, I thought to myself, and it made me feel wrong and that, in turn, just turned me on again. God, I was so broken.
