The store wasn’t the typical mall brand you’re probably thinking of, though it might as well have been for all they’d cribbed from their more common competitor. Darcy went through like she’d planned it all beforehand, pulling down panties, bras, and other assorted items, and marched to the changing rooms in the back.
“Wait here,” she told me. I was very relieved when she said it. Our earlier close call at the movie theater had been enough excitement for me. I found a small stool nearby and sat down. The store wasn’t busy, but it wasn’t well staffed, either. There was an employee over by the registers, but that seemed to be it.
As soon as I got comfortable, Darcy skipped out of the back area. She was wearing a dark green silky slip with a plunging neckline. She modeled it for me, doing a little spin. The outfit wasn’t so revealing, but it still felt strange to see my sister in it, showing off in public.
“Well?” she asked, hands on her hips. Apparently, I’d spaced out a little. I wasn’t sure what to say, to be honest. Did she look hot in it? Absolutely. Was I, her brother, supposed to find her hot? That I was less sure about. Who was she trying these on for, anyway? For a future boyfriend? It couldn’t possibly be for me.
“You look nice,” I said. Darcy made a frustrated grunt and stormed back to the changing rooms.
She came back out in a matching pink cami and shorts set. Again, my sister twirled for me. She looked good. Was I supposed to tell her she looked good? Mostly I wanted to get this over with. Being caught in the lingerie store with an erection over my sister seemed like a bad idea
“Very sexy,” I said. Darcy shook her head at me and went back. She took a much longer time. I kept glancing over at the registers, but no one noticed us. Maybe we would be OK. What was wrong with trying on stuff, right? And Darcy and I didn’t look so similar. I could be her younger boyfriend. I’m sure this happened all the time. But I kept looking over, nervously.
Just as I was about to finally relax and pull out my phone, Darcy sauntered out. She was wearing a fire engine red teddy this time, pushing up her already prominent breasts and cut so tight at the crotch I could see her pussy pressing through.
“Wow,” I said. I hadn’t even intended to speak. It dropped out of me. Darcy turned to show me her backside and I said it again. “Wow.”
My sister didn’t say anything, but she smiled big and blushed almost as scarlet as the outfit she was wearing. She ran back to the changing rooms. The outfits were getting smaller and smaller. Was she really going to come out wearing less?
Instead Darcy popped out less than a minute later, wearing the exact same outfit as before.
“No cameras,” she hissed happily, then took my hand and led me back. This seemed like a tremendously bad idea, but my sister wouldn’t let me argue. Instead we went into one of the changing rooms. I saw Darcy’s clothes piled in the corner.
My sister pushed me back against the wall. She dropped to her knees, taking my pants and underwear with her. Before I could protest, my penis was in her mouth.
This was more like the standard Darcy blowjob. Fast and hungry. She slurped up and down my dick like she’d been poisoned and my cum was the only antidote. It didn’t take much for me to be close.
I heard a set of footsteps heading our way.
“Oh God,” I said.
“You close, baby?” Darcy asked.
My whole body froze. My older sister kept sucking. The footsteps got softer as they went in the other direction. Either we were totally safe, or someone was heading off to call the cops. There was no in between.
I was so worried, my cock actually started to soften, but my older sister wouldn’t take no for an answer. She redoubled her efforts, rolling my balls in her fingers and pumping me with her fist. That got me back up right quick. A moment later and Darcy was making her trademark swallowing sounds as she digested my seed, spurt by spurt.
Gulp. Gulp. Gulp.
She looked up at me with a supplicant smile, then stood.
“Better?” Darcy asked, as if I was the one who’d demanded she do this in the first place. I couldn’t speak, so I nodded. “Good. Go back so I can get changed.”
A few minutes later, Darcy came out wearing her yoga pants and tank top. She was holding the red teddy in her hands, but everything else had been left behind. She was about to head up to the register, when I noticed a streak of my cum was still on her chin.
“Oops!” Darcy said, “Thanks, E. That would have been embarrassing.” She quickly wiped her face with her hand, then brought the teddy up to pay.
“Did you find everything you needed?” the cashier asked. She was blonde, petite, and very pretty. Her nametag said, I kid you not, Victoria. I couldn’t meet her eyes. Suddenly, the fake wood floors were the most interesting thing in the world.
“And then some,” Darcy said.
“Your, um, friend got what he needed, too?” Victoria asked, eyeing me. She said the word ‘friend’ in a hopeful way. Like she didn’t want Darcy to correct her.
My sister elbowed me in the ribs so I would respond.
“Um, yeah. I mean, yes,” I said, “Thank you.”
“Next time let me know. I’m always here to help. You know, special requests,” Victoria said. She looked right at me when she said it. Then she and Darcy shared a wicked grin.
Again, Darcy made me pay for the clothing. “To thank me for all the nice things I do for you,” she explained. I didn’t even bother to argue.
When we left the store, Darcy reached into the bag and showed me the back of the receipt. Victoria had written her phone number there with the words, ‘Call me.’

We walked around the mall a little more, but when I found the video game store, Darcy announced it was time to go home. We went out to the parking lot and found her red Jetta.
“I’m really tired,” Darcy said, giving me a big yawn while she tossed our bags in the trunk. “Drive us home, kay?”
She handed me the keys. They felt oddly heavy in my hands.
“What’s the matter?” Darcy asked, “You have your license, right?”
“I can’t drive stick,” I told her, sadly.
“Psh, it’s easy,” Darcy said, “You’ll learn it in like, five minutes, tops.”
She pushed me into the driver’s seat and climbed in on the other side. In a tone that was oddly reminiscent of my lessons from earlier that morning, Darcy explained to me how to drive a car with three pedals. Then she patted my head and gestured for me to go.
I got it started OK, but when I tried to accelerate forward, the car juddered violently and stalled. I gave my sister a helpless look, but Darcy pursed her lips and gestured for me to try again.
On the third attempt, I got the car out of the space. Once it was going, it was easier to shift into second, then third. Then we got to a stop sign. I wanted to roll it, but there was a car in the other direction, so I stopped fully.
Again, when I tried to start, Darcy’s Jetta cut out. I swear, I could feel the car’s hatred of me, just begging to go back to its real owner.
Darcy showed me no mercy though. With a line of cars behind me honking like crazy, I was finally able to get us moving again. I said a prayer to the driving gods for no more stops the rest of the way home.
