After we were done, Darcy went right up to her bedroom. I was exhausted from the day, so I followed her up and lay down in my own bed. I picked up my iPad to read myself to sleep. I thought it was over, but then I heard Darcy’s phone ringing distantly. A moment later, my door popped open and Darcy slipped inside. Her hair was up and off to the side, clearly unsettled by sleep.
My older sister yawned, pulled off my covers, gave me a quick BJ, then left the room. It was the most clinical sexual experience I’d ever had. I fell asleep soon afterwards.

I woke up to the usual sight of my sister, but she wasn’t dressed in her usual tank and panties. Instead, she was wearing tight dark shorts and a pink t-shirt. She stood at the end of my bed and started to stretch.
“Come on, bro, day’s waiting,” Darcy said. I looked over at my phone. It was 6am. Even my parents would be dead asleep at this hour.
“Don’t care,” Darcy said, “Time to go.”
I sighed and stripped off my pants. My cock lolled lazily on my leg.
“Not that!” Darcy said. “That’s for later. Exercise first.”
I groaned and got up. I saw Darcy had already gone through my clothes and laid out a pair of shorts and a t-shirt for me, plus my socks and sneakers. I got dressed, unsure if I was awake or dreaming. Then my sister dragged me outside.
“We’ll start slow,” Darcy said and took off. I tried to keep up with her as best I could. Like I said, I wasn’t in bad shape, but I wasn’t running every day (or every month) either. After the first ten minutes, I started panting. After the first twenty, I started dying. But Darcy wouldn’t let me stop.
Finally, after we’d gone around the block about four times, my sister stopped in front of the house. I stood over our newly planted tulip bulbs and retched. Darcy stood next to me, bouncing happily on her heels.
“We’re doing this every day from now on,” Darcy said, “It’s part of our routine.”
I nodded, defeated. I limped up the stairs and into the shower. Darcy showered after me. When she was done, she came into my bedroom wearing a tank top and yoga pants, her hair up in cute girlie pigtails.
My sister pulled me to the edge of the bed, then knelt in front of me. She didn’t even say a word, just sucked me off. It was another one of Darcy’s weekend morning blowjobs, slow and sensuous, teasing and taut, till finally I emptied myself into her waiting mouth.
Darcy gulped it all down, then clapped her hands and jumped onto my bed.
“My turn!” she announced and stripped off her bottoms. She spread her legs lewdly and lay back.
I reached over to touch my sister’s quim, but she pushed my hand away.
“I think you’ve gotten enough oral to return the favor,” Darcy said. I nodded. She was right, of course. I climbed between my sister’s legs and put my head up to her sex. I could smell her from the source this time and it was stronger, heady. Yet also disturbingly familiar. I wasn’t supposed to know this scent, and for a moment the old feelings of wrongness roiled in my stomach. I pushed them back down.
Tentatively, I licked at my sister’s pussy.
“Not this again,” Darcy said. She sat up slightly and made sure I was listening. “You’re eating my pussy, not painting the Sistine Chapel. Whatever you do with your fingers, do that. But with your tongue.”
I went deeper and licked my sister, hard, from top to bottom. I sucked on her clit and tried to rub it back and forth with the flat of my tongue. When I rolled up my tongue and slid it into her hole, Darcy jumped up like she’d been shocked.
Now, not only was I smelling my sister, but I was tasting her. And, to my shock, I found I kind of liked it. I liked the way she responded to me licking her even more. I got a rhythm going. Like my sister did to me, I used my fingers and mouth to get her off.
I’d been rubbing Darcy’s clit with my tongue and pumping her with my fingers for a while when suddenly my sister grabbed the back of my head and held me there. Her thighs closed around my skull so hard I thought she might crush it like a grape. Distant, through her thighs, I heard Darcy scream. Then she fell back, limp and weak. I gave her pussy one last little kiss and her body trembled.
Watching my sister’s orgasm was the sexiest thing I’d ever seen. Full stop. Not sexy for my sister, as so many things had been before. But actually, totally hot in a way that no porn video could ever compare.
I realized that, up till then, I hadn’t actually made my sister cum. Not really. Just little bursts of pleasure. This time though, Darcy actually did go over the top. She lay back, distant, and stared up at the ceiling. She mumbled to herself and stroked my head. Otherwise she didn’t move.
“Thank you, Ethan,” I heard her say. That same strange, plaintive appreciation I’d given her before.
Gradually, Darcy rolled out of my bed. She pulled her bottoms on and got up to go. Her legs gave out, but then she stood up straight and stumbled out of the room. I got up as well, my face sticky with my sister’s spend.
When I came downstairs, Darcy was sitting at the kitchen table, staring at her phone. Our parents, miraculously, were still asleep. Thank God for lazy Sundays.
“You should make breakfast,” Darcy said, looking up from her screen.
“I think I know how to make cereal,” I said.
“Pancakes,” Darcy said, “With bacon.”
I gave her a confused look.
“There’s this new thing called the Internet. Look it up and get to work.”
I nodded, exasperated, and went into the kitchen. There was an easy recipe online and I realized we had enough in the house for me to make it. I burned the fuck out of my first pancake and none of them came out in a Euclidean shape, but by the time my parents came downstairs I’d put together a whole, mostly edible breakfast for the family. I even warmed the syrup and filled little glasses of orange juice.
“Wow, what’s this for?” Dad asked as he sat down, eyeing the food warily like he expected it to melt into a mirage at any moment.
“Ethan wanted to thank you guys for putting him up for free all summer,” Darcy said.
“I did,” I said.
“He appreciates how much you both sacrifice for him,” Darcy said.
“I do,” I said.
“In fact, he’s going to be making meals for all of us from now on,” Darcy said.
“I am?” I asked. My sister gave me an ugly glare. “I mean, I am.”
“We all work hard during the day, but since Ethan’s at home it makes sense for him to be doing the cooking,” Darcy said, “Right?”
“Ummm, yes.”
“At least until he gets a summer job,” Darcy said.
“Well I must say I’m very excited about this new attitude from you, Ethan,” Mom said.
“You know we love you no matter what,” Dad said, “But we’re proud that you’re finally helping out with the family.”
“I don’t suppose you’re going to help us with the gardening,” Mom said, “As part of your newfound responsibility.”
Darcy rolled her eyes. “We have important stuff to do today,” she said, ignoring Mom’s glare.
