Fooled into Bed with My Sister

[neerathemall]

We showed up at Melissa's house early, to help out with preparations.
"Hey guys," she greeted at the door, enthusiastically hugging both of us. "Wow, you guys look hot tonight."
Anna wore a light blue dress that ended just above her knees and was partly open in the back. I had to agree with Melissa's assessment. She did look hot. I wondered if she was wearing the black lingerie underneath.
Melissa herself wore a black dress, different in style to Anna's. It hugged the form of her body tightly all the way down to where it ended, a bit higher than Anna's, and it displayed a fair bit of cleavage.
I wore khakis and a nice gray shirt, rolled up to my sleeves.
"So, what can we help with?" I asked after hanging my jacket on the coat rack. "Anything that needs to be set up?"
"Yeah, a bunch of stuff," Melissa said, then paused to look at us suspiciously.
"What?" Anna asked.
"You're not going to prank me, are you?" she asked, eyeing us suspiciously.
I sighed. "No. We promised we're not doing that any more. Not since last year."
"You better not," she said. She gestured widely, spreading her arms. "This house is a prank-free zone, got it?"
"Come on, Melissa. We promised," Anna assured her, looking sympathetic. "We didn't think you'd take it so seriously."
"I put that shit all over Facebook. Do you know how long it took to get people to stop asking about my modeling career?" She grimaced, no doubt remembering the humiliation.
"...sorry," Anna mumbled.
"Bah! Forget it. I'll get you back some day. You won't see it coming," she announced, holding up a finger for emphasis.
"We'll look forward to it," I assured her. Smiling and patting her shoulder as I passed. My sister and I were April Fools veterans after all. No one in our family trusted anyone on that particular day.
"Where do we start?" I asked.
"Mmm... Anna, you handle snacks and Sam, come with me." She turned around and grinned mischievously towards me. "I need a strong man to move the furniture. I'll point, you lift."
I worked under Melissa's supervision, following her directions. Tables had to be moved and more chairs had to be carried down from upstairs. Melissa helped by complimenting me on my physique and excellent carrying technique.
We placed snacks and drinks in their assigned places around the rooms and checked that the sound system worked. We finished well before the first guest arrived.
