“Come on, Dad.” I set the boards on the ground between his toolbox and the planter. “Let’s get this project started!”
Dawn was silently laughing, her belly and breasts shaking as she covered her mouth so Dad wouldn’t hear her. I gave her the finger and she made a wanking motion between her legs, sticking her tongue out at me.
I’d been so panicked about the possibility of Dad finding my porn collection that I’d barely noticed her in her white bikini, but now the motion of her hand between her legs drew my eyes there and I found myself staring.
“Alright, Davey.” Dad slapped me on the shoulder as he came out. “Let’s get to work!”
At that point, I was just thankful that no one was poking around the shed anymore and I was pretty much willing to do anything. Dawn laid back down to soak up some sun, and Dad and I got to work, pulling apart the old planter.
Mum hadn’t planted anything in it this year, because the wood had rotted, so we didn’t have to worry about that. The wood had split in several places, though, making it harder to pull apart. I was using the claw end of the hammer at one end, and Dad was at the other, trying to pry the nails up.
“Next time,” I grunted, wiping sweat off my brow with the tail end of my t-shirt. “Don’t use such long-arse nails!”
Dad yanked a nail free and it tinkled on the cement. “Come on.” He started on another one, grunting with the effort. “Don’t be a nancy boy. Just give it some welly!”
“Yeah!” Dawn called, dropping her sunglasses and looking at me. She had that Dawnie-grin on. “Give it some welly, David!”
“Nosey Parker!” I made a face at her and grabbing my hammer, starting to work on the board again. By the time we got the back taken off, I was sweating like mad, and I pulled off my t-shirt. Dawn whistled and I threw her a dirty look.
“Come on, go starkers.” She grinned. “No one can see.”
“Good thing.” I tossed my t-shirt at her. It landed shy of her chair. “You might as well be, in that thing.”
Dad glanced over at her, frowning. “The boy has a point.”
“Oh, naff off, both of you!” Dawn turned over on her belly on the lounge chair. Her bikini bottoms pulled across her arse, and I could actually see the outline of her lips in them. She swung her feet, not looking at us, her body glistening with oil. I noticed that she was actually getting a little more brown.
“Don’t get cheeky, Miss.” Dad tossed aside the old boards and headed toward the shed.
“Whoa! Ho!” I grabbed his arm. “Hey, Dad, where are you going?”
He looked down at my hand on his arm and back up at me, his eyebrows raised. “I need my saw,” he said slowly, taking my hand off his arm. “Are you all right?”
I nodded, my eyes shifting to the shed. “Fine.”
“You’re a bit wonky today.” He frowned, setting off toward the shed.
My jaw was clenching and unclenching as I sat on one of the patio chairs, waiting for him as he rummaged around in there.
“What’s the matter, little brother?” Dawn smiled over at me. “Afraid you’re going to get caught?”
I glanced over at her and saw that she had turned onto her back and was tracing the outline of her nipples through her bikini top. They were hard and poking through the material. My eyes nearly popped out of my head.
“Dawn!” I hissed, glancing toward the shed. I could still hear Dad sorting through things in there. I was just praying he didn’t go near the boards again.
“What?” She pinched her nipples through the material, making them even harder, and I could feel my cock responding, remembering how they felt in my mouth, how they looked when she was sitting up on the counter, letting me fuck her with the cucumber. Holy hell.
“Fancy these?” She lifted her breasts, rubbing her hands over the material. She slipped one hand under the white cloth, from the top, and I could see her working her hand over her bare skin.
I watched, transfixed. She pulled her bikini top down over her breasts completely then, shaking her shoulders, making her breasts sway. I stared, my cock an iron rod in my jeans now, my breath caught in my throat.
“Dawn,” I gulped, glancing toward the shed and realizing I couldn’t hear Dad anymore. She smiled, pulling her top back up and stretching her arms over her head with a fake yawn as Dad came out of the shed carrying a saw.
“Damned thing was hiding,” he mumbled, calling over to me. “Come hold this steady, David!”
“Coming…” My voice was faint as I stood. She was staring at my crotch and I flushed, knowing my erection must be clearly outlined.
I went over to help Dad, but I couldn’t help looking over at my sister. She was watching us, lying back on her elbows, her feet pressed together, her legs open. The outline of her pussy under the material was making me loopy. It was all I could think about.
Dad was sawing a board that he’d put up onto a breeze block, and I was supposed to be holding it steady. His back was to my sister, but I was facing her, and had a clear view of her full body, lying there glistening in the sun. She saw me watching her and grinned, and I inwardly groaned, but I couldn’t look away as she started teasing her nipples again.
Dad sawed through that board and began measuring another, his back still to my sister. She continued to tease me, pinching and pulling her nipples through the material, making a little “o” with her mouth.
“Hold this.” Dad put another board up. I put my knee on it, my eyes on my sister’s body. She was rubbing her hands over her belly, sliding them lower and lower. I licked my lips as I watched, my cock throbbing in my jeans now.
Dad was sawing away, grunting and wiping sweat from his brow. The sensation made me think of fucking, and I couldn’t help but think of fucking my sister. I had the brief fantasy of just pulling her bikini bottoms aside and plunging my cock into her right there on the lounge chair-that’s how much I wanted her.
Dawn slipped her fingers under the top elastic band of the bikini bottoms and I watched, wide-eyed, as she began to play with herself. I could see her hand working underneath the material, and I remembered exactly what she felt like inside, how soft and smooth and warm.
She saw me watching her and grinned, pulling the material aside with one finger and showing me her cunt. I glanced down at Dad, who was still sawing away, and then back to my sister, exposing herself to me. She was the most beautiful thing I’d ever seen, lying there with her cunt spread open, sliding her fingers up and down her slit.
When she started fingering herself, I lost it. I think I was unconsciously leaning forward, to get a better view, because my knee slipped off the board and it went flying up, nearly hitting me in the bollocks.
“Flippin’ ‘eck!” Dad looked at me with a frown. “David, will you concentrate?”
“Sorry.” I glanced back at Dawn, who had stopped playing, but was now licking her fingers. Oh God. I could almost taste her pussy. She grinned at me and blew a kiss. My whole body felt flushed and I was grateful that it was hot out.
I tried to keep my mind off my sister and just pay attention to helping Dad. We got the rest of the boards cut, and Dawn rolled over onto her belly and thankfully appeared to fall asleep. Her sunglasses were askew, and she was drooling onto the towel underneath her, her hand trailing down onto the patio. Her bikini bottoms were riding up her sweet, rounded arse, and I wanted to touch her so badly it almost hurt.
I grabbed a hammer and started pounding along with Dad, helping him nail the boards along the back of the planter. I pounded as hard as I could, hoping if I expended enough energy, I might eliminate the throbbing ache between my legs somehow.
It actually seemed to have the opposite effect, especially when my sister rolled onto her back again, throwing her arm over her eyes and giving me a clear view of her rising and falling breasts, the material pulled taut over them.
