“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.
“Ta, for all your help, David,” Dad said as I was pounding in the last nail on my side and he was putting tools away in the toolbox.
“Nothing like two big, strong, sweaty men working on a project.” Dawn shaded her eyes as she looked over at us. She was grinning.
“Cheeky.” Dad smiled fondly at her. Jesus. If he had any idea! My mouth went dry at the thought.
“I’m going to need a shower.” I stood and arched my back. It hurt from being bent over so long. “Mind if I go, Dad?”
“Go ahead.” He was closing up the shed. I was pretty sure my porn collection was safe from prying eyes, but I was clearly going to have to find a new hiding spot.
Dawn smiled at me as I passed, nudging me with her toe, but I ignored her. I was going to go jerk off in the shower and come all over the wall as I imagined fucking her so hard she screamed-but I wasn’t going to let on.
I ran the water in the shower, stripping as I waited for it to get hot. My cock was still hard-it felt like I had been hard for hours. The thought of Dawn’s exposed pussy, her teasing smile and that little “o” of her mouth, had my erection aiming skyward the minute it was free from my boxers.
I stood holding it in my hand, squeezing it, trying to appease it a little and ease the ache as I adjusted the water temperature. The hot water felt incredible and I stood there for a minute, just getting wet. Every time I closed my eyes, I could see my sister’s cunt, her thick lips and pink centre.
I washed my hair, but my hand seemed to have a mind of its own as it snaked down to my cock, pumping it gently as I remembered how she looked as she fingered herself. Jesus, but she was hot. What would it feel like to fuck her, I wondered? What would it feel like to slip my prick between those fat lips and sink deep inside of her? My hand moved faster at the thought.
“David?” The knock on the door made me jump. It was Dawn! “I have to pee!”
Oh Christ. We only had one washroom. “Okay,” I called. She opened the door and came in. The shower curtain was pulled tight, but I could hear her peeing, and the sound was strangely erotic. My hand moved even faster.
“Don’t flush!” I reminded her. If she did, I’d be standing under a well-needed cold shower.
“I won’t.” She peeked around the curtain.
“Hey!” I jumped, my hand moving immediately away from my erection.
I flicked water at her and she grinned, pulling the curtain aside and stepping in, completely nude. She looked down at my cock, which hadn’t flagged in the least. I stared at her in shock, but she nuzzled up to me, sucking at the skin of my neck and pressing her sun-warmed, oily body against mine.
“You know you want to.” She hooked her leg around mine and ground her cunt against me. My cock was trapped, pressed into her belly.
