Mom and Dad are both teachers and had a teacher convention to attend out-of-town. Before they left, Dad had put my stepsister, Doreen, in charge since she was a sophomore in college and I was a seventeen-year-old high school senior. I was given a list of what needed to be done in the yard and Sis had to keep the house neat and clean. That meant I’d be helping her on top of what dad had given me. The idea of 'Being home alone with Dory' really didn’t sit well with me.
After they left, I headed outside to get started on the yard work, while Dory got busy cleaning in the house. It was unusually hot for a spring day and I took off my T-shirt. As I mowed the lawn, I glanced over at the picture window and my jaw dropped as I watched her cleaning the window. She was wearing a pair of cutoff blue jean shorts and a white crop top with a plunging neckline. Her voluptuous breasts were on full display, every delectable curve. Her long brown tresses draped over her shoulders, dangling in front of her shirt.
I looked away quickly, hoping she didn’t see me staring as she swayed to the music from her headphones. I must admit, it was difficult concentrating on the task at hand as I occasionally glanced over to see her stretch and bend. It seemed as if she knew I was watching. By the time I finished mowing the front yard, I needed to adjust the stiffness in my athletic shorts. I reached inside my shorts, made the adjustment and glanced at the window before heading to the backyard. She had finished cleaning the window and was now pushing the Hoover.
Just as I was about to go get something to drink, out came Sis with a pitcher of pink lemonade. “Hey Paul, come and have something to drink,” she said, walking over to the table on the patio.
As I walked over, I couldn’t help notice she had pulled her hair back in a braided ponytail and her nipples were visible in her top. I walked over and took a seat; she poured a glass for each of us and handed me one. Being so thirsty, I chugged it down in several big gulps.
“Mmm, that did the trick; thanks, Sis,” I said as I reached for the pitcher.
“Let me get that for you, Bro,” she said, grabbing the pitcher and reaching across to fill my glass as I held it.
“Thanks,” I replied, checking out her taut nipples and the deep valley formed by her ample tits.
She said nothing when she sat back as I took a sip from my glass. After a very uncomfortable moment of silence, she stood, looked at me, smiled and seductively ran her tongue across her bottom lip. When she turned to go back in the house, my eyes zoomed in on her firm heart-shaped derrière. Reaching the door, she turned her head and in a sultry voice, said, “I’ll see you when you’re done.”
I sat in total shock and not sure what to make of her behavior. She had been teasing me for several months with her innuendos and her choice of clothing. After contemplating the events up to now, I stood and adjusted my now-renewed, stiff cock.
I took another hour to finish mowing the backyard, pulling weeds and adding mulch as needed. By the time I finished, it was late afternoon, and I felt drained and horny as I headed to the house. Going straight to my room, I stripped off my shorts and wrapped a towel around my waist. I grabbed my swim trunks and went to take a shower. Nearing the bathroom, I heard moaning above the running water and took a peek.
What I saw had my stiff cock twitching and throbbing; there was Dory’s silhouette visible through the steamy glass door. Standing there, I watched as her hands rubbed the soap over her big tits, down her body and back up. She moaned as her fingers played with her nipples and pressed into the soft flesh as she squeezed her tits. One hand moved between her legs. I stood there and watched as she moaned out, “That’s it, Bro, fuck my pussy!”
Her body jerked several times as her orgasm ripped through her. I went back to my room and waited for what seemed like an eternity. Finally, I walked out of my room and toward the bathroom. As I got closer, Dory emerged and was coming toward me, wrapped in a towel that barely reached mid-thigh. The tops of her boobs squashed together, and I felt my cock pushing against the towel. I hoped she hadn’t noticed and as we walked by each other; she gave that smile again before going into her bedroom. I entered the bathroom, undid the towel and placed it and the trunks on the sink before entering the shower.
The cool water felt refreshing as I soaped up my body and I thought of what I witnessed. After several moments of nipple pinching, I slid one hand slowly down my chest. Reaching my throbbing cock, I wrapped my fingers around the thick shaft and a soft moan escaped my mouth. I began a slow up-and-down motion, lightly squeezing the shaft. Reaching the mushroom head, I rubbed gently and smeared the pre-cum around the smooth skin. My breathing quickened as I pumped the blood-engorged shaft.
Thoughts of seeing her in the window and then in the shower put me over the edge. The first two loads shot out across with such force that the ropes of cum hit the wall in front of me. As my balls emptied, I leaned against the opposite wall and saw that my hand and stomach were covered in thick gobs of cum. I quickly washed up, hoping Dory hadn’t seen or heard me. After drying off, I put on my swim trunks and headed out to the pool.
