One evening, I was passing Darcy's house after giving my little brother a ride somewhere, and stopped by on a whim. Cheryl answered the door.

"Is Darcy home?"

"No..." She answered slowly, looking me up and down like she was trying to memorize what kind of pants I was wearing. "But she should be home real soon. Come on in and wait." She looked me in the eyes and smiled-- a little playfully, I thought. She threw open the door and hurried into the living room, without giving me a chance to hesitate.

"Sit down here," she said, gesturing at the couch, the same couch Darcy and I had first made out on. "Do you want a drink?" She asked, stalking into the kitchen without looking back, giving me a long view of her shapely backside tightly sheathed in faded blue denim.

"Sure," I answered, even though I wasn't sure if that meant an alcoholic drink, or just a water or something. Cheryl was at least six or seven years older than me and quite good-looking, and I have to admit I was a little intimidated. She kept the conversation going while she was in the kitchen , but I nervously stayed glued to the couch, a good little boy obeying his older sister's orders. After a few minutes she came back with an amber-colored fizzing drink in a tall glass in each hand, gave one to me, and then sat down on the couch so close our arms brushed against each other.

"I hope you enjoy it," she said, and laughed, taking a big swig out of her drink and smirking at me.

"Oh, it's great," I almost gasped after gulping the stiff cocktail. "What is it?"

"Bourbon and soda. Ever had one before?" she asked skeptically.

"Sure," I lied, very conscious of how close she was sitting. I began to make awkward small talk with her, and she started to pet my thigh. I almost gasped again.

"Am I making you nervous? Oh, I am. How cute!" She laughed again, and I realized this wasn't her first drink of the afternoon. I started to stutter something, but she cut me off while stroking the inside of my thigh and blood began to flow to my nether regions. "I've heard you and my sister together a couple of times and it sounds like you give her a real good pounding." She stared intently into my eyes. "I want you to do me a favor." She looked down and noticed the obvious effect she was having on me. "Oh wow! It's getting hard already!" she exclaimed, laid her hand over my erection, then looked back up. "I want you to show it to me."

I couldn't believe what I was hearing, but wasn't about to miss this chance. "Isn't Darcy coming home soon?" I asked, and she shook her head and squeezed my growing trouser snake.

"Not for a while. She took Mom to the beauty parlor and then they were going to get something to eat. They won't be home for at least an hour."

"Then go ahead and look, " I answered, and leaned back, arching up my bulging crotch a little as I took another sip from my drink.

Grinning like she'd won a big contest or something Cheryl set her drink on a side table, kneeled in front of me, and shimmied up in between my legs, her painted fingernails plucking at my buttoned fly. “I just love long, young cocks.” She pulled my jeans open, then reached inside my boxers and pulled out my swollen salami. Cheryl chuckled. "That's a beauty. I'll bet my sister doesn't even know what to do with this monster."

I didn't say anything. Without another word, Cheryl slurped me into her eager mouth. And man, could she suck a mean dick. Like a pro. Her pouty lips wrapped around the end of my dick while her hands gripped the shaft, stroking gently along my length. Pulling my pants and underwear down to my ankles, she proceed to lick my balls for a moment, then moved back to my throbbing bone. Her head bobbed up and down, slowly picking up the pace. After a minute or so, she lifted her head up, continuing the pumping motion with her hands. "Jesus Christ, you're getting even bigger." My eyes were slitted and my breathing was becoming heavier.

"Oh no you don't. You're about to cum, aren't you? You'd better not. I've got plans for you," she announced, then stood up and took off her clothes. Her breasts were smaller than Darcy's, but her body was firm and slender, with narrow hips and a little heart-shaped ass. She climbed on the couch and got on all fours, her shapely butt raised and facing me. She turned her head back to look at me and winked. "I'm sure you know what to do, big boy."

My dick sure knew what to do. I knelt behind her upraised ass and slowly wormed my tool into her glistening pink gash. She was pretty wet, and I was as excited as I'd ever been in all my sixteen years, nailing my girlfriend's older sister doggy-style. It took at least a half dozen strokes before I was plummeting my full length into her, and she started making wild moaning sounds a lot like Darcy made. Her head was whipping around in time with my stokes which were rapid and forceful. I had a firm grip on her hips so I could control our rhythm, driving myself all the way into her faster and faster with growing momentum.

"Oh, that's it! Give it to me, give it to me. Harder! Harder!" Cheryl's ass in my hands was rocking back hard on my erection, the ass cheeks slapping up against my upper thighs and hip bones, our juncture making obscene slurping sounds.

"Cum in me! Cum in me!" Cheryl was yelling. Damn... maybe no one else was home, but I bet everyone in the neighborhood could hear us. Finally, I did cum in her. Wave after wave seemed to pass through me before I collapsed on her back, and we both lay there for a few minutes, panting and sated.

Cheryl eventually pushed me off her. "Goddamn, you're heavy." She quickly picked up her clothes and seemed angry. "It feels like I got a gallon of sperm in me. Boys are so messy." Starting to put her clothes back on, she looked at me lying on the couch, my pants still down around my ankles, and frowned. "Hurry up and get dressed. You got to get out of here before anyone sees you."

So I did. I pulled up my pants and left. Of course, I never said anything to Darcy about it, and when I did run into Cheryl, she acted like it never happened. I nailed her one more time, about six weeks later, when Cheryl called me over while Darcy was at work. It was just as frenzied and sudden as the time before, but I have to admit, it was fun fucking a woman who really knew what she wanted. But honestly, it was mostly Darcy and her big titties I lusted after and enjoyed.

At the end of the school year, Darcy graduated, and I moved to California with my family. I was heartbroken. I thought I really loved her. What a naive fool I was.

I called Darcy once or twice from California. She had a job as a waitress at a truck stop. What a job for a slut, huh? I never saw her again, and have no idea what happened to Cheryl. But in liberal Northern California, my fortunes were definitely improving.
