Ashley was going so slowly, but I still couldn’t last. I said, “I’m about to-” I didn’t finish the sentence, but I knew she knew what I meant.
She broke off the kiss with our brother and said, “Fill me up, Alex, fill me up with your seed. I want to feel you spasm inside me.”
In another second, she got her wish. Abandoning the slow movements, my hips started thrusting powerfully, and my cock exploded deep within her, coating her insides with my creamy goo. She moaned and pushed back at my suddenly strong thrusts, grunting with every spurt I shot her with.
She said, “Alex, you’re making me-” She didn’t finish the sentence, and I could only hope I knew what I was making her do. The mere thought that I was giving her pleasure extended my own orgasm by a few spurts.
She kept pumping me fast and hard after I’d shot my load, and I kept pumping right back in her. In another moment she moaned deeply and said, “I’m . . . I’m . . . Oh, oh, oh,” words failing her for once.
Josh didn’t let her finish before he took drastic action. He pulled her off of me and tossed her lengthwise on the couch, face up. I moved out of the way, onto the floor right in front of her. I couldn’t help but notice some of my cum drizzling out of her, but not for long. She was still squirming and moaning when he jumped on top of her and stabbed his rod inside her, thrusting hard and fast, just as I had. She pushed back at him too, continuing her stream of unintelligible syllables, extending her orgasm as he brought himself to the brink.
It took no time at all before Josh was grunting maniacally, the dimples in his butt deepening and receding, and I could tell he was pumping his load inside her. He moaned sharply with every thrust, six or eight or ten times, and she moaned right back with him, with just as much intensity. Only then did his movements begin to slow, their breaths start to return to normal. After the panicked thrusting stopped completely, he stayed inside her, gave her a tender kiss. “You’re my favorite sister, Ash,” he said.
“And you’re my favorite bro-” She caught herself before finishing the sentence. “And you’re one of my favorite brothers, Joshy.” Then she turned and looked at me on the floor. “You’re my other favorite brother, Alex.”
“You’re one of my favorite sisters,” I said, and to my delight, everyone laughed with me. Emboldened, I leaned up and gave her a kiss on the lips. Maybe it was anticlimactic that my first kiss came after my first sex, but you wouldn’t know it by the way it felt. Our lips engaged like we’d been lovers forever. Her lips were so soft and warm and wet. When I felt the most gentle probing of her tongue, I gave her mine as well. A perfect kiss in that perfect moment of calm after a stunning orgasm. It was perfect even though my brother’s cock was still inside her. It was even more perfect because my brother’s cock was still inside her. We both loved her, we always had, we always would. She loved both of us.
Josh said, “Alex, can you do us a favor? Bring my T-shirt over here.”
I ended the kiss with my sister and looked around at the pile of clothes on the floor. I spied his shirt and brought it to him as instructed. “Here you go.”
“On the count of three, Ash is going to lift her butt off the couch, and I want you to put my shirt underneath us. Got it?”
“Yeah, ok.”
“One. . . . Two. . . . Three.” They both raised themselves up and I quickly slipped his shirt under them just as planned. As a bonus I got a nice feel of her rear end as I was straightening it out. When I was finished they fell back onto the cushion. I rested my forearms on the edge of the couch and held my head so my chin was touching my wrist and my nose was touching Ashley’s hip.
So I had a very close-up view when, with the shirt in place, Josh slowly tugged himself out of her, his member soggier and floppier than I’d seen it all day. As soon as he broke off contact, a blob of liquid streamed out of her, leaking down her body and landing on the T-shirt. I was so entranced by this display that I reached a hand out toward her, feeling the stickiness of the goo as the drizzle slowed. My reluctance to explore her body had diminished, and I let my gooey fingers feel her lips, inside and outside, everywhere I could reach.
In a minute I moved my hand and she sat up, using the T-shirt to mop up the dregs of the liquid. She pulled the shirt out from under her, holding it up for both of us to see.
“That’s quite a wet spot,” she said.
“Twice as much as usual,” Josh said.
Feeling the cushion, she said, “Oh, it soaked through. There’s a wet spot on the couch too.”
“No worries. This isn’t the first sex on this couch and it won’t be the last.”
“So, um, this spot on the T-shirt reminds me,” I said. “What were the results of the experiment?”
Josh raised his eyebrows. “Yeah, what about it, Ash? Scale of one to ten, right? How did we come out?”
“Oh, yeah, I have the results all ready for you. You guys sit right next to each other on the couch like you did before.”
We went back to our normal spots, Josh’s leg pressed against mine just like it had been before. The only difference was our state of arousal. Both Josh and I were calm, breathing normally, hearts beating normally, and flaccid.
She knelt in front of us, just like before. Both of her hands went to Josh’s crotch and encased his limp dick between them. “This little guy, the control, was extremely slick. Rating nine point three.”
“That’s more precise than I was expecting,” said Josh.
“Qualitative can still be accurate,” she said.
She took her hands away from Josh and held my dick. “This little guy, the experiment, was a new one for me. It was also extremely slick. Rating nine point eight.”
Josh and I made eye contract just as the verdict was announced, and we both smiled. “Really?” he said. “Alex, congratulations.”
“Aw, shucks,” I said. “It was nothing.”
“I thought of another factor that might influence the results. I think whoever goes second might get a higher score.”
“Maybe,” I said. “If so, I lucked out.”
“No, Alex, you don’t understand. We have to control for this. I think the only way is to do the experiment over, but in the reverse order next time.”
I figured he was just kidding, but I got a jolt of anxiety in my chest anyway at the thought of doing it again. Making love to my sister again. Giving my sister an orgasm again. The jolt of anxiety turned into goosebumps down my arms.
Ashley was still fondling me, feeling my balls, inner thighs, not shying away from my knob either. “Good idea, Joshy. See, this is why I love you. Solving science problems.”
“At your service,” he said.
She put one hand around each of our cocks, just holding our floppy members between her fingers. I wasn’t turned on, but I also didn’t want it to end. “So Alex,” she said, “I guess we can do more experimentation when you move in with us in the fall, right?”
My living arrangements had been the farthest thing from my mind, but I quickly changed gears. What I learned and what I did that morning were changing my opinion about living in the little house. “Yeah, sounds like fun. I can’t wait, actually.”
“We’ve been wondering how to tell you that Josh and I share a room. Which means there’s a room for you too.”
“Hey, Ash, I have an idea,” Josh said. “There’s room for Alex in our bed.”
report I turned to look at him and we made eye contact again. A broad smile creased his cheeks.
She said, “Josh, what a great idea! I can wake up with both my favorite brothers every morning!” I barely had any mental energy left, but even still I tried to visualize what it would be like to wake up with her in the same bed as me. Those sexy breasts just an arm’s length away. “Oh, and as a bonus, we can turn the extra room into a giant closet!”
You might think the most memorable part of my day was the horrific embarrassment of my first orgasm, or the unimaginable joy of my second. Or you might think it was resolving my living situation in a way that promised many more. But you would be wrong. Two moments from that day that will stick with me forever:
First, this was the day that permanently made me aroused by the word labia. The word did nothing for me before, but ever since then, I’m hard the instant my sister puts her lips at my ear and whispers, “Labia.” I’m instantly transported to the moment when she lowered herself on me and I felt her labia on my straining cock for the first time.
Second, I will never be able to drive past a Y-Mart and see the giant logo on the sign in the parking lot without remembering the logo on Ashley’s shirt, which she carefully used during the experiment first to carefully pat dry Josh’s rod, then mine, and then, yes, her labia.
