Michelle bobbed her head up and down, taking a few inches of me into her mouth at a time before pulling back while sucking harder. Hell, she hadn’t even KISSED me since finding out Alex and I were banging. Now she had her lips pressed against a significantly more intimate part of my body, and I never wanted this feeling to end.
But you know what they say about all good things. My hands were tangled in her hair, and when my fingers suddenly clamped down onto her skull, she knew I was about to blow. My little sister pulled her head back until only my mushroom head remained inside her mouth, and she pumped my shaft furiously with her right hand.
“Chelle!” I moaned as I came, both testicles uncorking and firing away. Michelle’s mouth was flooded in an instant, but she swallowed quickly and readied for more. My hips bucked five or six times, each heralding a fresh wad of cum to go straight into my teenaged sister’s belly. And finally I collapsed, feeling like my spine had been forcibly withdrawn from my body while Michelle kept my prick in her mouth, suckling out every last drop to ensure nothing would spill out on the sheets.
I lost track of time after that. I didn’t fall asleep (I think), but I was certainly out of it for a little while, awash in my post-ejaculative glow. I realized Michelle must have gotten my boxer shorts from somewhere, perhaps even retrieved a fresh pair from the drawer, because I found myself tucked into my underwear by the time she pillowed her head on my shoulder once more.
“You tasted like pussy juice when I got started,” Michelle muttered with a smirk as she looked up at me with those big, beautiful eyes. “And I don’t usually like swallowing. I think I’ve only ever done it like ... twice. But like I said, I didn’t want to make a mess in the sheets. And there’s something so deliciously ... naughty ... about the idea of swallowing my big brother’s cum.”
I grunted wearily, “I’ll have to take your word for it.”
Michelle frowned, and in a concerned voice she asked, “Did you not enjoy that? I’m not the most experienced cocksucker. I’m sorry if I couldn’t ... uh ... please you the way some of your girlfriends could. Or even Lex. I—”
I shushed my little sister with a finger to her lips. “What the hell makes you think I didn’t enjoy that?”
“Well you didn’t seem all that enthused a second ago.”
“I LOVED it. I’m just tired. You wiped me out, Chelle. But please don’t doubt that I enjoyed it.”
Michelle screwed up her face. “I think I’ll ask Lex to give me lessons. So I can be better for you.”
“You were great,” I reassured her.
“Guys’ll say anything after you’ve let them cum in your mouth.”
I chuckled. “That’s probably true.”
“So I’ll have to ask you again in the morning when the blood has returned to your brain.”
“I’ll give you the same answer I’m giving you now.” I sighed and reached up to caress my sister’s cheek. “You were wonderful. Thank you.”
She didn’t look like she wanted to 100% believe me, but she accepted my answer for now. Sighing again, she craned her head forward and gently pressed her lips to mine. I pressed my lips right back, and moments later she pressed harder and parted my lips to push in her tongue.
It was our first real kiss.
We made out for a little bit, her taste just a touch salty. But eventually she pulled away and set her chin down on my chest, murmuring, “I love you, big brother.”
I smiled and caressed her cheek once more. “I love you, too.”
Chapter 4: Love
Lest you think the relationship between me and my little sister snowballed from there and we started sucking and fucking every chance we could get, let me assure you that didn’t happen. In fact, despite stating an interest in getting blowjob lessons from our big sister, it would be another week before she even put my dick into her mouth again.
Michelle continued to sleep in my bed every night, although she now arrived before I went to sleep instead of slipping in beside me in the middle of the night. When I told Alex what we were doing on Monday morning, my big sister couldn’t seem to make up her mind whether she should initiate our incestuous hookups BEFORE bed to ensure she didn’t encroach on Michelle’s cuddle time, or deliberately arrive LATER at night so that Michelle would be forced to watch, run away, or maybe even join in.
Alex’s eyes glittered at the idea of her baby sister joining in. I certainly got harder at the idea. And that’s how Alex started giving me a handjob right there on the couch, which turned into a blowjob, which turned into climbing into my lap and fucking me right then and there. Michelle wound up yelling from the top of the stairs, “Will you two keep it down! I’m on a fucking Zoom call and I don’t want my entire class hearing my siblings having sex in the background when I go off mute!!!”
We got quieter. We didn’t stop fucking or anything, but we got quieter.
One thing that changed over the course of the next week is that Michelle and I started spending a LOT more time together. While we had always shared mealtimes, played games together, and had our evening workouts, the bulk of our days had been typically spent on our own. I would play video games, watch Pornhub, and surf the internet. Michelle would chat with her friends, read books, and ... whatever. But now that previously “independent” time became additional “together” time.
Seriously, other than attending Zoom classes, Michelle and I spent all our time together. Instead of doing her homework in her own room Monday afternoon, Michelle brought her laptop to my room and sat on top of my bed, silently doing her work while I silently did mine at my desk. Three times, she asked if I could take a break, inviting me onto the bed so that she could wrap her arms around my neck and kiss me like there was no tomorrow.
It was nice.
I didn’t paw at her breasts or otherwise attempt to initiate anything sexual, although I’ll admit to grabbing her ass quite a bit. We made out for about ten minutes at a time before returning to our work, and I have to admit it was the most enjoyable time I’d ever had while doing schoolwork. So the next day, we did the same. And the next day. And the next.
The dress code also slackened quite a bit around the house. Michelle started going bra-less as soon as classes ended, advertising her arousal with perky nipples that dented the front of her thin shirts. Alex’s big tits needed a little more support, but she started skipping her bras every now and again as well as a way of teasing me while also advertising her intention to seduce me sooner than later. And don’t get me started on the way the girls stopped wearing pants or shorts every now and again. Twice, Alex didn’t even have panties on underneath her oversized shirts.
Even when not doing schoolwork, playing games, or watching TV, Michelle remained glued to my side. We ordered in-line skates and Michelle asked me to teach her, which added almost an hour a day together. I stopped playing video games and had already stopped watching Pornhub. She texted her friends but no longer wasted hours chatting with them. Instead, we’d sit on the couch talking about ... whatever. Or we’d cuddle in bed talking about ... whatever. And if the conversation ever started to wind down, one of us would pucker up to start a new makeout session that would last until ... whenever.
Michelle started saying “I love you” a lot more. I was happy to return the endearment, and initiated the phrase a few times myself. She always glowed whenever I did that. She also started getting a lot more touchy-feely around me. When watching TV, she’d lean against my side and pull my arm around her shoulders or midsection. Alex, of course, had already been doing so, so whenever the three of us were watching together I found myself happily in the middle of a sister sandwich. In the kitchen, Michelle started grabbing my ass as she passed behind me. Turnabout was fair play, so I happily did the same. Once, I even slid my hand into the back of her shorts and got a palmful of bare buttcheeks. Michelle squealed, spun around, and slapped my hand. I immediately got nervous that I’d crossed a line, initiating a higher level of intimacy that she wasn’t comfortable with. But as soon as she got over the surprise, my little sister turned around, thrust her ass at me, and intoned in a husky voice, “Do it again.”
