Stepbrother Under Wraps(11)
This time it’s my sister’s turn to pause. “Touché. I don’t want your grubby hands anywhere near my butt. But you can’t just go and rub on me either, because that’s like totally and utterly wrong, and you damn well know it.”
“But what’s the harm if we’re both dressed?”
Ella contemplates my logic for several beats. “Huh. I suppose there really is nothing that wrong with it, at least as long as we both got our clothes on. Just hurry it up, okay? The idea’s already kinda creeping me out.”
Ella relaxes, and while keeping a cautious eye on mom and dad, I continue hunching against my sister’s warm body for a while longer. However, before I really get anywhere, my raging hard erection begins to ache painfully from being forced to bend at a bad angle in the cramped confinement of my underwear.
“Ella,” I whisper, “my underwear’s way too tight and it’s kinda making me go numb down there. Is it okay if I take it out?”
My sister’s head spins around. “You mean take out your, your... thingie?” she gasps, not willing to say the word. “Certainly not! What are you, some kind of pervert?”
“Of course not... but I don’t know what else to do! It’s really hurting me, Ella. C’mon – you know me!”
“Yeah... that’s kinda the whole problem,” she mutters.
“Look, you just said there’s nothing wrong with it if we’ve got our clothes on, so that means it should still be fine so long as you’ve got clothes on. Right?”
Ella whines to herself unhappily. “I suppose you’re right... but it’s a fine line, and don’t you dare go making a sticky mess of my tights. This is my favorite pair.”
My heart skips a beat. Was she actually contemplating that I might shoot a load on her ass? If only I didn’t think she’d literally kill me for even trying!
Fumbling under the blanket in a kind of incredulous daze, I push the elastic front of my sweatpants and tight briefs down to just below my balls, freeing my painfully hard erection from its prison and allowing it to thrust out almost perfectly straight from my groin – straight towards the soft flesh of my sister’s curvy ass. Frantically drawing Ella’s body closer to mine before she can change her mind, my circumcised cock bends up and glides along the shallow groove between her leggings-clad buttocks... our bodies now separated by nothing more than a single layer of extremely thin fabric.
Well, and also her panties, but who’s counting?
Even still, my heart is pounding so hard in my chest I can barely hear the movie soundtrack, and feel like I might pass out from the rush of blood filling my head!
Hunching back and forth against Ella’s ass very slowly and quietly so as to not alert our parents to any usual behavior, before long my sister actually wiggles her butt experimentally, wedging my cock tighter into the crack.
“So, ah... Tommy... your, uh, thingie feels pretty damn big back there...”
A proud thrill courses through my veins – along with a gush of thick precum that oozes from the end of my cock. “Well, I’ve never had any complaints from the ladies,” I whisper back.
Ella giggles quietly. “Yeah, because there haven’t been any ladies!”
“Statement still stands.”
“Uh huh. But it’s kinda feeling a bit damp back there, bro. You’re not making a mess of me, now are you?”
Almost certainly, I answer in my head. “I have absolutely no idea,” I answer aloud. “But your ratty old tights are starting to chafe me anyways. The underside is like a really sensitive part of a man’s, uh, penis, you know.”
“Yeah? Then if you wanna stop chafing I suggest you put it away, because I’ve decided this was a horrible idea anyways. Let’s just watch the movie together like normal.”
Stop? Now? I don’t think I could if I wanted to!
“C’mon, Ella!” I plead in a whisper. “A little more grinding won’t make anything any worse.”
“Yeah, but Tommy... I’m not wearing any panties under here.”
I gulp. “Uh, so?”
“So... if you’re chafing, that means to make it stop we’d have to go bare skin. That’s like... totally and completely wrong by anyone’s standards.”
“Well, yeah, but I swear I’d wouldn’t do anything intimate or inappropriate. Just a little bit on your butt, and nothing more... I promise. Please, Ella? Cross my heart and hope to die!”
Ella doesn’t answer me for the longest time, and I eventually conclude that I finally must’ve pushed her sensibilities too far – and that it’s only a matter of time before she forces me put my cock away for good or, even worse, does something to get me in huge trouble with our parents.
