Stepbrother Under Wraps(12)
Shit – I hadn’t even thought about what would happen if she told on me! In fact, this could all just be some elaborate way to get back at me for insulting her earlier!
But then, Ella takes a deep breath in... and lets out a long sigh.
“Fine,” she says in a barely audible whisper. “You can rub it a bit on my butt, but only for a few seconds, and you have to stop the instant I say so. And don’t you even think of putting it anywhere else.”
Ella moves under the blanket, and I feel her hips lift off the cushion as she slides the back of her tight leggings partway down her thighs. When she returns her butt to the cushion and snuggles close, my virgin cock makes contact with another person’s bare skin for the very first time in my life.
Warm, soft, smooth, feminine skin. And this time it’s not a daydream!
“Holy shit,” I breathe in absolute awe. Angling my body against Ella’s, I carefully pull my hips back... and, when I push forwards, the bulbous head of my cock parts the supple flesh of her buttocks, and slips into the hot, tight groove between.
Whoa – this is so amazing! I can’t believe this is actually happening!
“Geez, bro,” mutters Ella. “I didn’t mean you could put it in there! But whatever floats your boat, I suppose...”
My sister’s ass crack is hot, and soft, and tight, and surprisingly moist. I push my hips forwards as far as I can, sliding the full length of my cock between her chubby cheeks until my glans poke out the top and into the sting of relatively cold air.
“Mmm,” mumbles Ella, “have to admit that feels kinda interesting. Just how big are you?”
Way bigger than all my friends, I reply inside my head. I’m proud enough of my size that I have it measured down to the sixteenth of an inch – but it seems silly to brag to Ella, especially since she can’t see anything anyways. “I have no idea,” I whisper in a husky tone.
“Yeah, like I believe that.”
I begin making steady hunches back and forth, desperately holding back the urge to moan aloud as incredible bursts of sexual ecstasy fire from every part of my cock – and not just from the outer rim of the glans, like I’m used to during manual masturbation. Now, I’m receiving the most exquisitely pleasurable sensations from the underside, too, which is usually too sensitive for me to even touch... and all along the shaft from the friction and compression of her cheeks, and even from the pressure of the smooth back of her groove rubbing against the bulge of my urethral tube.
My pelvic muscles are convulsing almost constantly and precum is leaking in a steady stream to lubricate my way, so I switch to taking longer and more forceful strokes, trying to simultaneously contact as much of Ella’s flesh with my cock as possible. I soon notice that there’s something near the beginning of my stroke that the head of my cock keeps catching on, something along the back of the groove that’s both a slight depression, and burning hot in temperature. When I pause on it for a moment and actually feel the knot clench, with a sudden rush of blood to my head I wonder if that’s Ella’s asshole.
Am I actually rubbing my cock back and forth over my sister’s asshole? I can’t see anything and have no real idea what I’m touching, although It’s logical it would be somewhere back here... but Ella hasn’t said anything about me doing that, and it does seem like something she’d complain about.
My rambling musings are interrupted by the sound of Ella’s whispers. “So, Tommy... is it working? Is it going down yet?”
“Um, not really,” I murmur in reply. Frankly, I’ve never been harder in my entire life!
“Yeah, thought so. Did you want to see if another angle works better?”
What other angle could there be that wouldn’t immediately alert mom and dad? “Uh, sure... if you think it’ll help.”
Leaning away from me, Ella fumbles under the blanket to pulls her tights all the way down to just past her knees. “You take ’em off too,” she whispers, picking at the waistband of my sweatpants with a fingernail. Although I’m not sure what she’s getting at, getting even more naked under the blanket seems like a fantastic idea, so I follow suit and slide my sweatpants and underwear all the way off my butt, and a good distance down my legs.
Sliding her body a little to the left, my sister lifts her right leg slightly, presses her bare ass hard against my abdomen, and then lowers her leg – handily sandwiching my long cock between her thighs. Wiggling her body back down until the backs of her thighs meet the fronts of mine in a true spooning position, my cock is forced to bend backwards between her legs... until she releases the pressure, and it suddenly snaps upwards and wedges itself into a wall of flesh that’s incredibly soft, burning hot, and detectably wet.
