Accept having sex with Meilyn.

"Yes!" I say almost immediately. "Yes, I want to!"

"Then what are you waiting for?!" Meilyn asks 2 tones higher than usual. She is clearly trying to keep her cool, but I can see as clear as day that she is as agitated as I am, if not even more. "Go for it and stop making me wait!"

The girl immediately sits on the sofa and spreads her well-toned legs while facing me, offering me the first clear view of her plump pussy, beautiful and bulky, with thin pink-colored lips departing from the middle and forming a little gap near the bottom.

If my switch was already flipped, now it's been turned inside out. The impulse coming from my groin becomes almost ferocious, and I feel the sudden urge of throwing myself over this woman and skewer her with my massive cock. I don't know if this is due to the influence of Devon's hormones, but I'm having a really hard time controlling myself.
And I gotta control myself. I have to. Since despite my absolute lack of experience, I've got the inkling that this black monster between my legs won't enter that little pussy without a fight, regardless of how wet it is.

And Meilyn seems to think the same thing, because the moment I get closer and she can get a new perspective of my huge dick and plump balls against her little hole, Meilyn's façade immediately cracks, and her confident face turns into one of apprehension. It looks like she finally understands the true 'dimension' of the challenge she has set upon herself.

However, she is still smiling when she turns up to look at me in the eyes.

"Come on... what are you waiting for?"

"A-Are you... gulp... are you sure about this?" I ask with my last bits of self-restraint, already grabbing my manhood with a trembling hand.

"Didn't you hear me when I said that I'll do whatever it takes to be your girlfriend? And what a pathetic girlfriend would I be if I couldn't even take on my boy's cock, don't you agree?"

"Haahhh... haaahhh..." I have no more words to say, so I push my hand forward, making my eager dick descend like the arm of a crane, until the girthy mushroom head is directly facing Meilyn's hole; so huge in size that, the moment they both enter in contact with each other, her pussy almost entirely disappears under my bulk.

"Aah..." I moan.

"...fuck..." She says with a worried smile.

Then, I start pushing forward, and I immediately feel a shift on Meilyn's flesh. Aided by her own fluids already acting as a lube, the meaty lips of her pussy start parting both ways. For a moment there I panic when I see my cock descending way too much, thinking that I've missed the target. However, I haven't really missed it. Somehow, my dark rod manages to anchor itself in place, and immediately after I get rewarded by the feeling of an opening appearing right there and expanding outwards, slowly engulfing my meat with its own.

"Huuuunnnnnnnghhh...." Meilyn moans quietly while biting her lower lip.

Watching the thick end of Devon's massive dick vanishing through a hole that seemed too small to even attempt to contain it might be the most fascinating thing I've ever witnessed in my whole life. And the feeling is unbelievable. A paradise of moist springy meat, hot as 9 hells, all enveloping the most sensitive part of my borrowed body. I can't help but whimper like a kid while slowly projecting my hips forward.

"IIiiuuuunngh! Aah! D-Dev-I mean, M-Mark! Wait! ...haahhh... wait a moment, let me breathe!" Meilyn pleads with her eyes closed while gasping through her open mouth. "You're so thick... Oh god, I didn't expect it to be this thick..."

"A-Are you okay?!" I ask, worried about her.

"Y-Yes! Yes, haahhh... I am... okay." Meilyn pauses for a moment, trying to level her breathing. "H-How much is... how much is in?"

"The tip is in!" I exclaim, excited at how the pink glans has completely disappeared within Meilyn's gaping hole.

The girl carefully leans forward, staring at the point where our sexes join together with the care and hesitation of someone looking at the rattlesnake who snuck into their basement. Then, she lets herself fall back, chuckling with a forearm covering her pretty face.

"Gory hell, now I'm kinda proud of myself!" She laughs between gasps. "I wasn't sure if that monster would even fit inside-EEck!" She suddenly yelps the moment I push myself into her even further. "You big dummy! I-guUUuhh! I wasn't ready!"

"I'm sorry!" I loudly apologize. "I can't resist, I... I think I'm about to cum!"

"What?! Already?!"

"I'm sorry!" I repeat in a **** tone. "I've been keeping it for so long that I just...! Aah! I c-can't-!"

Indeed, I've been bearing with this erection for way too long by now. So far, I've been keeping my urges back, but at the end I still am just an inexperienced virgin with a tool way too large and overbearing to properly control. Devon's libido it at its boiling point, and it has already gone way beyond my control.
The only thing I can do about the inminent release is to choose at which direction I aim it.

However, Meilyn ends up choosing for me.

"Alright, screw it!" She exclaims with an unexpected eagerness while she takes out her shirt and bra in one quick movement. "Give it to me! Cover me up with your cum!"

I pause for a milisecond to admire the naked beauty under me. But as the orgasm explodes within my crotch, I gasp and pull out my engorged manhood from her pussy, so quick it makes a loud *squelch*
Then, immediately after, I'm letting out a wordless growl with my black cannon pointed towards Meilyn's belly, and not even a second has passed before I start spurting jet after jet of the thickest white goo all over the woman's naked torso, staining her beautiful frame with the bountiful product from Devon's large balls.

My new gonads keep on giving for what it seems like an enternity. And when the orgasm finally settles down, Meilyn's belly almost looks like a piece of bread covered in consensed milk.

"..haahh..... haahhh..."

"Uff... haahhh... ffuuhhh..."

Oddly enough, the woman's breathing seems even more agitated than my own, even though I was the one cumming. Meilyn is staring at the vast ammount of warm male spunk covering her pale skin with an expression that seems almost intimidated, as if she is thinking something like 'what would've happened if all of this went inside of me?'

After visibly swallowing saliva, Meilyn looks at me for a long moment. But then she breaks her silence with a nervous but excited laugh.

"Gosh, Mark, you're such a gentleman. You didn't need to hold back for me, you know?"

I stare at her in confusion. But then I realize she was being ironic.

"S-Sorry..." I say, sheepishly.

Meilyn surprises me with a bright lighthearted laugh.

"How many times do I have to tell you to stop apologizing? You big dummie."

"I... I feel like this is one of those things I should be apologizing for." I say, scratching my raspy hair. "...uhm..... Meilyn?"

"Hmmm?" She asks while carefully picking up a droplet of my cum and putting it into her mouth.

I look at her, dumbfounded by what she just did. And for a moment, I forget what I was about to ask her.

"What?" She insists, apparently oblivious of my reaction to her casually deciding to taste Devon's cum.

"Uhm... Can I..." I awkwardly grasp my still throbbing black cock. "...Can I put it back in?"

Meilyn opens her eyes wide and looks down, noticing how Devon's manhood still looks about the same, barely losing any of its hardness from before.

"...shit... I should've known." She says with a nervous laugh. But then, she looks into my eyes while obediently spreading her gorgeous legs. "J-Just try to be gentle, will you?"

No need to say anymore.
I immediately lower my new body, aligning my host's large dick against Meilyn's gaping hole, and push forward in one decisive thrust.
Be it because the recent orgasm might've taken away a tiny fraction of the previous rock-hard stiffness, or be it thanks to Meilyn's vagina beginning to adapt its shape to match my size, this second time I manage to slam the entire upper half of my massive dick inside of her, making it disappear between the girl's overstretched lower lips.

"Ouuugh!" I grunt.

"AHEEeeehhh!!" She yelps, and starts shaking immediately after.

It's like her whole body is turning into mush. And all it took was one simple thrust.

For the first time, I don't need to hold my dick in place with a hand to prevent it from slipping away. So I let go of it, grab Meilyn by the ankles and start a careful, slow push, moving my hips back and forth.
Meilyn's gasps and little yelps are now evolving, becoming louder, until it gets to a point where the girl is straight up moaning like a regular scene from the hundreds of porn movies I've watched but never got to experience.

For the first time in my life, I'm fucking a woman. This... This is what sex is like.

I smile, ecstatic.

I think I'm gonna become addicted to this.
