Well, I don't know what sort of person would turn down an invitation like that, but that's certainly not me! I lick my lips a little then immediately pull down her pajama pants with my right hand, while my left pulls up her shirt in the same moment. No bra on our not-so-little heroine, and while she was wearing some blue panties I managed to push those down at the same time. Revealing...purple pubes? Interesting, if perhaps not so surprising. For her part Marcy squeals and covers her face with her hands.
"Tamara!"
"Just giving my roomie what she wants, isn't that right?" With her body now unwrapped and splayed across my lap, it's time to enjoy my little present, hehe. I grab a nice firm hold of one of her tits, and damn if they're not impressive. At least two cup sizes bigger than mine I'd wager, not that I actually know much about clothing sizes. I hardly wear the stuff if I don't have to, after all. The noise that comes out of her mouth while I do it's even more amusing, and I keep playing with her a bit to see what other squeaks she might make.
Meanwhile my right hand slips down between her thighs, and...oh Void, 'slips' turns out to be a more accurate word than I was expecting. I run a finger along her slit and damn near end up fingering her by accident, she's just that wet. Either I'm even hotter than I think I am - if that's even possible - or I can safely write off there being any sort of Embrace-resistance included in her regeneration powers. Since I'm already in there I go ahead and add a second finger, then push in a third. My fingertips can actually be pretty sharp if I hold them the right way, but let's just say I've got a lot of practice with using them in sensitive areas, yeah?
"Tamara! Oh my god!" One of her hands grips my shoulder while the other grabs on to the couch, and when I see that she's properly anchored I give her a grin and start fully fingerblasting her. Gotta admit, I don't think either of us were expecting things to move this quickly, but I am not a girl who likes to tap on the brakes. She offered herself up, and now it's a one way ticket to soaked-couch-town.
On second thought this couch looks brand fuckin' new. Stopping for a sec, I grab some of the paper towels we had with the popcorn and slide them into position. Cause yeah, if things are going where they look like they're going, Marcy here's gonna be unleashing a typhoon on this shit in a few minutes.
And damn if the next few minutes aren't even more fun than sucking off Impact. Like, that was good, don't get me wrong, but Marcy is just such an incredible play toy it's unbelievable. The noises, the eye rolling, the soft curves, the wetness...Void, I hope more humans are as fun as her.
Sure enough, just as I thought, in less than five minutes Marcy's lifting her hips and squirting up a storm. I catch most of it with my hand, sparing her pants and the couch, and rub some of it onto her belly before licking the rest off with my tongue. Her eyes grow wide as she watches me clean out the hard-to-get spots between my fingers, and it reminds me again that apparently humans have smaller tongues than I thought. I wriggle that tongue in her direction, and she finally finds her words again.
"Oh my god, Tamara, that was...it's never felt like that before! And Jesus, your tongue, I didn't notice...oh! But uh, I should do something for you now, right? I'd like to?"
I lean back on the couch while I enjoy the rest of her taste. "Oh? Been with a girl before, Marcy? Just curious."
She blushes. "Just boys, but uh...I was kind of thinking of...experimenting at college, you know? I was even thinking...god, it sounds so stupid now. But last night I started to get this fantasy of you and me, and how we'd get to know each other better, and then maybe after a couple of months maybe we'd go on a date..."
I can't help but laugh, and tease the bi-curious girl with a nipple squeeze. "Ha! Well, we shortcut that a bit, didn't we! Aha!" After my giggling dies down a more serious thought occurs to me.
In other cases maybe a reciprocal fingering or licking would be good enough for me. But right now, with my pouch all full of eggs ready to go? Yeah, there's no way I'm taking off my pants and keeping things contained down there. "Uh...so, I would like it if we could move on to something more...two-way, but there's something about me you gotta know first. Like, a mutate thing."
"Oh? Uh, I'm cool with whatever, or I can work around things, just, uh...so what's the thing to worry about, again?"
I motion for her to sit up and as she does I get to pulling off my own pants. As soon as I let my legs spread a bit, ovi comes out to say hello.
So, yeah. Basically my vagina isn't really a vagina - it can work like one, and pull in cum and all of that. But when the breeding urge gets strong it basically distends and flips inside out. In that mode, while it can function like a dick it hardly looks like one. Well, not a human one. If anything the shape is closer to that of an eight-inch horsecock, with that flared head, but the coloring and veins are more along the lines of a red rocket if you get my drift. It's got a kind of powerful look that I really kinda appreciate myself, but if I'm worried about any part of me putting off a human it's this. At least, one that's not fully Embraced yet anyhow.
As ovi gets to her full shape and size Marcy's jaw drops. "You've...you've got a penis, Tamara?"
"Sssssort of? It's...kind of excited and hard to get down when it's like this, but if it's too much for you..."
"No! I uh...I want to try. Does it, uh...work like a normal penis?"
I give her a grin. "Never used it with someone else before, actually. Want to try it and find out?"
"I'm your first!? Wow...I mean, I wouldn't have guessed. But yes! I want to!"
I give her an 'after you' gesture and she swings over to straddle my lap, leaving my ovi riding between her buttcheeks. She lifts herself up a bit to line things up...then blushes when she realizes she needs to rise a little bit higher still. "It's so big..."
"Just take what you can...we'll get there..."
Another of the differences between my ovi and a real cock is that it's a fair bit more flexible, after all, it's gotta stretch to accommodate a good flow of eggs and all that. Combined with how wet Marcy still is it's actually not that hard for her to fit the head inside. I can't help but shudder at the sensation of feeling trapped in her heat, and this time Marcy adjusts quicker than I do - even while I'm still twitching a bit, she's sinking further down onto me.
In the end she takes about five inches, which I bet we can beat once things get going, but it's a damn good start. "Alright...you feel so good, Marcy. I'm going to start fucking you now, okay?"
Now, normally you might expect the girl on top to be doing the fucking, but that's before you add enhanced strength to the calculation. I may not be at Impact level, but when Marcy gives me a nod it's not that hard for me to grab her hips and start driving her up and down. If you took away my tail she might be a bit heavier than me, but it's no problem at all to start bouncing her on my ovi, letting me get closer to her womb. And once that happens, hidden deep in there? Whoo boy, it's time to show off another neat ovi trick, baby!
After all, you can't just shoot a bunch of eggs through a normal cervix, or so I'm told. Instead some of the chemicals in my precum start working to soften things up a bit, make them stretchier...and once that gets going little tendrils start to come out of the tip to work things the rest of the way. I haven't actually done this before of course, but from the tremors that start running through Marcy's body I can tell that she's feeling the effects of her little baby room massage.
"Tamara! What's...it feels so weird! I mean...it's good, but...I've never felt it like that before!"
"Just close your eyes and let me do the work, babe. It's going to feel even better soon..." It's not a super-quick process, but Marcy sure isn't complaining about the few minutes it takes to get her ready, fucking her steadily while her womb gets more and more prepared to take a load of fertilized eggs. As her cervix starts to widen up enough to start pushing through, I can feel the first egg in my pouch start to line up, and -
WAIT.
I mentally come to a screeching halt, although fortunately Marcy doesn't seem to notice yet. I can't Embrace this girl! There's zero chance that I could hide it from Liberty Stars, that their newest healer is all mind-whammied and pregnant with alien eggs! And if I send her back home to Jef that's even worse! Sure, we should have privacy within our own rooms, but there's zero chance security doesn't know that Marcy was in the building - probably have her tracked up to our floor too. If she vanishes from her own apartment while I'm the only other one around, obviously I'm going to be the prime suspect! I can't get caught with my very first incubator!
Even if I get away, Mom will never let me hear the end of it!
What happens next is probably the hardest thing I've ever done. With a real, true supreme force of will I manage to mentally stop my eggs from leaving my pouch and sliding their way into my ovi. Marcy can tell now that something's up, probably because of how my face looks like I'm taking a shit, I'm guessing. "...Tamara? You alright?"
"Don't stop!" My voice comes out in a gasp. Maybe I can't breed this girl, but I'm sure as Void not going to let myself get edged like this, either. "Cumming soon!"
"Oh, okay! I'm on the pill so you can cum inside!"
A pill sure wouldn't stop a flood of Darkhive eggs, but the permission is enough to tip me over anyways. By carefully clenching in the right way I find out that I can stop my eggs from releasing while still having a proper, healthy cum. I don't have semen, obviously. Instead what comes out is a mix of lubricants and hormones, designed to help get the eggs into the womb and prepare the incubation process. Given that it's not all pouring into her womb as planned though it ends up being a pretty spectacular mess, and it's still pouring down my shaft when Marcy has her own climax a minute later.
She collapses onto my shoulder and we both spend a minute gasping, although Marcy probably doesn't realize just what part of that was such a workout for me. Of course, now that my head is a little more clear I do have some other concerns. Marcy just got...a lot more Darkhive chemicals in her than I was planning on. She's not fully Embraced, and she's not an incubator, so I shouldn't need to send her to the moon, but...what sort of effects is this going to have on her? I don't think we really planned for this sort of scenario.
Wait and find out, I suppose. I'll definitely be needing to keep a close eye on Marcy for a while though, and going by the look she's giving me I don't think she's going to be complaining about that.
"That was...so much better than any boyfriend I've ever had. My god, Tamara, you have just the most incredible mutations! I love it!"
She nuzzles up to me, and while my hands are running along her ass she whispers into my ear. "I think I'm going to really, really enjoy being your roommate..."
...This might have ended up making my privacy concerns even worse. Oops!
