Chapter 2
"You aren't ready for it, I guarantee you…" Vi said, lying on the outdoor couch directly underneath Yara, who was poised with her absolutely delicious ass in the air, ready for what I had to give her.
"I am…" Yara said, reaching down to cup herself, her fingers spreading her lips, preparing herself.
"Big words for a girl who has no clue, aren't they?" I placed the head of the dildo at Yara's entrance, grabbing her round ass with absolute glee.
"Then I guess you better fuck me so hard you prove me wrong.
" Yara pushed back into the dildo, enveloping the head with her gorgeously pink pussy.
She let out a content groan and leaned forward, kissing Vi deeply as I pressed the length into her.
Vi's hands instinctively reached up and cupped Yara's tits, holding them gently and pinching the nipples.
I fucked her with the strap-on, watching it go into her beautifully, the toy pleasing her in ways that were incredibly clear.
"God…Emma…Vi wasn't joking." Yara gasped. "This thing…"
"Yeah?" I said. I slapped Yara's ass a little, nothing more than a love tap. "Tell me how good it feels in your pussy, Yara."
"Fuuuck…" Yara groaned, pressing herself back into me, making the toy go further in.
"Speak up or I'll stop…" I said. I gripped Yara's shoulder and drove into her harder, showing her that me stopping was the worst possible option.
"Oh…fuck…this feels amazing…" Yara sighed. "You're fucking me with this goddamn toy so hard and good…God…you're…a fucking sex queen." Yara moaned as I grabbed her waist, and I looked at Vi.
Yes, sex was amazing, obviously, and I loved this open and loving group that I'd somehow gotten into, but, the look on Vi's face was better for me than any sex I could imagine.
That look, a content and blissful smile, her beautiful pink hair scattered in a hundred directions, the redness on her cheeks as her body dealt with the intensity of what was happening around her, that was what I did all of this for.
"I love you, baby…" I said, my eyes locked with Vi.
"Which one of us?" Yara said, her voice languid and strained.
"Both, absolutely both." I said, recommitting to devoting my attention to Yara.
I slapped her ass, and she reached around, pulling my hips into hers.
"You're making it so fucking hard to not come, Emma." Yara moaned.
"Want me to switch to Vi for a bit, let you cool off?" I said.
Yara nodded and leaned forward, pulling herself off of me. Vi was right below her, so getting into position only required me to change my angle. I slid myself into Vi, gripping Yara's ass as I did, holding her lips open with my thumb.
"Fuck…yess…" Vi moaned as I entered her. She was the first person other than myself to test this new strap-on, and she very quickly became its number one fan.
"You love the way that feels inside you, don't you?" Yara said.
"Yeah…I love…how fucking good this thing feels, like…the way it just hits all my sweet spots…"
"I think you have a lot of sweet spots, girl…" Yara laughed at Vi and playfully bit at her neck, then tangled her fingers through Vi's hair.
"And you two know them all." Vi laid back and took my fucking for a while. "Mmm…what flavor of cum do you have in it this time, Em?"
"I only have the raspberry ready right now." I said.
"But you're telling me I could eat raspberry-flavored fake cum out of Yara if you switched to her and fucked her brains out?" Vi said.
"I suppose that's what would happen." I said.
"You know I want that, Em…"
"That I do." I chuckled a little and shifted to put the dildo back into Yara, pulling her hips toward me to drive the whole length back into her waiting hole.
"Ohhhh, fuck!" Yara groaned, her head dropping onto Vi's shoulder, and Vi reached up, slipping two fingers into Yara, adding to what was already so obviously a magnificent sensation for her.
"Do it baby…come for me and Emma…I know how good that feels in you…" Vi clasped her arm around Yara's back, dragging her nails along her dark skin.
"Oh…shit…that's so…fucking good."
Yara arched her back, and I felt the small pump inside of the strap-on harness flex and whir a little. I needed to do something about that goddamn sound…later.
"Oh my god…holy fuck…" Yara gasped, the fake cum flooding her, filling every possible gap of space.
As a somewhat latent pansexual, I always loved the feeling and intensity of cum filling me, but since I've been more devoted to women lately and all of the trans women who I'd been able to hook up with had gotten into frustratingly monogamous relationships, I had to turn my engineering skills to replicating real cum as much as possible.
What was going into Yara right now was Version 3. 3b, and the best simulation yet.
Of course, to most people that precision engineering of the viscosity, miscibility, and flow of this simulated cum didn't matter as much as how it looked seeping out around a soaking-wet dildo, but…to me, both parts got me off if I was being honest.
"Fucking hell…" Yara groaned, the last bits of the reserve pumping into her. The cartridge system was the way to go, much better than the unstable rubber bladders or PVC tubing…
Hey, Emma, you're currently fucking the hell out of your gorgeous friend, geek out later.
"Told you it was amazing…" Vi said, triumphant and proud of my engineering skills.
"I have…never fucking felt that before…" Yara leaned forward, pulling off the dildo, and I noted that the fake cum clung to her in the exact correct way.
"Oh my god…I forgot you've never been with a guy…"
"And I don't have a fucking reason to, but that…I'll want that later…" Yara groaned and reached back, massaging her pummeled ass. I watched as the viscous substance trickled out of her and onto her thighs. Again, damn, I was good at making this stuff.
"And I want to taste it, right now…" Vi said, eager and already moving out from under Yara so she could eat her out.
"Never thought I'd see Vi the cumslut…" Yara laughed, shifting and rolling onto her back.
"Oh, you're about to…" I laughed, knowing how feral my girlfriend went for this stuff.
Vi was between Yara's legs before Yara could say another word, and Vi had a mouth full of simulated cum a few seconds later. Vi groaned and moaned, looking up at me and winking, then returned to devouring Yara, who had her legs around Vi's shoulders.
"Oh my god…girl…you're eating me like that stuff is fucking ice cream…" Yara pressed her hand against Vi's head, seeming to not be sure whether to push her harder or make my wild girlfriend back off.
"I mean…it's not far from it…" I spare Yara the finer details of lipid structure and the use of a lactose-like disaccharide to mimic cellulose, and I'll spare you as well… "You should taste it." I smirk.
"Mmm…guess I have to…can I taste some of Emma's fake wondercum, Vi?" Yara said, a huge grin spreading across her face.
Vi took a deep lick into Yara, something that was almost sexy enough to get me off on sight alone, and she then crawled up Yara's body, a shimmering pool of my substance cupped in her tongue.
She nestled into kissing her, passing it into Yara's mouth.
I had a massive moment of pride as I watched Yara's eyes light up at the taste of it.
"OK…damn…Emma is approaching evil genius territory…she's made a lesbian love the taste of cum…"
"The real stuff's not…nearly as delicious, but it has its appeals." I said. I unhooked the harness from my hips, feeling a small pressure point from the edge of the cum cartridge on my hip as I pulled it away. Damn, another prototype needed.
"Emma, get your genius pussy over here so I can get you off…I'm not going to let someone as good as you go without an amazing orgasm for all of this."
I didn't need to tell Yara that I had already very much had three orgasms just in all of the efforts from tonight, but I definitely could stand a fourth.
I moved over to the couch and Yara's fingers guided themselves into me with shocking ease.
Yara and Vi were still making out, Vi taking the remnants of the fake cum out of Yara and bringing them up to Yara's mouth on sticky fingers that she greedily sucked, and the image of this was enough to send me over the edge in almost no time.
"Fuck…" I said, coming hard onto Yara's hand. I wasn't super loud when I came, but something about this one made me really let loose, and I was fairly sure my moans were going to wake the neighbors. Fuck it, hearing a hot woman orgasm was probably the best alarm ever, right?
"Damn…that has to be a record." Yara said at the lightning-fast orgasm she coaxed out of me.
"I'm fully willing to try to break that record any time you want to, Yara…"
