Jen from QA, accidentally helping you test some features

I recognize that sultry voice and turn my head to see a tall, sexy succubus walking through the closed door. She is breathtakingly gorgeous and her nude body is amazing. Huge breasts, supernaturally round and perky, bounce with the perfect jiggle every step. Her curvy hourglass shape narrows slightly around her waist before flaring out to wide hips and what could be described as a firm juicy ass. Her glistening pussy is dripping above her long toned legs.

All of this is accentuated by her grey skin with distracting and seemingly shifting patterns of tattoos all over her body. She has deep red eyes, red lips, and long red hair fanned out like it's being blown about by a light breeze. To top it off she has glossy black horns and matching long fingernails/claws. She looks at both of us and licks her lips with her very long tongue.

Kathryn is staring unmoving with her mouth open. "Oh dear, I think I broke her. This usually does the trick." She didn't so much walk as sensuously strut towards my frozen friend to stand right in front of her. Kathryn's eyes widen as she has to look up slightly to stare at the enormous breasts, each noticeably bigger than her head.

The succubus carefully unzips the onesie and helps it off her shoulders. The big garment pools to the floor around her ankles leaving Kathryn naked and exposed. The succubus leans over the small woman and runs her fingers across her cheek, down her neck, across her chest with a gently squeeze of a breast, down her stomach, and settling over her glistening pussy.

Kathryn started trembling at the first touch and by the time the succubus reaches her pussy she is shaking violently. The tall lusty demon leans down to whisper in her ear, "This will make it allllllll better." She licks Kathryn's neck with her long tongue as the hand at her pussy flexes.

Kathryn stiffens up with a long scream of pleasure until her lungs give out. A few long moments of silence and she collapses, gasping for breath. The succubus easily catches her, the small woman looks tiny compared to the big buxom lust demon. She carefully deposits the naked young woman onto the bed next to me. Kathryn flails about before grabbing me tightly. She is curled up and still moaning in pleasure.

"Wow, she is incredibly responsive and amazingly aroused. Your Captain here is so much fun! We love what you've down so far and where you seem to be heading. You two made excellent choices and she is delectable!" The long tongue licks her deep red lips again. "Mmm, I wouldn't mind tasting her more."

As the shaking subsides Kathryn finally seems able to speak, "You're the hottest, sexiest person I've ever seen! And I really, really, really want to play with you!"

I take this as an invitation to untangle Kathryn from me and give her a nudge to sit up toward the succubus who has taken a seat on the bed next to her feet. I pick up my phone again, go to her HotKeys tab in the CG app and hold down Rub Breasts. Kathryn's hands lunge forward and start kneading the huge orbs in front of her, making their owner gasp. The Magic Hands feature seems to work as intended, as a blush starts to rise from the succubus's grey breasts and creeps up her neck towards her face.

"Ohhhhhh yes, this is even better than when we tested that feature internally!" The succubus lays back across the foot end of the bed and pulls Kathryn on top of her, while I take my finger off Rub Breasts and press Bend Over and then Lick Nipples. Kathryn makes no effort to resist the app's influence, nor to hide her enjoyment.

"By the way (ohh), I'm Jen." The succubus has trouble speaking between pants and moans. "I'm a QA tester for the (ahhh) Custom Girls! app, and that involves (mmmh) gathering feedback about the (hhhhaah) customer experience. I take it you're (ohhhh) thoroughly satisfied?"

I take my fingers off Kathryn's HotKeys, letting her continue on her own, and lean over towards Jen myself. "Well, I wouldn't say no if you're willing to help me out here yourself..." I grin at her.

"If you insist (ooohh yes) - but I think you have to get off the bed (mmm) so I can get to you."

I get up and position myself at the foot end of the bed next to Jen, while she scooches back a bit to hang her head over the edge upside down. Her hands pinned down by Kathryn, she just seems to concentrate on my crotch, and suddenly my boxers slip down my legs all by themselves. I kneel to give her better access, and Jen wastes no time in taking my hard tip into her soft mouth, kissing and licking around it. Her moans make it all the more pleasurable, and Kathryn is working hard on bringing her closer to climax.

After a short while, she reaches that climax, bottoming out on my cock and breaking through my remaining resistance. I feel like I'm in heaven as quick bursts of seed flow out of me and down her accepting throat, managing to not even spill a drop - probably through some quirk of her succubus anatomy.

Dazed, I sit down on the bed again, while Jen proceeds to right herself and gently rolls Kathryn off of her. "I'm so happy I insisted on coming back for more feedback, because having fun with you there was great! I could play with both of you for days!" Kathryn lets out in involuntary moan and shiver at that thought. "Maybe later when I'm not on the clock."

"We love what you're both doing and want you to keep at it! You're leaving huge amounts of arousal in your wake. The burger joint was brilliant! Keep doing things like that and you will make me a very... happy... succubus." She ends by emphasizing the last words with an even more sultry/sexy voice while leaning over to me.

Jen suddenly stands up again, her huge breasts bouncing and jiggling. "Oh, and one last thing. You unlocked a Mystery Bonus for your girl when you hit Level 2 with her. You might want to check that one out, because it's sweeeeeet!" She giggles and winks at us. "Anyway, I gotta go now, got some new features to test!"

"Wait!" Kathryn interrupts her. "You can't just leave us without getting me off first!"

"Of course I can, darling. But tell you what, James here will surely oblige you." She grins and waves a hand at me, and in an instant my dick comes back to life. "You won't always have me to do that for you, but I think there are purchases in the app so that your girls can do it for you. Anywho, have a sexy day you two! Byeeeee!" And with that, she walks out the closed door as abruptly as she came in.

Kathryn stares at me, then down at my crotch, then back at my face again. "Do you... want to do this?"

I look at my phone, which lies discarded on the bed, half covered by a pillow. "First I want to take a look what that Mystery Bonus thing is. Jen kinda hyped it up quite a bit."

Switching through the tabs, I find an additional one at the end, just labeled Mystery. It has a rather short list of purchasable perks.

Choose wisely, for you can only choose one!

Mystery Touch - FREE

Mystery Kiss - FREE

Mystery Voice - FREE

The buttons for the three options also glitter slightly with purple sparkles. The UI designers have really gone all out on this choice.

"So Kathryn, which one do we pick?"

She ponders for a moment. "I don't know if I want the Touch one, I already have that Magic Hands thing and it works really well. The Voice one seems really intriguing though. What do you think that does?"

"I don't know, with the way this app works I guess it makes people aroused at the sound of your voice? Sounds a bit impractical if you just want to hold a normal conversation."

"What if it's a control thing that makes people obey me?"

"Do you want that?"

She pauses. "I don't know what I want. None of these options explain anything!"

"So which one do I buy for you?"
