Yes, you have

Your eyes moved up and down Stacy's chosen avatar. Much of her appearance bore some resemblance with the real life Stacy: Her straight brown hair with bangs, her big blue eyes (though Stacy wore unflattering nerdy glasses, her avatar seemed to have perfect vision). That's where the resemblance ended. Real life Stacy was nearly flat-chested, but her avatar had large breasts that seemed to be the same size as her face each. She wore a typical seira fuku style Japanese schoolgirl outfit that consisted of a blouse, a ribbon, a pleated skirt with a very short sleeve and socks. She didn't wear shoes.

Stacy moved close enough to touch your erection through your trousers. "For someone who isn't interested in me, you sure have gotten big down here", she smiled. "I am guessing I nailed my choice of avatar, amiright? Aren't you at least interested in finding out how perfectly the jiggle physics that we worked so hard on work in this world?", she asked and jumped up and down a few times, making the contents of her blouse oscillate.

"No Stacy, I'm still not interested", you said, "We are colleagues. It's not appropriate..."

"Technically, we are colleagues only in real world, and even that is going to change in a matter of hours. Our work is done here. Who's going to care one way or another", she tried to reason with you.

"No", you affirmed.

"Maybe if...", Stacy began and removed her blouse with surprising ease, revealing a white bra in similar style to her blouse, complete with a bow in front. Outlines of nipples poked through the fabric. "...you get to see them in a bra?", Stacy completed her sentence.

"No, Stacy, no, for the love of..."

She kneaded her bra-clad boobs in front of your face as if to showcase the jiggle physics model some more.

"You keep saying no, but your big cock is clearly saying yes", Stacy said, stroking your cock through your trousers.

"I for one am curious to see exactly how big we are talking here", she continued while unbuckling your belt and opening your fly. She reached into your pants and fished your cock out. It sprang out in its full glory. Your cock was as long and as thick as Stacy's forearm.

"Hah! My guess was right. You had some fun with the avatar customization options like I did", she said, pulling aside her bra to emphasize her words. A pair of perfect breasts bigger than Stacy's head fell out of the bra.

Without saying another word, Stacy shoved your cock inside her small looking mouth and sucked on it. She started to moan and stroked the base of your cock while giving you a blowjob. Waves of pleasure unlike you've ever experienced traveled through your body.

"Stacy, stop, we can't just...", you protested as she continued to blow you.

Stacy popped your cock out of her mouth but continued to stroke it. "Why?", she demanded.

"This is too embarrassing, we're colleagues...", you pleaded, breathing heavily.

Without letting go of your cock, Stacy sat down on the bed next to you. She put your head on her lap over her thighs and pushed her boobs over your face. "Well, why don't I bury your face in here. If you can't see me touching you, it can't be embarrassing, right?"

Stacy continued giving your a handjob while rubbing her boobs against your face. You felt Stacy's nipple against your mouth, and instinctively popped it in your mouth. Stacy started moaning.

"Ahh, that feels so good, keep on sucking. I might even...", Stacy began but you felt your cock starting to twitch as if to complete her sentence. Stacy lifted her breasts off you and you could see a ridiculous amount of cum spewing out of your cock, most of it landing on the bed and running down Stacy's hand, with some single droplets hitting her boobs.

"Oh wow, you let out a lot!", Stacy remarked in awe of your excessive cumshot.

You felt a strange mix of post-orgasm satisfaction and a lust for more of Stacy's perfect hentai body.

"I bet we aren't nearly done her", Stacy said as she pushed you on your back and climbed on top of you. As she lifted her skirt, you learned that she never hand any panties underneath, or they magically disappeared at some point. Stacy's vagina looked clean shaven, but given that this was her avatar, she probably doesn't need to shave anyway. Stacy climbed on top of you slightly shrunken, but still huge cock and made grinding motions against her labia and clit. Your cock started growing back to its full size again. You felt you head go crazy with lust for Stacy, watching her perfect boobs sway above you and her crotch grinding against yours. The motion of her breasts looked slightly unnatural, but mainly because they appeared way to perky and firm for their immense size.

"Please, Stacy, put it in", you begged.

"Ahhh, I though you'd never ask", she moaned as she slid your enormous cock inside her. It went in all they way until the base. Stacy bounced on top of you and you returned her pace by thrusting with your hips. Stacy's moans echoed through the simulated bedroom.

After a minute or so, you heard the familiar UI activation sound effect coming from Stacy's direction. She looked down at her crotch and moaned "Oh my God, Kent, you've got to check out X-Ray Mode! It's so fucking huge inside me, I can see you hitting my cervix!"

You quickly accessed your own UI and toggled on X-Ray Mode. Of course, it looked nothing like a real life X-Ray. Instead, you saw a perfect cross section of Stacy's vagina and womb and your enormous cock moving through them when you looked down. Your cock head was indeed piercing through Stacy's cervix at the end of each thrust.

"Oh my God, it looks so lewd, I think I'm gonna...", Stacy managed before you watched the folds of her vagina starting to convulse around your cock in your X-Ray vision, and clear liquid shooting out around your cock. You responded to Stacy's orgasm by cumming a few seconds later. You watched cum pump out of your cock and fill Stacy's womb until it expanded slightly, finally oozing out in copious amount.

"That... was pretty amazing... for someone... not interested in me", Stacy panted as she climbed off of you, trying to collect her breath.
