the first date

The next day at school , Mark and Sophia accidently bumped to each other, still felt embarrassed of what happened, they didnt exchange anything. Other than that, the whole day was uneventful. Mary is leaving in 4 days so if Mark wants to enjoy his aunt body, he's not gonna have alot of time left. But there's sometime more important in his mind, about upgrading the device. Precisely, he need to shorten the time of sitting in the chairs, transferring the minds back and fourth to an even shorter time. With that, he drew a blueprint that resemble a VR headser, and a USB port to store the mind offline, and it should take as much as 30s to complete the process, shorten the time dramatically. Combine with a program on PC that allow the mind in the USBs to be streamed, basically make a digital 2D real time version of themselve on the computer. Mark immediately jump into work and finish it almost two days without rest. Its about 9pm midnight, and Mark has not gotten even a rest, his body is fully exhausted. But he finally finish with the upgrade. A pair of headset, 3 upgraded USB and a program that can stream user's brain

Yet again, he need someone to test his new products on. But like it or not, he have to use Aunt Mary again as a Guinea Pig. Mary on the other room, has been worried for Mark the last 2 days. He barely gotten sleep, or even eat, and just staying in the room doing what god- know works. When Mark called for her to enter his room, Mary was shock to see her niece fully exhausted, but left his final energy as excitement of the complete products.

"Uhh..uh. aunt Mary, i need you to try this out for me"

"Another inventions of your huh? .... is it gonna hurt when i try ?"

"absolutely not"

"uhmm..... okay!"

She came near his bed pick up what seems to like a VR headset, and place it on her head

"It only take a bit of time, are you ready ?"

"yes, but how fast is......" she fell **** after 5 second

After 30 second, Mary mind is completely drained, leaving her body in a state of braindead, not lifeless like before. the upgrade version, or PROJECT BETA, make sure that all body organs are still in working, only the brain's thought, emotion and thinking are drained from the body, into the USB

Mark, observing the quick process, while realizing that his body is giving up, and he must transfer to Mary body in order to keep working. He immediately take out the USB, put the headset on his head, connecting wirelessly to the one that already on Mary head. In just a little of 30s, Mark has already wake up in Mary's body again, this time feeling no sign of tiredness. Then he connect the USB to the pc, streaming his aunt's brain

"Wow, you can actually digitalize me" Mary voice came from the computer

"Yes, how are you feeling in there" Mary voice outside asked

"i feel... nothing. I can only think and talk and thats it"

"But, its kinda weird that you are using my body out there. Its like im talking to myself, literally" Mary continue

"Yeah, but using your body, i actually feel more rểashing"

"That because you barely sleep the last 2 days"

Both Mary shared a laugh

"So.... are you keep me here and stealing my life forever ?" Digital Mary ask in a funny way

"Uh Uhmm, no...... i actually want to play with your body in a little bit, it been while since the last time im inside you"

"So matsurbate or what "

"Wha..."

"its fine, if i could even stop you anyway"

"So.... thank you"

Mary immediate undress, revealing her boobs and ass to the computer

"Hey, i looked in a mirror before but at this view, i just realized how nice of an ass i have" said Mary

"You really a little bit perverted are you ?"

"okay, maybe a little bit" Mary said as if shes not trying to deny it

Mary then give her round butt a light slap, then start going up to grope her medium size boobs with hardened tits, with her other hand start fingering the pussy. Meanwhile, to outside Mary, it just like shes streaming herself fingering her pussy to the world, just the thoughts make borrowed body gone hot like wild fire and shes start moaning . To the Mary on the screen, seeing herself masturbating in third person view as awaken new feelings inside her, she doesnt know what the feeling is but its mostly horny and excitement as the woman in front of her started to put some fingers inside her pussy, while moaning loadly and furiously grooping her boob. "IM CUMMINGGG" as Mary let out a big moan and squirt all over the flour, while real Mary on the screen witnessed everything, and unable to do anything. But Mary doesnt feel hopeless or disgusted, but rather amusing and horny

"Happy now, ma'am ? " Mary ask while Mary enjoy the afterglow

"Its felt really good"

"So, can i have my turn to have my body now "

"Uhm.. i dont really know, i want ano....."

"okay, so you wanna keep my body tonight ? Be my guest"

"But i havent sa...."

"Thats fine, you could keep using it if you want"

"But i have to ask, why do you want me to use your body so much ?"

"Well, uhm, i have to admit, while you're using my body, and my brain is off. I feel like i can get some good rest after a long time" Mary explained

"And im kinda lazy and bored, so most of the time i just go to sleep without having my body to do anything, so when youre using my body, its like i got to workout but not actually do anything. Two bird one stone, i got rest even better, while youre doing my job for me"

"Damn you" Mary said in disappointment

"So anyway, goodnight to me, and ill see you tomorrow, also remember to keep my body clean and nice"

"hm.... im sure i will"

Then Mary on the computer turn herself off, leaving Mary outside to wonder how easily she can trade and share her body, her life

As the night gone and the day came, Mary and Mark have returned to their original body and life. Mark also successfully invite Sophia to his house to have a look at his new invention. At the house, she is again greeted by Mary who also join them upstair to the machine. Sophia, after understand what this device is all about, also decide to try it herself but unsure she want to into whose body. Mary immediately offer her body, and suggest that Mark could use Sophia's body. Both **** at first, but then accept the offer because there's no better option. But Mary also ask Mark not to stream her brain because shes want them to have private time together

Mary is again gave up her body to let Sophia in, with Mark also hop in to Sophia body. Waking up, Mark, or new Sophia have no difficulty get used to the new body, but Sophia have a hard time get used to her shorter, petitier body as she waking up

"hey are you okay" Mark in Sophia voice

"Im fine, but, seeing myself ask me if im okay, is kinda weird dont you think "

" yeah, i can relate"

The new Sophia and Mary start looking at their new body, admiring all the curves and the beauties on their bodies. Mark couldnt help but start touching Sophia's body, starting with the boobs. Mary stared at her old self as if she wanted to tell her to stop, but also couldnt help herself and become more and more horny when looking at her new boobs, sooner or later shes start exploring the new body

"Uhmm, i think we should go to a more private place" Mark in Sophia voice

"yeh..... i was thinking the same"

Then both women head to Sophia room, ready to explore every part in their new bodies
