Mary let Mark use her body when ever he wants

"Ahh....What's time is it" Mary yawning as she waking up

"Ohh......Aunt Mary..... U wake up ?" Mark replied

"I feel kinda..... Refreashing ? What have you done while i was sleeping huh, young man ?"

"oh, nothing much, but i can i tell you this, this is pretty not safe for work"

"oh dont worry, ill be listening"

Mark told Mary about the ability of the machine to transfer consciousness to empty body, basically told her that he was possessing while she was sleeping, or rather being save as a digital file on his computer

Mary was shocked but also exciting, she told Mark to keep going. Continuing the flashback, he used her body to try out some new cosplay stuffs and accidently bump into an old friend, who also happen to be his crush, offered to go cosplay with her in about 2 days, an offer which he cannot refuse.

Mary at this point has understood most of the flashback. She thought for a second

"Mark, i dont have anything about you borrow my body while i was basically sleeping, but you know....uhm"

Mary blushed as she continuing, Mark kept listening but he had already prepared for the worst

"y'know.....do you.......... having sexual acts in my body."

Mark was speechless for a seconds, but was completely aware that lying right now would be futile

"yes, i did,..................i was masturbating in your body"

Silence filled the room as neither of them know what to say

After what seems like forever. Mary exclaimed :" You know, i understand that boys your age have some pretty weird thoughts about women body and sex as a whole..... I actually still a virgin and never had sex before, so i usually masturbate alot....but i gave up just recently" she kept blushing hard

"So if you want to borrow my body to try out some new experiences, just let me know. And please, i want to save my first time to my husband, so if you can do please try not to have sex in my body" Mary still blushed hard as she request

"I promise..... i will only borrow your body for a cosplay, after that, ill never touch it again"

"nah dont worry, ill let you use me anytime you want, you just need to let me know" Mary giggle quitely

"hmm

also, Mark ?"

"hmm yes, Aunt Mary"

"If you could,..... if you could borrow your female friends bodies.... can u.....hmmm. share it with me ? i always wanted to feel a young body for so long"

"What ?" Mark is completely speechless

But thinking about the potential this project has, the amount of women bodies he could experience, Mark become more and more excited about the idea of being able to borrow female bodies and use it to do whatever he wants

"Of course, you and me can both become women and having fun together" Mark told his Aunt confidently

From that day, Mary has become Mark partner in crime. That night, Mark can observed that Mary experience pain in the crotch area, probably from the excessive masturbating in a long time, after all he cummed 3 times in her body

The next day, Mark went to school as usual, Mary stay at home to prepare lunch and dinner. At the evening, Mark asked to use her body again to try some outfit. Mary **** at first but then accepted to sit in the chair and wear the headphone, but not without condition

"Please dont masturbate excessively in my body tonight, it was painful when i sleep last night"

"Dont worry, i only do it 2 times per day" Mark said jokingly

"Such a bad boy" Mary Pouted

The transfering sequence started, it went much faster than the first time, only lasted about 3 minute. After 3 minute, Mary is now just a lifeless body on the chair and a file on his computer that contain her memories, thoughts and emotions. Mike then transfer his mind into her body, took around 2 more minutes

"Tonight is gonna be fun, Aunt Mary" Mark said as she woke up

Without wasting time, Mark stripped her Aunt completely nude to again admire the body while her horniness slowly building up. She took out the student uniform to again wowed as how the outfit was basically perfect in her body. A short milf. with a skirt that reveal most of her thighs, also part of her round ass, the black bra and white shirt that tightened her boobs to reveal her d-cup size melons. Her twin ponytail that tied her hair along side her shoulder making her a real life copy of her anime waifu. She couldnt help but masturbate again as her Horni- meter has reached max level. She let out loud moans as she brutally finger her sored pussy, ending with wetting Mark bed and Mary bodies lying in the afterglow, exciting for tomorrow. Mark then tried more sexy outfit as she masturbated again before returning a completely exhausted and sored body back to Mary, who immediately went to her bed after the transfering sequence, before that, she didnt forget to say good night to her niece and ask him not to masturbate any more in her body because her pussy is soared right, Mark laughed and ensure her that he'll only need her to go to cosplay. The day ended as Mary close Mark room's door
