Your girlfriend stared at the fallen bodysuit on the floor for some seconds.
"Right! Now I remember" she said as her memories came back, she remembered all the things she did while using the suit and the fun she had with you, she noticed that her personality went back to normal after she wore off the skin suit, but even with the suit she was still herself with some bits of your mom's personality.
She lifted the suit dripping some drops of cum, stretching it again thinking on wearing it again, she actually loved having a milfy and mature figure, so why not keep going? Before she closed the suit she had another idea, as she looked at you sleeping through the opened door of the bathroom, what would happen if the two of you wore the suit? The question excited her.
She carefully approached you trying to not make a single noise, slowly getting on the bed on top of you, she turned around standing up on the bed, making you face her back that wasn't zipped yet. She let her body fall on you, and quickly you were absorbed by the opening in her back, she zipped it immediately, she didn't know how it worked but had the feeling it would. Even that the suit had two people inside it looked like your normal naked body.
Now you were two separate minds inside a single body, with some of the personality traits of your mother, it didn't take long to wake yo up.
"Huh? What just happened" you asked with the feminine and mature voice of your mother. "Sweetie, where are you?"
"Right here sweetheart~" she giggled teasing you.
"Where are you?"
"Isn't it obvious dear? Not I'm not the only one in your mom's suit, We're both in it!"
"This feels strange but also..."
"Exciting? Pleasant? Hot~"
"Absolutely all of them~"
"Oh good it feels good to be back~ I'm glad this worked" she grabbed your now shared tits, you could feel her touches, and hat it felt to have boobs. She kept rubbing her nipples, a good sensation that turned into something bigger, a hot feeling in your crotch. "Oh~ what's this" she started to touch her parts, now YOUR parts, the sensation of having a vagina was more intense than having a penis.
"Oh babe I feel sooooo~ horny right now" you said, it seemed that your two libidos combined in the single body, feeling twice as good.
"Definitely hun~" she now introduced some fingers inside. Then she realised something, that your pussy were deeper than before, it didn't felt like a pussy inside but a deep pocket in your crotch, she kept introducing until she inserted her whole hand! Then half of her arm, your girlfriend just found something and grabbed it. She took her arm back and gave a surprise for you two, she pulled out your cock from her pussy, now she could feel your cock like was a part of her too.
"This is just amaaaaaazing~" she controlled the suit's left hand rubbing your clit, while now you controlled the right one to masturbate the cock that emerged from your vagina.
It was an absolute sensation that you couldn't describe but felt better than anything you experienced before, as you were touching your two sex organs, she started to rub even faster as you did the same with your cock.
"Oh hun! I'm think I'm gonna cum!" She kept touching yourselves.
"M-me too babe" you masturbated faster.
Seconds later a stream of cum was shot from your cock, at the same time you two squirted through your vagina, covering your parts in a mess of many fluids.
"Oh babe~ oof hoof" you tried to talk as you sweated, "you have the best ideas".
"I knew you would like it hoof I love to try many kinky stuff"
"And you're right my little girl~" you sounded like your mother, "we should stay like this for a while"
"Sure!" She moved her hand to your crotch, pushing your cock back inside with one finger until it was fully inside like before, it looked again like a normal trimmed pussy from the outside, you couldn't say the same for the inside.
Even if you were now two minds controlling one body you did a great job coordinating your moves, getting out from the bed and stretching a little, thinking on what to do.
