Olivia growing bigger, and a friend arrives

Jack helped Olivia back up a bit so her but was directly under the shower spray.

“Ooh Jack, my butt is getting bigger” said an amazed Olivia, watching her butt go from (Rank A, level 3) passing (Rank A level 5) stopping at (Rank B, level 2), “Oh shit, my butt...it’s huge” smiled Olivia running her hands over her inflated butt cheeks.

‘I have always been to scared to do this, ever since the doctor told me, but now...wow, so..big’ thought Olivia, she couldn’t keep her hands off her butt.

“ you should enjoy it, don’t think of it as a curse, anyway, why don’t you come closer and ride the cock” smiled Jack pulling Olivia closer, pushing his hard cock between the girls legs, her hot wet vag lips licking his shaft.

“Oh my...ah...” shivered Olivia, the sensations was making her turned on.

“See, this is one way to have sex with a cock this size, from the look on your face, I see your enjoying it” Jack said while watching her.

“I loooovvee the cock, sliding between my pussy...it’s so divine, better than my dildo ever could” said Olivia, then she realized she had been pushed back under the shower spray, water was hitting her big butt again, she could feel herself swell again, “ah, Jack, I think you moved me back under the shower, I’m swelling again” Olivia said, still lost in the feeling.

“Of course, as I said, don’t waste it, enjoy it” said Jack leaning over and kissing her lips, she kissed him back, loving the feeling.

Jack watched as Olivia’s butt went from (Rank B, level 2) to (Rank B, level 3), she kissed Jack again, her little wet cunt rubbing the cock was really pushing her over the edge, she really wanted to fuck this wonderful cock.

“Hello...Olivia, you here, my class ended a few min ago, hello” said a female voice.

“Oh shit, it’s Ava, class must of ended” said Olivia, they both turned just in time to watch the curtain of the changing area, standing there was a female student, she had short black hair, yellow t-shirt and short black shorts, she had a shocked expression on her face.

“Oooo shit...hay..is that Jack, the cock...” said the shocked Ava.

Jack turned to Ava, “hello Ava, why don’t you join us”

“What the fuck happened to you Olivia, your all...bloated and...curvy...sexy...” said Ava biting her lip.

Olivia pulled away from Jack, turning to face her friend, she studded “I never told you...I have hydro absorption expansion syndrome, my body absorbs water and makes certain body parts expand” she said with a small smile, she was now standing there, nude, her big butt wiggled a bit as she shifted, she could see Ava’s eyes on her enlarged butt.

“Why disentangle you tell me” asked Ava to her friend.

“I..I thought you would make...fun of me” said Olivia embarrassed.

‘I see Ava is distracted by Olivia’s growth, she looks embarrassed and jealous of her friends growth, time to introduce her to the cock’ thought Jack, as he turned around, his hard cock pointing in Ava’s direction, he could see Ava blush.

“Holy shit...look at that thing” said Ava, ‘I am here...with a naked Jack, the cock is pointing right at me, it’s gigantic..in human size’ thought Ava.

“Well, I need someone to finish washing this thing, I still have Ms Jennie’s juice’s, I mean someone’s juice’s on my cock” said Jack, his cock hard and throbbing.

“Oh shit, you fucked Ms Jennie with that thing..shit, no wonder the class was cancelled” said a smirking Ava.

“No comment” said Jack returning the smirk, “now strip and join us”

“You don’t have to tell me twice” giggled Ava as she started stripping out of her clothing, soon she was standing there nude.

She had a good size chest, (rank A, level 5) her nice butt was also (Rank A, level 5)

She stepped into the shower, surprising Olivia when she smirked and started rubbing her enlarged butt, Olivia kissed Jack again while Ava was souping up his cock, rubbing and scrubbing it, looking on at her big friend, kissing Jack.

“Ok, everyone move around, let’s put Olivia under the shower again” said Jack as he helped Olivia to move under the shower again, “ I think it’s time to give Olivia some extra boobage, let’s get those tits under the shower”

Jack helped Olivia position her breasts under the shower head, Olivia gasped.

“Oh shit..my boobs are growing” said an amazed Olivia.

‘Oh shit, I’m so wet here...just looking at that big but, my pussy is so wet...wait, her breasts..oh I can’t wait to see them grow’ thought Ava.
