Skip to next morning

Jack awoke the next morning, laying on his right side of him was Mia with Crystal laying on the left.

“Morning beautiful” said Jack planting a kiss on Mia’s cheek.

Mia opened her eyes she smiled as she kissed Jack back, she reached her hands down to wake up the perfect cock but was surprised to find her sisters hands beat her too it.

Crystal’s hands where slowly rubbing up and down the shaft then pulling it closer to her, she wiggled her hips as she pulled down her pajama pants down a bit, her expanded pussy lips slightly wet, she started rubbing it between her legs.

Mia looked on in jealousy, her own pussy was a little wet and her breasts had shrank during the night, now back to its normal size.

‘At least my expanded cunt is still the same, by my breasts have shrank...oh well, if my sister keeps that up I might get to have big tits for school’ thought Mia as she watched her sister rub the semi hard cock on her big pussy lips.

That’s when Charlotte poked her head into the room. “Morning girls, and Jack, remember you have school today, make sure you have a shower, breakfast will be ready soon” she winked as she left.

Crystal sighed getting off the bed and headed into the shower.

————-Crystal POV———

Crystal left the bedroom, walked down the hallway and entered bathroom, turning on the slower and setting it to nice and hot just like she liked it.

Stripping into of the shower, letting the hot water run down her body, her breasts and butt had shrank a bit. Her pussy was still big, puffy, and bloated. Running her soapy hands over her body, every time she passed over her vag made her shiver.

Finishing in the shower, she stepped out and dried off. Wrapping a towel around herself she walked back into the hallway, then back into the bedroom.

As she entered the room, she scowled as she noticed her younger sister was bouncing up and down on Jack‘s cock, her breasts and butt where back to the same size as yesterday.

Walking over to her bouncing sister, pulling a squirming and moaning sister off the perfect cock.

“Enough sex, we have school today, go and get showered” Crystal told her sister while shoving her sister out of the room, but as she did her towel fell.

———-Mia POV————

When her sister left the room, she could feel her pussy tingle with need. She then stood up on the bed she put a leg on ether side of Jack crouch. Her pussy just inches above the mushroom tip, her wet sex now dripping onto the hard cock, with a giggle she slowly bent her legs. She let out a ‘sigh’ as she felt the cock go into her pussy, passed her lips going deep, the cock head just lightly pushing against her womb opening.

She then started bouncing up and down, feeling Jack‘s hands on her legs, reaching up to swat her butt every few sec.

She looked down and noticed her breasts swelling, reaching her hands around to her butt, she let out a happy giggle as she felt her butt cheeks swelling under her hands. But after about 17 mins of bouncing she looked looked up to see her sister in a towel enter the room. Stomping over to the bed, she pulled her off Jack’s cock.

“Enough sex, we have school today, go and get showered” Crystal said while being shoved out of the room.

‘Sigh, that was fun while it lasted, going to pay her back for that’ thought Mia as she entered the bathroom, having a quick shower, washing her big tits with a Luffa sponge, rubbing and scrubbing it between her legs, her thighs, her big round butt cheeks.

After drying off, wrapping her self with a towel, she headed to her room to get dressed. As she left the bathroom, she noticed her sister walking Down the stairs, her big butt wiggled as she walked.

‘No sex ah’ she giggled to her self as she entered her room and quickly dressed

_Then after her sister was out of the room, she turned around and “and you, use the downstairs shower, don’t let me catch you fucking mom” she said pulling _Jack off the bed.

Tho she didn’t know her towel had fallen, or how close Jack was to cuming. So when Crystal turned to her dresser, opening the top drawer where her panties where, she let out a squeal as she felt Jack‘s cock enter her now exposed pussy. Feeling it go almost all the way in, feeling the cock swell as it started filling her insides, looking down she let out an excited squeal as she watched her breasts expand, as more cum was pumped into her pussy, the bigger her breasts got, stopping at the same size as yesterday.

“Thank your sister” said Jack Into her ear, as she felt him slap her now big round butt as he left the room.

_Frustrated Crystal dressed and fallowed _Jack downstairs
