Skip to fucking Crystal

As Crystal continued attacking Jack cock with her mouth, rubbing her hands up and down his throbbing shaft and licking the mushroom tip. She slurped up his pre cum like melting ice cream. Mia bent down, rubbing and running her tongue up and down her butt cheeks, then down between her legs. Putting a finger into her wet sex, making her moan into Jack cock.

Jack seen the look on Crystal’s face, she was getting to a point of sexual frustration and the need to be fucked. So reaching his hands down, pushing Mia’s face away from where she was eating and teasing her sister. He used his pussy power, he rubbed his fingers along the girls vagina lips.

Mia smiled, letting out a small squeal as she watched as her sisters pussy lips got bigger, bloating and expanding bigger. Her pussy now bigger, not as big as hers but big enough so she could ride the cock.

Jack took hold of Crystal’s hips, pulling her crouch closer so it was now over her vagina.

“Hay, what are you doing... my pussy is too small to fit that monster fffffuuuuuccccckkkkk” said Crystal, but before she could finish talking, he pushed down on her hips. The mushroom cock head slipped inside her very swollen vagina, passed her big swollen lips. Slowly sliding down the shaft, Mia leaned close, running her tongue up her butt cheek again. Then sitting up and started running her tongue around her sisters breast, flicking the nipple with her tongue, lightly biting the nipple.

As Crystal slowly bounced, Jack said “Hay Mia, your a little slut baby and need to suck on your sisters breasts”

Mia giggled as she said, “Big mommy Crystal, me baby, need milky” then she went back to sucking one of her sisters breast then switching to the other.

“You know, you can get bigger breasts, so you can feed your sister if you make me cum...inside you” whispered {first1_name into Crystals ear.

“Better not make this little girl go hungry” said Crystal as she started to speed up her bouncing.

“Shit...your cock...is so...hard...hot...ohh...going...to cum” said Crystal, her tongue hanging out and drooling.

Mia looked up from where she was sucking her sisters breast, her sisters breasts where slick in her spit. Mia smiled as she could see her sisters eyes roll up as her body shook as she orgasmed.

“Fffffuuuuuccccckkkk....cccuuuummmmiiiinnnngggg” shouted Crystal.

Jack could feel Crystals vagina clamp down on his cock as she shouted out in orgasm, hot pussy juice leaked down his shaft.

Then Jack started to cum, load after hot load splashed inside her, filling her up. Her stomach swelled a bit from all the cum. Mia reached down and poked her sisters stomach, then pushed her hands into her chest, forcing the load of cum into her breasts.

“Aggh” moaned Crystal as her breasts expanded, swelling to (Rank B, Level 4) in size, almost pushing Mia off the bed.

“Mmmm...milky” squealed Mia as her sisters breasts started leaking milk.

Crystal had stopped bouncing resting her hands on the top of her breasts, her body still shaking a bit, coming down from her orgasm high.

After pushing Crystal off his lap, his soft cock slipping out of the girls vagina, his crouch was covered in pussy juice’s and sperm. Looking down at Mia, still drinking her sisters milk. Crystal was passed out on the bed, breathing deeply. Jack bent down, pulled Mia up into a deep kiss.

“Sisters milk tastes good, no wonder baby’s love it” giggled Mia, licking her lips.

“I am going to go take a shower” said Jack, looking down at himself.

“Yea, moms going to be home soon” Mia agreed, she didn’t want mom catching them nude, with a boy in the same room.

“Your mom” said Jack, ‘(Mia and Crystals mother is a wet nurse, at the hospital nursing room, and the local daycare)’ thought Jack.
