Tiff and Katie go to Tiff's home and start preparing for a sleepover. her parents are out enjoying themselves for a week. Tiff is being a bit clumsy with her big breasts. they hear someone come in. Tiff forgot her little sister, Sarah(18) hasn't developed much yet, though she had a tomboyish thing going, she also has a boyfriend unlike Tiff, didnt go with her parents. Tiff looked frantically for something to change her breasts to something less big. she grabbed a lemon and shrank to a normal size. Sarah walked in and greeted the two girl.
Sarah:"hey, sis. hey, Katie. what are we eating today". it was Tiff's day to cook or get takeout.
Tiff still a bit flustered:"chinese or pizza?"
Sarah And Katie:"pizza sounds nice!"
Sarah:"so you are staying for dinner or-"
Katie:"overnight!"
Sarah:"been a while. want me to talk about my boyfriend or something again?" she grins at Katie
Katie chuckles:"of course hehe" and they disappeared upstairs
Tiff deflates a bit, jealous of the lack of boyfriend. a moment later Knocking came from the front door. Tiff opened and was greated by a huge ass wider than the door.
Tiff exclaimed:"HUH?!"
and the ass turned around and Jades face appeared carefully covered with shades and a baseball cap (Katie isn't the only one).
Jade:"spooked ye?!"
Tiff:"a bit. enjoying the attention or did you do this just for me?"
Jade:"just for you. hehe"
they sit down in the living room.
Tiff:" missed opportunity, i walked around with massive breasts for a while. was nice."
Jade:"daring"
jade just started to shrink her butt to something manageable as Sarah came in.
Sarah:"why are saying shrink so much and touching your butt?"
Jade flustered says "uh uh nothing" still at quite big of a size still.
Sarah:"...your butt is... big"
Tiff enjoying watching Jades struggling to hid her perversion says nothing.
Jade:"fine come here ill show you"
she takes out her phone.
Jade:"hey Tiff can you copy this?"
Tiff:"copy w-" she gets flashed with picture of huge dick from what looks like chat from Katie telling Jade about the prank. immediately Tiffs skirt bulges up a bit.
Tiff:"what the! hey"
Jade:"that what you get from not backing me up, meanie!"
Sarah:"i have a brother with boobs? little boobs though"
as a response Jade threw a big grapefruit from the fruit bowl, which made Tiff's breasts grow to a reasonable size.
Tiff:"hey stop it"
Sarah:"yoo those are nice" as she gets up to touch them. Tiff tries to resist but both get interupted by a snapping sound as her dick falls from underneath her skirt showing its head just slightly. Tiff hides her face but then attempts to hide the dick with her hands out of emberrasment.
Jade:"dont worry we both have boyfriends" she says looking smug at Sarah who does seem affected by the second hand emberrasment from her sister.
Jade:"oh lighten up"
Sarah:"you embarrassed my sister a bit much Jade"
Jade:"oh, fine"
putting her hand in her bra and say grow a few times. after removing her hands visible s bulges appeared slowly tenting her shirt.
Sarah:"you... aroused and those a quite long... nipples"
Jade bit red and quite:" there is quite a big dick on a cute girl"
Sarah:"oh ohoOo. you arnt getting to my sisters dick that quickly missy!"
At that moment the door bell rang.
