She wants a REAL sister.. She cums on you to complete the transformation

By: GiantessLover

The girls finally stopped their growth once they hit 100 feet tall. Alison was a bit dissapointed at the development and even took to having sex with Kim over and over to try and get some more growth out of the situation, however she didnt gain an inch. She did however keep her promise to you to let you enjoy her growing body.

She actually liked your change to being mostly female, even showing you ways girls could feel good by licking all over your body in all your new sensitive areas. She then gently slipped you into her pussy, pushing you in deep, using you to help her get some pleasure as she usually does. Alice has been trying to chase you down, to cum on you just one more time to turn you into her true sister. She wanted a real sister, not a shemale sister.

She walked into the barn, asking where she could find you, she wanted to have a lil fun with lil Will.

"ohhhhh he's um.....helping me out heeeeeere....woah Will that feels good...."

She grins and rubs her cock against your girlfriend's slit. You hear her protest, but Alice promises to be gentle....she convinces Alison that if she thinks about it, wouldn't it be hot to have 2 lovers inside her at the same time. How when she cums that she would be cumming on twice the amount of people she would have if she didn't let Alice slide in. You scream in protest but alas, your voice cannot be heard through the folds of your girlfriend's pussy. She finally laments and lets Alice push in.

You get pushed in deep, and you stare at the purple headed beast as it gently moves back and forth, pushing against you with each gentle thrust. The purple head of the beast begins to swell, you feel your girlfriend's pussy contract around you with an orgasm, and then Alice can take no more when the slit opens and sprays you all over with her cum. You feel your cock slowly begin to shrink, as your breasts swell even larger, R cup wonders sit on your chest, the biggest of the girls. Your balls slowly shrink...and shrink...until they are no more. Your cock vanishes as well, you desperately feel but only feel your pubic hair and pussy slit. Alice has won....you are now a woman....
