Body swap with his sister

added by paf_le_chien 9 years ago AR AP BM TG

When we are in, she marvels at the rudimentary machine, but remains skeptical about its use.
"This thing cannot exchange bodies!" She said.
We answer her that she has to try.
Harry tells me "Philip, go in a cabin"
I'm surprised "What! Why me?"
He replied that he did not want to become his sister. I eventually go in the cabin although either I didn't want to be his sister, but it is only temporary.

Flash! It works, I swap body a second time. I look down and I found two small bumps on my chest. Erin is not developed enough. But just seeing it makes me happy to have made this exchange. I'm examining my hands and my thin arms. I wear mini shorts and a pink top. I feel my hair run on my cheeks and ears. She has lighter than his brother, almost blond hair.
"Oh my god!" I hear Harry's voice from the other cab. Erin takes a few steps in his brother's body. She pulls his arms' hairs and then rubs his hands on his chest, looking in vain for breasts.
Again "Oh my god!"
I'm just glad, I knead my small breasts and I take big pleasure.
Harry seeing that said, "I regret that you took his body, it's too creepy seeing my sister fiddling like that"
We laugh.
Erin suddenly exclaims "But what's happens?" She looks at his crotch. A bump is unequivocally formed. I told her that she is getting hard.
"Oh but I didn't want to" she said surprised. This is the problem of all men I tell to myself.
She adds, "I'm too tight, I've to open my pants"
Harry is embarrassed. "Uh please, can you wait a bit, I prefer avoid seeing you do it." His sister agrees.
Harry then said "We need other people to swap. Grab your phone and call your friends" Very excited, we call some close friends.
