You Choose How Headswap

After using the device, you swapped heads with your sister Nancy.

}You: 25 years old, caucasian, light brown short hair, average male head and face features atop a petite girly 5'4" height body with D-cup breasts wearing a light blue low cut short dress and heeled boots.
And Nancy: 18 years old, long curly light brown hair, skin tone exactly the same as yours wearing light makeup with an average 6 feet tall male body wearing a navy plain t-shirt, jeans and black tennis shoes.

"Now lets call Felicia" you say and started a video call with Felicia, forgetting the device still in your male hands, now with Nancy.
You grab your smartphone and put it in a holder and start the video call.
While ringing, you adjust it to film you lying in bed. The way you're lying makes Nancy's body under your neck shows the best of now your cleavage and curves.
"Hey Fra-..." Felicia was about to greet you when she answers the call but she stopped talking with her eyes opened wide in shock seeing you like that.
"Hi sis!" you sheepishly wave your dainty hand to greet her, but she still look shocked staring at Nancy's body under your neck.
"Uh... Felicia, are you ok?" you move now to sit like usual with legs spread, making she see your panties.
"Oh my god! Frank!!! Are you cosplaying as a girl or something like that?" she asks covering her mouth still astonished
"You'll not believe if i tell you what is this!" you say cupping your boobs.
"Bro, sit properly! You're showing your panties!" Felicia says and you can hear now Nancy laughing. You blush and gets on all fours, making Felicia see your cleavage now closer.
"Uh... Oh... Sorry! I'm not got used to Nancy's body yet." you say and Felicia got shocked again.
"Nancy's?!?! Wait... What?!" Felicia now looks puzzled
Suddenly Nancy shows up, hugging you from behind and squeezing your boobs, make you moan in an almost high-pitched tone.
"And i'm here!!!" says Nancy as she does that.
Felicia and Nancy laughs hearing you sound like that. You blush and put your female hands over Nancy male arms wrapping you.
"Don't do it sis!!! I didn't expect that!!" you say tring to cover your boobs, but she kept her hands holding your boobs.
"Oh my god! You two look so funny like that!!! You can now turn off this video filter..." Felicia says
"But that's not a filter... We swapped heads!" you say
"How can a filter let me do this..." Nancy says and squeezes your boobs again, and you moan loud.
"Stop it! They're too sensitive! How you girls deal with it!?" you say and takes your sister's male hands off your boobs.
"It feels good when you get used to let guys do it..." Nancy says winking, Felicia laughs and you blush.
"No way i'm let a guy do that to me!" you say crossing your arms
"I still not believe in what i'm seeing..." Felicia says

And to finish the call...
