Mom and I were still in tight embrace standing in the middle of the balcony recuperating from our slow dancing and fucking.
Beside us, my girlfriend Mindy and her dad Chris were still in their usual position. Chris carries Mindy with her arms around his neck, her legs wrapped around his hips, his hands on her butt supporting her weight. Her pussy stretched and wraps around his hard cock as he slowly sways her around the balcony dancing with the soft music.
Suddenly, we heard the familiar phrase we heard earlier.
"GET A ROOM!"
We all turned to look where that voice coming from.
It was my older sister Abby, standing by the door, smirking. Beside her was Mindy's older sister Laurie, giggling softly. Both of them naked.
"We already heard that." Mom said laughing.
"MmmHmm! I already told them that earlier." Mindy said while still impaled on her Dad's cock.
"Oh...Look who's talking!" Laurie said to her sister in a singsong tone with faux reprimand. "You too Dad! both of you should be ashamed of yourself. I can't believe you're engaging in a sinful incestuous act, with your very own daughter of all people."
"I know, right?" I said chuckling. I always enjoy this kind of banter and teasings within my girlfriend's family and mine. "And that's very immoral." I added with a big smile on my face.
Abby turned to looked at me with a raised eyebrow. "Well...well...well, and also look who's talking here!" She said also in a singsong tone. "And you think what you and Mom were doing not immoral, huh! little brother?"
I looked back at her and still can't help admiring her nice hour glass figure, her nice medium size boobs, then glancing downward to her nicely trimmed bush. I looked back up and find her so attractive with her short brown hair styling a boyish haircut. It really complimented her beautiful face. "Of course it is immoral, if we're talking about what the outside world think. But not within our families. Right?" I responded.
"That's right!" Mindy said and her dad agreed laughing. This time Mindy already disengaged from her dad and both of them standing with their arms around each other. Mindy looked so girly in a ponytail, but pretty as well. Nice rounded boobs and shaved pussy. About 5'8" in height just like my Mom. Her dad beside her is about 5'11" just an inch taller than me at 5'10"
"See?" my girlfriend and her dad agree with me!" I snickered.
"As long as nobody knows what's going on behind closed doors nobody can judge us of immorality." Mindy added.
Laurie turned to look around and saw trees then looked up and saw an open sky. "I don't think we are behind closed doors." She said chuckling obviously being funny.
"You know what i mean!" Mindy said laughing,
We all followed laughing. "That's a good one Laurie" I said as I looked at her and also can't help admiring her gorgeous body with nice big boobs and shaved pussy. Her dark brown shoulder length hair looks pretty on her. She's tall, same height as my sister Abby at 5'9"
Of course with in our two families it's been understandable that having sex anywhere in the house whether in the living room, kitchen, laundry room, balcony, backyard pool or even outdoors as long it's private with no outsiders can see us, it's all part of the room. Also means our "Closed doors."
Laurie turned to look at her dad and sister, then glanced down at his cock still hard and shiny with Mindy's pussy juice coated on it. "You guys did not finish?"
"No Pumpkin." Chris said to her older daughter. "Your sister said earlier that she just like to be playful and would only want a loving hug while I'm inside of her."
"Oh poor Daddy." Laurie said pitifully then turned to her younger sister with a mock reprimanding look.
Mindy lovingly caress her dad's chest with her right hand and said to Laurie. "Well...what's a big sister for?...if you can't pick up the slack and take care of our Daddy!"
Laurie with a big wide smile turned to look at Abby. When their eyes met, Abby rolled her eyes and threw her hands up on the air with faux exasperation."Here we go again, looks like there's another sinful incestuous act is going to happen!" Shaking her head. "What's happening to this world, It's full of incest!"
"Incest is the best!" I said looking and smiling at her.
"Of course you can say that little brother, it's very obvious anyways." Abby said smirking glancing down where my dick was still buried inside our Mom, although it was just haft hard by now.
"Correction honey, your little brother is not that little anymore and you know that, don't you?"
"Of course Mom I know that."
"And honey, if you keep on teasing us, specially our guys, you might end up not getting a dick at all." Mom joked.
"I can live!.. I got my own dildo anyway." Abby replied.
"Oh nooo...not me! I need a live dick!"
Laurie exclaimed faking mortified.
That causes us except Abby to burst into laughter.
Abby tried to keep a straight face but she chuckled, then eventually laugh with us.
Then Abby followed by saying, "Besides, you all know that I like pussy more than a dick."
"We know honey, but you seem to start liking dicks too. correct?" Our Mom said trying to make Abby to admit it.
"Yes Mother! Thanks to Laurie for convincing me..." Abby said as she turned to look at Laurie who supposed to be beside her but nowhere to be found. Glancing towards Chris and Mindy, "Oh there she is!" Abby said rolling her eyes again. "Ready to commit incest."
Laurie was kneeling in front of her dad with her nose almost touching the shaft of his cock sniffing it.
"Hmmm...musky...smells pussy." She said without taking her nose from the cock.
"Of course it should smells musky... because its been inside a pussy., isn't it Daddy dear?" Mindy asked her dad with a teasing smile.
"Yes pumpkin. You know I always love the smell of pussy." Chris replied
"Oh yes... specially pussy of a family member." Abby interjected.
"I love the smell of your pussy too Abby!" Chris said glancing and smiling at Abby.
Abby glanced back at Chris, with a shy smile she responded. "I know Chris, you do."
"I love the smell of your pussy too Abby." i said in a sincere way.
"Yes I know dear brother." Abby fondly replied and looked me in the eye and added, "panty sniffer!"
Everybody laugh.
