After relaxing and regaining my strength for a little while longer in the recliner I decide to pick up the clothes that were discarded around the house. I don't bother to put my own clothes on as I make my way up the stairs so I can get a shower.
I throw Max's clothes in his vacant room as I turn to make my way to my own room. I find Max at the end of the hallway still naked sporting a flaccid but still very large cock. Max is standing outside of the family bathroom awaiting a shower, which is currently occupied by Liz.
"Have Fun Daddio?"
"Are you kidding? That was a blast! I haven't had that much fun in a while"
"Good, I'm glad! I'm also glad your approving of this because Liz and I have been hiding it for a little bit now"
"How long have the two of you been intimate with each other?"
"Well it first started maybe about a year ago, we would watch each other masturbate. Not long after that Liz brought home this porno that was circulating around school that two of her friends are in. When we were watching that porno together we got really hot so we took it past masturbating in front of each other and had sex."
After hearing this I realize I'm still holding onto Liz's clothes as I place her skirt and sweater down on a near by chair as I bring her thong up to my face and slowly deeply inhale her underwear. My daughter's thong is still a bit damp with her juices as her musky smell fills my nose and I begin to feel my rod getting hard again.
"I love when Liz wears her cheerleader outfit! It gets me so turned on, all my friends and guys on the team always comment on how hot Liz is and what they would do to her."
I myself am sporting quite the woody now from hearing this from my sons mouth. Before I even realize it I find my daughter's thong wrapped around my cock in my hand. The feeling of Liz's silky smooth thong on my cock sends shock waves through my body.
Max and I are now masturbating openly outside of the bathroom where my baby girl is cleaning up her body from the fucking we just gave her.
"Does your mother know about the two of you?"
Just then the door opens up as Liz stands there watching us while in a white string bikini with red cherries printed on it. My question goes unanswered as my daughter stands in the bathroom doorway watching us.
"You little horny devils can't get enough, can you? Look at you Daddy! Your jerking off your cock with my thong! Maybe you boys need some help?"
Max and I both let out groans of ecstasy as Liz alternates between blowing one of us and jerking off the other. I truly have never seen anything hotter then seeing my little girl with my dick down her throat as she is jerking off my son.
Liz then takes both of our cocks and connects our cocks at the heads and holds them there as she wraps her mouth around both of our touching helmets.
Liz began caressing the bottom of both of our cock heads with her tongue. While Liz focuses on our docking dicks with her mouth she takes her hands and begins pulling on our ball bags and lightly scratching them with her long french tip nails.
The only thought that runs through my mind at this point is if these little trysts between me, my son and my daughter are to continue how am I going to be able to keep this as a secret from my wife?
"Ahhhh Fuck Sis, No one blows cocks like you do!"
Liz giggles in response and looks back and forth into our eyes as her tongue does laps around our helmets polishing them with her saliva.
Liz then breaks the connection between our cocks and begins sucking on my ball bag. Liz is taking her time as she sucks on one ball at a time until she sticks my entire sack in her mouth while lightly jerking my shaft off.
The feeling of Liz's soft tongue massaging my testicles is amazing but the taboo of knowing it is my daughter who is devouring my balls makes it even hotter thus making me even harder.
Max grabs Liz by her hair as he pulls her mouth away from my ball bag and turns her focus onto his nut sack. I watch as Liz gobbles on Max's huge ball bag as she yanks on his shaft.
All of a sudden we hear the beeping of a car horn as Liz stops snacking Max's nuts as she stands up.
"Shit!, I'm sorry guys! That must be Heather. I don't wanna keep her waiting, we gotta get to the beach before the traffic. I'll make it up to you two later. I Promise! In the mean time while I'm gone, please don't blow your loads, save them for me! Oh and Daddy, You can keep that thong!"
Liz runs to her room and grabs her beach bag and runs down the stairs and out the door. Max and I stand there in front of the bathroom sporting our hard ons watching Liz's ass bounce in her bikini as she runs out of the house.
"Well, you heard the lady! We can't shoot off our baby batter, so take a cold shower and lets watch the Doubleheader in the living room"
"Sounds like a plan Dad!"
As I enter my room the phone starts ringing. I go over to the nightstand and pick up the phone to find that it is my wife Donna on the other end.
Donna tells me she has a surprise for my birthday I can't wait to find out what it is but I think we as a family have a bigger secret.
As I'm talking to Donna on the phone I lay on our bed and I bury Liz's thong in my face and continue smelling and tasting them. As I am doing this I can't help myself from lightly jerking myself.
Max enters my room in a towel that shows he is still pretty hard as he asks if it is Mom on the phone.
I inform him that it is his mother and he asks if he could talk to her.
I tell Donna that Max wants to talk her and that I should get a shower, I tell Donna I love her and hand the phone over to Max.
I notice as I hand over the phone to Max that he starts undoing his towel and starts playing with himself.
It makes me wonder if he too wants to fuck his mother or if he is still thinking about his sister as I leave Liz's thong on my bed as I enter the bathroom to start my shower.
While I'm in the shower I can't help stroking myself as i envision Liz and Donna blowing me at the same time.
I come pretty close to blowing my load in the shower but hold back at the previous request of my daughter.
I finish my shower and start drying myself and enter my room to find Max is still laying on my bed with Liz's thong in hand jerking himself off and he is still on the phone.
Max is in a state of bliss with his eyes closed and my presence in the room is unbeknown to him as Max is slowly jerking off.
"Mmmmmm Yea how does that feel? Do you want more you filthy slut?"
My heart skips a beat when I hear this as I try to remain quiet in order to listen in on more of this phone sex to see if Max is still on the phone with his mother.
I try to slowly move over to my dresser while in my towel but I foolishly trip on one of my shoes and alert my presence to Max.
"I gotta go, the Doubleheader is about to start. I can't wait to see you tonight!"
