We took the elevator from the basement to the top level. The condo penthouse was jointly owned by Elizabeth, Cassandra, and me, without our husbands's knowledge. It was a place we acquired solely to house our longest running experiment. We may have reached case study number 60 in the labs, but here, within these walls at the top of these floors, case study zero was still running strong.
Jason was impatient, already squeezing my shapely, sculpted butt the moment the elevator doors shut. I was used to this and immediately scooted into the corner, out of sight of the single security camera monitoring the interior of the elevator.
Coyly, I picked up the front of my skirt and raised it to display my hot pink lace G-String thong that I wore for my primary "research specimen" before me.
“You’re sooo hot mummy,” Jason growled, immediately pushing his hand between my thighs and rubbing my plump, damp mound.
The elevator was saturated by the sound of our heavy breathing. I hooked my fingers at the crotch of my thong panties and pulled the film of stretchy fabric to one side, offering my son a glimpse of tonight’s treat. His mother's baby-smooth, sexy-plump pussy that is flushed pink and dripping wet for him.
Jason wasted no time pushing a finger into the naughty canal from whence he once came forth. That place that is taboo to all sons. This is the reason why the gates to the garden of Eden is sealed. It's symbolism against this type of "wrongness."
Well tough, because what I'm "symbolizing" to my son is that, tonight, my garden is open for business.
Jason frenched me while he fingered and played with his mummy’s clit, all the way to the top of the building.
When the doors dinged open, he grabbed my hand and urgently pulled me towards the palace that I have built for him.
Outside the door to our unit, I started to reach for the doorbell, but then I remembered something.
“Ooops, I forgot, gotta call your daddy and tell him we’re coming home late,” I said.
“Faster do it,” Jason said. He pushed his hand under my skirt again. I held my skirt up for my son to play with his mummy's sacred place as much as he liked while I retrieved my phone from my bag slung over my shoulder, and proceeded to call my husband.
My hubby, Francis, picked up after a few rings. “Dear?” He said drowsily.
“Darling, I... I’m sorry. I’m gonna be late. Something came up at the lab. Please don’t wait up.”
“Oh, okay, I was dozing off anyway,” Francis replied. “Wait, what about Jason? Did you fetch him?”
“Yeah, I orrgh....”
My son had stuck his two fingers, which were soaked with my pussy juice into my mouth. I dutifully sucked his fingers clean.
“Sorry,” I said breathlessly to the phone when Jason withdrew his fingers and went back to playing with my clit. “I already fetched Jason. He can stick with me like last time, there is a resting lounge at our lab and he can play video games on the TV there. He won’t be alone. Liz and Cass brought Lester and Sean as well. It’ll be fun for him."
“Oh okay. Tomorrow is Saturday and there is no school anyway. Drive safe. Love you.”
“Love... You... Too...” I said, trying to suppress my panting.
I ended the call. Then I bit my lip and enjoyed getting finger fucked by my 17 year old son for a little longer. “Jasonnn... Shall we go inside?” I moaned.
“Cum first, mummy. Right here,” Jason ordered.
“Yes dear,” I replied.
Jason fingered me to a good hard cum. As I squirted on his hand, I moaned and struggled to keep on my feet. When my delicious shudders subsided, I took his hand, brought it up to my face and started licking his fingers clean, locking eyes with him the whole time.
“God mummy. You are just absolutely stunning.”
“Thank you dear. You are such a good boy. Thank you for making mummy cum,” I panted.
After licking his hand clean, I retrieved the keycard and let myself into the penthouse.
The entrance way in the penthouse opened up to an indoor kitchen and a large living area. The TV was playing music videos, but on the couches in the sitting area, no one was watching. Cassandra and Elizabeth were sitting with their respective sons, Sean and Lester. Each couple were busy making out.
Lester has one of his hands under Elizabeth’s skirt, fingering her pussy quite roughly while she moaned into his mouth and sucked on his tongue affectionately. Meanwhile, Sean has both hands under his mother’s blouse, eagerly squeezing her gorgeous breasts as they giggled and nibbled each other's lips.
Lester looked up as we approached and gave Jason a nod and a smirk as a welcome greeting. Since our boys has been together in this "case study" for more than a year now, they were pretty much best friends at this point.
“Took you long enough,” Lester said to Jason.
“Sorry,” Jason replied, pulling me to his side possessively and squeezing my ass.
I giggled. “Well then, shall we get started?” I asked.
