Mark walked over to the wall, dimmed the lights, slightly, and opened the door a crack.
Understanding, on unsteady legs, I moved to the spot on the carpet we had marked so long ago and knelt.
Mark came up in front of me holding his penis just under my nose, speaking clearly to me and rubbing his precum over my upper lip.
My place on the carpet was chosen so that I would be on full display for anyone looking through the crack in the door, and also that I could see when our audience would arrive.
I watched the crack intently, knowing that I would have to wait until Adam took his designated place before his father would give me my relief.
My pussy was in pain, my ass was twitching uncontrollably, awaiting that moment when I fall over the edge of my long-delayed orgasm.
Finally, a shadow in the corridor, I raise my hand to touch the monster in front of me, Mark grabs my hair.
“Slut.”
“Yes?”
“Open your mouth.”
I do, and he slowly pushes his cock between my lips, it’s big, it almost painfully stretches them.
From my position in the room I see a wide eye staring at us, at me from the dark hall.
“Slut”
I look up at my husband with a mouthful of cock and grunt a question through my nose.
“Suck, slut. I need your hot mouth and your hot throat.”
I raise my arms and grab Mark by his ass, holding on to him, as I impale my face on that sweet hunk of meat.
Every time we have sex, Mark takes the first thrusts slow, we adjust our positions and then he pounds me.
I slipped him in, he pulled out, I stretched my jaw and he pushed back, my throat was prepared, he drove in, my spit was drooling down my chin, over my tits and between my legs, I was a rag doll for his pleasure, I lost myself in his lust for my body and then I everything went dark for me.
That night I slept like a baby, a wicked baby. I dreamt about cocks and cum all night. I woke up in the morning wet and horny. Mark had already left for work and I could hear the ‘children’ downstairs in the kitchen.
Putting on a short and ‘decent’ robe, I went down to check on them before they left the house.
Adam, as always, almost ignored me, but now that I was on to his game, I kept watch over him out of the corner of my eye.
Not knowing that he was busted, it was easy for me to catch him ogling me. I even gave him some easy scores, when I knew that Annie wouldn’t notice.
As they left the house, I locked the door and dripping wet ran upstairs to my room. Out of my “toybox” I pulled out the double dildoed “chastity” belt that I have, and with trembling hands I stuffed both my ass and pussy as fast as I could. Fastening the toy around me, naked I went to my son’s room.
Naked I sat in his easy chair, opening my computer on his desk and searching his library of “mommy and sister” porn.
His room was muskier than the other morning, he must have milked himself dry last night, after the show my husband and I treated him to.
Sitting naked in the lowlight of his room, rejoicing in the scent of his cum, I imagined him as he tugged at his cock, with both hands, milking himself for me, streams of cum flowing from his firehose dousing the fire in my heart.
