Althea had just discovered Mom spying on her and I fucking and Mom was naked masturbating, and her squeaks when she came were so loud that she blew our plan. Althea had demanded to be included in a permanent threesome. I was happy about that, of course, but Mom was not so sure this was a good thing. She went along, though.
Althea said to Mom, “I wouldn’t mind fucking Harley, Ramona, do you think he should be brought in on this, too?” “Oh, my God, no! This would blow his mind! His head couldn’t handle it, he would either go berserk and kill us all, or, more likely, he would just kill himself. He has no imagination whatsoever. In the twenty years we have been married, it never once occurred to him to wonder if I enjoyed our 2 minute fucks. He just assumed I did. He has always worried that I would take up with handsome older men like his first wife did, so when he sees me and Georgie with arms around each other, he sees mommy with his little boy and thinks I’m too busy with childcare to think about other men. He hasn’t noticed that Georgie has been a man for the last couple of years!”
Althea said “Evidently, I just helped put on a show for you, so now I think it’s fair you do one for me. I want to watch you fuck your own son.” She dug in her purse and came out with a huge rubber cock. “I thought I might have to put on a show for Georgie with this to get him interested in an old woman, but look, he’s raring to go again, already! Come on, Ramona, ride your horsie while I watch!” Mom came over and stroked my cock, then bent over and I drove the meat in. Mom had one hand on the wall, the other on my cock as it slid in an out. We were both breathing hard. Althea shoved that big rubber cock up her cunt and said “Oh God, you’re fucking your own son, and he’s fucking his own mother, I’m starting to cum already!” Then she grabbed me and started shoving her tongue down my throat, Then grabbed Mom and did the same to her. Mom gave a gasp, then shivered and went back for more. She came with a gush around my cock and wrapped both arms around Althea. I grabbed the cock away from Althea and had to kind of squat because she was way shorter than Mom, and then drove it into her. Mom was still squeaking and cumming, and I shot my load into Althea. We all flopped on the couch, and Mom spoke for all of us. She said “Holy shit, I never came like that in my life! I think we have discovered something here! My pussy is so happy, I think I’m going to grow another one!” “Sounds like a plan to me”, Althea said. I just couldn’t stop grinning.
