I got down on my knees behind her. She slipped a hand between her legs, grabbed my cock and guided it into her hot, wet, tight pussy. I grabbed her hips and continued to fuck her hard and fast.

"Oh, honey…oh god…is this how you are going to fuck your sister too? Are you going to fuck us both with your pet?"

I reached forward, grabbed a tuft of her dark brown hair and pulled her head back. My mom raised up a bit, arching her back towards me. I could see her tits bouncing around as I was fucking her.

"You pussy feels so good, mom. I can feel it milking my cock. You want this as much as I do".

She turned her back, looking at me she shook her head yes. "Fuck me, honey, don't stop…please. Fuck your mom good".

I leaned towards her, we kissed. When we did I could feel my cock stiffen even more, my mom felt it too.

"Are you ready to cum? Are you going to fill my pussy?"

"Do you want it? Beg for it."

"Oh yes honey, please, come in my pussy. I want to feel your big cock unload inside me."

I could not believe how hard and fast I was fucking my mother now. She kept looking at me, her tits bouncing around, the creature still sucking on them, she just kept moaning.

Finally, I could not hold back any longer. My cock stiffened like a steel bean, and then I felt it unleash spurt after spurt of my cream into her. My mom screamed, "I can feel it! Fill me, Marcus! More cum, more cum!" The feeling and desire cumming inside of her were beyond deion.

When my cock finished unloading inside of her, I pulled my still hard cock out her pussy. My mom spun around, still on all fours and sucked my cock clean. She kept looking up at me as she worked my hard shaft with her lips and tongue, sucking out the remaining drops of my cum and licking my shaft clean of my cum mixed with her pussy juice and the creatures load as well. She moaned as she kept licking and sucking.

Once she was done, she stood up in front of me. She glanced at my alien pet and then at me. My creature just 'sat' on the floor, I guess it was resting or just 'watching' us.

"Now what do you plan to do?"

"Well mom, I have several thoughts. I believe a couple of my friends are home as well. Maybe I will introduce my pet to them. They have always thought you are a MILF, but I think they need to be properly prepared for you. "

Her eyes widen, and she let out a little gasp then gave a faint smile.

"What about your sister, Chase?"

"Mmmmm, Chase. She will get special attention before anyone else. Do you agree with me, mom?"

I could almost see the conflict in her eyes. I was asking her to agree with more incest which is taboo. However, I knew the carnal sexual desires the creature brought out in us was overpowering her moral thoughts.

"Yes, Chase deserves it. She is a cock teaser. She comes home from cheerleading practice, wearing her skimpy outfit. Your sister should be taught a good lesson about teasing so many cocks. I know you can teach her that lesson along with your 'friend".

I placed my hand under my mom's chin. "You are such an excellent dirty mother. But right now I need to get something to drink."
