Yes. Let your sister leave.

As your sister climbs up the stairs you stand up from your seat, motioning to your mother to come towards you.

She obliges, walking straight up to you and pressing herself against you. It seems strange to have this sexy, submissive and confident version of your mom so close to you.

"I am so happy you are ready to use me John. I have been waiting for this moment for so long."

"Mom, I..." You can't seem to say the words.

"Yes, honey, I know you want me to suck your cock."

"Yes, suck me Mom."

Your mother stands back from you. She removes the little apron she was wearing. and ties up her hair. All while looking straight at you in the same way she was when she was sucking on her fingers.

She kneels down, and takes you out of your pants.

You are so erect it hurts.

"If this sucking this cock is ****, then I was made for it."

With that she is already sucking your cock head. Licking and slobbering obscenely. She moans as she sucks. All while looking at you straight in the eyes. He face was flushed, her pupils dialated, as if to say that she had know she had pushed herself beyond her limits, and now was struggling to hold on.

You could feel the cum building deep inside you.

"Yes, Mom, keep going I am going to come."

My god you can feel her swallowing, the feeling is incredible and it sends you over the edge. No point in holding back, your cum is jetting out of your cock, down your mom's throat. She's taking it and moaning as she does.

You are done and she is catching her breath in front of you.

"Oh my god John that is the hottest blowjob I have ever given. I am so glad it was you who got it."

"Anytime you want my mouth it's yours John" your mom says, collecting the excess cum and drool that had puddled in the corners of her mouth.

"Don't worry mom, I'm addicted now, believe me." you respond.

She stands up and says, "Mommy's going to go make herself look pretty again"

You gently slap her ass as she saunters past you. She looks back at you and gives you a little wink.
