Her bedroom

Lisa leads you to the master bedroom. It's a strangely erotic sight to see your own mother walk through the house fully nude, her erect cock swinging from side to side. You follow behind, watching her motherly bottom sway back and forth.

Once inside, she turns and looks at you. "Strip, Sweetie. I want to see your naked body."

Your heart races as you quickly shed your clothes and stand before her fully naked. Her eyes roam over your body, lingering on your hips and your bottom.

"Your body is so beautiful," she says. "So smooth." She runs a finger down your backside. "I'm going to love fucking your tight little butt."

"Thanks mom," you murmur. You have already imagined a hundred different ways you'd like to feel her cock sliding back and forth across your rear end. You know it will feel wonderful. The only problem is that you are afraid of what it will feel like to have your asshole stretched open. What if it hurts?

"I promise, baby, there's nothing to worry about," she reassures you. "You'll enjoy it so much. Trust me. And once we're done, I'm going to make sure your ass is kept stretched out properly. You'll be able to take my cock with ease for the rest of your life."

She pushes you towards the bed, her hand running along her cock as you go. You lay down on your back, waiting for instructions from your mother.

"First things first, baby, on all fours. That's the position for today. I'm going to lube you up."

"Okay, mom," you say as you crawl onto the bed, placing your hands flat on the mattress in front of you.

She takes a jar of Vaseline from the nightstand and gets on the bed behind you. You watch as she spreads the lubricant on her hands and presses them against your buttocks. You wince slightly as the cool liquid touches your skin. But when you feel her warm hands and fingers spread the slippery stuff around, you relax.

She rubs your cheeks with both hands, spreading the lubricant all over your butt crack. She massages it around until it reaches the small crevice between your cheeks. She pours some more onto your ass, pressing it firmly against the opening.

"Relax," she says softly. She begins to press her thumb into your ass. You feel a strange sensation as her thumb slowly squeezes into your ass. She pushes her other palm around the rim of your anus and holds it there. The pressure grows as she pushes further into your rectum with her thumb. It feels uncomfortable but not painful. After a moment, she withdraws her fingers and applies more lubricant with her palms and thumbs.

Then, without warning, she pushes two fingers into your ass. She's so gentle, you don't even notice until she's all the way inside you. "That's good, baby," she purrs. "Just relax for me..."

With that, she begins thrusting her fingers in and out of your hole. "Mmm... Mmmm..." You moan, enjoying her ministrations. It feels good to be touched there, and she knows just how much it excites you to be penetrated.

She keeps pumping and soon adds another finger to the mix. Now, her fingers are moving rapidly inside of you. Your ass feels full, and you begin to wonder how many fingers could fit inside. Would three or four work better? How far could you stretch? Could you take five? Six? Eight? Ten? Would you even want to try? Would you want to be a real ass slut? A cock-loving butt whore?

"That feels good," you moan when you realize that she has four fingers in your ass. The pain is almost forgotten. Your mother has a very soothing touch, and her caresses are making you forget everything but her warm hands and her hot cock.

"This is so hot, Doug," she coos. "Your ass is the sexiest I've seen."

Her fingers are still moving inside you, but now you can see her stroking her cock with the other hand, pumping and rubbing. "You're a good boy, Doug... You like being fingered, do you?"

"Yes mom," you answer. "Very much."

"That's good," she purrs. "I'm glad to hear that."

As she speaks, her thrusting fingers increase their tempo. "I could do this forever, baby, and I might. But, I need something more." She removes her fingers from your ass and grabs your hips. "I think it's time for my cock."
