"Come up Jane," Alice called. "Mark and I are waiting for you."
Mark heard his mom on the stairs and panicked. He didn't want his Mom to see him naked in bed with Alice.
"What is she going to..."
"Don't worry," Alice whispered, patting Mark's thigh. "Jane's a big girl."
The door opened and Mark's mom, Jane, stood with her hands on her hips, looking at Alice and Mark, their naked bodies half covered by a sheet. Mark was uncomfortable, while Alice grinned wickedly at her friend.
Jane was dressed in jean shorts and a cut-off tee shirt that exposed her tan belly and hung taught over her shapely breasts.
"Mark," she said, "Tell me the truth. Have you been faking it with the sleepwalking? Just be honest and I won't be mad."
"Uh..." Mark looked down. He had been dreading the day when this conversation might happen. But now that it was out in the open it felt like a relief. He looked up and met his mom's eyes, "Yes. I was faking. All along. I was so attracted to you! I couldn't help..."
"Ok," Jane said, breathing a sigh of relief, "Don't apologize, I liked it just as much as you, if not more. So now we can stop pretending, can't we?"
"Yes we can," Alice sighed, "Now take off your clothes. Show us what you got under there, Mom!"
Jane unbuttoned her shorts at the waist, unzipped the fly and slid the tiny cut off jeans down her thighs. Her swollen pussy bulged in a black thong. Mark could smell his Mom's special scent and he was instantly hard.
Alice was a MILF from Heaven, but Mom's body, her smell, her luscious skin, her huge breasts capped with mauve-pink nipples, she was sexy on a whole other level. She brought him to new heights of hardness.
Jane lifted her t shirt, exposing her jutting breasts, encased in a black bra. She pulled the t shirt over her head and ran her hands over her body.
"Do you like when Mom undresses for you Mark? Do you like seeing Mom naked? Did you want to come in my room that night and jerk off on Mom's tits?"
Mark nodded like a puppy dog as Jane half-chanted, half-purred this incestuous litany.
Jane caressed her nipples through the lacy cones.
"I can't wait to get out of this bra. My breasts are swollen tonight, It's my fertile time of the month. If you cum in me tonight, I could get pregnant. I can feel it. Do you want to give Mom a baby?"
Alice watched Mark's cock harden as his Mom teased him.
"He likes that idea! He's hard as iron for you, Jane!" Alice breathed, "He fucked me good and hard, but he's bigger and harder than ever for you."
