Mark isn't really listening as once again, he is on the bed, moving in between his mother's outstretched legs. This time, he notices that they are not using the blanket to cover themselves. Not that it really matters, their heavy robes cover everything except their face and hands.

Momentarily distracted, he only catches the tail-end of her question. He simply nods.

"Okay then, let's try this one more time."

The boy kneels motionless over her as he feels her pulling his robe up. Not enough for her to see, but enough for her to touch his... To his shame, he feels an intense thrill as he feels her soft hand gently grab him and realises that he is getting hard again.

He feels more movement down between them and he realises that she is pulling up her robe between them, so that they can....

Unable to look at her, he diverts his eyes only to find that himself staring at her chest. Even under the heavy robe, he can make out the shape of her large breasts.

Realising what he is doing, he quickly looks away, praying that his mother hasn't noticed as he concentrates following his mother's gentle maneouvering, feeling his penis hitting something.

"Help me, Mark. Push." He hears her asking.

He tries to push but nothing happens.

"Again, Mark."

He pushes again. He is now aware of something warm and soft pressing against the top of his penis.

"Harder, Mark. Pussshhh!"

He feels his mother pushing back as he tries again. Looking down at her face, he freezes for a moment. He has never seen his mother look like this, her eyes wide open, her cheeks red, her mouth clenched.

"No, Mark. Keeping pushing dammit!" Her sharp tone along with the sudden pressure of hands on his butt forces the boy to move forward in one powerful jab.

Immediately he feels something give as something extremely tight begins to slide over the thick end of his hardon, causing the boy to cry out only to be drowned out by his mother's shriek of "Oh my God!!!!" as he slowly sinks into her...
