She decides that she wants to fuck your ass.

"Oh, baby." She says and she stands back up, revealing that even after cumming gallons in your throat, she is still erect. "Mommy's still soooo hard. I'm sorry baby, but you look so sexy down there, I can't help but stay throbbing for you."

You whimper, but not in fear, but anticipation. You have a hard time believing that after how much she pumped down your throat, that she would still be back up again and ready.

"I don't want to be late for work dear, but there is no way I can go with this cock standing in place. hmmmm..."

As she continues to hum to herself, she walks around you, observing you in a lustful manner. 10 seconds later, she gets in your bed and moves directly behind you.

You now know what she wants. And You, shamefully, want it too.

"You have such a nice bubble butt Marcus. I wonder if you got that from your father or me? Doesn't matter, its sexy either way."

She puts her right hand to your back, bending you over while squeezing your left cheek for the other, you're now face down and ass up. You provide no resistance, though you do have concerns.

"you... you're going to-"

"Fuck your ass? Yes sweety, I am." She says in a matter-of-fact tone.

"But-but, I'm a virgin." You speak with a bit of fear.

"I know, I know. I'll try to go slow, but I can't promise that I won't lose control and destroy your ass." She says. Despite the matter of her words, she says it in a calm and almost caring way. It puts you at ease, despite knowing what she is going to do.

She begins gently rubbing her fingers along your lower back going down to your crack, the feeling has you shivering in anticipation, before long she stops and you feel her massive 16 inch cock flop onto your back, it's weight lays dead on your back, you can feel the heat of her cock, as it throbs eager to destroy you. She then begins to move her cock back and forth on your back and down the crack of your ass, sawing through your cheeks with her massive fuck stick. Before long her precum is pouring out of her dick onto your ass flowing down into your crack like hot wax. Her dick then slides all the way down your back and through your cheeks running down your asshole until she puts her cock head directly toward your asshole.

"Are you ready dear, because here I come!"
