A strap on dildo

"What is that?" You ask, slightly afraid.

"It's a strap on." She tells you. She shows you the black dildo, which is at least ten inches long and about three inches in girth.

"What's a strap on?" You ask. Margery smiles at your innocence.

"Sweet King Tommen. Why don't I show you?" She suggests. You frown, as she staps the dildo around her Waist, so that it looks as though she has a cock, and it's almost three times the size of your own natural cock.

"Margery..." You swallow hard.

"Turn around." Margery interrupts you. You do as she says, scared that she'll punish you again if you disobey.

You lie on your front, and Margery pulls your hips so that your ass is up in the air. She spreads your cheeks, and presses the tip of the dildo against your asshole.

"Hmm. Too tight." She says. You're confused, but soon gasp as you feel her licking your asshole, lubricating it with her saliva, before she pushes two fingers in to stretch your hole out. Then three fingers. Then four.

"Margery that hurts!" You tell her, as she stretches your hole with her fingers.

"It'll hurt a lot more if you resist." Margery tells you. "Just relax and it won't be as painful." You do your best to relax as she instructed, and let her fingers explore your ass, until she pulls them out.

"That should be enough." She tells you, before guiding the strap on to your ass. You gasped as she slowly pushes the first few inches in, your eyes watering by the time it's halfway in.

"Ow!" You wince, as she pushes the rest of the dildo into your ass, almost completely dry, so that the ten inches of the fake cock were buried in your ass. Margery smiled, as she began fucking you in the ass with the dildo.

After a few minutes you're crying, **** to beg her to stop, but remain silent, save for your sobs. Margery grunts as she fucks your ass bloody, slamming into your ass with all her **** with each thrust, brutally fucking you.

"I've got to say, you're lasting longer than I thought you would." She tells you in between thrusts. " I thought you'd be begging me to stop by now."

You're somewhat comforted by this, knowing you didn't disappoint her, but the pain and humiliation is still strong.

"You know, Renly didn't mind this when I was married to him." Margery continues. "Although, Come to think of it, I think he preferred my brother!" She laughs, as she fucks your ass bloody.

Margery continues this for almost an hour, before she's seemingly exhausted, and lays down beside you.

"You're so tight!" She tells you, with a playful kiss. "But don't worry, after a few weeks, we'll soon change that." She says, as she takes off the strap on and puts it away.

"Now, before we go to sleep, I want you to..."
