"I am going to fuck you in the ass Millie"

I say. I take her by the shoulders and gently help her to her feet, then say: "Bend over that sofa."

Millie gives me a nervous look, but does as I have told her. She walks over to the sofa, kneels in front of it, then leans forward so that her ass is protruding out. She lifts up her dress over her hip, revealing that she is wearing white stockings under her wedding dress, and a very thin white g-string.

I kneel down behind Millie, and slide her g-string aside with my finger, revealing her light brown coloured, and very tight and inviting looking ass hole. I lean forward, and spit some saliva on her ass hole, rub it around with my finger, then spit on her ass hole again. This time I push my finger into her ass to the knuckle, and she feels very tight.

However, I decide that this minimal preparation is enough, so I slide my finger out of her ass, shift my body into a good angle, grab the root of my dick with one hand, and push the head against Millie's ass. This is proving more difficult than I anticipated, since the combination of Millie being nervous and the minimum lubrication means I can't get my dick into her ass.

I stop what I am doing, spit on my fingers and rub some saliva onto the head of my dick. I again place my dick against the entrance to Millie's ass, but I am still struggling to get it in. I move back a bit, then I thrust forward with my hips, and Millie's sphincter gives way and I push into her very tight ass.

Feeling my dick enter her ass, Millie's face turns red and she starts breathing very rapidly. She is a real trooper, I think to myself, this is a tough anal session I am making her do. I am sliding only the top part in and out of Millie's ass, giving her a chance to adjust to the intruder in her ass, but then suddenly I thrust forward and push my dick as far into her ass as it can do.

Millie cries out from the shock of the sudden very deep penetration of her ass, so I give her a moment to adjust to having her ass fully impaled by my dick. Then I very slowly start pushing in and out of Millie's ass.

I keep going for a while, and Millie's body starts to relax, she is now more used to the feeling. I am still pushing in and out of her ass at a very slow pace, but I feel her body moving weirdly, and I realise she is sobbing.

Feeling sorry for her, I slide my dick out of her ass, and ask:

"What is wrong?"

Millie replies: "Don't stop, put it back in."

I push my dick against Millie's ass, sliding in much easier this time than the first time, and I resume gently fucking her in the ass.

Millie looks over her shoulder at me and says:

"Sorry Matt, but this is all very emotional for me."

Then continues:

"The first time I got fucked in the ass was on my wedding night, wearing this exact dress, and bent over a sofa almost exactly like this."

I lean forward and kiss her, still sliding in and out of her ass, and say:

"I understand."

She replies: "I want to feel your dick in my ass, this is really special to me."

I gently pick up the pace I am ass fucking her, and Millie says:

"That's it, fuck me in the ass."

I pick up the pace even more, and Millie says calmly:

"I want to feel your cum in my ass."

I start fucking her even harder, then I hear from the door:

"Mom, what the hell?!"

I look over and see a brunette girl standing in the doorway.

"Dad has barely finished moving out, you are not finished divorcing, and I find you here on the floor in your wedding dress being fucked in the ass?!"

I freeze into position, but Millie looks back at me and shouts:

"Keep going! Don't mind her!"

I resume fucking Millie in the ass, but at a pretty slow pace, looking at the girl standing in the doorway feeling a bit embarrassed. Millie notices that I have slowed down, so starts pushing her butt backwards at a high pace, shouting:

"Cum in my ass!"

Hearing her shout this, combined with the tight grip of her ass on my cock brings me over the edge and I cum in Millie's ass.

Millie feels my load shooting into her ass, so to enhance my pleasure she starts squeezing her ass, milking my cock of the last drop of cum. All through this, the young woman who I realise must be Millie's 19 year old daughter just stares at us. Her eyes are shooting daggers at Millie, she shouts: "You are just a butt slut mom!" Then storms away.

Millie jumps up at this, my cock pops out of her ass and she runs after Ashley, shouting: "Don't you dare call me a butt slut!"

I hear them shouting at each other as they are running upstairs.
