Amy POV

Today is our anniversary and I want to do something special. We've been experimenting in the bedroom. And we've talked about anal sex. I want to try it tonight. I've already waxed and got an enema. I practiced anal when I masturbate just to see what it'll feel like. I'm going to discuss it with him after our anniversary dinner. The clock reads 6:30 pm, it's almost time to leave for dinner.

I'm dressed in a modest yet form-fitting black lace cocktail dress and stilettos. My hair is in big bouncy curls, I decided to ditch my glasses for contacts tonight and my makeup is done to perfection. I walk to the living room and I see that Sheldon is standing in front of the mirror fixing his tie and putting on his watch. He grew out his hair and it slicked back. He is wearing a suit that fits him to a T. He turns around and sees me and stares in awe. "Don't you look ravishing tonight.", Sheldon said as he strides towards me. I giggle as he gives a kiss on the cheek. "So do you.", I said. "Time to go. Our reservations are at 7:15.", he said as he led me to the door. We grabbed our coats.

We arrived at a french restaurant that we go to from time to time. " Ah, the Coopers your table is ready, right this way.", the Maitres d said.

We arrived back home from our anniversary dinner. I was excited yet nervous to ask him to have anal sex tonight. We've talked about it before and seemed open to it at the time. I hope he hasn't changed his mind about it.

"Sheldon, can we talk?", I ask. He walks over to the couch and sits next to me with a concerned expression. " It's nothing bad.", I tell him. He relaxes, nods at me to continue. "We've been experimenting in the bedroom and I want to try something new tonight.", I say in the most steady tone I could muster up. " I want to try anal tonight. It's something we've talked about. I've already made the necessary prep. I'm ready." " Are you?, I ask. Sheldon has a surprised look on his face, then smooths it over with a serious look. " I'm opened to trying anal tonight. I've done some research after our first talk. I've all of the protection we'll need", he said. It was sexy how prepared he was. "If we're going to do this you have to listen and do as I say. I want to not only make this amazing for me, but I also want to make this amazing for you.", the physicists said in a stern tone. "I will. I promise.", I said.

The lights are dimmed and soft music is playing in the background.

I'm on my back on the bed, with one of my legs over Sheldon's shoulder. I'm withering and moaning as he puts a lubed gloved fourth finger up my anus. "Please baby, please fuck me", I beg. "I don't know. I like watching you wither on my fingers.", the physicist says as he pushes his gloved fingers in and out. "Please, I'm ready for you.", I said. "Alright princess, anything for you,", he said as he thrust his fingers in one last time before pulling out.

He discards his gloves and starts putting on a condom. He puts an excessive amount of lube on his condom dick, you can never have too much. Sheldon grabs Amy's legs and puts them over his shoulder. He slowly pushed into her anus. Amy lets out a strained moan from the pain. He keeps going until he is balls deep and waits for her to adjust to his size.

"You can move now.", I moaned out in pleasure. He starts to slowly thrust into my anus. We built up a slow rhythm. After a while, I wanted him to go faster. "Please go faster," I ask him. Sheldon starts speeding up and his once quiet groans become louder. He thrusts harder. "You like me pounding your asshole, princess?", my husband asks me. "Yes, I fucking love it, baby!". I exclaim. His trusts become sloppy, a sign that he's close. " I'm going to cum in your asshole, do you want that, princess?", he asks. "Yes, fucking cum in my asshole, baby!", I shout. Sheldon groans and curses as he fills his wife's asshole with his cum. The feeling of her husband cumming up her ass made her squirt.

Sheldon and I lie like this for a bit. Just basking in the glow of orgasms. He pulls out of my anus. Just the feeling of him pulling out makes me horny again and I see it makes him hard again. The knowledge that we did something as taboo as anal just turns us on. He takes off the condom and wipes off his dick and my vagina. He spread my pussy wide and plugged in. We both moan. He goes fast and hard out the gate. The sound of my pussy being pounded is echoing around the room. I hadn't yet recovered from my first orgasm so I came again. He goes for what felt like hours, he has good stamina. He cums in my pussy again, and I cum for a third time tonight. I don't know what it is, just the feeling and watching of him cumming inside me just always set me off.

He rolled off me to the side. We were both trying to catch our breath. Sheldon slid his hand down to my pussy and felt his cum leaking out of me. He brings his hand to his mouth and tastes himself along with my juices. He moans and shivers at the taste. The physicist lowers himself down to my pussy and starts licking and sucking. I moaned and the licking and sucking got more intense. After he's done sucking all of his cum out of me, he comes up to my mouth to share his cum with me.

He collapsed back onto his side of the bed. He kisses my forehead and says, " Tonight was amazing, it's the best sex we've ever had.". "Yeah, it is.", I said smiling. We both said goodnight and passed out from exhaustion.
