I've been asking my wife (31) to peg me (30) for a while now. She has always said no, until a few weeks ago. She said she would consider it. The next day I bought one online. I figured if she decided she still didnt want to, one of my other partners (we are poly and open) would use it with me. 

A week later we get home from the bar feeling pretty horny. We're in bed, I'm using her favorite vibrator on her and licking her clit, getting her all warmed up and wet. 
"I want you to Fuck my ass tonight." I whispered in her ear.
"Only if You Fuck me first." She said.
I was ecstatic! I pulled out a butt plug and asked her to put it in me. I got on my knees and felt her slowly lube up my ass and slide the plug in. She gave it a nice little wiggle once it was in, making me moan.

She got on her hands and knees, she loves taking it from behind.
"Now fuck me hard!" She said. 
I slid my hard cock in her and started fucking her. We talked about how much we wanted to Fuck this guy we know while I pounded her. I pulled out and shot my load on her ass.
"Clean it up." She demanded.
I licked all my cum off her ass cheek and from her crack as I always do.

I pulled out the strap on. It's actually strapless, the kind that slide in the vagina and has a dildo attached. She laid down, she had already told me earlier that if we were to use it I'd have to ride her. I pulled out my butt plug and straddled her. I grabbed hold of her cock and guided it in my ass. It felt so amazing, buzzing away inside of the both of us. We kissed while I moved up and down on her cock. She moaned her end moved within her.
"Will you Fuck me from behind?" I asked. 
She agreed.

"Lay down flat and put your legs together." She ordered. I complied. I felt her get on top of me. She rubbed the strap on against my ass and put it in me. I felt songood I couldn't stop myself from moaning. She laid on me, fucking me. I felt like hours of pure pleasure. She slid out of me.
"That's it for tonight." She said. 
We talked a bit about the night, she enjoyed it. She told me that if I'm good I can have it again. I can't wait.
