Bday Gift

My bday was coming up, and my wife asked if there was a bedroom bday wish this year. I told her I wasn't sure yet. I did have something in mind though. For a long time now I've wanted her to peg me. I even got a harness with a strapon. She knows I've had this fantasy. But it's a little embarrassing to talk about. It's the type of fantasy I wish she would do with little communication. While my wife is adventurous, making the 1st move, or initiating new sex is not really in her wheel house. So I knew if I really wanted this, I'd have to ask. I found a small clip on Twitter of a cute couple pegging. She gets on top of her man and slowly slides it in, and gently starts to fuck him. I decide I'm going to send her the link and tell her this is what I'd like. I nervously hit send on messenger. She sees the message, and I nervously wait for a reply. The only thing she does is heart emoji the video. I feel relived and excited, and a little scared.
On the night of bday I lay out the harness for her, and send her to the bedroom 1st so she can put it on. I go up and join her, she's laying on the bed completely exposed, and to my suprise she's removed the small starter dildo and replaced it with my (what I thought secret) realistic black cock dildo. She wraps her hand around it, and is stroking it. She nervously says to me "Is this the one you really want baby?" I smile and look her over, she looks so incredible, I nod my head yes, and join her in our bed. We start to kiss and I grab her cock with my hand, I love how it feels. She tells me she wants to see me suck on it. I'm happy to oblige. I finger her wet pussy while I suck on her cock, I'm rock hard, she's moaning and getting wetter by the second. It's time. I get the lube and stroke it all over her black cock, then I lay down on my stomach so she can fuck me. She gets behind me puts lube in her hand, I feel her hand rubbing the lube between my butt, then she slides her middle finger right in. I go limp and let out a relaxed moan. She starts to finger me, and embarrassment or feelings of doubt are washed away by the pleasure I'm feeling. I pull my ass apart, the words "fill me up, and fuck me baby, please!" Escape from my mouth. She obliges. Slowly I feel my ass stretch, it hurts soooo gooood. She lays on top of me, I can feel her weight pressing against me. I feel so submissive. I'm moaning like a girl getting fucked, my wife loves it when I moan for her, so she keeps rocking her hips and fucking me. She's kissing the side of my face and back while she does this. It's amazing. I decide I want to get on top, so we switch positions. She lays on her back and I startle her body. It feels very different to have my wife between my legs instead of me between hers. I like how it makes me feel. A little effeminate. It feels good to slide back onto her cock. I start stroking my dick while I ride her. It dosen't take long and I'm ready. I cum all over her chest and belly. She makes a sound that reads pleasantly suprised. It was so much fun. I ate her pussy out over and over to show her my appreciation. It was so much fun.
