First time pegged

“Fuuuuuuck!” I moan through gritted teeth as the head of the strap on passes through my virgin anus. I stop moving, trying to relax and gather myself as these strong sensations scream to be felt. “You are such a good boy” she moans, “Relax and take your time to adjust to the feelings.”
I breathe, trying to relax myself and look down at her gorgeous face with her cheeky grin beaming back at me. I slowly lower myself further down the dildo until I am sitting on her pelvis. I stop to feel these new sensations; full, stretched and dirty. “Oh yeah babyboy, you have my full 7 inches inside you, how do you feel?” She asked me. “Incredibly turned on” I reply, as I look down to my cock which is harder than it has ever been.
I put my weight on my knees and slowly raise and lower myself, feeling the plastic cock sliding in and out of my rapidly relaxing hole. The feelings of being full, the feelings of the head rubbing my prostate every time I lowered myself were mind-altering. My cock was positively drooling pre-cum, running down my shaft and pooling on the harness of her strap on. We lock eyes and I watch her watching me being her personal little anal whore.
She tells me to sit up on my knees, as she wants to fuck me now. I sit up, and she grips my thighs, slowly lifting her hips of the bed to slam her rubber shaft into my tight, lubed up hole. Faster and faster she goes and I hear my cock slapping on her belly. I sense the familiar feelings of getting ready to cum. “That’s my filthy little slut, I want to watch you cum as I fuck you senseless” she commands me.
I start to moan, and it turns into a roar as I explode, hot spurts of my cum showering her tits. Stray splashes land on her face, her mouth open to catch whatever she can on her tongue. “Good boy” she coaxes me as wave after wave of ecstasy flood through my whole body. I’ve never cum this hard, or this much in my life! I lower myself to sit in her, the last drops of cum dribble down the shaft of my still hard cock. We kiss passionately while her rubber cock is still inside me. “I’m proud of you” she says, and slowly pulls the dildo out of me…
