As the black stallion got down from Paul's back he retreated into his own stall while Paul and Sarah went out into the field and fell asleep while standing.
In the mourning Paul was very disoriented and didn't remember much about what happened to him last night. He remembered facing the black stallion and being naked however it was all a blur.
As Sarah woke up faster she went beind him and gave him a playful tongue on his moist lips.
His memories came back to him in full force as he opened up his eyes to his new life on all fours.
Morning Paul! said Sarah, hope you had a refreshing night's sleep. I know I had after witnessing what happened to you yesterday.
I'm gled you enjoyed the show Sarah. I can assure you that standing on all fours and taking it is not as easy as it sounds.
That stallion fucked my pussy so hard that I don't even have memories of what's like to have a cock anymore.
Serves you right, you asked him to do this to you, practically begged. said Sarah as her member was sliding out of its sheath and swinging below her.
Wow Sarah, how far our relationship has changed!
For the better Paul! said Sarah.
Our relationship is finally perfect now that you are no longer in control of any of it!
Now we can have sex for how long I want, how I want and where I want, Paul.
And the only thing you can do now is stand there on all fours and have your puffy lips swell in anticipation of what I can do to you.
Paul's ears lowered level with his head as he looked at his girlfriend,his puffy lips indeed swelling.
I wanted this as well, it wasn't just for you, you know!
Oh I know Paul,you were willing to become a horse and a mare before you were aware that I was one too.
You dreamed of this, having stallions pin you down and fuck the humanity and man out of you.
Whatever you say Sarah, the reality is that now I'm a filly and you will have to come to terms with that, because it seams to me you are living in the past!
Oh, it's not me who has to come to terms with the fact that now any stallion can stick its cock in between your legs and now you are designed to take it, want a demonstration? said Sarah with her member increasingly hard in between her legs.
As she said that 3 other stallions made their way into the pasture and were circling them with their member's just as hard as Sarah's.
Care to take your pick Paul?
Paul was looking at all of them with slight fear like he was being attacked or hunted which he was.
Sarah let's get out of here and do it in a place a bit more private!
Why Paul, this just perfect, now we have audience. As she said that she manuvered herself behind him and jumped on Paul back. A few pumps later she penetrated his folds and started pumping into him with unrelentlessness giving him 2 orgasms before she spilled her load into him while he closed his eyes and accepted fully his new role in their relationship.
Immagine what they'll do to you once I dismount you. Said Sarah still on his back without thrusting.
They haven't spilled their load in over 2 weeks and you seem to be a good candidate. As she dismounted off of his back almost instantly another stallion jumped on the mare's back while Sarah went to his snout with her cum coated member swinging in between her legs on full display and said:
I told you I would do this to you 3 times a day, however I didn't say anything about my fellow stallions getting turns while I rest and produce some more semen for your puffy lips.
Welcome to your new life Paul!
As she said this the second stallion found its mark at the back of the mare as she steadied herself for round 2 out of 4.
