Mint on a Leash

It is a shock to both of them, the first penetration, and only at twenty two for both of them. Both exhale sharply, but only the dom keeps his cool and continues to thrust, while the sub moans and quivers under the loving penetration of her master. Colgate's pussy tightly squeezes her boyfriend's cock, like squeezing the last drops of salad dressing from a plastic bottle. Patient's lower head widens the walls of his loving sub as his heart quickens its pace, making him breathe quicker and sweat more. The pulling and pushing force of Colgate's wet, hot vagina forces Patient to almost black out for a while, making sure that he doesn't get too excited and finish too early.

To Colgate, this was a dream come true. She groaned and panted with each thrust of her dom. The collar around her neck felt tighter, choking her and giving her more excitement. Her leg-socks were soaked with sweat and love juices. The constant motion of her lover's penis rubbing on her clitoris on its way in and out kept the sensations higher than standard penetration. She lovingly engulfed her boyfriend's stallionhood deeper and deeper into her hole until it was at his hilt, giving his whole rod pleasure that he has never felt before. To Colgate, this was perfect.

Patient, who had been mostly silent throughout the penetration, began to grunt and sweat more, feeling that precum might be heading on its way soon. He pulls out, not wanting to get precum or any sort of cum anywhere near his girlfriend's pussy. His penis is soaked in love juices and Colgate's pussy lies slightly agape and letting loose more drops of excitement.

"You wanna try the other hole?" Patient asks, biding his time until the precum sensation dies down.

A short pause as the sub thought of her options, anal or more whipping?

"Yes master, but could you smack me with your riding crop while you do it?" Colgate asks, hopeful that things would turn out her way.

"Of course, slave." Patient grins, grabbing the riding crop and adjusting his penis.

Patient's cock now rests at the backdoor, the tightest hole of any mare. He waits for a few seconds, then rests the end of the riding crop gently on the hourlgass.

"Please, master, fuck me make me your little bitch!" Colgate spouts without command, a tear of ecstasy rolling down her rosy, warm cheek.

Patient takes that as his cue.

He takes the plunge, pushing it in all the way to the hilt. Colgate's eyes shoot wide open and her pupils contract quickly as she gives a surprised yell, which quickly regresses to a loving moan of pleasure. The g-spot inside of her colon is on fire; Patient's cock is the only thing that can put it out. Her ridiculously tight anus squeezes, almost chokes her dom's dick as it pushes in and pulls out like a rhythm.

Patient, on the other hoof, is beginning to shiver and shake. He knows that sooner or later, he's gonna cum; and it's gonna be messy. He just presses on, continuing to mercilessly fuck his girlfriend with every fiber in his penis and hips. Her tight asshole completely engulfs his cock, almost sucking it in like a whirlpool. The aching in his balls let him know that the time was near, that he couldn't stop now.

The dom's hips and balls smack gently against the plot of the sub, who continues to drag her hooves across the sheets and groan louder as her g-spot becomes more and more pleasured. Colgate's stomach is filled with various butterflies of every shape and color, each one tickling away at her insides. She's in heaven; bound to a bed, being fucked in her tightest hole, clad in lingerie, nothing could be more perfect for her...except if she were to be spanked.

Almost as if Patient could read her mind, he smacked the riding crop down onto her thigh, even harder than the foreplay smacks. These smacks made audible cracks, and caused the gorgeous, sexy moans from the sub to be broken by sudden pained yelps as more love juices squirt from her non-virgin pussy.

Both minds are engulfed in pure pleasure and love as they both close their eyes and treasure in this beautiful moment. Colgate raises her plot up a few more centimeters as she feels Patient's thrusts grow more and more violent, his smacks with the riding crop become more and more frequent. Patient lets out a groan of his own as he nears climax, the feeling in his balls telling him that it's time. He tries his best not to release, but the feeling is just too strong...

Colgate seizes and shudders as a river of hot, sticky cum rushes into her colon from the dominating stallion behind her. The one final notice before the eventual climax was a ridiculously hard slap with the crop on her lower back, which caused her to yell with pleasure-filled pain. Patient keeps his eyes closed throughout the whole seeding of his girlfriend, letting himself be overtaken by the sensation and satisfaction.

At least ten seconds go by before Patient collapses onto his lover's plot, which lowers back down to the bed, soaking it with the remnants of vaginal secretions. It's done. He successfully fucked a mare for the first time in his life. He climbs off of Colgate and lies down next to her on the bed, untying the leash and unclipping it from her collar. Colgate sighs and shifts her body over towards her boyfriend and snuggles up next to him. She folds up the leash and places it on the night-stand next to the bed.

"I love you so much." She whispers as she hugs Patient tightly and pecks him on the lips.

"I love you too, babe." He sighs, smiling and kissing her on the forehead.
