You were standing behind Rainbow Dash, admiring the view. Her tight, blue pegasus ass called to you, teasing you with its imagery.

“Damn… that looks so fuckin’ good,” you mumble under your breath, unable to take your eyes off her rump. Every slight movement of hers made your cock throb with anticipation. Your hand traces down your pants, gripping your massive erection tightly.

Rainbow Dash, completely oblivious to your wandering gaze, is distracted by feeding her pet turtle, Tank.

“Alright, buddy, open wide!” she said, trying to get Tank to eat his lunch. She places the lettuce in front of his face, holding it slightly above his head. Meanwhile, you can no longer resist the temptation. Within seconds, you close the gap between yourself and the athletic mare.

Using your arm’s reach, you pull her hindquarters closer to you with one swoop. Before she can react, you immediately shove your pulsing cock into her tight marehood. Rainbow Dash gasps and freezes mid-sentence, her eyes wide with shock.

“Wha-what the buck?!” she exclaims, as you start thrusting into her, feeling her walls clamp down around your manhood. Even though your presence comes as a surprise, you can feel her body react, growing wet and warm around you, responding to you.

“You bucking perv!” she yells, half cursing you and half moaning from the pleasure. “You couldn’t wait, could you?!”

Rainbow Dash was never the shy type. Even in this compromising position, she felt free to express herself. “We were supposed to be taking care of Tank, remember? …Oh, Celestia!”

The pegasus resumes feeding her pet turtle despite the fact that you’re now pounding into her with wild abandon. The lewd sound of skin slapping against her beautiful blue ass echoes through the room, punctuated by her breathy moans.

“Well, at least do it right!” she growls, bracing herself against the wall to hold herself steady.

You smirk and start pumping your cock in and out of her marehood even harder. You could feel your primal urges taking over. The tight grip of Rainbow Dash’s walls around you is too good to resist, and you feel the tension building in your balls.

Rainbow Dash, meanwhile, begins to lose her grip on the turtle food while trying to maintain her composure as her squeals increase in volume. “Buck, like that!” she bites her lip, her voice full of lust.

As you push Rainbow Dash closer and closer to the edge, her wings involuntarily spread wide. You reach out and grab one of them, feeling the silky soft feathers beneath your fingers, and gently tug it.

Your powerful thrusts and Rainbow Dash’s moans of pleasure reach a fever pitch together. Finally, your grip on her wing is the last straw. Rainbow Dash screams out in ecstasy while Tank continues eating his lunch, blissfully unaware of the spectacle taking place behind him.

As you continue pounding her senseless, you and Rainbow Dash both come crashing down from your climaxes, panting and sweaty, with the satisfaction of sharing this intimate experience lingering in the air. But in your heart, you know, you’re left yearning for more…

And the knowledge that you took Rainbow Dash from behind so eagerly, you wonder, will you be able to resist your desires next time?
