Futashy's Surprise (Just for fun)

You sigh as you sink into the soft cushioning of the massage bed, already feeling nice and loose from the warm scented bath you'd been through just beforehand. You had to hand it to Rarity; she was a class act, giving you an all-expenses paid spa trip as a gift like this. For a while you'd been worried she'd hold a grudge from that huge prank you, Dash, and Pinkie pulled on her a couple weeks ago, but it seems the Element of Generosity was living up to her title.

You hear the door open and close behind you, and the faint hoofsteps of a pony walking up to you. Too blissed out to even bother turning around to face her, you close your eyes and smile.

“Um, hello. It's time for your deep tissue massage.” You frown a little bit as you feel the pony actually leap up onto the massage bed and straddle you, one forehoof falling to either side of your head. You'd heard of unconventional massages like this, where the masseuse would actually do things like very carefully step on your pressure points, but you never knew the spa here in Ponyville offered such services. “Please try to relax...”

Shrugging inwardly, you do as your told, going totally limp on the bed underneath the pony. You should probably thank her. Come to think of it, was that Lotus or Aloe behind you?

Just then, you you notice something you probably should have earlier: the hooves to either side of your head are butter-yellow.

“And,  uh... Rarity told me to say something...” You feel an enormous, warm, fully erect futanari cock probe your ass, positioning itself at your entrance. Still somewhat stunned, you react too late, as Fluttershy finds what she's looking for and presses her cockhead firmly against your pucker, bracing herself. “Umm... 'surprise buttsex.'”

She thrusts.
