If she takes you in her ass, you'll back her friends promotion

"Vivienne, I will personally back your friend for a promotion, but first you must take my cock in your ass and ride it." you say stoically.

Vivienne is completely unfazed by this and nods. "Very well my dear. It is good to know that I can count on you." She says as she undoes her pants and pulls them down her long legs.

Now bottomless she waltz over to you and turns away, showing her round, voluptuous ass to you before she bends over. Looking between her legs she lines up her hips with your cock and lowers herself so that the tip presses against the entrance to her ass. Slowly but surely she presses down and you begin to fill her tight ass with your hard cock.

You hear a slight whimper from Vivienne as you go deeper, almost half way and then a loud yelp when you grab her hips and enter her completely. The big butted mage moans as she gets used to your massive cock in her ass and begins to bounce, riding your cock like she would a mount.

You sit back and watch her juicy cheeks jiggle and her hole stretch to accommodate your size with a grin. as does Morrigan, happy to see Vivienne get roughly stretched for once. You don't notice this at first, or else you'd have Morrigan go around and eat Vivienne out while you fucked her ass, so you simply enjoy invading the magical adviser's ass.

Vivienne's cheeks bounces wonderfully, her asshole now welcomes you with no resistance so you hold on to the horns on her hat and thrust into her as while she bounces on your cock. Her usually composed demeanor has given way to a taste of her slutty side as she wails for all to hear.

You blow a huge amount of cum into her ass and she slows to a stop as you pump her ass full. She falls forward off your cum glazed cock and drops to her knees showing your seed leaking from her gaping ass. You give her ass a mighty slap and watch the cheeks jiggle once more and Morrigan dutifully tends to you cock to clean it off.

"I'll have Josephine work on the documents and your friend will be prompted in no time." You tell Vivienne. Vivienne turns, but seeing as Morrigan has your cock halfway down her throat, Vivienne kisses your balls as she would your cock head.

"Thank you again Darling. I'm so glad you could help in this endeavor." she says, standing and waddling away with her pants in her hands, giving you the incredible view of her ass as she leaves.
