Anal

Once you decide your cock is well lubricated enough, you have her get on all fours on the couch in her office and reach back to spread her ass cheeks apart. You don't waste any time before you step up behind her and start shoving your cock into her asshole.

"Ohhhh fuck! It isn't going to fit!" She squeals out.

"Relax and it'll fit just fine." You say.

Sofia slows her breathing and you notice her tight anal sphincter relax. With this window of opportunity you pop the tip in before sliding half your length inside of her backdoor. It slides in surprisingly smooth.

"Hijo de puta!" She exclaims in Spanish as you bury your cock deep in her back door.

"It needs more lube." She pleads.

You don't mind obliging her considering it'll make it easier to fuck her harder, and so you grab some lube from one of her desk drawers which are fully equipped with whatever sex toys her superiors may need from whips and spankers to handheld vibrators. Once you use the lube generously on her asshole you're able to slide in and out much more easily.

After a good while of building up your pace, Sofia seems to be adapting to handle anal much better. She even seems to be starting to enjoy it, using her hips to back up into your cock as you thrust, or perhaps she's just trying to make you finish faster so this whole ordeal will be over with faster.

You continue fucking her ass for almost 20 minutes, gradually building up her anal tolerance. By the time you feel yourself getting close, Sofia's taking it like a pro and moaning like one too. At this point you have her on her back on top of you and you're really going to town on her back door.

"Dios mio! Fuck me! Fuck my ass!" She squeals.

You feel as though she may even be approaching an orgasm and kindly start rubbing her clit as you pound her asshole. Moments later and she's spraying squirt juice all over herself.

"Ay! Ay! Ay! Thank you sir!" She squeals as you make her climax.

You're not done with her yet though and after giving her a brief moment to recover from her orgasm get right back to fucking her. When you're finally ready to finish, you get her down on her knees and cum in her mouth. Since that first night that you had the men of the office run a train on her, Sofia's given into her deep-seated desire for cum and shows no shame in savouring every drop of seed you release into her mouth.
