Assess Anna's ass

Erica was probably right about at least one thing: Anna's petite backside would be hiding an incredibly tight arse-hole. Smiling somewhat cruelly, you rise from your seat and make your way to Erica's bedroom, discarding your unneeded underwear in the process. You open the door and walk in without bothering to knock.

Erica looks up from the DVD player and smiles as she eyes your free erection. "Hi cuz, you here for anything in particular?"

"Don't mind me, I'm just here to examine Anna's delightful rear."

Anna, whom was lying on her stomach on Erica's bed, flexed her lower back to raise her ass up into the air. "Go right ahead, John," she approves with a flirtatious smirk. "I hope you like it."

Sitting next to Anna on the bed, you lay your hands on the proffered asset. A gentle squeeze reveals tight and surprisingly strong muscles lying just under the skin. You rub your hands across the smooth flesh before running a finger between the cheeks and gently rubbing her asshole, eliciting an appreciative hum.

"I think she likes that," Erica observes as she joins the two of you on the bed, leaning back against the headboard.

"Of course," you respond, seizing an opportunity to conduct an experiment into whether your abilities can re-write people's history. "Anal play is the only way Anna can get off...isn't it, Anna?"

"Uh-huh," Anna confirms with a moan as you slide a finger into her arse, "but how did you know that?"

You smile with amusement, "I didn't."

"Oh, you jerk!" Anna laughs, pushing her butt up harder into your hand. "So are you going to fuck me, or just sit there and tease me all afternoon?"

While the thought of some extended teasing is appealing, your downstairs friend threatens to veto any such actions. You briefly ponder this dilemma: should you tease Anna some more, likely driving her crazy? Or should you take full advantage of your newly minted anal addict? Ah, decisions...
