Get Callista ready with your tongue

Maybe this isn't exactly what Callista wanted, but you can't wait to worship her thick ass. You kneel well behind her and lean in, licking her butthole lightly. She shudders and moans in pleasure. "Whoah," she says. "That wasn't exactly what I had in mind, but I'll take it."

You softly, sensually lick and lap around her crack, enjoying the taste of her skin. But you got down here in the first place to get her ready. So you kiss her anus directly and push your tongue against her. She freezes, hoping you'll go farther, and after a couple of tries, you manage to push your tongue into her. Immediately, she starts pushing back against you uncontrollably, growling wordlessly in delight. You put your arms around her thighs from behind, and one of your hands brushes something hard. Oh, right, that. Still eating her delicious ass, you wrap a fist around her hardon, stroking her almost imperceptibly and reveling in how hard you've made her. She tries to thrust into your hand, but you prevent her. Once you've had your fill of her butthole, you decide to move on to the main event.
