Have her get on her hands and knees

"I've got to have you on your hands and knees next." you told her when the two of you reached her bed. "I've been staring at that ass of yours for years, but it's always been covered up in bikini bottoms or your tight jeans. There's no way I'm letting today end without seeing you bent over, naked, sticking that incredible ass up in the air."

She giggled at your statement. "You're not the first guy to want me like that." she revealed to you, then climbed onto the bed with a bright, toothy smile and reached back to spread her ass cheeks and pussy lips apart. "Is this what you had in mind?" she asked giving you a fully unobstructed view of her most intimate parts.

"Oh my god, that's perfect." you said kneeling behind her, referencing not only her position, but the site she gave you as well. You began planting kisses on and around her plump, sexy ass cheeks first before making your way back to her pussy and it wasn't long before you were working her with your tongue once again. This time you started off a little slower, alternating between sucking her labia into your mouth and slipping and twirling your tongue inside them, making Kelly moan out in pleasure.

"Your asshole looks sooo good from here. Do you like having that licked too?" you asked during a small pause in your oral attention, knowing not all women enjoy having it played with.

"I... I don't know." she replied, almost sounding a little embarrassed by the question. "No one has ever done that to me before."

"You're kidding me! A freaky little slut like you hasn't had her ass rimmed before!?" you asked truly in shock, then decided to gauge her reaction by rubbing your nose into her brown, puckered hole as you dove back in to get another taste of her pussy.

She let out a small gasp of surprise at the sensation. "Ooh! ... Uhh, no, I've only had it fingered when I was fucking sometimes. Why? Do you want to do that to me?" she asked, sounding intrigued by the idea.

"Oh Kelly, I'd love to be the first guy to tongue your hot, little asshole." you answered hungrily. "I guess we're gonna find out right now if you like it or not. Spread that ass apart for me again and you can let me know if you enjoy it. I'll stop if you don't like it, but I doubt that'll be the case." Having your nose pressed into her ass before, you didn't pick up any foul odor so you felt safe with what you were about to do, and started off licking around the rim of her sphincter. Hearing, what sounded like a faint moan and no objections from Kelly, you then began probing her hole with the tip of your tongue, pushing just inside her while you began rubbing her clit between your thumb and finger.

"Oh wow David! Oh fuck that feels good! It's making me tingle in a whole new way! I definitely don't want you to stop!" she told you with surprise in her voice and started moaning much louder in response to the new sensation.

Slipping your fingers back inside her pussy, you curled them down to stimulate her g-spot while you started to tongue-fuck her ass, working your way deeper as Kelly's outer ring began to relax, while getting more into the task and moaning out yourself as you saw the effect it was having on her.

Picking up on your enthusiasm, Kelly resumed her dirty talking ways, encouraging you even more. "Ooh, you're getting turned on eating my ass, aren't you you little pervert? You like having your face buried in my nasty, slutty ass, don't you? Well keep doing it! I fucking love it too! Fuck it feels so good!" she told you as she pulled her ass further apart to give you better access.

You now had a new goal that you set for yourself, and that was to make Kelly cum from having her salad tossed and you began doubling your efforts on her two holes. The profanity-laced yelling that started to escape her mouth let you know she was responding to what you were doing and her hand soon left her ass so that she could claw it into her sheets. Kelly's body must have already been on edge from the multiple orgasms she'd had up to this point, because before you knew it, she was burying her face into the sheets to muffle her screams and your hand was suddenly covered with her juices that began flowing out of her pussy. Cumming from this new approach must have been too much for Kelly to handle because before she seemed to be finished, she pulled away from you and collapsed onto the bed, body shaking as the last effects of her orgasm trailed off.

After taking a moment to recover, Kelly rolled slightly onto her side to better look over her shoulder at you, a combined look of awe, and satisfaction on her face. "I don't know how to explain that orgasm. It was amazing, but it felt different than any I've had before. I guess it's safe to say I do like having my ass rimmed, but my pussy feels so empty and neglected right now. Please tell me you're ready to go again?" she asked you. "Your fingers were good, but I need your big, hard cock filling me back up, bottoming out on me, and making me cum over and over again." she said while shaking her ass side to side for you.
