Finger her holes

You nudge her thigh outwards with the back of one hand and say, "Spread your legs some more so I can get a good look at your holes." Melissa obligingly widens her stance, leaning forward against the kitchen counter for support while she continues drinking. You kneel down behind her and pull her asscheeks apart with your hands to inspect her at close range. Her pussy opens up readily as you spread her cheeks from behind, the bright pink flesh of her vagina contrasting deliciously with the slightly darker tone of her labia. You run your thumb back and forth along her slit and then slide it up inside her. Her pussy is wet, warm and inviting. You hook your thumb further up inside her, cupping her labia with your fingers while you feel around in the moist depths of her twat.

The area around her asshole is also a somewhat darker brown tone than the rest of her skin, and her anus itself looks deeply puckered in a way that you recognize from porn stars who do a lot of anal scenes. You pull out of her pussy and tentatively probe at her butthole. Your thumb slips in up to the first knuckle easily, even without any lube other than her pussy juices. She gives a soft sigh that sounds like one of pleasure as you shove your thumb the rest of the way into her ass, but otherwise she continues on with what she was doing regardless of your attentions. "Do you get fucked in the ass a lot?" you ask her, curling your index and middle fingers up into her pussy while you continue to explore her rectum with your thumb.

Melissa makes an mm-hmm noise in reply, and then stops drinking the water briefly in order to answer you properly. It looks like she's about three-quarters of the way through the glass by now. "Yeah, guys really seem to like using my asshole, even more than my pussy," she says matter-of-factly. "I've always kind of liked taking it up the ass, so I don't mind being an anal slut most of the time, although I really don't like ass-to-mouth. Most of the guys who use me do like it, though, so I usually end up tasting my own ass anyway." She shrugs expressively with one hand as if to say oh well, that's life, and returns to finishing off her water with your fingers still up her holes.

After a few more seconds she drains the last of the cup and fills it a second time, though not quite to the top this time. She looks down at you and says, "All set! That should be enough for now, but I'll top off with this later on." She holds up the plastic cup.

"Perfect," you say. "Thanks for being such a good piss whore for me."

She smiles back at you. "No problem, I'm happy to do anything you want me to. Or to let you do anything you want to me!"

You pull your fingers out of her holes and take a moment to admire them again while you're back here. Her asshole is now staying slightly open on its own, having relaxed after having your thumb stretching it open for the last few minutes. You stand back up and turn her around with one hand on her hip. Before doing much of anything else, you'd better wash your fingers...

Wait, no, you think, mentally grinning to yourself. There's a much more entertaining option right at hand, as it were. Instead of washing off in the sink, you stick your thumb into Melissa's mouth for her to clean off for you. As the dirty digit enters her mouth, she grimaces slightly at the taste, but she doesn't resist or complain openly. "Sorry about this," you say, although in truth you feel a perverse thrill at being able to make her do something so degrading, and right after she told you she hates it to boot. "I know you said you don't like it, but I'll probably be going ass-to-mouth with you on a regular basis too, so no reason not to start now, right?"

"'on't wowwy abou' i'," she mumbles around your thumb, and starts licking and sucking it clean. When you pull it out of her mouth a minute later, it's wet with spit but otherwise pristine. She takes another sip of water to wash the taste out of her mouth and continues, "It's just part of life as a public fucktoy. What you want to do sexually is more important than what a cumdump like me wants." She says this in a calm tone, not sarcastically or passive-aggressively; she genuinely isn't upset at you about using her ass and mouth that way. It's just something that happened to her, like bad weather.

"Glad to hear it," you reply. "Here's something that might taste better." With that you stick the fingers that had been in her pussy into her mouth. She doesn't seem to mind that nearly as much, but instead of passively letting her lick your fingers, you push them further in until her teeth scrape your knuckles and you can feel the back of her throat with your fingertips. She makes some muffled wet gurgles as your fingers bottom out, but otherwise accepts them without much distress. "You don't have much of a gag reflex, do you?" you ask, marveling at her ability to tolerate you tickling her tonsils like this.

She shakes her head as best she can with your hand holding her in place, not even trying to answer out loud. When you pull your saliva-soaked fingers back out of her mouth, she explains, "I've had plenty of practice deep-throating, so I got used to having things in my mouth a long time ago. It's an important life skill when you've got tits like mine!" She laughs, her big boobs jiggling as she does so.

"I'll bet," you say with a grin. "Maybe we'll get some more 'practice' in later. For now, just let me know when you're ready to pee again."

She nods. "Yep, I will. After all that water on top of what I drank before you came over, it should only take a few more minutes." It looks like you've got some time to kill before she's ready to wet herself again.
