"Is this what you want?" Julia taunts from above me.

The pain in my nipples as she lightly twists them is good, but nowhere near the level that will truly excite me. After a year and a half together, Julia knows this, of course, but also knows that teasing me will make me want even more, make my release that much more fulfilling. I think she enjoys making me wait too.

"Mmf, mmf," I moan desperately into the hairy pussy grinding roughly against my face, never ceasing the movement of my tongue.

"Or does my little pain slut want even more?" she mocks.

"Mm-hmm," I nod vigorously between her legs. Far from being bothered, I enjoy hearing her laugh at me for how horny I get from the pain she gives me.

"You want me to twist your stupid little nipples harder, Bree?"

My whimpers of desire are swallowed up by the engorged labia covering my mouth.

"Don't you feel stupid, begging for something you know is going to hurt?" she laughs.

I struggle to shake my head against the thighs clamping its sides.

"Then you're going to have to work for it," she taunts, grinding her sodden pussy harder against my face, "and you can earn yourself another reward, too."

We've done this many times, and I know exactly what she wants. With the mask covering my eyes, my only choice is to feel my way as I stretch my tongue higher. I know her body well, and have no trouble locating her large, fleshy clit; I rapidly flick my tongue side to side across it.

"Mm... god, yes. You're a good little lesbian whore, aren't you?"

I've been with her long enough now to be comfortable with my sexuality, but my religious upbringing still gives me a naughty little thrill at being reminded of the taboo. I struggle to shake my head again.

"Did I say you could stop? Keep licking that clit! Or better yet," she slides her hips back, angling her pelvis further downward, "how about sucking on the whole thing?"

I gratefully and greedily take the nub into my mouth. It's slightly smaller than Julia's nipples, yet still bigger than mine, and vastly larger than my own tiny clit. Sucking on her reminds me of the blowjobs I gave in high school, before we'd met; yet at the same time, it's nothing like sucking on a dick. The smell, the taste, the fact that I have to be so much closer to her body... she's right, it's substantially more exciting to be with a woman. Part of me wishes I weren't blindfolded so that I could see the perfect pussy engulfing my nose, but it's also exciting knowing she can do anything she wants with me and I won't see it coming.

"Yes, you ARE a little lesbian whore. You need to be punished for it, don't you?" she taunts.

"Mm-hmm..." I gurgle.

"Keep sucking!" she demands, giving my nipples another twist, harder this time, but still not as hard as she knows I need.

As I suck, she continues to instruct me, though she's becoming less and less coherent. "Mm, harder... nu-- too hard, ease up... right there... mm... yes... now lick-- no I mean keep sucking, but still lick a little also... ahhh yeah... mm... mo-- more now... harder... HARDER-- yes... YES... HARDER!!! YESSS!!!!"

She's using my mouth for her own pleasure, making me hers. When she cums, her fingers finally twist my nipples hard, nearly 360 degrees, just the way I like. Her body arches up, yanking the sensitive bud from my mouth and replacing it with a rush of sweet-salty liquid ejected from her urethra. As I swallow the first mouthful to make way for more, I feel her clit grinding rapidly, frantically, and forcefully against my chin to prolong the orgasm. I moan through a second mouthful of her juices, knowing what's coming next, longing for it. It's strange, there are so many things that would ordinarily repulse or scare me that Julia somehow makes loving, caring, and sexy.

Sure enough, a moment later, the frantic movement subsides and the musky taste of her squirt takes on a more bitter tang as she allows her bladder to continue to empty, panting hard. I've come to enjoy the taste, but more than that, I love the simultaneous feeling of letting her use me and absorbing such a private part of her into my own body.

Her fingers are still twisting my nipples, shooting waves of pain and pleasure downward, directly to my own pussy. Instinctively, my hands reach down to caress it, but the ropes stop me. Julia always ties them at the perfect length: Enough slack to allow me easy access to her as she rides me, but not to reach my own nipples or pussy. It would be aggravating if it weren't also so damn exciting. I change direction to caress the thighs embracing my face instead.

I've been continuing to swallow the warm liquid as quickly as I can, but there's a lot of it and she's letting it go at full force this time; a fair amount is dripping down my cheeks, through my hair, and onto the waterproof blanket below me. I still manage to get at least seven or eight good mouthfuls.

She leans forward, her long hair brushing my thighs as she brings her face toward my pussy. Anticipation flows through me as she approaches; I'm so horny now that I expect to cum the moment her tongue touches my clit. Her hands are still sandwiched between us, her fingers continuing to rub and pinch my delightfully inflamed nipples. I desperately want my release to coincide with drinking her most personal fluid, but she has other plans.

Instead of her tongue, I feel her light breath blowing against my clit. I whimper through my mouthful, wanting contact, but she just giggles and blows harder. I feel her stream begin to subside, and continue to swallow it down until I feel it sputter and stop. Dammit. I had really wanted to cum while she was still going full force.

I continue to hold the final mouthful inside, not swallowing yet, wanting to savor the intimate gift she's given me. I feel her climb off and slide down next to me, and then her tongue gently caresses my earlobe.

"Swallow," she whispers softly.

I let the final few ounces of her precious essence slide down my throat, wishing she could give me even more.

"That's right," she croons gently, "someone was a thirsty girl."

"I'm always thirsty for you, my love," I pant, unbearably horny now.

"Good," she purrs, before sliding down further, rolling her body over my leg to take up a position between my forcibly spread thighs.

Her hands slide, agonizingly slowly, up the sides of my body as she continues to blow on my clit, still not making contact with any part of my desperate pussy. Her palms are finally passing my waist, which means that at the current pace, it'll only be another ten seconds until I finally get to feel them on my nipples again-- but no, as usual, she changes it up to keep me on my toes.

Suddenly, her fingers are wrapped around the bases of both of my small, but well defined, mounds. The fingertips are digging hard into the sensitive flesh from all directions, creating pressure in the breast tissue that sends exquisite pain tearing through my senses. I wish the pain would extend to my nipples, but she's carefully wrapped her hands so that the thumb and forefinger are encircling my areolae, deliberately avoiding them.

"Please," I beg, "please touch my nipples and clit. I need to cum so bad, Julia, please."

The hand leaves my left breast, and I hear the scrape of her phone coming off the nightstand.

"You have forty-five seconds. Cum in time, and we keep playing. Don't, and I go make myself a cup of tea."

I've always liked this game too, even before I taught myself how to consistently win when I want to. There were a few times when she left me alone, tied up and desperate, for what felt like interminable eons. Oh, she always comes back and gives me another chance to cum, usually with a brand-new punishment idea, but the waiting is always unbearable. Even so, there are still times I deliberately let her win, just to see what the new punishment will be. The delayed orgasm is always amazing too.

I wonder what the punishment will be this time. She'd mentioned making tea, which means there will be hot water, so she might decide to make extra and bring it into our play. She's always very careful to keep it right at that temperature that hurts, but doesn't permanently burn, and I briefly consider letting her win as I imagine the scalding sensation on my nipples.

Another scrape of her phone and I feel her move back into position. I hear the ticking of the timer, distracting me, continually reminding me that I'm on the clock. Sometimes I wish Julia would change the app's setting to silence it, but I think she likes the additional tension it gives me.

Her tongue finally rasps against my clit, exactly the way that always makes me cum quickly, and I think to myself that I'm horny enough for just one or two more of those to send me over the edge: an easy, gentle, clit orgasm.

I'm wrong. The pleasant lick had only been a side-effect of her separating my labia with her tongue to get her mouth in closer. The next thing I know, her teeth clamp down on my clit, hard, and she pinches my nipples. My body is a triangle of pain, exciting me to new levels, but also making it that much harder to cum.

I focus on my clit, thrusting it up and down between Julia's teeth as much as the ropes and her weight on my legs will allow. It's not much, but it creates enough rhythmic movement that I begin to feel the warm release well up from within me. Still, I'm not sure if it'll escape in time; I estimate I only have a few seconds remaining.

"Oh god, Julia, yes, I'm nearly there! Bite harder, twist farther, please, please, please!"

I suppose Julia must be feeling benevolent today, because in the next moment, three things happen simultaneously: She bites harder, digs her fingernails directly into the centers of my nipples, and her phone's timer goes off.

"God yes, Julia, I'm cumming! Oh my god, yes, just like that. Hurt me like you love me, hurt me like you love me!"

The phrase wouldn't have made sense with anyone but Julia, yet somehow, the pain she gives always fills me with the deepest and most profound sense of love and care and trust, and today is no exception. The burning in my nipples as she wriggles her nails deeper into the sensitive skin floods my senses, far better than scalding water would have. My clit pulses within its enamel prison, each movement adding another jolt. We're both breathing heavily, barely hearing the cheerful twinkling tune of her timer.

After about a dozen agonizingly wonderful seconds, I descend from my orgasm, still chanting the same mantra, "...hurt me like you love me, hurt me like you love me, hurt me like you love me... oh GOD, Julia, you hurt me so good."

"You're so much fun to hurt," she says cheerfully, and I can HEAR the smile in her voice. "But there's something else I want to try."

She goes back to licking my clit for a moment, the combination of pleasure and lingering pain building me toward the usual series of followup orgasms before she stops again.

"I want you to give me your pee now," she says, shocking me. "I'll give you a tap when I'm in position."

I've received her pee many times, but this is new. As far as I'm aware, she's never had any interest in being the recipient, but I suppose she's more turned on than I realize. All I really want right now is more orgasms, but if she wants me to give back some of what she gives me, I'm willing to oblige.

I feel the tap on my thigh, and relax my bladder. It might have been harder if not for the blindfold, but without being able to see where I'm peeing, I have nothing to be bladder-shy about. I hear the telltale tone of liquid filling a hollow space, and I'm filled with a sense of wonder that I'm releasing something so personal into Julia. If this is how she feels when I drink from her, then it's no surprise she likes doing it so much.

After a moment, I feel another, double-tap on my thigh, our long-established tactile 'stop' signal for when we can't otherwise speak. I tighten my pelvic muscles again, stemming the flow for what I assume will be just a moment to allow her to swallow. I again wish I weren't blindfolded so that I could see it.

Wrong again. I feel her weight shift, and the heat of her face just above mine. She grunts, and I now understand that she means for ME to take it. Drinking from her is one thing, but drinking my own just seems wrong somehow. I clamp my mouth shut and shake my head with an "mm-mm" noise.

"MMM!" she grunts louder, more insistent, placing a finger on my lips to encourage me to open them.

"Don't want," I say quickly, opening my mouth as little as possible.

Strangely, I don't use our safe word, and I'm surprised to discover that this doesn't actually seem to be a hard limit for me. I doubt Julia is surprised at all, though; after all, this is how it always goes when we try something new.

Suddenly, I feel her fingers on my nipples, twisting hard. My mouth opens wide in a moan I can't control. A moment later, the warm, pungent liquid pours in. It tastes different than hers does, more bitter and acrid. At least, I think it does, but maybe it just doesn't carry the same intimate sense of sharing in her body that ordinarily makes me immune to any unpleasantness.

"Swallow," she commands.

I'm still so scared, so unsure. It shouldn't be any different from hers, but it is. It feels dirtier somehow. Julia's pee is always a glorious gift that I can't get enough of, but now that it's my own, I can't get the thought out of my head of what it actually is: waste, urine.

Still, I hear Julia's heavy breathing near my ear, communicating how much the thought of seeing me swallow my own pee is turning her on. I still don't want to, but my mind starts to weaken.

"I know you want to cum again. Swallow it or we're done for now."

Slowly, agonizingly, I allow a few drops to trickle down my throat. It's not so bad, I think, so I steel myself. Clamping my eyes shut despite the mask covering them, I force my throat muscles to contract, and finally, my own waste is sliding down into my stomach. I cough and gag a little as I try not to think about it, but I do it. My heart is pounding; I don't know whether with exhilaration or horror.

"Oh my god, Bree, that was so HOT!"

Her lips are on mine and she's driving her tongue deep into my mouth. I can taste the lingering droplets. After a few moments, she breaks the kiss.

"I want to see you do it again," she says excitedly as she moves back down, tapping my thigh again once she's ready.

Giving her a second mouthful is harder, knowing she'll be bringing it up to my own mouth right afterward. I remind myself how good it'll feel to please her, and finally relax, resuming a steady stream. After a moment, the double tap comes, I stop the flow once more, and she's back up near my face.

This time, I'm prepared. I open my mouth willingly, my desire to arouse her outweighing my disgust. The bitterness resumes its assault on my taste buds.

"Hold on, don't swallow it yet," she instructs.

I feel her face get even closer to mine. Her tongue enters my mouth, and I feel it swirling around, swishing and splashing in the puddle she's filled me with.

"Okay, Bree, now you can swallow again."

I still feel dirty, but it's easier to close my lips and engage my esophagus the second time. Just like the first, she's breathing heavily, letting me know just how aroused the sight has made her. Suddenly, a thought crosses my mind, a way I can use this to turn her on even more.

"Another," I request.

"Another what?" she questions in that tone that means she already knows but wants to hear me say it.

"Another mouthful." I can hardly believe I'm actually asking her to do it again. "Please, Julia."

"Another mouthful of what?" Now I'm sure she just wants to hear it come from me.

I know what I have planned will excite her, and I'm getting desperate. "Another mouthful of pee, please."

"Whose pee?" She knows I've been deliberately avoiding saying it, deliberately focusing on how much it's exciting her instead of the specifics of what I'm doing. I know the latter is what truly excites her, forcing me to be conscious of my boundaries while pushing past them.

"...Mine," I whisper shamefully, allowing myself to fully confront the reality. "My pee. I want you to give me... another mouthful... of my own pee."

"Anything for you, doll," Julia says, as if all of this had been my idea.

If the second round had been difficult, this third one is even more of a challenge. This time, it's me asking for it. Can I really go through with something so depraved?

Once again, I force myself to relax, to allow my waste to flow out into my lover's mouth, knowing that she'll merely be using it as a vessel to transfer it into mine. A moment later, the expected transfer comes.

I hold the puddle there and open my mouth wide, creating as much space as I can. It's only...
