My girlfriend insisted on my safety — and it only heated me up.

A fault line had opened. Wet and swollen — overlooked by my thighs and the delightful curve of my feminine ass. Our night of experimentation had stretched into two weeks.

I unloaded our Sunday groceries, consumed with an unspeakable worry that had been plaguing me since I woke up. I looked reluctantly at my girlfriend and then placed the silvery package of seven pink pills on the counter next to the bananas. "Another week?!" my girlfriend exclaimed. I bit my lip and shrugged. Why not?

"All the more reason to take precaution." My panties felt a bit tighter when she said it. Precausion.

"Two weeks is a significant dose. Large dosages of my cum could confuse your body and make it hard for you to come back."

Her cum? Fuck. I pressed my thighs together and tried not to wince as I reached in and fished out the matching package of seven glimmering blue pills.

It wasn't lost on me what I was requesting. Inserting my card into the reader to buy these seven blue bad boys meant one thing: My girlfriend would have a cock for another week.

And I would be the girlfriend.

I cooked dinner. Moving fluidly around the kitchen. Dishing a delicious meal onto our plates. Delivering it into my boyfriend's strong hands. Could she see I was better at being the girlfriend anyway?

We ate dinner quietly and I tried to ignore the thobbing head of her cock swelling in her jeans. I had become deft at spotting it and it made my mouth water lately.

I had avoided her cock as a temporary fiction, pretending it was merely her clit looming large and ready for my pussy's pleasuring. I had avoided asking to go down on it — I was already too far down the road of self denial to risk it. But over days I began to find myself on my knees in front of her, looking up at her trying to appear innocent, my glance darting between her loving gaze and the reality now throbbing, pitched high into the air.

She looked down and smirked. "What is it? Do you want to go down on me?"

"Oh. . . " Oh, god. I tried to look natural, tried to search for some plausible deniability. "Oh, I just like looking up at you. I mean. . . would you want me to?"

Her smirk deepened. She doubled down. "Don't you want my cock in your mouth?"

My pussy puffed up in an instant, glimmering with my lubrication, impossibly wet and yearning the air between my thighs for entry. My eyes darted fastered between hers gaze and her cock. And suddenly I was going for it.

She stopped me with her hand. "You'll need protection." Fuck.

It was maddening to have anything between us. It stirred me up.

How I relished this though, quickly deciding on her approach to applying it. It amounted to a parlor trick — but it beat sliding it on with my fingers.

I needed to feel her skin traversing my lips slowly. I needed connection.

I looked up for approval. Halfway traversed, I lost myself in the halocline of our sexualities.

I looked up for approval, a woman entirely, my boyfriend's cock in my mouth.

I suck my girlfriend's cock like I mean it.

I don't give her any choice but to come, yearning and inviting her explosion with my tongue. So warm in it's containment. And so much.

I keep her balls in constant production. At some point, two weeks ago, a solitary egg within her burst forth with a tail. Then another. In quick succession her swelling ovaries filled with deft swimmers, even as deep in my balls my sperm was losing their mobility. Floating passively in wait, even before my balls condensed and popped inside my pelvis on the way to their new placement.

She let's me play.

I like how warm it is on my lips, I say. On my tongue.

It's reproductive potential isn't lost on me. This cistern of her seed could impregnate 300 million women. And this one pearly white load, confined and impeded, is entirely mine.

I play, the feeling of the room suddenly hesistant. The danger of leakage, of a tear, present in the air between us. I think about that happening.

I think about snagging the tip of the condom with my tiny feminine teeth by accident.

And on purpose.

My jaw is sore. It could happen so easily if I didn't keep my mouth wide. It could easily be explained away.

And I wonder what she tastes like.

So begins our third week — another forced extension of what was meant to be a night.

This isn't the new normal. We've fucked a lot in the past two weeks. She holds me close at the end of coupling. Cuddling me close. Oxytocin and estrogen coursing through me, my masculinity washed out in their cocktail.

In those moments I know one thing. I love my boyfriend. I always spend the rest of the day giddy and feeling complete freedom of my form.

I turn and see her watching me. A masculine consideration of my pussy revealed. Her jaw strong. Her eyes pleased. Her mind reverting to local processing. The primal male gaze initiated. Viewing me as an object to be used. She's gone that quickly. I'm left with a man behind me with a throbbing cock and my pussy throbs.

I need his cock in my pussy. She needs it.

I'm thinking with my pussy.

How could I not. My ovaries dole out delightful doses of estrogen as I go about my day. And my little clit swells in my panties. It has become my cock by proxy. My source of pleasure. The sensations are so strong in my new body I can barely even remember what I felt like before. My skeleton restructured, my hips bones expanded, I sway when I walk, and my little ass bobs behind me.

I need my pussy. And my pussy needs cock.

So on Sundays, when I round the corner at the grocery store to the pharmacy section, I buy another round of blue pills and lock my cock down for another week. I barely consider that every time I set them on the table for Katie, I'm saying "I like you this way."

I can barely face that every inch of growth added to her clit as it turned into this cock was her clit moving an inch closer to my preference.

What does he see when I'm like this?

The last few weeks I've held back, trying not to look eager. But tonight I can't help but fall into complete surrender to what I need.

My lips apart. My pussy filled. The continued pressure building inside of me.

My girlfriend slides out, my pussy aching for return. And then he thrusts. And this happens in close succession. Light a lightswitch flicking on and off. I move back to meet it. The skin of my balls pulled tightly against me into a little camel toe of pleasure that hugs my boyfriend's delicious cock.

"That's right. Fuck me like that. Fuck me with your cock."

He moans and connects harder. I fall back and ride him, aching in the futility of the condom between us.

I'm so wild tonight.

Unhinged and letting go.

My little pussy wants it so bad. We can both feel the charge we are building in this room. Two packages of pills lie on the counter, each missing a pill. Our third week of dosage.

Suddenly it's hard to see a way back, and my nipples perk up like little marker caps. I wouldn't mind if there wasn't one.

I move my hips slightly and suddenly the pressure builds. I'm going to come. I fuck her to my edge and then cry out, "Oh fuck, yes! I love my boyfriend's cock!"

I can hear her sigh out behind me, like breathing herself out. And her cock swells so much inside of me it feels like double. Oh god. I said that. I sit and my girlfriend moans out deeper than I've ever heard. It reverberates through my diminutive female frame. Her cock swells again.

Hurry.

Hurry, before it's too late.

You have him lost and desirous. You can do it now. He won't stop you.

God, that's it. The feeling of my lips transfered deep against the walls of my pussy. Oh, fuck yes. That's right. Get wet with me. I need you slick. I need to pulse around you and work your big cock.

My girlfriends moans deepen. I turn back to see her return to her eyes for a moment with a look of shock. I know the feeling. When you can't hold back anymore. It's okay honey. I sit back. I'm not going anywhere. It's okay.

Come inside of me.

Her eyes glaze over and he returns. He moans out and comes deeply.

When he's done shot after shot I lift up so he can see. He looks. I really like showing him.

Bliss washes over us and I fall back into his arms and delight in him dripping out of me. After a few minutes he speaks.

"What should we do tomorrow?"

"I was thinking we could go have a picnic by the lake. I bought a new bikini."

Our pheramoes dance and interplay. Our fluids combine and meet. A delightful confusion is spurred within us. My boyfriends soft cock begins to harden again.

I pulse my pussy in relief, knowing there's no chance it's going away now. That's what I was worried about today on my way to the grocery store.

That it would go away.

I pulse around my boyfriend in the park, basking in my feminine nature. I knew he'd give in.
