My girlfriend, Carli, had a great body, topped off with outstanding nipples.
Her prominent nipples were always erect during sex, and frequently during non-sexual times, "headlights" often were ON.
Until Carli, I'd been focused on fantasies of me as a submissive, so I knew sub tendencies. I sensed Carli might respond to the Sub role; (certainly NOT a Dom type).
Carli was so shy/embarrassed about her prominent nipples.
She had to wear padded bras, or risk leering men, and scorning women.
Once, while fucking missionary, I held her wrists down, and she swooned.
"You like being overpowered....helpless?"
Seconds later, she orgasmed!
My suspicions about her as sub were correct.
I pounded her pussy, "You like being a little sex toy, Don't you?"
She moaned and nodded.
"You've been a good girl....up to now. Now you're going be a SLUT!"
Still holding her wrists, her eyes rolled back, mouth agape, "Oh FUCK! I'll do whatever you say!"
"That's right slut. You'll do what I say, FULL TIME!"
She moaned, and I withdrew, and straddled her, my butt resting on her pussy.
I began playing with her (hard) nipples, "You have slut-nipples....Don't you?"
She moaned, and I commanded, "Answer me, SLUT!"
"Yes," she gasped, "I have slut nipples!"
"From now on, you wear thin bras, show off those nips, and the world will know you are a SLUT!"
She moaned, "Oh God!"
I pushed her, "You want to dress like a slut, don't you? You want men leering, undressing you with their eyes."
She nodded.
I moved up to her face. Her mouth opened, and I fucked her mouth.
"Swallow every drop," and she moaned and nodded.
I put a pillow under her head, "That's a good cocksucker. Work that tongue. I grabbed my phone and recorded her sucking me off."
She moaned, and I blew my cum into her mouth, and she sluttily gulped it down.
I rolled off her, and laid on my back, Carli on her back next to me. I noticed she was idly touching her nipples.
I smiled, "You still want more?"
She panted, "Fuck Yes! That was SO unexpected! That was the best sex! I never imagined sex like that!"
Even though I'd just cum, I engaged, "Ok slut, straddle my waist."
What a sight! Her petite body, with pouty breasts, and oversized nipples, at my disposal.
I ordered, "Masturbate. Make yourself cum. And tell me your fantasies as you masturbate."
One hand to her clit, and one to her nipples, "I want to be a slave! Make me do things. Make me go out braless! Make me dress like a slut!
Train me. Make me be a slut in front of others! Make me your fuck-toy! OH FUCK! I can't help myself! OH FUCK, I'M CUMMING!"
I smiled, "Lick your finger."
Without hesitation, she sucked her finger.
I rested on my pillow, "Your pussy gets shaved today, but first, bring me all your bras."
She dumped a pile of bras on the bed next to me. All but one was padded.
"This is your only bra for now. We're going shopping, and from now on, your beautiful nipples are on display. If I catch you in a padded bra without my permission, you'll be punished."
Her face was red, "I, I, can't really do that! What about work?"
"We'll establish rules, but you just told me you want to be forced, so things are going to change. Put on that top," I ordered. It was a sheer camisole with spaghetti straps.
Her nipples poked thru like acorns, "Oh God," she said.
I pointed out the obvious,
"You've worn that top in front of me many times, your nipples protruding, prancing around the apartment as if it was nothing. You've wished you could show the world your hot nips!"
She whimpered, "Not the whole world....just some people."
"For now," I continued, "Lets get you shaved."
I put a few pillows against the headboard, then tied her wrists to the sides, and then her ankles. I brought out a razor, cream.
Still wearing the cami, her nipples were protruding rocks, as I began to shave her beautiful pussy, "Look at your nipples. You can't help yourself. Your pussy is gushing, and your nipples are so..."poised". Perhaps you'd be a good bikini-slut. We'll get you a thin little thong, and top, and when wet, they'll cling to your little slut body, show off your nips, and all the boys and girls will get a thrill."
Tied spread eagle, Carli couldn't contain herself, "OH FUCK, OH FUCK, OH FUCK!"
Moments later, her pussy was bare, "This is how your pussy stays. Every day, you shave. Soon enough, you'll be lasered."
Carli was literally panting.
I had a huge dollop of precum oozing forth, and squeezed it onto my finger and stroked her pussy, "Look at those nipples popping thru your top. That's a good look; your new look."
"Answer your Master," rubbing my cock up and down her slit.
"Yes Master," she gasped.
I continued, "Who are you?"
"I am a fuck-toy slut!"
I plowed my cock into her, and she strained on the bindings at her ankles and wrists, "Oh! FUCK ME! FUCK ME! FUCK ME! FUCK ME!" Over and over she mewled and groaned, and "AHHH! AHHH! AHHH!" She came like she'd never cum before.
Having cum earlier, I lasted a bit longer, "You like being tied up?"
"Yes Master!"
I plowed away, her grunting at each thrust, and finally blew my load, deep and hard.
Then I left her, still tied up, and headed to the shower.
Exiting the shower, she was still tied spread-eagle to the bed. A towel around my waist, I walked past her as if she wasn't there, to the kitchen, and returned with a beer, which I set on the nightstand.
Her body was a bit sweaty, and the cami clung tight, and her nipples protruded, my cum oozing out of her pussy, "Is slut ready to go shopping?"
"Yes Master," looking me in the eyes.
This was REAL! She'd gone from girlfriend to slut-in-training!
I laid next to her, raised her cami, and took a nipple in my mouth. "OH FUCK!" She panted. Then the other nipple, back and forth, Carli bound spread eagle, I teased and sucked, while she moaned and groaned....and we dozed off.
We awoke in an hour or so.
"Please," she said, "untie me."
I slid my hand down and stroked her freshly shaved pussy, and she groaned, "OH! OH FUCK! I can't take it! Please!"
She couldn't help herself, and began moving her hips, and I mouthed her nipples as I stroked her pussy, "OH GOD! OH FUCK! I'M SUCH A SLUT! OH FUCK! OH FUCK! I'LL DO WHATEVER YOU SAY! PLEASE FUCK ME! OH FUCK! YOU OWN ME! YOU OWN ME!
As I fucked her I spoke to her, "Say it," I commanded.
She panted, "I'm a slut! I've always wanted to be a slut! Thank you for making me your slut!"
Her pussy gushed! I reached behind and grabbed her ass cheeks as I fucked her, and she was soaked. I ran a finger over her asshole, and she groaned, "OH! OH! OH!" And then I slipped my finger in her ass, feeling my cock thru the thin membrane, and we both came.
Laying quietly in afterglow, I eased my finger from her ass and she grunted.
Untying her, I smiled "Lets go shopping."
I selected her outfit, and she looked at herself in the mirror, and sort of panicked.
I reminded her, "You are my slave-slut. Put this on now or you'll go out shopping with a plug in your ass." I was coming to enjoy the "Dom" role.
She put on her sheer bra, and a tight little top. Even soft, her nipples to poked nicely, and when erect, it was almost obscene. Her thong panty was sheer....barely there. Her skirt was short and thin, along with 3" clogs.
We walked along, acting as if we were unaware, while she got varieties of stares; appreciative men and boys, and disdain from women....and teen girls, who stared with wide eyes, some judging, some hoping.
Carli was "exhibiting"; she was starting to enjoy the attention. She actually smiled at some 14-ish boys, who couldn't seem to look away. She said to me, "Yes Master," loud enough so they could hear her, and they snickered, laughing loudly, (but dreaming wishfully, having been given new masturbatory material for that night.)
We purchased a few new bras with thin cups. We also found some tops that would look very slutty.
The boundaries for slut Carli quicky evolved.
She'd wear a padded bra to work, but keep a sheer bra in her car, along with "display" clothes, in case we met right after work.
Around her folks, a padded bra allowed, but NOT with friends, no padded bras.
We'd meet friends for dinners and she'd beg, "Please! I can't go out like this!"
I'd smile, and force her, and once forced, Slut-Carli enjoyed the public attention, and showed her gratitude when we'd get home, "I'm your slut slave! Thank you for making me go out this way!"
I'd demand, "What way?"
She'd shyly answer, "Showing off my.....nipples," (still a bit shy).
"Go on," I'd prod.
Cringing, she'd say, "I like it, people seeing my nipples."
And then, "OH FUCK, PLEASE FUCK ME! I'M SUCH A SLUT!"
Carli had a close relationship with her stepbrother James. He asked about her new dress-style, and Carli explained, "We're spicing things up a bit, you know, a Master and slave thing."
James replied, "Really? I can see you in a Sub role, but I don't see him as a Master."
Carli told me about their conversation, telling James it was really exciting, and she enjoyed me as Master.
James lived out of town, and stayed with us for a few days each month for Business. Each monthly visit, he said nothing, (to me, anyways), but knowing that he knew....it was the elephant in the room. He and Carli arranged for James to visit for a long weekend, in addition to his business.
He arrived on a Friday evening.
