Bestie Boyfriend

BESTIE BOYFRIEND

My younger sister Ashley had always been a total bitch about me being gay. She loved to tease and torment me about it... not that she was homophobic, but just that she thought I was too much of a boring loser to be gay and was just saying I was for attention.

Ashley was anything but boring. She was a mean naughty bully who nearly got expelled twice for bringing alcohol and drugs to school and then the second time she was found sucking off other students in a stall in the boys bathroom (there was apparantly a queue forming).

Ashley always dressed like she was a porn star and I had no doubts my slutty sister would end up on Only Fans. Sure enough she started an account as soon as she could and was soon fairly Internet famous as a dirty slut. With enough money to do what she liked she was a narcissistic evil bitch who was superficial and fake. A total diva who seemed to love making my life difficult. 

Of course her antics sort of pushed other girls away so by the time she was eighteen - most of her 'friends' had distanced themselves. Ashley didn't seem to care though. She'd found herself a new friend... my boyfriend in fact.

I'd met Mike over Grindr and what had started as a casual sexual relationship had transformed into something more steady. We'd begun dating and even moved in together. Mike was funny, clever, handsome and always fun. He and Ashley hit it off immediately.

"OMG I can't believe you're dating my loser brother. You're too fucking cool to hang out with him. You could do so much better."

Even though Ashley has nothing but contempt for me, she seemed to enjoy Mike's company and she began to tolerate me more now Mike was around to distract her. I thought it was a good thing although it was a double edged sword. For years Ashley had ignored me, but now she was back hanging around so she could spend time with Mike.

I was kind of jealous of how intimate the two of them seemed to be getting. Unlike me Mike enjoyed clubbing and drinking and the two of them would go out together whilst I stayed home.

Then when our landlord kicked us out, Ashley let us move into her huge condo with her.

"You're lucky I like your boyfriend maggot or I'd throw you out onto the streets. Youre a pathetic excuse for a brother."

Living with Ashley was hard. She constantly belittled me and it was hard to find time alone with Mike. My sister and he were as thick as thieves. 

"Like OMG you're like totally my soul mate," giggled Ashley one day as the two of them drank cocktails at 5 in the afternoon and I watched with irritation. "Like I wish you'd been like born a girl and we'd be like besties and we'd pick up guys together and like go shopping and ooooh we could like suck cock together. You could even dump this fucking loser and find a hot guy."

I rolled my eyes as the two of them burst into hysterical laughter. It just seemed like another one of those dumb mean things my sister said. Mike thought she was joking but neither of us had any idea there might be anything behind it.

***

It was a few days later and Ashley had been acting more sneaky and weird than usual. I knew she was up to something.

"Ohhhh pleeeeeease," pouted Ashley as I walked into the kitchen and saw her arguing with Mike. "Just try it once, it will be SO much fun."

My sister was holding a vial of some sort of pink liquid. She seemed to want Mike to drink it.

"Girl I love you to bits, but I am not becoming your slutty wing-girl for the night. Who knows if this Elixir stuff is even safe?"

"It is! One sip and you'll become a hot girl just like me. Imagine it, we can dress up, go out clubbing. You'll love the attention! Please Mike, I really want you to become my bestie."

"We already are besties aren't we?"

"But this will be different. We'll be treated like princesses wherever we go. Hot straight guys will be all over us, we'll get free drinks, VIP access, gossip in the girls bathroom, doing each other's makeup... holding each other's hair when one of us needs to spew."

"Ummmm sounds delightful," said Mike, but I could see he was wavering. Ashley could be VERY persuasive.

"Woah, don't I get a say in this?" I suddenly interjected. "What are you guys planning, this sounds insane."

"Shut the fuck up loser. This is nothing to do with you. I got hold of some Elixir and I want your boyfriend to girl-up and join me for some fun. It will swap his gender temporarily and let him finally take his place at my side as my true bestie. Don't worry he'll turn back... eventually."

Ashley grinned nastily. "Anyway Mike, I'll make this even easier for you. If you don't want me to kick out my loser brother you better do as I say. Drink up... like a good girl. I know you want to."

Mike looked at her for a moment, then shrugged. Before I could stop him, he took the vial from her and drank it all. Ashley clapped her hands together excitedly. "Yay fuck yeah. Soon you'll be a bitch like me."

She turned and smiled at me cruelly. "Your boyfriend is gonna be mine now you piece of shit. Soon SHE'LL be just like me."

Mike's eyes suddenly fluttered as the Elixir coursed through his body and he gasped in pleasure. "Mmmmh tastes sweet, I can feel my skin tingling. I feel kinda good."

Ashley grinned triumphantly. "Won't be long now. I can't wait to see you become hawt." She looked at me again and smiled nastily. "Oh you have no idea what's coming."

I could see my boyfriend was struggling to contain his pleasure.  He was flushed and his eyes had a glazed look. Suddenly he jerked his hips and groaned. I heard popping and cracking sounds as his body twisted and bones and body mass shifted. Mike was over six feet tall but suddenly he was shrinking and becoming more feminine looking as his whole body began to transform.

His masculine body was becoming skinnier and smoother with soft skin and no body hair. He actually looked like a twink for a moment as he became more youthful looking and he lost male muscle tone. Blonde streaks shot through his hair and his face became softer and more feminine looking. Somehow it looked meaner already though.

"Mmmmmh this feels goooood," he moaned - a strangely feminine sound as his voice began to rise in pitch and unbreak and he ran his hands over his changing body.

"Doesn't it? Don't fight it... let it overwhelm you. Become a slut just like me, let yourself become a fucking bitch," encouraged Ashley.

"Ooooh fuckkkk yesssss." Long nails sprang from Mike's fingers and his skin bronzed and tanned. Pushing out his chest, Mike groaned as two small but perfect breasts pushed slowly outward and as his clothes fell down I saw his beautiful cock, which I'd sucked many times, was shrinking away.

"Haha you won't need that for long. Get ready to join the pussy club, you're gonna love being one of the girls," gloated Ashley.

Seeing the ultimate symbol of his masculinity shrinking away gave me a strange feeling of grief. I felt betrayed by my boyfriend. I also felt a strange jealousy I had not expected to feel.

Mike was shaking out long soft silky hair. He was giggling as his hips widened and between his legs I saw the pink folds of a perfect pretty pussy open up. He was fully female now with a round bubbly fuckable ass, pretty facial features and breasts. My boyfriend had become my sisters bestie for real.

"Mmmmh I think it's nearly over," he gasped as he shook back his hair and adopted a more feminine posture. "You were right babe, this feels incredible."

Mike groaned as the last micro changes completed and his transformation into a hot 18 year old girl completed.

"OMG, I feel so amazing," purred Mike savouring the sound of his bratty new voice and adopting Ashley's dramatic way of talking instantly.

Squealing excitedly he embraced Ashley and the two of them bounced up and down like over excitable groupies screeching and giggling like crazy. "THIS IS GONNA BE FUCKING EPIC!"

I could almost taste the estrogen in the air as they babbled excitedly at each other, eyes shining as they hugged. "Come on," laughed Ashley grabbing Mike by the arm and yanking him towards the stairs. "We'll go to my room for some girl talk. I've got so much to teach you."

She shot a nasty look back at me. "Don't disturb us you fucking loser, this is for girls like us only."

They were gone for hours. Occasionally I could hear giggling, excited screaming sounds and crashing as Ashley tore through her wardrobe. Presumably she was showing Mike how to get ready. 

I just hoped that this would be over soon. The Elixir would wear off after tonight and Mike would go back to normal. It was weird him being female, it didn't seem right. I was also worried about my sister influencing him. She had never liked me.

Suddenly I heard the sound of heels outside the door and it crashed open.

The woman who walked into the room was stunningly beautiful. Her red heels clicked as she walked with poise and precision into the centre of the room and tossed back her blonde hair like a super model. 

"So what do you think?" she smirked. "I'm a natural right? Me and Ashley decided I needed a hot girls name so you can call me Mia now. Mmmmh I think I was born to be a hot bitch."

"You bet you were girl. I can't believe how fast you learned to walk in heels. The Elixir is rewiring your brain just like I hoped it would  I think we're ready to go out to the club. I just need to finish getting ready," giggled Ashley from behind her. 

She shot me a venomous glance. "You're staying here tonight bitch. Girls only."

Whilst Ashley was gone I turned to Mike. "What the hell are you doing Mike?'

"Oh chill out, don't be such a fucking loser. Gee Ashley is right, you're kind of a fucking killjoy. Look it's still me in here. I'm just having a little fun. Me and Ashley are gonna go out and party and tomorrow it will all be over..."

Ashley suddenly appeared at the door again. "Ughhh. Why are you wasting time talking to that total failure? Let's leave this nobody here and have our girls only night out. I cant wait."

Linking arms, the two of them left in a cloud of perfume and hormones. I really hoped nothing bad would come of this.

***

I went to bed about 3AM with no word from the girls. I'd have been worried but it wasn't unusual for Ashley to stay out for an all night bender and now presumably Mike... or Mia... or whatever she was calling herself would be just as bad.

I drifted into sleep and didnt sleep well. When I woke up I could hear a strange noise downstairs. Creeping down the stairs I saw discarded clothing. Ashley had done her usual trick of staggering to bed drunk and taking half her clothes off on the way. I could hear grunting and moaning from her bedroom, she had brought a guy back with her, but there were other sounds downstairs. 

Creeping down - I saw the living room was open. Peering inside I saw Mia lying on the couch with a laptop open.

She was watching porn, straight interracial porn, and rubbing herself off. "Mmmhhh oh fuckkkk yessss, I fucking love this pussy."

Round and round Mia rubbed her clit and moaning she orgasmed again. "Ohhh fuck yeah, mmmmh I can just keep going again and again. I love it. I never want this to end, I love being Mia."

"Mmmh all those guys in the club, dancing with us, touching us... it felt so good," she moaned. "Their hands on my ass, their lips on mine. Dancing and grinding my perfect ass into their crotches and feeling their dicks swell up nice and hard."

She moaned and rubbed faster.

"Back at their crib. All that big hard cock in all our tight holes. Now I know how good it feels to get my pussy fucked, I want MORE. So much fucking cum, sweaty bodies and the sounds of cock slapping into tight female flesh. We were bad girls and I loved it. I need more!"

Mia screamed as she began to squirt. "Yesss Ashley is right. I'm a fucking bitch and my boyfriend is a loser. I'm so much better than that flop. He could never understand how fucking GOOD it feels to be a popular mean girl. I want MORE. I want to be nasty and bad ALL the time. I love being a fucking bitch." He began to cum again.

Horrified at what I was hearing I backed carefully away. I was too scared to confront Mia and too tired to deal with this so I went back to bed and my head whirling tried to get some sleep.

***

When I woke up the next day, Mike was lying in bed next to me. He was back to normal... well other than the mascara and lipstick he'd forgotten to remove before bed. 

Disgusted at him I slipped out of bed and made coffee. A few hours later Ashley and eventually Mike showed up. They gave each other a secretive smile as they passed.

"Great night last night," grinned Mike. 

"You bet babe. Maybe Mia will come out to play with me again?"

Ashley turned to give me a look. "What the fuck are you staring at dummy?" I hurriedly averted my gaze as the others both laughed.

I hoped I would never see Mia again. I decided not to talk to Mike about what had happened. Maybe it was all over now. Mike seemed back to normal and hopefully everything would now be fine.

A MONTH LATER

"Sorry but I guess I'm just tired."

I let go of my boyfriends flaccid cock and sullenly rolled onto my side of the bed. Mike and I had barely had sex once since his night out with Ashley a month ago. It was like he wasn't into me anymore.

"You know I'm going away tonight - you've been acting weird since you took that Elixir. What's wrong?"

Mike shrugged. "Nothing. Maybe you're the problem. Youre so fucking dull. You never want to go out with me and Ashley and you're such a fucking sulky loser. She's right you are kind of pathetic."

For the last month Mike had been a virtual stranger to me. He and Ashley now spent even MORE time together. Mike's dalliance with Mia seemed to have unlocked some obsession with femininity within him. He now went shopping for clothes with her, attended her hair and nails appointments. It was like he had actually become a girl. The two of them were like sisters. He had also become increasingly bitchy and mean.

I also was worried that he had become Mia again. Mike sometimes smelt of Chanel No.5 and I found a bra under our bed that wasn't my sisters. He and Ashley would stay out late and I had no idea what they were up to.

"Whatever you asshole. Well enjoy yourself whilst I'm away," I sniped - angrily jumping out of the bed. "I wish you'd never met my stupid sister."

I jammed my things into a suitcase and made my way outside.

"Fuck you Mike you fucking asshole."

***

I was supposed to be staying in another city for the night after going to a conference for work, but as my anger cooled I began to feel bad about how I'd treated Mike.

Arguing with him would only push him into Ashley's arms so ai decided I would instead get an early train home and try to make up with him. 

As I walked up to our apartment that evening I could already see there was something wrong. Strange cars were parked up front and there were bright lights on in the house.

I snuck round the side and peered through a window into the living room. 

Inside there were about eleven hot guys. They were all completely naked with their cocks in their hands which they pumped slowly to keep them hard. Each guy was fit, tall and well hung. There was no one there under seven inches.

The studs were standing in a circle around two slutty girls, all expect five of them who were already balls deep inside the sluts in front of them.

My sister Ashley was one of the girls. She was riding one guy in her tight pussy and had another guys big cock in her mouth. Her hands were busy pumping dicks and keeping them hard. I had never seen anything like it.

Next to her was another hot slut. I couldn't see her face at first as her head was thrown back... but she had three cocks inside her. Her legs were bent flexibly back behind her head allowing easy access to her two tight holes. Meanwhile she was busy blowing another cock upside down.

As a guy pulled out of her she lifted her head and I saw who it was. Mia... it was Mia.

Mia and Ashley were dressed in sexy black lingerie. They had pornstar makeup on and hooped earrings dangled from their lobes. As I pressed my ear to the window I could now hear the muffled sounds inside.

"Yessss fuck meeee," whined Mia her face an expression of pure pleasure as thick heavy cock pistoned in and out of her tight pussy and asshole. "Yesss make me your slut."

Meanwhile Ashley was screaming and squirting, riding hard like a dirty little bitch as her pussy exploded and hot juices shot out. They waited until she'd finished gushing and then a new hard cock sank deep inside her causing her to moan in pleasure as her next orgasm began to build.

Wet slaps, grunts of pleasure, female moans and gasps... it was like a scene from a porn movie. 

In fact two of the guys were recording everything on their mobile phones.I ducked back out of sight as the guys all shuffled round. Two new guys took their turn with the girls whilst the others continued to jerk off.

I couldn't believe Mike had taken the Elixir again. I couldn't believe how much of a slut he was.

Mia giggled as one of her lovers suddenly stepped forward and jerking his dick began to cum over her face. She stuck out her tongue as thick white spunk went all over her. "Mmmh give me more..." she groaned. "Fucking baptise me."

One by one the guys stepped forward to cum over her or Ashley. The giggling sluts moaned and cooed as each guy took his turn, complimenting them and encouraging them to blast them with cum.

"Fuck yeah, this gang bang was amazing," giggled Ashley as the last guy finished over her.

"I know right. But with your boring brother away this was our chance to have some real fun. I'm so gonna enjoy breaking up with him when he gets back."

"Really? Why not keep dating the loser, dangle the hope you'll turn back into Mike and keep tormenting him?"

"Hahah you're so fucking evil Ashley. I love it."

Hugging the two girls laughed as more cum dripped down their faces and over their tits.

"Fuck yeah babe, I want you at my side being a dirty bitch forever."

 

Kissing and moaning the two sluts made out, sharing cum and French kissing it into each other's mouths. The first guys to cum were now hard again and they jerked off again sending more spunk flying over the moaning sluts. It dripped down their faces, coated their hair... confirming them both as hot slutty sisters forever.

"Yessss once I take that Elixir overdose Ill be a slut for life. I cant wait."

I was so engrossed in what was happening inside that I didnt hear footsteps behind me until strong hands clamped down on my shoulders and a hand slid over my mouth...

****

"Hahaha what a loser!" laughed Mia as I was hurled in front of her and Ashley.

"OMG the little simp came home early to try and fix things. Too bad. You're too late loser. Mia is in control now."

Strong hands grabbed me and I whimpered as my head was forced down onto Mia's chest.

"Yeah lick up all that cum bitch boy."

Ashley laughed and grabbed one of the guys. Pumping his cock she grabbed my head and I slid the dick into my mouth.

"Can you still taste Mia's pussy juices loser? She hates you now just like me. But you can be our little cocksucker for life."

"Thats right loser. Im a fucking hot girl now and you're nobody. I'm gonna love helping my bestie torment you." 

The two girls laughed, and as I gagged on cock I knew that I had lost my boyfriend.

Mia was Ashley's bestie now and I would never get Mike back.
