I was in my late teens and I had 4 female friends and only 1 male friend.
I was not sexually or romantically involved with any of them in any way but they where all comfortable enough around me to do things like get changed and shout me to talk while they where in the shower or on the toilet. I was the same it didn't bother me at all as they would quite happily come into the bathroom when I was in the shower.
The girls and I where in Stacy's flat having a few drinks just the usual Friday night for us all talking and watching films. As per usual I was on drinks duty and I could hear the girls giggling away, nothing unusual there.

When I got back into the living room from the kitchen Stacy and Emma got up and went out of the room and through to the bedroom. Kirsty gave me a look and went "pfft" while rolling her eyes.
At that Sarah said "right gotta pee" stood up and grabbed my wrist "your coming so I have someone to talk to, Kirsty is boring" and she stuck her tongue out at Kirsty who again just rolled her eyes.

Dragged through to the bathroom I sat on the edge of the tub and Sarah proceeded onwards with her task. "I haven't asked you how your day was earlier yet." She said.
"Nothing much to tell, quick shift at work. Nothing special." I replied.
"OKAY DONE!" She shouted, which was weird to say the least.
"Lets see what those two are upto." Sarah said as she again grabbed my wrist and pulled me towards the bedroom.

At this point I was still none the wiser as who what was up with her but I thought it must just be the drink.
As I was pulled into the bedroom I seen Stacy and Emma on the opposite side of the bed and I was swung round by Sarah and ended up sitting on the end of the bed. As my backside hit the bed the door closed and Kirsty was in the doorway.
"What's up? Something wrong?" I started to get a bit uneasy.
"Nothing is wrong at all Jack." Emma said with a big grin on her face.
"We where just thinking on something while you where in the kitchen earlier" giggled Stacy.
"What?" I looked at each of them to see if their faces would give away the plan.
"Just a little experiment." Kirsty said pointing to the slinky red dress hanging on the door of the wardrobe. (Can't say I have ever seen that dress before)
"Experiment? For what?" I was starting to wonder what have they got in store for me.
Sarah said "for you looking like a girl."
"No way, not happening." I said as I stood up to leave the bedroom.
"Your not going anywhere." Stacy said as her and Emma pulled me back on the bed and pinned my shoulders down.
"Yeah this has been our plan all night." Kirsty finished as she came over to help keep me down.
"Get off me." I said to the girls at my head.
They just shook their heads and grinned.
Mean while I didn't notice that Sarah had made her way down to my legs, I felt a tug as my shoe was pulled off. Then I felt my jeans getting undone. As the other shoe was pulled off aswell.
"Right that is enough you can't be serious?" I said.
"Deadly serious" Stacy said as her and Sarah yanked off my jeans.
"Don't forget the top half girls" Sarah said.
I fought a bit more to try and get free but with 4 girls holding me down there wasn't much I could do but let them get on with it.
I actually started to enjoy it at this point getting all my clothes ripped off by in my opinion 4 attractive girls. So much so that I started to feel a bit turned on by it.
"Right you no fighting it your tshirt goes aswell" Emma said as she pulled my tshirt over my face.
I arched my back a bit to let her get it off me easier.

With nothing but my boxers left the girls had a little giggle as I had now gotten a semi. The girls had seen me in the shower sho have seen it all but they have never seen me get hard before.
Kirsty leaned over me boobs squashed into my face. She wiggled my semi on top of my boxers "looks like someone is enjoying themselves just a bit."
"Off with these." Sarah said as I tried to bring my arms down to not let my boxers be taken off me but I couldn't move and my now erect penis was on show for all to see.
"Up you get." Emma said as she pushed me up onto the edge of the bed.

I covered myself as best I could with my hands.
"No need for that we have seen it now." Stacy said lightly slapping my ass "Time for you to get dressed."
"Yup time for this step in." Kirsty said as she put the dress out for me to put on.
Reluctantly I put the dress on with the help of Kirsty and Stacy. while the dress was being pulled up I could feel my butt being squeezed as to who done it I didn't know.
"We got this especially for you." Said Emma and all the girls had big smiles on their faces.
All I could say was "it's nice."
Sarah said "I thought you would."
With the dress up and on Kirsty zipped it up at the back. Somehow it fitted perfectly, they really thought this through I thought which made me wonder what else was in store.

Emma had gotten her phone out and took a few quick pictures of me standing in my new dress with my bulge sticking out. "What are you doing?" I said
"You are gonna put on a show." Said Emma
"Yup our own private show." Said Sarah
"Doing what?" I replied
Stacy turned on the cd and it was some slow sensual music. "What ever we want and when we want it" she said then she pulled me close and kissed me hard. Again I felt hands on my butt but this time it was spreading my cheeks apart. "What ever we want." Kirsty whispered in my ear.
"First off pop your cock out from under the dress we don't want to get it messy just yet" said Sarah slyly.
They all sat on the end off the bed and just stared at me looking me up and down.
"Turn around and bend over for us." Emma ordered "lets get a good look at that ass"
I done as I was told leaning on the dresser behind me. I could see in the mirror the girls had the biggest naughtiest grins on their faces they
all looked at one another and nodded.
"Feel your balls for us." Said Stacy
As I put my hand between my legs and started to feel my balls infront of them I started to feel more turned on and I started to get even harder, I could feel the throbbing of my cock and then I hear a drawer being opened. "Don't look." Said Sarah.
Not knowing what was happening I kep feeling my balls as ordered.
"Now." Said Emma "get that precum and lick it off your finger."
I swirled my finger round the head of my penis and covered the end of my finger in precum I brought it up to my mouth and licked it of and sucked on my finger. I loved the taste of it and wanted to get some more. "That's it sweet cheeks, now get that hand back between those legs" said Sarah "no, not on your balls. Further back."
I slid my fingers back towards my ass and felt my ass with my fingers.
"Play with your ass hole for us"
Kirsty said "you are in a dress after all"
"You know what your doing back there, you told me you have done it to yourself before" said Sarah "don't worry we all know."
I nervously started playing with my ass slowly running my fingers round my hole enjoying the feeling but no one has seen me do this to myself before. "Get that precum on that ass aswell" said Emma.
It made it nice and slippery I slowly started to put my finger deeper with each circle round my hole.
"That's it finger yourself for us let us know how it feels" ordered Kirsty.
I pushed my finger as deep as I could I started to not care and the sensations where taking over. "That feels good" I moaned.
"That's it now get on your hands and knees" Sarah said as she moved off the bed as I went down on the floor "this will be cold" she squirted some lube on my as "what are you doing?" I asked completely unaware of what was to come next.
"We have another surprise for you" Stacy said, I looked up and both her and Sarah had put strap-ons on and where in their panties while I was fingering myself. Emma also had her phone out taking pictures but I didn't care anymore. Confirming what I was now thinking, Stacy moved in front of me and asked "can you suck it? Like the girl we will make you."
Unsure I said nothing just gave a small nod. As she moved closer and put the strap on in my mouth I felt the other one that Sarah had on slid up and down the crack of my ass.
She poked the head against my ass hole a few times. Then pushed a little harder, I felt the tip pushing in. "Are you ready for me baby?" She asked. I barely got to make a noise and she pulled hard on my hips and slid the end into my ass. It felt so big and I let out a moan in pleasure as it went in.
As it went deeper my cock dripped "look girls he has taken it all" Sarah said.
Stacy removed the strap on from my mouth and had a look. Emma was still taking pictures but I noticed that she was now only wearing her panties too and Kirsty had done the same but she was on the edge of the bed with her hand moving around in them.
Noticing my dripping cock Stacy grabbed it and wiped the precum on her fake cock "now it will taste more like a real one" as she put it back in my mouth.

Sarah got more and more exited to be pounding my ass with her strap on and I was getting close to orgasm. "I need something for me now" Kirsty said moving from the bed and lieing on the floor infront of me now naked "get to licking"
I could see she was soaking wet already so not to disobey I started to lick her soft wet pussy. Almost as soon as I started to lick her I felt the pressure build very quickly inside me. I orgasmed and lost control of my muscles flopping onto the floor "oh my god that was the most intense orgasm of my life." I said weakly.
"We aren't done yet" said Stacy moving in behind me as I lay on the floor "on your back on the bed." She was now naked except her fake cock. "You are dripping wet again."
As I got on the bed Emma now naked aswell straddled me putting her pussy and ass in my face "you know what to do"
I started licking her pussy and she said "that's not all I want. Can't let this dripping cock goto waste" at that she sucked on the head of my cock making sure she got all of my precum. While she was doing that Sarah and Kirsty moved onto the bed aswell Sarah had removed the strap on and they sat at the top of the bed with eyes wide fingers caressing their pussies.
Without warning Stacy shoved her well lubed cock into my ass as Emma took my cock deep into her mouth.
I had to stop licking Emma's pussy as the sensation was overwhelming.
As I rolled my head up with the pleasure I saw Kirsty and sarah now fingering each other and kissing.
It wasn't long before I orgasmed and shot my load into Emma's mouth. Even with my loud moans both of them did not stop I thought I was going to pass out then Emma sat up and said "lick my ass" so with the little energy I had I licked her ass hole while she sat on my face. Pushing my tongue as deep as I could she moaned in pleasure.

Sarah and Kirsty got off the bed and again I heard a drawer openemma got off the bed too. Not moving but keeping her fake cock in my ass Stacy played with my semi to build it back up again.
The girls brought out a few dildos and a larger one aswell. Emma was back to taking pictures of me lieing with a cock in my ass and half spent cock getting caressed.
"We have some more fun for you still" said Kirsty "now that you are all relaxed it's time to take it to the next level."
Stacy removed her cock from my ass and my cock was hard again.
Kirsty sat on the bed and brought the large dildo over. "This is yours. Pull your knees up" she proceeded to lube up the dildo. She pushed the dildo against my ass hole and as before I felt it go in stretching slightly as it went. Compared to the strap on it went deeper I instantly got a more intense feeling that I had never felt before. I looked down and again Emma was taking pictures the other girls where sat on the chairs in the corner watching pushing dildos into their pussies, Stacy was pushing the strap on she had been using on me into her ass.
It was literally a matter of seconds and I came again this time no one was touching my cock but I shot a load of hot cum on my belly. Kirsty scooped it up in her fingers and put them on my lips "taste yourself"
After that I woke up the next morning the girls where still naked toys lieing all over and I was still wearing the dress. They said they had a little more fun then went to bed. I still don't know what happened to those pictures.
