I’m not a voyeur.  No, really, I’m not, but when fate drops something into your lap, as it were, I would be a cold fish to walk away, don’t you think?

Quick backstory.  It was my final year at University, and I was in a house-share with another male and three females.  We all got along well with each other and lived separate existences as we studied different subjects.

One weekend, both Alan and I had planned to be away visiting family and he duly disappeared on the Friday evening.  I left early on Saturday but arrived home to find that my folks had gone away for the weekend and forgotten to tell me.

I could have chilled at home but saw an opportunity to finish my assignment early for the first time in my three years of study.  Sunday was going to be a slog but hey!

When I got back, I gave no thought to who might be there.  I knew Alan was away, but the girls could be up to anything, and indeed they were as I was soon to discover.  Enter the unpractised voyeur.

I climbed the stairs towards my room, and along the short landing that had a window facing the living room.  To my delight and amazement, I spotted the three girls, Suzie, Linda and Zoe in their PJs, watching what looked like a lesbian porn movie.  Wow!

Feeling rather flustered, I continued to my room, dumped my bag and wondered what to do next.  OK, I guess there wouldn’t be a story if I’d started work on my essay, but it was touch-and-go.

Creeping back to the window and the convenient chair (I always wondered why that was there), I watched the porn movie with some delight – two girls having sex on the screen, and three others beginning to get antsy as they watched.

I forgot the TV.  The first girl to take positive action to what they were watching was Zoe.  I suspect she was hoping no-one would notice as her hand slipped inside her PJ bottoms and with an almost imperceptible movement responded in the best way she could to the unfolding scene on the TV.

I just spotted Suzie take a quick glance at Zoe and, pretending not to have noticed, did the same thing.  I could just hear their voices and it wasn’t long before Linda said, “You’re not very subtle, you two, I could smell what was going on without looking!”

Standing up, she dropped her PJs and plonked back down again and took much more positive action than the other two, vigorously working her clit and alternating with two fingers plunged into what must have been a sopping pussy.

“Dirty bitch,” retorted Zoe, as she too dropped her PJs but then proceeded to take her top off as well.

Not to be outdone, Linda did the same, but then put her hand under the sofa and pulled out a large vibrator and started fucking herself vigorously and between gasps, challenged the others with, “Now who’s a dirty bitch.”

Had I been studying human sexuality, I might have watched this scene with academic interest, but engineering hadn’t prepared me for this and I realised I had released my cock from its very uncomfortable confines and was gently stroking it as the three girls had their fun.

I knew they all had boyfriends and indeed had heard them often enough making good use of the features on offer, but no mention had ever been made that any of them were into girls as well.  I can assure you they were.

Linda had the advantage and after pumping her pussy with the dildo whilst spewing the filthiest of language to her friends, she came in a shuddering climax that seemed to go on and on – the most beautiful sight I had seen in my 21 years on this planet.  Could it get better?

While Linda recovered, Suzie grabbed the vibrator and I could hear it buzz as she said to Zoe, “On your knees, girl, your turn."

I had never seen Zoe move so fast and with her glorious arse staring me straight in the face, she was in the ready position as Suzie weaved her magic.  The dildo plundered that pussy is the most delicious way and I could see how wet it was from my hiding place.  “Buzz,” “Silence,” “Buzz,” “Silence,” in and out it went, and as Zoe moved towards her own orgasm, I watched in awe and wonder as Suzie’s index finger went first into her mouth for lubrication before slipping into Zoe’s perfect backside.

I was dying to call out, “Spillage in aisle three,” but managed to contain myself as I gawped at the amazing vision of a beautiful girl with a beautiful arse having an orgasm, the like of which I could only dream, with her ejaculate spilling all over the parquet floor.  Practice, I thought, I need more practice.

Now we had two girls in a collapsed heap; what could Suzie possibly do to match that.  Holding the twice-used vibe (not on furlough that one), she swung round so that her legs were over the back of the sofa and she lay between the other two girls and said, “You two are so, so beautiful when you’ve just come.  Stay like that while I do the same.”

With that, she turned up the vibrator to its maximum and without any movement, held it against her clit as she stared, as if in love, into the eyes of her housemates, switching between the two.

It wasn’t long before she came too, but hers were a series of body-shocks and I could see her eyes roll into the back of head as she stuttered, “OMG, I’ve never been this horny before.”

All three in a heap of satiation, revelling in their post-orgasmic bliss?  Not a bit of it.

“You filthy pervert,” Suzie yelled and rocketed out of the room, closely followed by the other two.  I cut and ran but was too slow to lock my door as three naked girls surrounded me.

“What the fuck were you doing?” one of them said.

“Watching the most beautiful sight of my life,” I somewhat hopefully replied, and thankfully they all giggled, but it wasn’t over yet.

“Punishment time,” the effervescent Zoe declared, and they dragged me back into the living room with me in stunned silence.

Linda appeared from somewhere holding some shackles.  “OK,” she snorted at the other two, “Pete and I enjoy a bit of this sometimes, don’t judge.”

Before I knew it, they had stripped me of my clothes, revealing what can only be described as a visible sign of the thoughts in my head.  Shackling me, wrists and ankles, to various immovable pieces of furniture, they had me on my front and, given my condition, it was extremely uncomfortable.

They had made no effort to cover up, which was some sort of blessing, but even that thought was short-lived as Suzie had removed my belt from the pile of clothing and let rip with a mighty thwack at my bare bottom.  I just had time to think what a glorious sound leather on arse makes, before the intense pain ripped through me.

Determined to be alpha male about this, I did at least allow myself a sharp intake of breath, before the second unconstrained infliction arrived.  Teeth-gritting time.

“I want a go,” Zoe and Linda yelped in delighted chorus, and so it was, two more lashes with the leather belt arrived to the thrill of the girls, and, ok, yes, I was harder than I had ever been and was half horrified and half excited about what I had discovered about myself that evening.

Relieved it was over, I was all ready to make one more apology before going to bed and tending my wounds, when Zoe wrapped a blindfold round my eyes while the other two rolled me over and re-fixed the shackles.

A word of advice.  If you’ve just been beaten with a leather strap, don’t lie or sit on your bottom for at least twenty-four hours.  Ah well.  I grimaced, repeated my now rather repetitive intake of breath, and waited for more pain.

Theologically speaking, I had started in paradise, watching these girls at play, gone straight to hell as they wreaked their revenge on me, but for some reason, I was about to be released from hell and sent straight to heaven.

I could hear the girls at the end of the room whispering amongst themselves and heard them coming back to me, so I felt some trepidation.

The forthright Suzie spoke for the gang.  “There are three of us and only your cock and your mouth to work with.  So, we are going to take it in turns, and you will not be released until you have made each of us cum, one way or another.  If you cum too soon, then we will wait and fill the time with your gorgeous leather belt.  So, don’t.  When we have all cum, we will release you and you can choose one girl to do whatever you want with, within normal limits.”

At this point, I was really grateful for the pain I was suffering on my backside as it helped me think about other things.

I had no idea what order the girls would take their turns, but I was grateful for the orgasm I’d had watching them from the landing (damn, I meant to keep the sneaky wank quiet!) as it would help me see through this experience.

Before I could think about what might happen, one of the girls sank onto my aching, throbbing cock, while a second knelt over my face and lowered her highly aroused pussy onto my mouth.

Torture?  You’ve got to be kidding me.  I have never before or since been so wound up sexually.  My bum ached, my cock was in blissful full employment and I was savouring the nectar oozing from a pussy that had been made for sex – tasty juices and an easily located clit for my special attention.

I licked and nibble and swirled and sucked and blew and could tell that keeping this up would not only be one down and two to go but would help me ignore the delights of a pounding pussy down below.

As predicted, girl one came in a shattering orgasm from my tongue-lashing and from the guttural noises, I realised it was Linda.

The girl on my cock switched and sat on my face and girl three sank with ease onto my cock, soaked from its previous owner.

My tongue was aching now and keeping up was a challenge, but I did my best and although we never quite got there, she was clearly enjoying it and I marked her down as Zoe.

Meanwhile, girl three, who must have been Suzie, was riding me reverse cowgirl and this was, by all accounts, hitting the right spot for her as it wasn’t long before this whole crazy situation as well as watching the others girls fuck me, proved too much for her and I could feel her muscles contract over and over as her orgasm hit.  I loved it and was so proud I was staying my ground.

To my relief, Zoe announced, “Come on girls, the guy has done really well, and I’d like to do a deal.  As I haven’t cum yet … well, since the porn film… and I’d like to let him go, provided his free choice is with me.  If he wants one of you two, so be it, but he must make me cum first.”

Thinking back to the vision of Zoe bent over on the floor being seen to with the vibrator is something I will never forget so I would have chosen Zoe anyway.

“It’ll be a pleasure,” I said, thinking it was most sincere thing I had said in my life, and I was duly released from my bondage.

I had never been more ready to cum, but this was something to be savoured.

“I’d like you to enjoy this, Zoe,” I said, “so let’s take our time.  Firstly, please rub some soothing cream into my backside so I can focus on you and not my arse.”

Zoe tripped away to her room and I watched in wonder at the vision of her backside disappearing; so smackable, but that would be for another day.

She soon returned and I lay on the sofa while she worked the cream into the red weals on my arse.  Bliss.

Thanking her, I offered to use the cream to massage her and the whole tempo of the evening slowed from frantic sex to a beautiful erotic calm.  The two other girls were transfixed by this change in atmosphere and were sitting in the two armchairs just very gently rubbing their pussies as they watched.

I took my time, spending extra care on her ample bosom (I love that phrase) and her prize-winning bottom.

Whispering, so the other girls wouldn’t hear, I asked if she like anal sex, and her eyes lit up like a fireworks display.

I held out my hand like a gentleman and helped her to her feet and led her round to the back of the sofa and bent her over, so she was supported but with her bottom open and inviting.

My erection that had subsided somewhat while I gave the massage, returned to full-service duty at the sight before me and I started slowly by fucking her pussy to get lubed up for the real deal.  I could feel the preparation time and care I’d given her had made her so horny, that there was a risk she might come too soon.

Her choice.  “Do you want to come now and then in the arse?” I asked, “Oh yes, she gurgled, if you don’t give me at least two orgasms, I’ll bloody well have to do it myself.”

I increased my pace and could feel that wonderful sensation of a woman responding in my arms, my hand on her boobs as she panted and moaned and came deliciously.

Without letting her pause to recover, I slipped my dripping cock from her pussy and eased it into her backside.

Her noises were beyond description here but believe me, they were of pure sex.  Slowly, slowly, back and forth, I worked my way into the forbidden zone, and with each increment, she let out more of her extraordinary noises.

I glanced at the other two girls and realised they couldn’t see the action from the armchairs, and they had come round behind sofa and were standing really close to watch in detail.

This was too much for me, my time had come.  I was now buried deep inside Zoe and started to ease back and forth, increasing the pace as I did.

Zoe was heading for another orgasm, and I checked the other girls could see what was happening and saw them both masturbating vigorously as they watched.

“Tell me when you’re coming Zoe, and you two hold back until she does.”

“Oh God, now,” she gurgled, “I’m coming now and it’s so fucking good.”

Her contractions began and I swore as I unloaded myself deep inside her, deafened by the sound of Linda and Suzie shouting that they were coming too.

What an evening and it ended with Linda and Suzie demanding we promise not to tell their boyfriends, and Zoe making an emotional call to break off with hers.  He had apparently been disappointing her in many ways for quite a while.

Zoe and I shared a bed for the first time that night, and so far, ever since.
