It is a truth universally acknowledged that a single man in possession of a younger Sister usually develops a major crush on one of her friends.

Given that it is universally acknowledged, I wasn’t surprised when Ella came up to me during summer holidays and poked me in the chest.

“I’m having a party this weekend. You’re” Poke “not” Poke “invited.”

I was home from university (fifth year of a three year course – drugs are bad) for the summer and living in the caravan in the back yard. My Sister Ella had just finished high school and was getting ready to head off to the same university to start an Arts degree. Everyone knew she would get better grades than I did.

I put on a hurt face.

“Why would I want to hang out with you and your friends?”

“Because they are all cute, they are all eighteen and we’ll all be very drunk and making bad decisions. But,” she poked me again, “and let me make myself very clear: none of those bad decisions will involve you.”

“Fine, fine,” I said, throwing my hands in the air. The fact that I’m writing this down means that I was obviously wrong at this point. But in my defence, I did plan on staying out of their way, apart from popping in occasionally for a quick perve.

The best laid plans, and all that.

So I stocked up on Coke and snacks and a big bag of weed and I headed out to my caravan for an evening of solo debauchery when I knew it was almost time for her friends to arrive. I had a hard-line installed so I could get online for Porn and I had a small tv and VCR for watching Star Trek. It wasn’t a bad setup.

Ella did the “I’m watching you” hand gesture at me through the picture window. I stuck up my middle finger and grinned as I closed the door.

Lying on the caravan mattress, I heard them arrive.

“Bitches! I am here! Wait, am I the first to arrive? Fuck.”

That was April. She was tall and sporty and brash and insulted everyone in a casual way that left them knowing she didn’t really mean it but actually kind of did. She didn’t like me. I used to tease her about her height because I thought she had the most incredible legs and I know that is toxic masculinity and I’ve been extra nice to her over the past couple of years but the girl holds a grudge. I heard her and Ella talking and hugging and then another voice piped up:

“Drinks! Drinks for everyone! Ella, please tell me you have ice, because I have drinks!”

Marnie had arrived. Shortest of the bunch, bursting with energy, smoked almost as much dope as I did, and loved cotton dresses with nothing underneath (“Gotta be Free, man!”). She liked me fine. I got her weed. I thought she was sexy as hell, but only to look at. She was very intense.

More hugs, clinks of drinks being stuck in ice buckets. Drinks being opened. And another voice. I was up in a second, listening closely.

“You started without me, you contemptuous wenches! Give me a drink!”

I was suddenly smiling, unable to help myself. Catherine had arrived.

I can’t explain what it was that made her the one that I was unable to stop thinking of. I certainly had never made a move, with me at university and her in high school. But I was always drawn to her.

She played the piano. She liked to sing. She was into science fiction and fantasy novels. She was a nerd’s nerd.

And she always looked incredible. No makeup, just huge green eyes, short brown hair, full, always-smiling lips and an impish expression. Her face was sprayed with freckles, as were her shoulder blades. She loved short shorts and long t-shirts and I could never take my eyes off her.

I opened the door and stuck my head out. Catherine saw me and waved, with a warm smile on her face. April noticed as well and scowled, and Marnie caught my eye and made a smoking gesture with her hands, one eye raised in question. I nodded to her – I could provide weed later – and grinned back at Catherine, ignoring April completely. And then I saw Ella’s scowl, and I grimaced and ducked back into the caravan.

More girls, and a number of guys, turned up to the party and soon the place was rocking. People lay chatting on the trampoline and hanging from the lower branches of the huge tree in the back yard and dancing to Hottest 100 tunes on the CD player and smoking and drinking and making out. I peeked at them through the window and watched two of Ella’s classmates making out under the walnut tree – his hand up inside her top and hers stroking him through his shorts. A moment later they were broken apart by a giggling crowd and drawn back into the throng.

I smoked weed and watched Star Trek and rubbed myself and waited for the party to end. By midnight it was winding down and the police had been by to ask them to turn off the music. And then it was just Ella and her core group of friends who were staying the night. And I sighed in relief and stepped out of the caravan amidst a cloud of smoke and eau-de-Me.

The girls were lying on the trampoline in the back yard. It was a warm night and they had a mosquito coil burning underneath the tramp. They chatted quietly and I went inside to grab more to drink and wash up.

When I came back out, Marnie and Catherine jumped off the trampoline and came over to me. Both looked pleasantly inebriated, but Marnie had a glint in her eye and I knew why she was coming over. I patted my pockets.

“Help a girl out?” she asked. I grinned.

“Sounded like a fun night. Did you hook up?” I took her and Catherine both in with my question. Marnie shrugged.

“Sort of,” she said. “A bit of a grope up the back.” She gave her breasts a squeeze to demonstrate. I noticed a couple of buttons were undone on her summer dress. Wonderful curves were showing.

“Nice one.” I turned towards Catherine, hoping the answer would be no. She blushed slightly.

“I was here to relax,” she said. “Trying to get someone’s interest just isn’t that relaxing.”

“I can’t imagine you would have to try,” I said, and her blush deepened. Marnie nudged me.

“Oy, none of that,” she said. “Ella’s watching.” I looked over at the tramp and saw Ella scowling. I shrugged.

“Gotta get you your weed,” I said. I found the bag and pulled out a bunch for her. She slipped it into her own bag and gave me a hug in thanks.

“You better disappear now, before she sets April on you,” she whispered in my ear. I patted her butt as she headed back to the trampoline, holding the weed aloft. Catherine returned more slowly, looking back at me as I went back to the van.

Lying in the van, wearing just my boxers in the heat, I remembered that hug and reflected that each and every one of them was now over eighteen. This was obvious with Marnie. Less so with Catherine, especially with those freckles, but they had all gained a certain confidence over this past year.

I gently pushed at the caravan window next to my bed so that I could eavesdrop on their post-party conversation. My hand was already slipping down inside my boxers.

“That was a great night, Ell,” Catherine said. “A good send-off for high school.”

“Nobody died, I call it a win,” April added.

“When nobody ends up dead or pregnant you have a good party.”

“No guarantees that nobody got preggers,” April said. “Did you see those two over by the tree?”

“That’s why I don’t let people inside the house,” Ella said.

“Didn’t stop them,” Marnie said. “Or me.”

There was a surprised giggle from the others.

“What?”

“Yeah, dunno her name, but she wanted to feel these beauties.”

My cock twitched. It was another girl?

“Oh wow,” April breathed. “Does that mean, you’re, what? A lesbian?”

“God no,” Marnie scoffed. “I am all about the D. But if a girl wants a nibble, who am I to say no?”

“They are very nice boobs,” April said. “Not like mine.”

“Don’t sell yourself short,” Marnie said. “These feel pretty good too.” There was a squeal from the others and they all laughed. Marnie must have gotten a handful of April’s smaller but beautifully shaped breasts.

“Fuck this,” I muttered, and turned off my light so that I could slide the curtains aside and see what was going on. My hand was wrapped around my shaft by now. It had been a slow year.

On the trampoline, Marnie hadn’t removed her hand from April’s chest. It wasn’t easy to see in the dim light from the spotlight shining into the yard, but April wasn’t complaining and had raised her own hand to undo a couple more buttons on Marnie’s dress.

“How about we have a look then?” she asked. “Get the others to vote?” Her fingers paused on the last button. My cock throbbed in my fist. Marnie squeezed April’s breast and then nodded.

“Sure, let’s do it.”

“What?” Ella asked, but Catherine was already nodding.

“OK,” said Marnie, sliding her hand under April’s crop top and lifting the material. “We’ll have to get all this clothing out of the way.”

“We’re in the back yard!’ Ella hissed.

“Everyone’s asleep,” Marnie said, motioning for April to lose the top. April gave a nervous look around and then shrugged and pulled the top over her head. She wasn’t wearing a bra.

“You have nothing to complain about,” Catherine said to April. “You neither, Marnie,” she said, looking down at Marnie who was on her back on the trampoline, her breasts Free and proud. I moaned with desire. Marnie’s breasts were twice the size of April’s, but both were round, with dark nipples sticking out in the night breeze. Marnie was gently tweezing April’s nipple between her fingers and cupping the breast.

“You need to feel these,” she said to Catherine and Ella. “It’s not a proper competition otherwise.”

“Yup,” April said. “Three tests: touch, sight and taste.”

“Are we forgoing the motorboat test?” Marnie asked.

“The motorboat test?” Ella asked, still looking around nervously. She needn’t have worried. Apart from her pervert brother, the rest of the family were up in Echuca for the weekend.

“The motorboat test,” Marnie repeated, and pulled a laughing April down on top of her, pressing her face between April’s breasts and going brm-brm-BRM-BRM-brm-mmm-mmm-mmm. April shrieked and tried half-heartedly to pull Free. Marnie finally let her go after giving each nipple a solid lick.

“April’s winning for me,” she said. April was flushed with arousal and casually flicked her own nipples, rubbing Marnie’s saliva over her fingers.

“I feel like a winner,” she said. “But don’t we need to return the favour?” With that, she leaned over and took Marnie’s nipple in her mouth, sucking gently. Marnie moaned and arched her back, one hand running down over her thigh. She was lying in such a way to show me clearly that there was nothing under that dress.

I’ll admit, that was too much for me. I came hard, spraying against the wall of the caravan. But I knew I wasn’t even close to being done, and neither were they.

Marnie was looking over at Ella and Catherine. “Impartial observer’s time.” She cupped her breasts. “Ella?”

Ella took a hesitant step forward. She reached out her hand. I hesitated. But figured I was really looking at Marnie, and could look away if they started to get Ella’s breasts out. My Sister‘s hand brushed over Marnie’s curves and she gave a gentle squeeze. April hopped off the trampoline and moved in beside Ella.

“Mine too,” she said. “Test them together.”

And then I was watching my Sister with a hand on two different women’s breasts, cupping them and squeezing them. She was deep in thought, sliding her thumbs over the nipples. Her test subjects wriggled, enjoying the touch. Grinning, Ella moved to the other breast of each girl.

“Got to be thorough.” She tweaked each of them. April had her hand on Ella’s hip and was gently stroking her side. Marnie was stroking her own thighs, giving me a great view between her legs.

“I’m feeling left out,” Catherine said. She hopped up so that she was sitting on the trampoline and took Marnie’s Free boob in her hand. “Oh. Oh wow.” And just like that, I was hard again.

April pulled Ella’s mouth down to her breast.

“Taste test time.” Ella took her hand away from Marnie and concentrated on sucking on April’s nipples, her hands roaming over April’s bare back and down to that incredible Ass.

Catherine took Ella’s place, falling back onto the trampoline and bouncing a couple of times before rolling over to cuddle Marnie and kiss her way from Marnie’s neck down to her breasts.

And I watched it all, stroking furiously, wondering at the sexy women exploring each other, maybe for the first time, out on my trampoline in the middle of the night.

The final result came in with April winning the taste test (“They taste like strawberries!”) and Marnie taking out the touch test (“I could play with them all day!”). But the visual element came out a draw, and they agreed that all breasts were good breasts.

“Now onto to the Pussy taste test,” Marnie said, slowly spreading her legs. The other girls giggled, but none of them felt that adventurous, and Ella suggested that they should head inside and make up the beds.

They hopped up slowly, and headed in. Marnie was the last one left. I clearly heard her sigh with disappointment, and slid a finger between her lips, stroking gently up and down a couple of times. I was so entranced, I didn’t realise for a moment that the entire time she was doing this, she was looking straight at the caravan window and the dark patch that was me looking out at her.

I jerked, meeting her gaze and came again, leaving another spray on the caravan wall. Marnie either saw the movement or guessed, because her smile was wicked as she scooted forward off the tramp and walked to the house, barefoot, breasts Free in the night, peeking back at the caravan and blowing me a kiss as she entered the house.

I slept well that night, exhausted from my voyeuristic ministrations. I slept late, and the girls did too, as I was the first one in the kitchen. I was wearing my boxers and a Hawaiian shirt open due to the already scorching heat of summer. Our house wasn’t airconditioned, but the cooler built into the wall still made inside more bearable than my caravan.

“Morning!” came a sleepy yawn from behind me. I looked over my shoulder and smiled at Catherine as she came through the door. She was wearing a long t-shirt and as she moved, I couldn’t see any lines from bra or panties. So maybe just the shirt.

“Morning to you too,” I said. “How did the party go?”

“Oh you know,” she said. “Pillow fights, bouncing on the bed, the basic teenage stereotypes. We didn’t keep you up?”

“I was up for awhile,” I said with a grin, “But I slept like the dead.”

She looked at me for a moment, head slightly tilted, trying to figure out if anything I said had a double meaning. And then she shook her head and went to sit at the table, one gorgeous leg crossed over the other.

“Coffee?” she asked.

“We’ve even got Nescafe Blend 43,” I replied. She winced, but nodded resignedly.

“Beggars can’t be choosers.”

“I’ll run out later and get proper coffee for everyone,” I promised. Her eyes lit up. I brought her a glass of orange juice while the kettle boiled. Her smile woke me up even more. I saw her gaze catch on my chest and stomach as I turned away again. She stood up. Wandered into the lounge. I heard tentative plinks from the piano. And then she started to pick out some simple melodies.

I brought her coffee and questioned her with a glance downwards as to whether I could join her. She nodded and I sat down. I started to play a baseline while she continued to play the melody. Our arms touched with every movement and her hip was pressed against mine. I glanced down and saw that her t-shirt had ridden up as she sat down and now only barely covered her. If she’d glanced down, she would have noticed a clear bulge in my boxer shorts. She caught my eye and smiled, picking up the pace on her tune. I changed tempo to match her. She pressed her leg against mine and this time she did glance down. Her smile when she caught my eyes again was that familiar impish grin that had me so infatuated. I felt her leg move and took another glance downwards. She was shifting back and forward on the piano stool, slowly working her t-shirt higher up her body. A tuft of hair was visible between her legs. My cock strained inside my boxers, and I figured – well, if she can do it, so can I.

With both hands on the piano, I started to shift my hips, and my cockhead dragged along the cotton of my boxers, working slowly towards the button fly, which never really held anything in. Catherine gasped, and her melody struck an off note as she saw the purple head peak out above the button. Precum glistened at the tip – I was so incredibly Horny. She wriggled forward again.

“What the fuck do you think you’re doing?” growled Ella, storming through from the kitchen. We both stopped playing and I quickly turned away from her to readjust my boxers. Catherine swivelled off the stool and stood, grabbing her coffee.

“Just a bit of piano practise,” she said. The pinkness of her face could be explained away by the heat, but Ella looked suspicious.

“Don’t drink that shit,” Ella said, pointing at the coffee, “I’ll go get us some real stuff.”

“Don’t worry, Sis,” I said, standing up, still facing away from her. “I’ll get them. Write a list while I get some pants on.”

“Maybe you should come into the house wearing pants next time,” grumbled my Sister. Don’t get me wrong, I usually loved her dearly, but this ‘hands off my friends’ lark was getting to me.

“I could be wandering around naked, so this is a step up.” I winked at Catherine and headed out to the van to grab my keys and some pants.

***

I stayed away until the evening when I was graciously invited to join them for dinner. The four girls had been out shopping and had plans to spend the evening modelling clothes for each other. I was obviously not invited to this session either.

Feeling decidedly grumpy, I headed back out to my van, stripped down to my boxers and lay down to watch TV. I fell asleep almost immediately.

The door to the caravan opening woke me, but not enough that I bothered to move. I was lying on my back and I think I may have been dreaming about Catherine because my cock was as hard as a rock and jutting upwards inside my boxers. I let my eyes slip open just a crack – not enough to give the game away but enough to see who was coming in.

It was Marnie. She opened the door carefully and then stuck her head in, checking my face to see if I was awake. And then her mouth opened as she saw the pole flying at full mast. She stared for a good moment, and then looked quickly back over her shoulder. She gestured to someone behind her and after a moment April stuck her head around the door. Marnie pointed. April gasped. The two of them backed out of the van and closed the door most of the way. I heard them giggling and whispering.

“Oh my God. That is impressive!”

“Quite a tool to come out of that tool.”

“Come on, he’s not that bad. He gives us weed.”

“He gives you weed. He called me a weed.”

“But not for ages. Anyway, he’s asleep now. I came here to find his stash, but maybe we can find something else to puff on.”

“You can’t be serious. It’s Ella’s brother!”

“Who cares? Her and Cath are asleep. It’s a very hard cock is what it is, and after you guys stood me up last night, I really need to get off.”

“Did you really want to?”

“I mean, only if you wanted to, but no, I was joking. Kind of. But I really want this.”

“So what, you’re just going to go in there and jump on?”

“I mean, I might have a nibble first, but yeah, that’s the plan.”

My cock was throbbing. Please let this happen, I prayed. I will stop copying PlayStation games from the video store. I will mow the lawns without being asked. Just let me have this.

“You’re crazy. What if he says no?”

“He won’t. I saw him watching us last night.”

“He what??”

“Shhh. I’m sure he had a good wank. Well, now it’s time for us to have a turn.”
