********************************
I awoke early the next morning, shortly after sunrise; I have always been an early riser. I looked over at Ann, sleeping peacefully on the bed next to me. Her blonde hair spread across the pillow, the sheet only covering her to the waist. I could feel myself harden at the sight of her breasts and the beautiful pink nipples at the tips; memories of our evening vivid in my mind. I walked down the passage to the bathroom and had my morning pee. washing my hands and face and felt a bit more awake. I headed back down the passage in search of the kitchen and my first cup of coffee for the morning.
As I walked through the lounge I could see that Rob and Sue had clearly started their seduction in the lounge and progressed to his room. Their clothes were strewn carelessly across the furniture and floor. I continued to the kitchen, filled the kettle and turned it on. To kill some time, I wandered back into the lounge and started to tidy up, throwing all the items of clothing onto the armchair in the corner. I could see Sue's clothes piled together and as I picked up the pile of clothing her cream coloured bra fell to the floor. I looked at the tag "34C" it read, somewhat bigger than Ann's "A" cup. I realised that I had been a little slow on the uptake and started to rummage through the clothes until I found her panties. They were the same cream colour as her bra. Simple cotton fabric with a wide gusset, they were a little bigger than Ann's. I flipped them over in my hands to inspect the gusset more carefully and was happy to see that they were still a wet and heavily coated with her juices. Rob's attentions had certainly got her aroused. I inspected them a little closer and saw that a few of her hairs were stuck in the juice. I raised her panties to my nose and inhaled her most personal scent. She smelt so good; a hint of pee, but mostly the fantastic scent of her pussy. I was once again rock hard. Before I could continue I heard the kettle boiling in the kitchen. Taking her panties with me I walked back to the kitchen and made my morning coffee. I was in two minds whether to pull on a pair of shorts but decided against it. The cabin was so remote, the only possibility of being seen, would be from passing boats and my fellow house mates were unlikely to surface soon.
I opened the door out onto the balcony and sat down, put my coffee cup on the armrest and went back to inspecting her panties. I raised them to my nose and breathed in her scent once again. I took my cock in hand and started to slowly stroke myself, while sniffing and licking at the gusset of her panties. These had been snuggled up to her pussy less than 8 hours earlier and the thought of sniffing her pussy was very erotic to me. The fact that she didn't know, made it even more so. It didn't take too many strokes until I was shooting my cum into the air, splashing down onto the unvarnished wooden deck at my feet. I milked each drop out, letting it drip at my feet. As I softened I dropped the panties on the chair next to me and sipped my coffee. I watched as the last drops of cum oozed from the tip of my cock onto the deck below.
Time passed faster than I expected and my peaceful state was soon disturbed by the sound of a toilet flushing. I stood quickly and tucked the panties under the cushion of the deckchair and picked up a towel over the railing. I picked up a towel that had been left over the railing and mopped up the cum at my feet, as best I could. Most of it having soaked into the wood, leaving a wet stain on the deck. I walked back inside in time to see Ann walking into the kitchen. She had wrapped a towel around herself; it was barely covering her.
"Good morning beautiful" I said. She walked over to me and gave me a big hug. The wet tip of my stiffening cock brushing her inner thigh.
"Morning, any chance of a cup of coffee. I don't function well without my morning coffee."
I switched the kettle back on and she soon had her coffee in her hand.
"Let's sit on the balcony," I suggested.
"Hadn't you better put some clothes on, Sue might get a fright when she sees you naked?"
"I think after what Sue saw last night she will be beyond any shocks from me." I laughed.
"What makes you say that?"
"I heard them going at it when we went to sleep last night. Rob is well known for being extraordinarily large, so she has seen it all!"
"Either way it may be best to pull on a pair of shorts." she countered.
I sighed and made my way back to the bedroom, pulling on a light pair of sleeping shorts.
When I returned to the deck, Ann was sitting in the chair I had been sitting on earlier. What happened her she asked, pointing at the wet spot on the deck.
"Just some coffee," I answered hoping that she believed me. We were too early in our relationship to admit that I had jerked off using her friend's panties!
We sat in silence for a while, enjoying the solitude of the early morning and the beautiful view overlooking the river. The only sounds we could hear was the chirping of the birds at the river below. Inevitably this peaceful time was disturbed by sounds of Rob and Sue moving inside the cabin. I stood up and went to greet them both. Sue was standing in the kitchen preparing coffee for them both. She was wearing one of robs tee shirts and it barely covered her bum. Her full breasts filled the front of the shirt and her hard nipples were clearly visible.
"Good morning lovebirds." I said cheerily. I saw Sue blush at my comment. "Sleep well?"
"Yeah, not too bad once you guys stopped making so much noise." Answered Rob.
"You guys didn't do a bad job yourselves" I retorted. Sue blushed even more.
I made another cup for Ann and me and headed out to join the others on the deck. Rob was sitting on the rail and doing his best to see under Ann's towel. I gave Ann her coffee and sat on the rail beside Rob. I could see that he had a good view under the tiny towel and it did little to hide her pussy. This was equally true for Sue who was trying, mostly unsuccessfully, to keep the tee shirt covering her lap. As we chatted and the girls became a little more relaxed we soon had a better view of their pretty pussies. I could feel myself hardening and looked over to Rob. His monster cock was on the move and he was trying his best to push it to one side with his forearm, to make it less obvious. My own arousal saved him further embarrassment and I stepped off the rail and took Ann by the arm.
"Let's take first turn at the shower?" I asked. Taking my hand, she stood and we headed back inside to the bathroom.
Ann dropped her towel as soon as I closed the bathroom door. She turned and knelt in front of me, pulling my shorts down my legs, freeing my cock, which by now was standing proudly up. She took me in her hand and guided me into her mouth, giving me a sloppy suck.
"I would rather be inside you," I murmured. I was longing to enjoy her hot pussy once again.
"No complaint from me!" she said, standing to face me. I took her in my arms and we kissed deeply. I could taste my cock on her lips.
I stepped back and sat down on the toilet. As she stood in front of me her pussy was now at head height, inches from my face, and I could see her moisture coating her blonde pussy hairs, matting them untidily. Her lips still swollen and pink. I pulled her gently closer to me until her legs were straddling mine. She lowered her body down until her pussy lips slipped over the tip of my cock, her warmth engulfing me as she pushed down, until I was buried all the way inside her. She clung to my neck as we rocked gently, gaining a steady rhythm. My mouth found one of her nipples and sucked and nibbled at her beautiful nubs. I could feel her movements quicken, grinding herself against my pubic bone, her moans becoming louder and more urgent. I could feel my own climax approaching and speeded up my strokes. I felt her body stiffen and thrust myself deep into her. Her pussy clenching my cock and with a jerk I shot my cum deep into her. We didn't move for a while. We just kissed each other lovingly, our tongues dancing in each other's mouths. We eventually broke our embrace and with shaky legs she slowly stood up, allowing my cock to slip from her, it was followed by a flow of our juices; down my cock and onto my thighs. I cleaned up with some toilet paper and stood up. She turned the shower on.
"Let's get cleaned up." She said stepping into the shower.
Once we had showered we dried off and headed through to our room. I found a pair of board shorts and forgoing underwear pulled them on while Ann rummaged through her bag until she found her bikini. As she was putting it on I was very surprised at how small it was. No complaint, just unusual for those days. I wondered whether Sue would be as brave?
