Waking up hard is not that unusual for me, Tom, but this was different for some reason. As I woke, I realised that it was because Sam was lying on me, eliciting a reaction.

Sensing my [general] awakening, she said, "Morning," and kissed me. I returned the kiss and we started gently making out with our sleepy tongues exploring each others' mouths. As we made out, her wet pussy was gently sliding over my hard and growing cock and then with one motion she slid my hard cock into her and started moving up and down on it.

A few minutes later, she pulled her mouth away from me, so I could see her gorgeous bust hanging down and said, "Any plans?"

I'd planned to go to Peninsula Park for a long run as Sam likes running.

I said, "Get dressed, breakfast, go to Peninsula Park for a two-hour run. You?"

Sam said, "Nice idea .. slightly wrong order. I'd planned to spend today with Kate [flatmate]. Maybe the three of us can go and run together?" Normally, having a group run is good fun, but I suggested to her that maybe we wouldn't only run and I started kissing her breasts. She got the hint, kissed me and ground harder on my cock. I said that we could do a two-hour run which had a short coast hop via some small beaches where we could consider a rest stop. She nodded, wondering if "rest" meant that, or our definition of an intermission!

We decided to get up and make breakfast and lunch for the trip, but she said, "Dress later," so we went into the kitchen naked. We stood in the doorway making out for a few minutes. Our kisses were getting more passionate as Sam's hands were stroking my cock and mine were rubbing her wet pussy. We then pulled away as our stomachs were overriding our loins and made the food.

We set the table and, like dinner, I sat down on the chair. She straddled me with her bust at my mouth level. I grabbed some pineapple and traced it over her bust, then licked the juice off her nipples which were growing bigger and harder. She moved down onto my glans and stared full-tongue kissing me as she slid up and down my head. I kept my hands on her bust, massaging them and her nipples as she fucked me. Our tongues were probing deeper into each others' mouths as her wet pussy moved faster up and down me.

I lifted her off me and guided her to the wall. I inserted my cock into her pussy and she tightened on me immediately. We started kissing again and she said, "Fuck me harder NOW."

I thrust harder as she was squeezing me until I came, which caused her to shudder as she came on me.

Sam said, "Eat," and guided me by the cock back to the chair. I sat down on the chair and she guided herself onto my tired cock. We sat there for a while feeding each other and periodically kissing.

We then put the dishes in the dishwasher and moved to the bedroom where we'd put our clothes last night. We had a quick make-out then I put on another tri top and undershorts with Sam putting yesterday's gear back on. She said I was untidy and her hand reached down into my shorts and arranged my cock. I thought she had one breast misaligned, so I reached under her bra and rearranged things. I said that we'd be here, naked if we didn't stop, so she grabbed my overshorts for me.

We then drove my car to her car and I followed her to her flat so she could get changed. Kate, her flatmate called out "hi guys" as Sam opened the door. I came over and gave Kate a quick hug as we'd met at The Dog and she said, "so you're bed buddies now?" - it was obvious that Sam had called Kate in the car! Sam said, "Not sure .. we haven't really tried that yet!" I suggested that we were running friends that enjoyed a few other activities. They started laughing together.

Sam went into her room to get changed: I thought that if I followed, we wouldn't be running today. As Kate and I caught up about her work, Sam appeared at the bedroom door wearing a different sports bra - this time a back-zip one that showed a bit more bust than the front-zip one and some new shorts and said, "How's that?" I nodded and my cock hardened. She dived back into her room, returning now wearing an over-vest and over-shorts which we'd need for the run and with a leopard-print bra and panties set in hand- the bra would have been good for Kendall Jenner, but would barely support her bust - maybe that wasn't the point of them I thought?. Sam said, "These are for later."

Kate said, "That's why I'm not coming then!"

We drove to the park and put on our running packs as we were going to need some water on the run. We had a quick make-out to re-acquaint ourselves, then started off the trails. Over the next hour, we mostly ran and talked about life and just getting to know each other - rather than getting to know the other's body like we'd mostly done so far, but occasionally found the time for a short make-out and "re-position."

We got down to the beach where I suggested we could coast run to the next bay and then relax. The tide was higher than I had hoped for, so we agreed that we'd walk-swim it instead which was new for her, but I'd done coasteering before. We took off our overshorts and she took off her overvest, exposing her bra and the hint of bust. I kissed her and we started grinding and making out until we were sated. We started running along the beach until it got too deep, and then we swam out around the head to a new bay.

In the new bay, the sea floor started shelving up and we started walking again - now fully wet. Her top was clinging to her bust - more so than the previous top, I thought. I turned around and put my hand around her neck and kissed her. She responded by opening her mouth so my tongue could probe. We started Frenching again as my hands moved down and into her bra: as I thought, her nipples had gone hard again. Sam's hands dove down and undid my drawstring, then started working her magic on my cock.

I saw a smooth rock on the cliff and guided her to it. Sam said, "I've seen it in the movies where people fuck against a cliff, but I've never done it. Have you?" The few adult beach hookups I had, we had screwed either in the sand or the water, so I said, "No - first time too." I guided her against the rock and started kissing again. As there was nowhere to get undressed, I lifted her top over her tits and started sucking them. By now, she had dropped her shorts to her shoes and guided my cock to her pussy. This was a different experience as our movement was restricted - wearing packs and our shorts being around our ankles.

Our tongues started exploring each other's mouths as my hand started exploring Sam's pussy; her hand was working its magic on my cock. By now our kisses were definitely in the "why aren't you inside me?" mode, so I obliged and slid into Sam. Our kisses became more passionate as my cock reached deeper into Sam and my hands grabbed her tits harder. Soon, I could feel Sam's pussy squeezing me hard as she started pulsating. This was my trigger to cum too.

After a few minutes of post-sex kissing and fondling with Sam still against the rock and my rock inside Sam's cave, we decided to get dressed and finish our run. I helped Sam put her bra back over her bust and diligently made sure that the bra was doing its job properly, then Sam reached down and brought my shorts up and made sure my cock was in its right place.

Sam said, "I wonder what the picnic will be like?"

I said that with the leopard print that she'd shown me earlier set on her, it wasn't just the food that was going to be eaten.
