I wasn't expecting it at all but when a friend request appeared from Lisa I didn't hesitate to accept it. Ten minutes went by before my messenger popped up with a generic "hi." I replied the same and after a brief and polite exchange with the girl who had pissed on me two weeks ago, another bike ride was organized.

Anticipation was high by the time I jumped on my bike and took the five-minute ride to Lisa's house, I was struggling to keep things under control in those tight lycra pants so fashionable in the cycling world as Lisa greeted me at her door.

The exchanges were so very normal, so very friendly, it was as if two friends were meeting again and in many ways, this was correct. Except Lisa had pissed on me!

We took the same ride as before and once again I'd managed to ride behind her so I could take in the view of her ample arse and see her obvious panty lines beneath those cycling tights. Lisa had her gilet on, but that struggled to hide her curves. As I rode I tried in my head to decide if she was a D cup. I doubted she was an E but the mind game was entertaining as I watched those cheeks and wondered if or when she was going to soak me again.

All the time I was mentally going through all the potential connotations of the day I noticed every time she drank from her water bottle knowing that at some time, it had to be released. The thought occurred to me that I was becoming obsessed, obsessed with Lisa's hot wet piss. I wanted it, I wanted her and I was hoping she didn't know that (I think).

We'd been riding at a fair pace and the temperature was fair so sweat was an issue as we took our first stop. Lisa had stopped at the bench, the very same bench where she had straddled me and pissed on me.

"Weather's better today, no chance of rain." She said, catching her breath before sitting down, unzipping her gilet to reveal a tight top, body-hugging her ample tits.

I was struggling with this, struggling to understand her complete lack of reference to our previous experience. How can you piss on someone and seemingly ignore it? To me, it made no sense as I sat next to her and commented, in an effort to bring the subject up, that it was unlikely to be as wet as last time.

Lisa smiled "I don't know, we've still got a way to go yet."

She stood up and bent over as if to tie her lace, her arse was in full view as I studied closely those panty lines and told myself she was doing this on purpose.

She removed her gilet and pushed it into my rucksack. She didn't ask if it was ok, she just did it. Without speaking, she jumped on her bike and rode off leaving me to hurriedly catch up.

Twenty minutes later we arrived at the pub. Lisa sat down on the seats outside, too warm to go indoors. I brought the drinks out to her before sitting opposite her to admire her blond hair and Scandinavian looks.

"Remember Jo, from work, used to be a secretary?" Lisa asked, after a long cooling drink. I asked if it was the same Joanne who looked incredibly young, despite being in her early forties. Lisa smiled before agreeing and confirming it was her.

It was then that Lisa delivered the bomb.

"I mentioned to her that you seemed to like me pissing on you, judging by the effect it had on your cock. She was very curious as she's getting fed up of always dressing like a little school girl for everyone else’s fantasy and fancied trying something a little more dominant. I said I'd ask you if you were in any way interested?" Lisa smiled as she judged my reaction and waited for my reply.

Lisa had me in knots. The casual way in which she referred to this confused me as I stuttered out my obvious agreement to her question.

"Good! I'll let her know."

She put down her empty glass and once again rode off, leaving me to drain my glass and cycle quickly to catch her, my head spinning with the content of the conversation we'd just had.

We returned the same way down the straight river bank until we arrived at "our" bench. Lisa stopped and sat down. It was a boring Tuesday; no-one around and the weather warm. She looked left and right, there was not a soul to be seen.

I was just about to ask her a little bit more about Joanne, like what she wanted, what she'd asked for but I didn’t get the chance before Lisa told me to sit down. Lisa threw her leg over me and straddled me again, just as she had before, her tits inches from my face, her hands clasped together behind my neck.

"You'd better not let me down, with Jo I mean!"

I never had an opportunity to reply before I felt her hot piss soaking into my trousers. Her eyes locked onto mine as she smiled at me. My hands rested on her hips, she was treating me so badly and I loved every minute of it.

She moved closer as she whispered in my ear, "Good boy, I know you like it."

Her hot piss had soaked me and my cock bulged in its tight restraint as Lisa stood up. She looked around, there was no one about.

"Stand up, turn your back to me," she commanded. I, of course, complied as I felt her hot piss soaking into my tight trousers.

A minute or so had passed, I'd heard what sounded like Lisa getting undressed, or was that what I'd hoped? She told me to turn around again and I faced her, fully dressed apart from her sweaty, pissy white knickers she had hanging off her fingertip.

She smiled and stood inches in front of me, lifting her knickers to my face. Her hand stroked my bulging cock through my trousers before she issued her next command, "Open your mouth."

Her hand firmly grasped my cock as my mouth opened, she slid her hand down my trousers as she pushed her knickers into my mouth.

Lisa began wanking my cock, looking at me, smiling as her flavours flooded my mouth. I knew I wasn't going to last very long as her skilled hand worked on my shaft. I reached out to her tits but her other hand slapped me away before it pushed my mouth shut.

The taste of Lisa's sweet wet knickers and her obvious cock handling skills proved too much as I emptied my load in my trousers, on Lisa's hand. She held my gaze, smiling all the time as she milked the last of my cum from me. Her clean hand removed the knickers from my mouth although her taste remained.

She released my cock and presented her cum covered hand to my face.

I knew what I was to do as I shut my eyes and licked my cum off her hand.

I heard Lisa laugh. "Good boy, I don't think you'll disappoint Jo."
