(There's not as much action here as in parts I and III. IV will be VERY action-based, though, no buildup nor denouement, a true one-handed read.)

Glistening in the sun the evidence of our sweat release mingled, the thick whiteness of my forceful release cooling to the temperature of her sweat, her wetness mingling with the traces of lube between her thighs. We were still locked together, her left hand wrapped around my now-limp potence, my hand gently toying the entrance of her ass, a non-comital tease. I don’t know how long we would have stayed locked like that, but Geoff broke the silence.

“Right, we ought to clean up. You made quite a mess of her Ian.”

I stared to speak but he stopped me.

“Not that there’s anything wrong with that. We just might all feel a little better if we clean up.”

He passed a wet cloth to Tess, and another to me. As she began to wipe the thick spurts of cum from his shrinking erecting I slid the cool, wet cloth between her legs. Wiping the lube from betwixt her buttocks brought them into a clench, and only as she relaxed could I move forward to attend to her womanhood, wiping her wetness from her thighs and the traces of my tongue from her piercing and now-hidden clit. Slowly crossing the lengths of her flat stomach I wiped myself from her navel, from her chest and small sensual breasts, before my hand crossed her throat, removing the record of my passage there as well before taking the first and final drops of my release from her chin. Her hands went to remove Geoff’s offering from her bum, seemingly reminding him of the drop of precum he had left me with.

“Sorry mate, didn’t mean to get you with the friendly fire.” He said as he passed the cool, damp fabric across my tensed ass. “Let me make it up to you.”

When the coolness of the cloth hit my post-orgasmic glans it was like a wave braking, pulling me deeply under its pleasure. I shivered slightly under the sub-orgasmic pleasure.

“I didn’t know you were both going to take care of me.”

“I’m not, just trying to help you clean up, since Tess won’t.”

“I would too! If SOMEONE hadn’t insisted on cumming on my bum I would have already cleaned him. With my mouth.”

“Maybe you should have waited a minute, Geoff."

“I wouldn’t worry, you can get cum in her mouth another time. Usually I wouldn’t handle another man like that, so enjoy the rarer pleasure.”

They knew I was bi, but this was the first it had been mentioned. I felt a slight discomfort. We were almost strangers…

“You didn’t have to or anything…”

“I know, look it wasn’t anything like that. I just meant, you’ll be in her mouth again. I might only owe you that favor once, so let me do it.”

His tone was softly apologetic, and now I felt bad for being snippy. He WAS cleaning my balls.

“Alright, I didn’t mean anything and neither did you. Thanks for cleaning me, we DID make a mess.”

He smiled, then drew away. Tess spoke.

“I still feel horny but I’m afraid you two have been drained.”

“That’s the first thing you’re thinking? More?”

“Yea. She’s insatiable mate.”

“I want to have one or the other of you. Properly.”

“Just now?” I asked

“In a few minutes. I don’t expect instant recovery, especially not from that.”

“Have you always had this much sexual energy?”

“It’s always been in me, I think, but when I was younger it could never come out, never be satisfied. Men always wanted me, to their satisfaction. They never would satisfy me, and they would always judge me if I opened up about my real desires. Then I met Geoff.”

I looked at him, and he nodded. “Go on.”

“Well, he told me I could take other partners if I needed. That I shouldn’t be ashamed of my desires, that I should just be honest with him and fill them. That I COULD be honest and be with him and still release all my… my sexual energy.”

Her confidence in those words was very beautiful, very erotic, and I felt a faint stir of arousal and respect. I hadn’t known what to expect from the kind of couple one would meet for an encounter like this, but they were so… normal. Just trying to fulfill themselves sexually, like we all are. It just happened to be with me, a stranger-turned acquaintance-turned lover, on a nude beach (admittedly my suggestion, but they had been together before and like the idea). I turned to look at Geoff.

“It’s true mate. I just want her to be fulfilled, obviously with good guys and that, but I just can’t keep up with her, so sometimes I share her sexually.”

“You let me share myself.”

“WE share you…”

“yeah, yeah. Without you I would never have opened myself to it.”

They kissed, slowly and open-mouthed, his hand caressing her breast. I had learned something about them, it felt like becoming a part of something intimate. When we were all horny and turned on beforehand it wouldn’t have been possible to speak like this.

“So are you going to have one of us again?” he asked.

“Oh yes. Ian I think, and then you again when we get home.”

“That’s just fine. We WERE happy to find a young guy who can reload quickly. I might have a swim though. Don’t do anything TOO naughty to her Ian.”

“She’s just wonderful. I’ll treat her right.”

“I’m glad you see it that way. Remember though, she’s your woman, sexually, until she’s finished with you. Make her do a few things YOU want.”

“Well I have a few minute to think of something” I said, lifting my flaccid cock.

“Hopefully not too long” Tess said breathily.

Geoff just laughed, then took a deep drink from his water bottle and started towards the sea. My mind began to race. I had five or ten minutes until Tess would want to mount my hard manhood. I drank from my own water bottle, offering her a sip. She looked straight through me with those deep green eyes and I felt in her power, gravitating to the aura of pure sexual power she gives off.

“So, do you have any ideas?”

I did. Dirty ones. Fantasies I couldn’t have dreamed of filling before meeting them, even in my wildest adventures (which may become other stories).

“Yes. A few.”

“And?”

“You’ll see.”

I reached into my own small bag, taking out sassy-brand anal lube and a few durex magnums from it. “You won’t need those.”

My eyebrow raised. Geoff knew I was clean, and I knew they were, but still…

“I’m on the pill. Geoff agreed to meet you, you’re safe. We’re free to play naturally, however we like.”

“You don’t know what I’m planning.”

“I can guess. But we’ll see when the time comes. Surprise me, you’re new and you can still do that.”

“I want to take you off the beach. Even here we might be a little too wild. Let’s go up into the trees.”

“Oh, you think I might scream?”

“Yea, or I might.”

“Well then…” she hung on the ‘then’, making it a long seductive sound. Like the JOI video where the thick-bottomed hostess slowly says “hello there” before making you stroke in time with the slow wiggle of her voluptuous bottom.

“Shall we?” I stood up slowly, offering her a hand that she didn’t take, preferring to show her long legs as she squatted and slowly stood.

We walked off the warm sand and into the coolness of the shade, slipping between the trees, penetrating the forest until we found a small clearing 20 or 30 feet from the sand, large maple leaves and soft grass covering the ground.

Tess turned to me. “The safe word is cherries. I know you want to get bossy, and I might get physical. Tell me what you want.”
