As Tina left the secure area, she was glad to have finished another shift. She'd heard every joke in the book about the long climb to and from work in her high-rise crane cab, though she wasn't averse to cracking one of her own.

"Going down's always the highlight of my day, but I say that to all the boys," she told John, as he smiled at her through the mesh of the security fence.

John had stopped outside the construction site to make a call. It wasn't a particularly pleasant evening, and when an automated voice informed him there would be a thirty-minute wait to speak to anyone, he decided to leave a routine task for another day.

"All the lines were busy on the phone, so I thought I'd share someone's joy in finishing what they set out to do, instead," John confessed.

"You just wanted the best view of my sexy arse when I came down the ladder, really, didn't you?" Tina laughed.

"It's better than ogling from the window of my flat, and I needed some health-promoting exercise to get here, too," John replied.

Tina had been preparing to return to the portakabin that was her home while working on the site. It was a lifestyle she was used to, but one that sometimes left her craving the company of someone who wasn't a colleague.

"If you're single, have a working shower, and have a free evening, I'm sure we can share a few laughs. Someone who doesn't take themselves too seriously and doesn't live in a portakabin is exactly what I need right now," Tina explained.

Within twenty minutes of John confirming that he met all of her criteria, Tina was preparing to take a shower in the bathroom of his flat.

"You'll be able to become even better acquainted with my arse now," Tina giggled as she appeared naked in the bathroom doorway and gestured to John, confirming she'd enjoy his company in the shower.

Once John had removed his clothes, he stepped into the shower, while Tina enjoyed the sensation of the hot water on her body.

"Would you mind terribly if I fucked your cock with my arse? It's a bit of a liberty, I know, but I always stuff my fingers up my fanny in the shower after work, and an unexpected bonus might make everything just a little sweeter," Tina asked, giggling mischievously.

"Seems reasonable," John answered.

Tina began doing as she'd suggested as soon as John spoke. She laughed with delight as she pushed rhythmically against John's cock, and her expert touch rubbed her clit, and massaged firmly inside her body amid waves of erotic excitement.

The feeling of John's twitching cock drove Tina to escalate her own work inside her body and intensify her thrusts against him. The spontaneous nature of everything ensured she had no time to feel anything but pleasure, though she made sure John knew exactly what she wanted.

"We're going to work together until your cock raises the white flag of surrender," Tina laughed, ensuring John didn't need to worry about gentlemanly behaviour.

As she gripped the shower's handrails, Tina felt her body join John's in a pre-climactic state. It was a moment of sheer bliss. The shouts and squeals announcing their subsequent shared release rang out beneath the water, and two bodies went into spasm together in a triumph of opportunism.

Tina's deep plunges into her squirming body enhanced the pleasure of feeling John's cum firing between her cheeks. Wild surges of noisily celebrated climax delighted Tina as she continued to grind her buttocks against the willing hardness between them.

Though John was left bewildered by the intensity of Tina's movements, her sounds of pleasure were unmistakable. Her ability to coax an even more explosive release was fuelled by erotic need, and Tina wasn't going to leave that craving unsatisfied.

Tina focused determinedly, bringing a third orgasm from John's cock, and re-energising her own climax in the process. Her mind was in chaos, and so was her body, and she loved it all.

Though focused on enjoying the unexpected opportunity, Tina also reflected on what it had reminded her of. Seizing the moment and seeing where it led was something she'd vowed to do more often. In the midst of doing just that, she felt a sense of freedom she had long craved, though perhaps not in this form. It was a joy she wanted to share, but conversation wasn't at the top of her agenda, at least for now.

Once Tina had pumped out everything John had to give from his cock, they stood under the shower's spray with broad smiles on their faces. Tina's body was still electric with the repeated pulses of her climax, and turning around to let John replace her touch with his ensured she got to enjoy them all.

The bonus element of the fun made something that had already been good even better. It also allowed Tina to experience more pleasure than she could recall having had in a long time. This was certainly true for John, as well, although it was left to Tina to speak about her feelings on the matter.

"We must do this again very soon. It would be a terrible shame not to," Tina whispered.

"I agree. I guess this is the moment to confess that I'd never done that before," John said with a laugh.

"I suppose this is when I whisper, 'me neither,' but I hope to do so again very soon," Tina replied.

After their initial fun, Tina's wishes were repeatedly and enthusiastically granted, along with many other requests. John, meanwhile, watched Tina climb to and from her lofty cab each weekday, though he usually saw her more clearly after she'd descended and walked the short distance home to his flat.
