"So, you put your fingers on the sides, feeling the slight bulge and then slip the end into the little slot."
Dave nodded as Robert showed him the plastic spool that the film needed to be loaded onto for processing.
"Then, when the end is in, you slide your fingers up and down and one part of the spool moves and pulls the film on."
Robert had demonstrated with some developed negatives, but now they needed to repeat the process with the newly exposed films and in the dark.
The next lesson was using a film puller and the older man showed how the the metal tongue was slipped into the tight slot of the 35mm film canister before the film was rewound until it clicked into place and then the tongue removed, pulling the flap of the film out.
Dave was trying to concentrate, but his mind wandered to the bedroom where Anna was napping, his semen inside her, her juices on his, no longer virginal, penis.
Robert trimmed the ends of the films and started to slide them onto the spools, then put everything into a big, black bag and zipped it up to keep out any light. His hands went into the elasticated holes and his face took on a look of extreme concentration as his hands moved. After several minutes there was the sound of loud clicking as the processing tank was put together and then Robert pulled it out, now loaded with three rolls of film, ready to be processed.
They had lost track of what films were what in the excitement. Some were taken by Robert of the staged scene in the kitchen as Anna, the bored housewife and Dave, the randy plumber, had had some fun. Others were by Dave of Anna blowing her boyfriend and the rest were of Dave licking Anna or the moment when they had sex on the bed. Dave was keen to see them all and was slightly disappointed by the rolls that still sat on the table, waiting to be prepared.
The two men had decided that clothes would be a good idea, in case chemicals were spilled and they worked as a team measuring the chemicals and diluting them and setting out the hanging clips and the rest of the chemicals.
Next it was Dave's turn to load two films into another tank, that way, Robert had explained, they could quickly process those as the first ones were being finished off. They had a small production line set up and Robert set the timer as they waited to start.
Both men were absorbed in the work, three rolls of film were hanging up to dry and two were almost ready. They hadn't had enough time to look at the negatives, but could see there were images and the distinct outline of a hard cock was on some.
"So nice" Anna said as she watched them in the kitchen. She was leaning on the doorframe wearing only a pair of lacy black underwear shorts. Her breasts had the trails of dried sperm that had begun to crust.
It took a few seconds for them to realise she had spoken and then they both turned quickly, Dave's cock rising in his jeans as he saw her.
Anna stood and watched as Dave pulled the developed film out of the tank, holding it up and wiping his fingers down to clean the excess water off it. She moved closer to peer at the images, her body pressing to his as she looked at the photos, seeing herself in some, her lips around a cock, her eyes looking right at the camera, all in reversed monochrome.
Dave hung the films up with the other three, five rolls hanging to dry, swaying slightly as the weighted clips caught the breeze. The three of them scanned the negatives, Dave and Robert recognising some shots and, therefore, the scene they were from. Anna stared at one closely, seeing herself in a wide shot, her breasts were exposed and Dave's hand clearly up her skirt. Her body twitched inside with the memories of earlier and she wanted to do more.
Robert looked at the kitchen as Anna leaned against him. "The light is wrong now" he sighed. "We could do more another day, but it needs to be earlier than now." Anna sighed too.
"What else could we do?" she whispered, her eyes flicking check where Dave was.
The couple's eyes flared as they had the same thought.
Dave was pottering about, helping to clear up the equipment as Robert took the chemicals away to the storage cupboard. He was still slightly nervous in the couple's flat, but hid it by gently humming to himself as he put the wet processing tanks on the balcony to get the late afternoon sun to dry. He made sure the kitchen was tidy then looked around for a final check, realising Robert had gone, as had Anna.
He crept down the hall, the bedroom door was open and he glanced in, spotting Anna's foot on the bed and then noticing another foot, this one pointing in the other direction. His humming had obscured the soft moans from the room and when he stopped he could hear the couple clearly, her gasps and his grunts, mixed with the faint creak of the bed and a wet, stirring, noise that took a few seconds to register. He tried to remain silent, but he must have made some noise as Anna soon called.
"You can come in, David."
He walked in and looked around the door, trying to be casual, "Oh, hey. There you are." He mumbled as Robert ground his hips against his girlfriend on the bed.
"Sorry, David. I needed Robert and he needed me." She managed to say clearly, despite being fucked by her lover as she spoke. "You can stay and watch. We got too carried away to ask you when we started."
Dave smiled at her and nodded, agreeing that it was fine that they had started as he tidied up. He felt slightly awkward, but Robert looked at him and smiled as his hips continued to grind against Anna's. Relaxing slightly, he knelt on the floor next to the bed and started to watch, entranced by Anna's breasts as they moved with each push of the penis inside her, the nipples hard and red, brushing against Robert's chest now and then as the couple moved together.
Robert moved, pushing himself up and then kneeling, his cock still inside his lover as he continued to move inside her body. Dave also moved to kneel up and get a better view, looking down at Anna's open vulva, spread wide by the cock inside it, captivated by how it could take a whole penis and not even show any signs it was deep in her. His eyes opened wide as the cock slid out. Robert was a bit bigger than him and seeing him, wet and very hard, sliding out of her body was incredible. The head popped free and the cock sprang up, soaked with her juice and twitching slightly.
Anna smiled up at her boyfriend as he hooked his arms under her knees and lifted her legs back. Dave watched as her pussy came into better view, wanting to lick those slick lips again and slide his tongue into her once more, to taste her slightly sour juice and lap it from her tight cunt. He was so lost in those thoughts that he didn't really notice that Robert's cock had moved away from the delicious hole he was dreaming of. Dave was brought back by Anna's gasp and his eyes moved, just as Robert's soaked penis had, to behind the open pussy. David shifted to get a better view and Anna reached up to pull her legs back and wide to help her lover and the watcher have better access.
Robert pushed and Anna's sphincter resisted for a second or so, before it was forced wide and the cock slid into her rectum. All three gasped as half of Robert's cock vanished into Anna's anus on the first push. The couple were still for a few moments, just the sound of their hard breathing disturbing the scene, then Robert pushed again and Anna groaned as her lover went fully in her, spreading her rectum wide as he pushed inside. Both of them looked at Dave, but his eyes were fixed on the point where Robert's groin was pressed against Anna's behind, his cock fully buried in her anus, her pussy lips wide and wet.
Anna groaned as Robert moved, sliding his cock back, the ridged head stroking down her anal passage before she was spread wide as he moved back up. She stroked down her body, palms rubbing her hard nipples and one hand sliding over her belly to reach for her protruding clitoris, the tip free of the hood as the cock slide up and down in her anus. She looked over to Dave, he was still watching as the cock emerged and then slid back inside her.
"David" she whispered, "do you remember what I told you about cumming when I have anal?"
Dave nodded, slowly moving his eyes from her pussy to her face as she smiled at him.
"Do you remember, David?"
He nodded again and watched her hand, still just above her labia, wondering why she wasn't pressing onto her clitoris.
Anna moved her hand and Dave watched it as it reached for his. She looked at him again.
"You are the only not naked, David."
