A few weeks later.
Tim was looking forward to this evening. He'd rung Bob and they both agreed a session in the darkroom was long overdue, and he could feel himself getting slightly hard at the prospect. In addition Neeta had been pestering him about some photos of the children which she said were in the camera but which he couldn't remember taking, and Bob had just got to the end of a roll of film as well.
There was something about Neeta which he couldn't quite put his finger on. She seemed to have changed in the last few weeks becoming a little secretive and he caught her looking at him a little oddly on a couple of occasions. He could also swear that one night he had woken up to the bed shaking very slightly as if she was cumming but when he looked she was laying still and breathing deeply, seemingly asleep.
He did feel a little guilty about the way he had ignored her recently in bed but every time he thought about Bob and what they did together he'd have to take himself off to the toilet and masturbate which didn't leave much energy or inclination for his husbandly duties.
Then there was Angie who'd come to stay with them for a few days. He'd never got on with her much when they lived where they did before but he hadn't protested when Neeta said she was an old friend and wanted to invite her over for a visit. Her attitude towards him however, had seemed even more sarcastic and supercilious than he remembered and he was glad when she had departed after 4 days.
Bob was in much the same position with Mary. He'd noticed a change in her attitude towards him, more independent almost offhand at times, but he was enjoying his liaison with Tim too much to worry about it. He too had to take himself in hand quite often as he thought about and explored his bi-sexuality. Like Tim he too had sensed that Mary was masturbating beside him one night and had kept very still until he felt her very controlled soft jerking and heard her soft gasps as she climaxed. It had turned him on tremendously and he had thought about turning to her with his erection but she had turned away from him and within a matter of seconds was snoring softly.
Although Tim had been into the darkroom a few times by himself and wanked off looking at the pictures they'd accumulated, it wasn't the same as when Bob was there and he too was looking forward eagerly to this evening. He felt his penis start to thicken but he resisted the temptation to do anything about it saving it for the evening.
'If you're going to spend all evening in that shed with Tim,' Mary had said. 'I'll get Neeta and the kids over here. They can have a sleepover while Neeta and I have a couple of glasses of wine. I'm not going to sit here by myself bored by the tele!'
Bob went round about 7 and Neeta and the children hurried off to their neighbour. They made sure the coast was clear and waited a few minutes before they made their way to the shed. Once inside they turned on the external red light to warn anyone against entry, and locked the door.
They immediately went into a clinch and Bob felt Tim's tongue enter his mouth. They remained like this for a few seconds pushing their crotches together until Bob felt Tim pull back slightly then a hand cupping his semi-hard prick through his trousers. He did the same and was pleased to feel Tim's hard penis pushing against his trousers, and they stood there rubbing each other through their clothing, kissing as they did so.
The next thing Bob felt was Tim fumbling with his belt then opening his fly and releasing his waistband. As his trousers dropped to the floor he again felt Tim's hand caressing him this time with only his pants between them. He moaned with expectation as Tim slowly pulled these down then gently gripped his rigid shaft. He felt fingers moving softly up and down his prick then cupping his balls below before Tim broke away and went down on his knees.
He lent back against the bench and watched as Tim pulled back his foreskin to expose his wet purple helmet and twitched a little as his tongue snaked out and started licking all round his glans. He then saw Tim's mouth open wide and slowly engulf first his glans then most of the rest of his shaft as well until he could feel it pressing against the back of his throat. He was always amazed at how easily Tim could deep throat, something he'd never been able to do himself without gagging.
He pushed his crotch forward as Tim started slowly moving his head back and forth, relishing the tonguing the particularly sensitive underside of his helmet was getting. Although he was really enjoying it he knew he wouldn't be able to withstand the feeling for long before squirting so he reluctantly pulled Tim away and bent down to french kiss him again.
'My turn now,' he breathed pulling Tim up and dropping his trousers. When he looked down he was surprised to see Tim had left his pants off and his penis was sticking straight out from his body. Like Bob he too had a foreskin which was part retracted and Bob just eased it back until the whole of his wet penis head was on full view.
Dropping to his knees he immediately took as much of the prick into his mouth as he could and repaid the action that had been meted out to him. He lapped his tongue up and down the shaft and round the head and tried to force it a little way into his pisshole. He could feel Tim's reactions and knew if he carried on much longer he would soon feel and taste his discharge so he reluctantly pulled back and just looked at the now wet penis twitching in front of his face.
'Perhaps we'd better slow down a little,' he said, 'and do the films. We don't want to finish the evening too quickly do we.'
Tim nodded and for the next few minutes they busied themselves with chemicals and tanks and rolls of film until they had both rolls of negatives hanging up to dry. They had both removed their lower clothes and had fondled and kissed each other while working but their main attention had been on what they were doing. As a result both their penises had gone soft but both were still wet from their own secretions.
It was Tim who spotted it first.
'That's funny,' he said softly, 'I don't remember taking these.'
He was examining his roll intently now, looking at 2 or 3 of the images in particular. It was not easy to determine the true picture by looking at the negative but he had 2 images of a semi naked woman that he definitely hadn't taken and another with the woman holding some sort of card with a hand-written message on it.
'What the fuck's all this?' he said.
Bob was also looking intently at his film and could see similar images on his.
'We'd better have a look at these' he said and set about printing a contact sheet. This produced small pictures of all the negatives but enough to show what they needed to see.
'Fucking Hell.' Bob swore softly to himself as the pictures emerged in the fixing tray. The ones he was most interested in showed Neeta naked from the waist upwards and looking straight at the camera. Although small they showed her dark nipples quite clearly and in one where she had her arm raised, the hair under her arm.
'How the fuck did these get here?! Tim I swear I know nothing about these!'
But Tim was too busy examining Mary's large breasts on his film to be angry at his friend.
'Look what I've got on mine!' he said turning to Bob.
Together they examined the pictures and almost together came to the conclusion that their wives had been up to something. The hand-written card Neeta was holding was too small to read so they put it into the enlarger and focused it on the base. Although still negative they could quite clearly read the words.
Look in the back of the drawer under your bench. Read what is in the envelope and follow the instructions carefully. We know what you've been up to all these months.
