Part 2:
Lucas is surprised
'Crimson!' Carla gasped.
'Stop, Lukey, stop!' said Gerry urgently, letting go of Lucas's erection, which sprang up and away from Carla's face, flicking precum from its tip. 'That's our safe word. Are you OK, cunty?'
Lucas knelt back on his heels.
'I'm so sorry,' said Carla. 'It's amazing when you push my limits, but a living penis in my mouth...'
'I got carried away,' said Gerry, regretfully. She was still sitting astride Carla's stomach, and leaned forward to look with concern into her friend's face. 'I'm so sorry. Lukey, untie her.' Lucas shuffled back on his knees until he could undo the red rope binding Carla's wrists.
'It was a big kinky thrill up to then,' said Carla.
'Really? Honestly? Only now I think about it - I mean, making someone suck a strapon is one thing, but an actual cock... And it's not like our strapons are even very realistic.'
Carla smiled kindly. 'Right up till the end, I was more humiliated than I've ever been in my entire life. It was incredible. Let's just carry on, shall we?'
'To be honest, after what just happened I feel like I need to change direction for a bit,' Gerry said. 'Still, I promise I'll really bend your limits again before we finish, yeah?'
Carla grinned. 'Whatever pleases you, Ms M.'
Lucas cleared his throat and said, 'What's a strapon?'
But Gerry and Carla only laughed knowingly. Gerry said, 'OK, let's get back to the game. One, two, three, go.'
'Please, Ms M,' Carla said immediately, 'Cock-slave flicked precum on me.'
'He did! I can see a big drop on your forehead. Disgusting! Boy, did I give you permission to splurge cock-drool onto my precious slave?'
Lucas was beginning to get the hang of things. He replied in a pleading tone, 'Please Ms M, I'm sorry. I couldn't help it, Ms M.'
Gerry got up briskly and, standing astride Carla, frowned down into Lucas's upturned, apologetic face. A damp patch had appeared at the crotch of her swimsuit. 'I see,' she sneered. 'Apparently the boy can't help it.'
'You see, Ms M, when my cock's been hard and then it wilts a bit - I think it's with it being so dreadfully big, it holds such an awful lot of precum -'
'Silence! No excuses, slave! You have added to your crime of peeping and you will now pay the price.'
Lucas let himself soak up the full force of Gerry's scorn, and as he did so, a new and mysterious thrill flooded his genitals and spread to his whole body.
'You will start by cleaning up my cunt-slave. Bend over her face.'
Lucas shuffled into place on hands and knees.
'Not like that! Really get your head down! And stick out your tongue.' Gerry stepped to the side, bent, and peered at Lucas's face. 'Stick it out further! As far as it'll go. And stick your slave arse up in the air. That's better! Stay like that.'
Lucas was now resting on his knees and forearms on the smooth Victorian tiles, his tongue a few centimetres from the glistening bead that decorated Carla's brow. He held this undignified position while Gerry went to the tool chest. Rummaging noises followed.
'Cunt-slave, grab onto his upper arms and hold him there. We can't have the filthy wimp trying to escape his punishment.'
Carla's hands locked onto Lucas's upper arms.
When Gerry returned from the tool chest she asked, 'Remind me. Why are you my slave, you disgusting prick of a boy?'
Lucas dutifully kept his tongue sticking out. 'Becauthe I thpied on you, Mth M.'
'Speak clearly! For not speaking clearly, one stroke of my beautiful flogger.' Gerry moved to kneel beside him, and thrust something in front of his eyes. 'This,' she said, 'is my slave-flogger.' She was holding the flogger by its handle, its thirty or so black and red leather flogging-strips folded back into her palm. The handle was wholly encased in elaborately-woven black leather lacing - more of Carla's handiwork, Lucas guessed.
Gerry stood up and took a step out of his view. The strips of the flogger hissed through the air. There was a sharp slap like an audible sting. But the pain was nothing compared to the deep, thrilling sense of subordination that it brought.
'And what happened to your dick when you spied on us, slave?'
'It got hard, Ms M.'
'How dare you not keep your tongue out!' The flogger swung down smartly again. 'So! You will make amends for your crimes by cleaning that precum off my beautiful cunt-slave. Lick it up at once, and swallow it!'
Lucas felt great reluctance to lap up his precum. He looked down hesitantly at Carla's tanned, mature face, attractive even when upside-down, at her brown eyes and secretive smile, and at the liquid in the centre of her brow.
Next moment Gerry's hand gripped the back of his neck and forced his head down, crushing his tongue against Carla's forehead. He wiped his tongue across the salty precum and felt a delicious sense of abasement. Gerry was kneeling beside him, watching. 'Now kiss the damp patch!' He did so.
Gerry yanked his head up by the hair.
'And did you rub your dick while you spied on us?'
'Please, Ms M, I couldn't help it, you're so beautiful.'
'That does it! Hold your arse-cheeks open, slave.'
A few seconds later Lucas felt the strips of the flogger flat against his exposed anus. Then they were drawn upwards in the cleft between his buttocks. There was an unfamiliar sensation in his anus as the strips slid over it, a warm tingling.
Slap! Gerry was an expert flogger. The stroke fell precisely between his buttocks, the strips curling round so that he smarted from his anus to the back of his testicles.
His head was pulled up by the hair again. 'And did you cum while you were looking at us?'
Lucas had always lain down on his bed while he brought himself to a climax, but he knew what Gerry wanted to hear, so he said, 'I - I did, Ms M,' and waited, quivering inwardly.
'For that you will pay the ultimate price! Stay exactly like that, prick.'
After a moment, more rattles and thumps came from the tool chest. Lucas tingled to his core.
Now Gerry was standing next to him. Lucas felt something small, firm and damp on his rear, just above his left hand. It moved erratically to the right.
'What do you think I'm doing, prick?'
'Writing with a marker, Ms M.'
'Clever boy,' Gerry sneered. 'And do you know what I've just written?'
'No, Ms M.'
'I've written "Ms M's whore". Because you are going to be my whore as well as my slave. Do you want to know what that means?'
'No, Ms M.'
'You used us. Wanking when you spied on us, that was using us. So to balance things up, you are going to be used. And a whore's holes get used. See?'
