Maz, gasping, did as she was told.
Justin dropped his boxers, his cock stiff and thick. I wanted it inside me, but I had to let Maz have her reward for services rendered. I would just have to watch and wait my turn, if I was to be allowed one.
‘OK, enough of that,’ he said. ‘Get on all fours and push that arse out for me.’
Maz rolled over and knelt up. The split in the latex crotch continued up the back of the knickers, exposing her bottom in a broad circle. It seemed wrong to call them knickers, somehow, since they didn’t do the job. What would be a good name for them? Sex pants, maybe.
Her pert white bottom gleamed between the boundaries of wet-look blackness, while her shaved pussy was well spread and juicy. Even I wanted to fuck it. If only I had a strap-on.
‘Now, I want you to ask me nicely,’ said Justin, kneeling and taking his cock in hand, preparing for the penetration.
‘Please, sir, may I be fucked?’ moaned Maz.
‘You may.’ The tip of his cock lined up with the tiny target, butting it gently. ‘How hard should I fuck you?’
‘As hard as you want, sir.’
‘That’s right. And where should I put my cock?’
I bit my lip, too tense to breathe.
‘Wherever you want to, sir.’
‘Good. I’m going to use your cunt tonight, since Keris is new to all this. Keep it nice and tight for me.’
‘Yes, sir.’
‘Now get your eyes off the floor and look at Keris while you’re getting fucked.’
She groaned, seemingly unwilling, but she lifted her head, turned it to the side and stared straight at me. It was most disconcerting. I hid my face in the wine glass, peering narrowly over the rim at her.
Justin’s cock slid inside, disappearing inch by inch, until his pelvis made contact with her bum. He took hold of her hips and began to thrust, slowly at first, so that I saw his pole glisten with her juices as it made its inexorable back and forth motion.
‘Oh, you are keeping it tight, good slut,’ he said, reaching down to squeeze a rubber breast. ‘Nipples good and hard, can you see them, Keris?’
‘Yeah,’ I coughed. Mine weren’t exactly flat.
‘I wish you could feel how tight and hot she is,’ he said to me. ‘She’s a fucking dream of a cunt.’
I put my glass down. It was no use. I was going to have to masturbate. My knickers were hanging off one ankle so it was easy enough to get a hand under my skirt and begin a frantic massage of my clit.
Maz looked so luscious, her face faraway and dreamy even though her eyes were still fixed in my direction. Justin was speeding up, his lean torso bent over her arched back, his cock beginning to pound.
‘Of course, I prefer a nice red arse, like yours, Keris,’ he said through gritted teeth. ‘But I can make an exception. Oh, are you frigging yourself? You bad girl.’
He turned his head and grinned at me. My fingers pushed down harder.
He removed one hand from Maz’s hips and dipped it down between her sex lips, swirling it round and round. Then he took the juiced tip of one finger and began to circle her arsehole with it.
My jaw dropped. I was going to come. This was too much.
The finger plunged inside Maz’s bum and she cried out, her eyes glazed, then shut. She was coming.
My own orgasm coincided with Justin’s, my watery whimper drowned by his roar of triumph.
‘Mmm,’ said Justin, his finger still plugging that hole. ‘Keris got a really good show. She watched you getting fucked with your arse filled too. How does that make you feel?’
‘Ashamed,’ said Maz quietly. ‘Humiliated.’
