Detention With Korean Schoolgirls Soo-Young and Sung-Hi were a teacher's worst nightmare. The beautiful and intelligent twin daughters of a Korean diplomat but very disruptive. This was surprising because most asian pupils I had taught at the expensive London school where I worked were very quiet, especially the girls. But Soo-Young and Sung-Hi were different. They seemed to take great pleasure in destroying my carefully planned lessons with wickedly timed interruptions or well aimed spitballs (that I could never quite catch them firing). Despite their age (they'd only just turned sixteen) they also had a cunning awareness of their bodies and how to embarrass a man. They would hitch up their skirts so high that the tops of their stockings were visible or they would remove their blazers in class to reveal a tight white blouse and no bra underneath. The evil bitches must've known I didn't dare look at them for fear of being accused of flirting with a pupil, but I also wonder if they knew how hard their teasing got me or how I used to dash to the staff toilets after the lessons to relieve my throbbing cock. As I have said, they were difficult to catch but one day they went to far and I put them both in an hour's detention in my room on Friday afternoon. Surprisingly they both turned up on time and got on with their lines in silence. Perhaps, I thought, I was finally getting control over them. I couldn't have been more wrong. It was at the end of the detention that they struck. I told them both to stand up and then I went to collect their lines, Soo-Young's first. I was expecting to see 'I must behave properly in class' written out a hundred times but what I saw on Soo-Young's paper left me speechless. Sir is a sissy-man slut. Then she smiled sweetly and drove her knee hard into my balls. I dropped to the floor and both of them were on me. Before I had time to recover each girl had produced a pair of handcuffs and locked my wrists to the radiator pipe that ran along the wall. 'He doesn't look so tough now, does he?' said Soo-Young to her sister. 'He sure doesn't,' replied Sung-Hi. Then she prodded me with the toe of her high-heeled shoe and added, 'Heh sissy-man, open your legs. It's my turn to give your cock a good kicking.' 'No p-please...' I stammered. I didn't think the damage to my manhood was permanent but it couldn't take another battering. I thought about trying to kick them but they could easily jump out of the way and I was afraid of making them angry. Calling for help was out of the question too. The caretaker might hear but I didn't want him to see me like this. Who knew what story the girls would make up? 'Hmm, I wonder if it's broken,' said Sung-Hi, kneeling down beside me and undoing my flies. Her hands were soft but strong and the feel of her long nails against my penis was stimulating, in spite of my bruised balls. 'No, it's definitely not broken,' she giggled as she stroked it erect. 'Quite a big one too. Pity it's attached to such a sissy.' 'Yeah,' said Soo-Young, reaching into her bag and taking out a pair of scissors. 'Perhaps we should cut it off and throw the other useless crap away.' I looked at her in horror, and only Sung-Hi's persistent tugging kept my cock from shrinking to nothing. 'Unfortunately I don't think that would work,' she said. 'But he doesn't deserve to wear a man's clothes if he's such a sissy. Cut those off instead.' 'Heh, that suit was expensive!' I wailed as Soo-Young went to work with her scissors, literally cutting my clothing off. 'Shut up bitch!' said Sung-Hi, taking her hand off my penis to slap my face. 'Or Mistress Sung-Hi will get rough, and you wouldn't like Mistress Sung-Hi when she gets rough.' She cupped my balls and began to squeeze. 'Beg me to stop,' she snarled. 'Please stop!' I cried. 'I beg you!' But Sung-Hi just squeezed harder. 'Say "I beg you to stop Mistress Sung-Hi" or I'll rip them off.' 'I beg you to stop Mistress Sung-Hi.' 'That's better. You must always address us as Mistress Sung-Hi and Mistress Soo-Young. Now, sissy-boy, do you want Mistress Sung-Hi to keep playing with you?' My cock was still rock hard and despite their cruelty I found the sight of these two imperious young women kneeling over me incredibly erotic. 'Yes please Mistress Sung-Hi.' She smiled and brushed the tip of my cock with a sharp nail. It twitched and seemed to grow even bigger, as if straining to reach the hand that was so tantalizingly close. By this time Soo-Young had finished removing my clothes and all that was left of them was a pile of rags. She stood up and kicked them out of the way. 'Hmmm, its going to be fun playing with our new dolly,' she said. 'Lets dress him up!' 'Yes,' said Sung-Hi, giving my cock a final, teasing stroke and then standing up. 'And seeing as he tells us to wear this stupid uniform, let's make him wear it for a change.' To my delight they both stripped off their clothes and I was soon privileged to a view of both girls hard, naked young bodies towering over me. Then the uniforms that still carried their warmth and scent were being put on me. I got Soo-Young's panties and stockings, and Sung-Hi's skirt, bra and tie. They didn't bother with the blouse. 'We want to see you in your pretty little bra, sissy-man. Doesn't he look great Soo-Young?' 'He sure does. In fact he looks so good, I think we ought to take some photos.' At this I panicked. If they had photos of me like this they could effectively blackmail me forever. 'Please Mistress Soo-Young, don't humiliate me like this!' 'Shut up whining you sissy,' said Sung-Hi. 'My sister can humiliate you any way she likes. Now stop talking and start doing something useful. My feet are getting dirty standing on this floor. Lick them clean!' With that she pushed her dainty little toes into my mouth and I sucked on them greedily. Meanwhile, her twin took photos of me. 'These would look great on the school noticeboard,' said Soo-Young. 'Which is exactly where they'll go if you don't do exactly as we say. Now, as soon as you've finished cleaning both our feet with your tongue we're going to play a new game with you.' Five minutes later I'd finished their feet and they were standing over me again. 'What game shall we play now Soo-Young?' asked Sung-Hi. 'How about the 'Triple Oh Fucking Game', that's always fun!' 'Good idea. How about you Sissy? Do you want to play the Triple Oh Fucking game with your Mistresses?' I looked at those gorgeous morsels of flesh that I'd secretly lusted after for so long. The thought of fucking them both blew my mind and I didn't need asking twice. Yes please Mistress Sung-Hi and Mistress Soo-Young!' I lecherously ogled their pert breasts and neatly trimmed pussies. How would I get to fuck them, I wondered. Would they keep me tied up and just straddle me, or would they trust me to be untied so I could fuck them from behind too. I hoped they would because I really liked their tight little ass and I'd love to feel them against my pelvis as I pumped into them. 'Good,' said Sung-Hi, rummaging in her bag. 'Let me explain the rules; Mistress Soo-Young sits on your face and you try and make her come by licking her. Meanwhile, I put this on...' she pulled out a big black strap-on cock, ' and fuck you up the ass with it. The feel of which, eventually, will make me come too. When we've both come three times its your turn. The Mistress who comes three times first will suck you off.' I stared in terror at the strap-on that jutted out from Sung-Hi's pelvis. The large dollops of lubricant she smeared it with did little to reassure me. 'Please Mistress, don't...' I started to beg but I was cut off mid sentence as Soo-Young straddled my head and jammed her sweet pussy into my face. 'Lick it bitch, and lick it good because it's going to take a lot to make me come before her.' As I sucked desperately on Soo-Young's clitoris I felt her sister grab my legs and push them up so my anus was accessible. Then I felt the cold kiss of lubricant as she entered me with her dildo. Only Soo-Young's pussy muffled my cries for mercy. 'Ummm, that's good,' purred Sung-Hi. 'I love the way the base of my cock rubs against my vagina when I pump it into you. But be a good sissy and try and push back a little, otherwise it can take me hours just to get off once, let alone three times.' In fact it did take hours, but in the end Sung-Hi came for the third and final time. My energetic licking had made Soo-Young reach Triple Oh first, so she brought me off in her mouth. She didn't want to swallow my come though so I had to open my mouth and she transferred it to me with a very wet kiss. 'That's all for today, sissy-man,' said Sung-Hi. 'But don't worry, you'll be having a lot more detentions with us from now on.'
