"Mak is cock mad", said Shin. "She wants to play with me, suck me, watch me cum, fuck me in different positions, indoors outdoors , whenever, whatever, almost whoever." The four of us were on the sofa. Mak was kneeling between Shin and me. SHe had both our cocks out and was greedily devouring our cocks moving from one to the other, sucking one whilst wanking the other. Conversations about porn over a meal had led to this. A story about three girls in a college in Kyoto who had together schemed to get good grades had seduced a professor. Dressed in their short uniform kilts, shortened as much as they could,wearing skimpy white blouses and their over-the-knee socks. They'd found him in the classroom. They had made resistance impossible. Masturbation through their panties until thy were cum soaked softened him up and hardened him up too. Then they concentrated on his mound before removing his trousers. Then worked on him in his pants until he was begging to be handled and sucked by his tormentors. They made him cum over his belly and then licked him clean. Poor lucky chap. Grade A's for half-an hour's work. Easy. Shin and I agreed that we should have been teachers in that sort of college. The girls had gone upstairs whilst we cleared up. When they came down they wre transformed into two of those college students. Black hair in bunches, tiny white tops exposing studded bellies, the shortest micro minis, which I knew Koko had for dressing-up sex parties. Panties flashed as we looked up. Hell, I thought at this vision of sex on legs. Any bloke's cock would have stiffened immediately as mine did. They stood before us and started stroking each other, hair, kissing, breasts under skirts and into panties. First they had fingers into their own cunts and then Koko knelt down and started sucking Mak. Had they done this at college together I wondered? "On to the sofa profs", they had said. After a good bit of teasing and stroking our mounds swelled noticeably me teasing with some mutual masturbation on their part followed by some glorious cock teasing. Unzipped, trousers down they teased more before eventually they released our expectant and hungry cocks. Pants pulled down They sprang free and the girls got to work. Mak went for mine grabbing it. "New cock for her", said Shin. "Nice and big" murmered Mak between mouthfuls. Koko was happy pleasuring Shin who was stroking her erect nipples with the tip of his cock. Mak was a professional. She knew exactly how to deal with my cock and my balls. She threw everything into it, sucking tongueing, ball massaging and nibbling, not the subtlety or finesse of Koko but mind blowing. Koko bent over Shin and slowly slipped her lips over the head. He let out a groan of ecstasy. I watched as her lips slipped down to his balls taking his whole length in. Then slipping it out, moist. She dribbled on to the tip and slid her lubricated hand down. He was frantically grabbing at her breasts then slipped his hands between her thighs which opened welcomingly. Into her pants he went and I could see it at work through the fabric. Then he slipped into her cunt. I guess it was moist from the sound. He gave her a finger fucking and clearly she came. He withdrew his hand an licked her juice off two fingers. When he returned she gasped with delight and expectation. Mak's head was still bobbing up and down purposefully in my lap. My hips were beginning to go and I would lose it if I wasn't careful. I re-arranged myself burying my face in her cunt sucking and chewing her before pulling her panties down and exploring her with my tongue. I felt her pants dampen from her juice. Meanwhile Koko it was evident from the noise and way Koko was throwing herself around that she had cum again. Both were now cock hungry and both girls were swapping cocks and sucking and wanking us crazily. I so wanted to shoot my cum over them. Why can't blokes cum time after time! I was overwhelmed but not surprised for over the meal Shin had told me that at college she had taken six other students as well as him. I could believe it. She seemed greedy and insatiable. "Lets go upstairs. The bed is big and comfortable and the mirrors make for fantastic sex. It's like watching a big group", I said, trying to get my cock back into my pants. Shin gave up so we started upstairs in various degrees of nakedness, Shin's erection very much on show juices flowing and spunk-filled balls aching. (Part 2 is dated 31st March)
