Standing in front of the mirror, I had just lifted my razor when I caught sight of Karen out of the corner of my eye. She wasn't dressed yet, and was only wearing her mint green cotton dorm shirt and bikini panties. I sighed inwardly. We were going to be late. She couldn't go dressed in her dorm shirt, no matter how pretty she looked. The worn nightshirt had a round neckline and little capped sleeves. The breathtakingly short hemline barely covered her bottom, and there was something undeniably sexy about the way the dainty but threadbare fabric clung to her curves.I just finished rinsing shaving cream off my face when Karen materialized behind me and yelled, 'Gotcha!' as she jabbed the ticklishly bare skin of my torso. I went over to the bed and and we wrestled, though I mostly tried to get in plenty of body contact. Karen didn't mind, but just giggled and fought back. At one point she was about to crawl away, so I grabbed the waistband on her white panties. I was really surprised when she didn't stop but just wiggled right out of them. I was left just holding the silky things when she turned and attacked me. I was really turned on by this, so I sort of let her have her way. In no time she was sitting pantyless on my chest. She pinned my arms to the bed and said, 'I gotcha now!' With Karen sitting on my chest, I let my eyes wander over her breasts, hovering beneath their veil of soft cotton, not far from my face, to the hem of her light mint green dorm shirt. I could see soft curls of black hair below her hem, and feel them tickling my chest. Karen smiled down at me for a minute, then leaned down and lightly kissed me, darting her tongue into my mouth. I clasped the cheeks of her rear and pulled her forward until my face was directly under her. Instinctively Karen lowered her pussy onto my outstretched tongue and then wiggled back and forth over my mouth, nose, and chin. 'Okay,' Karen said. She lifted her head. 'Okay? Now?' 'Now.' She sat up and let me do it my way. I pulled her over and tucked her under me. Her legs spread. I rose, on my knees, between them. She held my penis lightly, just guiding. I lowered my hips, touched, then slid on in. She was slick and mossy, tight yet not tight. The entrance was exquisite.I clamped on my teeth, thinking I was going to lose it right then. She sensed it, and held still. I pulled back from the edge, then was okay. I moved in her once, going in so deepI thought I touched bone, then slowly sliding back till I was almost out of her. She moaned. 'Oh, God,' she said. I realized I was holding my breath. I let it go with a whoosh, and laughed. Karen laughed too. Then we laughed together, into each others faces. We were celebrating the sheer joy of it, this wonderful thing we had together. I quit laughing and moved into Karen again. Her hips responded. And then we were together, meshing. Like we'd done it together a thousand times before. Yet, at the same time there was a touch of newness, discovering; the best of both. Incredible. Our hips were thrashing. I couldn't have described the things Karen was doing down there. Tricks with her inner muscles, I didn't know. We were making sounds, slapping, slurping. Her thighs were hugging, high on my back. Her hands made trails on my back and squeezed my buttocks. Her mouth sealed on mine, and she sucked on my tongue. It was as if she was trying to swallow me, take all of me inside her, not just my penis. Karen moaned in excitement with every thrust of my prick. To heighten her pleasure, I moved my hand down beneath the creeping hem of her light dorm shirt and rubbed her clit, moving in time with my faster and faster strokes. Then she shuddered, and I moved as fast as I could as she came. She writhed around on my prick and moaned as she was rocked by waves and waves of orgasm. I held her close while she recovered from her explosion. Then Karen gave me a dazzling smile and nestled between my legs. My prick was rigid with anticipation. Then I felt warm, soft lips, smooth as velvet, and her warm, wet tongue, as she enveloped my penis with her mouth. I felt Karen circle her lips below the head of my prick, at the ridge, and flick the tip of her tongue with feathery strokes across the tip of my prick, sucking lightly, teasingly. Then her lips started to slide down my shaft, exciting the tender skin, as her tongue continued its little dance over my tip. She slid her mouth that way all the way to the base of my shaft, and then slid back, making a slow, compelling rhythmn. I watched her whole body move as my cock, all saliva coated and slick, moved in and out of her mouth. I could even catch glimpses of her breasts beyond the fluttering neckline of her dorm shirt. Soon my nerves were singing. Minnows of delight darted up my spine, tingled my neck. And finally the momentous cataclysm began, the peaks of my feelings, stored up for this moment, and finally rising like some mighty geyser bursting from the bowels of the earth. I let out an unalloyed bellow and exploded.
