An Introduction to Depravity 3 pt 1

An Introduction to Depravity 3 pt 1 ( LittleLillyfamilyfun / Lilly_Caress ) It was a few of weeks after my Birthday, and the shock of watching my boyfriend fuck his sister had died down. My sister and I had been close for years, so it didn't freak me out as much as it would most people. I, of course, has assumed that it had been a one-off, a special surprise, taken a little too far, for my birthday. Steve knew of my bisexuality, and knew that I found his sister very attractive. Our relationship seemed stable and we barely mentioned Tanya over the weeks that had followed. Steve called me this particular wednesday, his family was going away that from Thursday through to Monday. They'd gotten a last minute deal on a trip to Europe. Eagerly I accepted his invite to spend the weekend, it had been lonely in college, and I'd been missing him. He arranged to pick me up on the Friday evening after my classes had finished. Happily, I packed my rucksack that very evening, selecting my sexiest lingerie and and dresses, a skimpy negligee I'd just bought, and some heels I'd picked up in a charity shop! Friday finally arrived, the days before passing as if in slow motion. My lectures and lessons of the day seemed to drag on and on. At last, the day drew to a close, and I rushed to my dorm to grab my rucksack and headed out into the gloom of the early evening and the soft patter of rain. His car pulled up, just as I was beginning to feel miserable, the rain had plastering my long red hair to my head and leaving it hanging in limp tendrils down my back. I hopped in beside him, shivering, throwing my rucksack onto the back seat and gratefully accepting a warm hug and long sensuous kiss. We sat in comfortable silence after an initial burst of chatting and catching up, the warmth of the car relaxing me and quelling the chattering of my teeth. The drive was only a couple of hours, and before long, I was fast asleep. I woke about fifteen minutes away, chiding Steve gently about letting me sleep for most of the trip, but actually glad that he had. He seemed happy and relaxed, in a good mood. We chatted lightly about people we knew, and how they'd closed our local pub for a refit, until we arrived. I was ready to get out of my damp clothes and snuggle with him while we watched a movie. I was looking forward to a little fooling around, some intimacy, and the satisfying orgasms that a really good fuck would bring me. By the time we coasted to a halt I was desperate for a pee and a shower, no sooner had he unlocked the door than I ran to the bathroom to relieve myself, then stripped down for the shower, leaving my coat and clothes in a messy pile on the floor. After drying myself and my hair, I wrapped myself in a huge fluffy towel and headed downstairs to find my boyfriend and my rucksack. I winked at Steve and asked him to trun around while I dressed, he grinned as he grabbed a blanket and settled on the sofa. He turned on the TV and began flicking through the guide for a movie for us to watch. As he did that, I slipped into a pretty little black silk and lace nightie I'd bought especially for this weekend, it settled just below my bum, and just had a sheer lacey panel over my breasts, proudly framing my small rosey nipples. I glanced at the clock, it was 8.30pm, the night was young and I was completely at ease. Steve had already poured wine and informed me that food was on its way. I watched his grin widen as he saw me in my nightie and I posed in a mock sexy fashion for him, then slipped into the warmth of his arms and the fleecy blanket. The film was some kind of soft-core, art-house erotica, centering around a young French couple. Beneath the blanket I had undone Steve's jeans and slid his sizeable cock out, caressing and stroking it as his fingertips danced over my soft, silky-smooth mound and teased my sex. As the young couple on-screen made love in a derelict barge, I was moaning softly as his fingers slid inside me, causing my hips to writhe and my breath to quicken. In my hand the hardness of his shaft pulsed and throbbed delightfully. My hips were bucking into each thrust his fingers made, every fibre of my being, each sense attuned to the building sensation of bliss. . my moans were soft, mewling sighs of pleasure... I didn't hear the front door open. Unable to contain it any longer, Steves fingers working magic over my g-spot, I came hard, spurting and moaning as my orgasm hit me, the blanket slipping down my chest, my nipples proudly stiff beneath the lace panel of my nightie, panic in my heart as I cried out.. "Ohhhhhhh fuuuuuuuuuuccccck" As in walked Tanya, his sister, laden with with cartons of Chinese food, and a huge grin on her face... "I see you started without me...". She said, then walk past us into the kitchen. I snatched my hand back from Steve's cock, panting, trying to get my breathing under control, my boyfriends fingers still inside my spasming, clenching, gushing pussy. Although undeniably aroused from being caught, I was completely confused as to why Tanya was here, and absolutely furious with Steve for now warning me his sister would be back and not on holiday with his parents. I punched his arm, demanding answers with hissed whispers as I pulled the blanket round me and covered up my arousal. I could hear Tanya gathering plates and setting up the table in the kitchen. Steve assured me he'd explain everything. He hitched up his belt and headed into the kitchen. Wrapping myself in the blanket, doubts and horrible suspicions whirled through my mind. I'd enjoyed my "birthday surprise" almost as much as Steve seemed to have. I had understood my birthday night to be a one-off night of illicit taboo sex and depravity. But now this? Had I been lied too? Had they carried on their perverse passions behind my back? Steve knew just how attracted to Tanya I was, perhaps this was something similar? I took a decidedly unhealthily large gulp of red wine, let the blanket fall and strode into the kitchen with fire in my belly. I sat opposite the siblings, my legs bare, my bum chilled by the leather, acutely aware of the wetness on my inner thighs. We ate and drank wine in silence. A palpable tension obviously emanating from me. Still the thoughts of that night replayed in my head, along with imagined trysts and secret sweaty couplings of brother and sister twisted my stomach into knots. Tanya excused herself and headed up to her bedroom as soon as the table was cleared, I stalked back into the lounge to see the young French couple on the screen kissing, frozen as the credits rolled over their faces. Steve strolled back into the living room, a strange expression on his face. I downed another half glass of wine, feeling it warm and lessen my disdain. "Start talking Steve...". He stood in silence, his face a battleground of emotion, a single tear bled from his eye as he struggled to articulate what he was thinking, trying to put his feelings into words. My heart melted at seeing him so vulnerable, but my heart sank with dread at what he might say. "Lilly... ", He groaned, "I love you, but I love her too, beyond words, she's part of me, part of my life, and since that night, I can't stop myself...", he was sobbing now, tears streaming down his face. "... I.. I... don't know what to do..". introduction,depravity,introduction depravity
