Caught by Step Brother

I hadn't had sex for some time, and whilst I am okay with masturbating I hadn't even managed to get around to doing that either. What with work, home life and the general pressures of things it somehow just never happened. I'm not at all comfortable with the idea of masturbating hurriedly or secretly - in the bathroom for example - I simply can't relax enough, so I don't try. For me, even when I'm really frustrated and need to find release, I always (nearly always) manage to wait until I have some private time to do it properly in my bedroom. So there I was, frustrated as hell and at last having managed to find some time alone in my bedroom. I had it all planned, I would take a slow lingering bath with a glass of bubbly and a few scented candles, and then dry off and go and play with myself and try to drag it out as long as possible. I like to tease myself as release, when it comes, is so much more intense. I run the bath, add some oils and light a few scented candles and grab a large glass of bubbly and put the radio on my favourite music channel. I resist the urge to touch myself anywhere which might start me off, like my boobs, nipples or clit and sit back and try and relax. I know what's coming later so my body starts to respond to the expectation and I feel myself becoming aroused. My nipples start to firm up, and my pussy starts to transmit those familiar sensations. Still I resist the urge to touch myself, resist the urge to let a finger touch my nipples or my pussy. I start thinking about a nice hard cock, the last one I had, how it felt in my hand, my mouth, my pussy. How the guys fingers had teased my nipples and played with my pussy and clit, the taste of his lips on mine and his searching tongue in my mouth. The sense of his expectation and his need to be in me. But still I resist the temptation to start playing with myself. I lay back, remembering previous sex encounters with other guys, and one with another woman. The temptation and need for release are beginning to become over-powering. I step out of the bath tub and start to dry myself taking care not to further excite myself. I know my pussy is aroused, swollen and wet, and my nipples are erect and hard. Even my breathing is a little heavy and my face and chest are flushed slightly. I head for my bedroom, I don't bother dressing or covering myself up as there is no-one else at home, and once there I throw myself on my bed. In my room I have a full length dressing mirror which is on wheels and when I am alone and have the time I like to place it so that I can see myself as I play. I've already put that into position, but check anyway making sure I can see myself and my parted legs in it. Now the tricky part. I reckon I have an hour before anyone gets home and I want to try and tease myself for 30 minutes of that hour keeping myself from cumming whilst getting as close as I dare. I start by playing with my boobs, avoiding my nipples which are super sensitive when I'm like this and can sometimes get me to orgasm simply by playing with them. Then after a while I let my hands caress over my chest and stomach, but when my hips twitch and I unconsciously lift them slightly I know I need to slow down After 15 minutes or so I'm really struggling to stop myself from getting carried away, my nipples ache and my pussy is throbbing and sending out those aching, empty, tingling, twitchy sensations. I'm okay rubbing and caressing my thighs and stomach for a while as that doesn't aggravate the situation, but doesn't help either. I open my legs wide and splay my knees to either side and look at my pussy in the mirror. God it looks so red and swollen and wet seeing myself like that is a sight which always turns me on even more. I so desperately feel the need for something in me, but know that once I do that I shall have real trouble stopping myself from going the whole way, and I want to last a little longer. But anyway I reach out for my vibrator and use it on my thighs and boobs. Then I let it slip across one nipple the sensations are electric. My hips jerk and my legs twitch as the sensations hit me. Eventually I can stand it no longer and let the vibe slip between my pussy lips holding it very briefly against my clit on the way. I am so wet it slips up me without my really trying, or was that my hips pushing up of their own accord to meet it? I feel it enter me and hear myself gasp as it does so and then hear myself making soft moaning sounds as I feel the sensations. I alternate my free hand between my nipples and my clit, tweaking and squeezing my nipples and rubbing my clit. I am so very close that I can only stand a second or so of either before I need to stop for a few seconds before starting again. I'm in a world of my own now, my orgasm very imminent and my whole being is centered on that one thing. I know I am making noises and know my hips and body are moving as my orgasm approaches a point where I simply wont be able to stop it. Then, just as my orgasm starts I hear a male voice gasp out Oh shit!. I can't stop my orgasm, my whole body is overtaken by it, my hips jerk, my stomach tenses, my head cranes forward, my thighs slam together and I groan out loud. But through it all I realize that my step brother is stood in the door way his trousers around his ankles and with a very flushed face and stroking his erect cock, which pretty evidently looks set to ejaculate all over the floor. I gather myself and shout for him to get out, and pull the vibe from up my pussy and try and cover myself. But even as I do this I feel a second orgasm building despite not touching my clit or nipples. But my step brother can't stop himself and at that moment his cock lets fly 2 or 3 loads of cum and his stroking becomes slower and more measured. I again try and shout to him to get out but seeing his cock cum sets me off and my now very unwanted second orgasm hits me and what I actually say is something like Get .Oh fucking hell. .. Out. Get out!. Afterwards, much later, and when its all settled down, we talk and despite my feeling very uncomfortable my step brother seems more at ease than me. Evidently he came home early, I was in the bathroom having my bath and with the radio on I didn't hear him go to his room. He caught a glimpse of me walking naked from the bathroom to my bedroom so thought he'd have a spy on me and was stunned to find my bedroom door open and me on the bed playing with myself. He thought I'd seen him much earlier than I had and that I hadn't minded him watching so felt comfortable dropping his trousers and wanking as he watched. Oh, and he asked if we could do it again!!
