[First Time] Brother and sister complete their education with us!

[honister]

I went to Uni leaving my 'on off' girlfriend back home. During my first year I had a couple of memorable one-night stands with other students but we notionally stayed as an item. I sailed through my first year exams with top grades. In the summer holidays – now free and wanting to make a break from her hometown Mary said she wanted to come over and live with me. I agreed and we got an option on this little flat together above the landlord’s son’s bed-sit adjoining the landlords’ house.
During the summer holiday before we went back to the University town we had a holiday as a young couple on a popular Scottish Island in a chalet with lots of other families and older children around. We got particularly close with a brother and sister from Bristol there with their parents. It was clear we were all attracted. One memorable night at the end of the week after quite a few drinks I was on the sofa with Susan the younger sister of David who was the first to raise the stakes when he put his hand very slowly up Mary’s skirt as they lay together on the bed. We were all supposedly watching a TV film. I was so aroused watching his fingers get ever closer to her panties. I started fondling Susan’s pert young breasts and slid a hand up her top. It was so erotic feeling her nipples harden at my touch. She sighed then she smiled and snuggled into me. Her thigh was against my now hard cock. Noticing this she started rubbing my cock through my trousers. When I moaned she got it out and started wanking me as I watched over the back of the sofa seeing David slide his fingers inside a squirming Mary - her black panties being eased aside. I knew this is what had happened mostly by knowing the sound she makes when first entered –a sort of guttural exhalation and the words’ Oh God yes’. The colour of the panties i knew as i had seen her get dressed after a shower not a couple of hours before! The lights were off so the views weren’t brilliant by the light of the flickering TV. David kept sort of looking over maybe to check I was ok with developments but maybe a bit fascinated by his sister whose bra and top were now pushed up revealing quite puffy still growing harder nipples as I sucked on them. Protected by the sofa back from any lower view by them we had the better view, which is maybe why I dared start unbuttoning Susan’s jeans and unzipping the zip. As I forced my hand in and down the pale green panties the smell of her arousal hit my nostrils and the moist heat warmed, then as I cupped her mound, wet my palm. I withdrew my hand then slipped her trainers off and pulled the jeans from the bottomThey were super tight and so dragged the wet panties with them revealing Susan’s quite hairy pussy. I stopped when i got her jeans to knee level. Without removing her jeans I pushed her legs up and forcefully slid my head between her upper thighs trapping my face against her pussy. She gasped at the adventurous intimacy as my breath cooled her wetness. She had pale pubes but the pussy lips were swollen and her little clit was clear and obvious. I homed in on my target as I went down on her. She went wild - turned out no one had ever done it to her – indeed we talked on a walk the next day and she said I was the first guy to make her come – then she added only one other was allowed to try and I realised how inexperienced she was despite how she acted. As I licked on her throbbing clit,I could feel her thighs tensing as I forced one then 2 fingers deep inside her incredibly tight pussy my ears could also pick up Mary’s sucking technique and David’s moans. A couple of minutes later Susan tensed rigid, said ‘Oh fuck yes’ and her pussy clamped down hard on my exploring fingers then she went limp… I struggled my head out to see Mary looking at me somewhat angrily. I suspect she hadn’t imagined things going this far….That said David was laid out on the bed jeans at his knees and she was wanking his cock whilst sat astride him facing his feet and the sofa. Her bra was pushed up but her top was off; one of David’s hands fondled her left breast and the other was coming around her right thigh towards her pussy as he lifted the skirt. Rather unsportingly I thought Susan has by far the sexier tits darling and smiled. That said I nearly came on the spot. Even if you don't really fancy your girlfriend that much any more it is quite a thrill watching her have sex as a spectator!!! Mary was obviously aroused but also clearly jealous and doing stuff to get even it seemed. As I watched she adjusted her position to get David’s cock at her pussy entrance. Her eyes never left mine as she pulled her panties aside and sank onto his cock. She bit her lip as he went right up inside her. He moaned. I wanted equality now so I pulled Susan’s jeans and panties fully off and said to her ‘Get on your knees you sexy thing’. Her tits jiggled as she rolled over and she smiled as her pert little boyish bum was raised before me –and Mary was going slowly up and down on David to my right. As my cock got free and moved to just behind her pussy I could feel the heat of Susan. She whispered ‘ I’m not on the pill’ I said ‘it’s ok I won’t come in you’ then without waiting to check if that was ok I slid balls deep in her. Later I learned that I was only the second man to do this and the first boy had come after 3 short strokes. I may have been the first cock to touch her cervix as I bottomed out in her amazing tight wetness. Now this was erotically surreal. I was slowly fucking an inexperienced Susan as Mary completed David’s education and we couldn’t keep our eyes off one another. I did part Susan’ buttocks at a particularly bright bit of telly and notice her perfect little sphincter wink at me after which I forced a wet pinkie in there which made Susan moan and squirm still more. Mary started to compete verbally now saying ‘God your cock is the biggest I have had’ and doing a succession of quick deep strokes up then down. David said ‘ Oh Christ’ and from his sounds clearly started to come in her, which made Mary come as she was furiously rubbing her clit as she rode him. All this was too much for me and despite promising to pull out I pushed right into Susan and emptied my balls deep inside her with a wailing cry. I collapsed on top of her pinning her to the sofa as my brain literally blew a fuse…..
Seconds later Susan squirmed out from beneath me and hissed ‘you lying bastard you promised..’ she went to the shower and I found her washing her pussy with the end unscrewed washing my sperm out. This was the first good look at her nakedness i had got, She looked even sexier still when angry. I nibbled her ear and she laughed and forgave me when i said i couldn't pull out in time you are just too sexy - way sexier than Mary " Really" she said... David was still flat out on the bed when I returned. Mary was kissing him. She had the luxury of being on the pill !

Susan forgave me enough to have secretive sex outside the night after behind a chalet but after the mishap of the night before I got to explore the opening I had only fingered the night before! Fun though being the first up there was, it had none of the erotic forbidden charm of the ‘memorable for life’ night before! However she did give me a present that I asked her to bring for me, a treasure I still have to this day - her pale green panties from the night before! Crusty and lacking in smell though they are today they are a visual trigger of a never to be forgotten erotic episode in my sexual life

move to fiction?

[bluebaron]

Is it fiction though?

It's a nice, plausible story, until informed otherwise I think it stays right here.

This happened as described - I can assure you that it is seared into my memory from 33 years ago

I am sure this is a great story - but have you not heard of paragraphs? This is really difficult to read without paragraphs! Just a tip for future postings!
