I was 18 and in the 6th form - it was an era of Mayfair and Penthouse and a vivid imagination before the internet made it all explicit...leaving less to the imagination. My girlfriend Mandy was a year older, having left school previous summer, and was staying with a middle-aged couple, whilst she went to college, to do a medical secretarial course. We had arranged for me to visit on a Saturday and stay overnight, expecting I would be shown the spare room as Mandy's room was alone in an annex. Mandy was demanding sexually, always wanting to explore, would want me to finger her in the most dangerous places, and notably sometimes becoming so wet we needed a towel and I remember having to explain to my Mother, I had spilt a glass of water on my bed at home... I arrived, and dropping my bag in their hall, said hello to my hosts - thanking them for hosting me for a night. Bob was an affable guy quickly explaining he was on an overnight fishing trip. Eve was an attractive and friendly woman in her late 30s lady, not looking like she had 2 children, who would be around looking after their 2 children. We went out for the evening. On returning home, to my surprise, my overnight bag had been moved into Mandy's bedroom by her the landlady. Mandy was demanding and pulling discreetly on my hand, was desperate to go right to bed to have sex. Offers of tea, toast and anything were declined and there was no doubt Eve knew exactly why but was too diplomatic to have mentioned it. Eve had appeared in a dressing gown explaining she expected that we might want to sleep together, it was 'natural' (not sure Mandy's Mother would have agreed!) and as we had not seen each other for some time she assumed we would want to go right to bed. Mandy and I attempted to look casual about spending our first full night together. Eve's children were sleeping soundly in the main house, so no worries there. Mandy suggested she go to the bathroom first and she rummaged around in a top drawer before departing with her wash bag. I waited expectantly, and as an 18yr old expecting something like Mayfair to appear, becoming increasingly aroused in anticipation of the first time we would sleep together for an entire night! Mandy returned in a dressing gown, with clearly nothing underneath as her nipples protruded. She insisted I go to the bathroom, denying me instant pleasure. I went to the bathroom and excitedly finished with a large swig of mouthwash, and on finishing, wrapped a town around my waist unable to conceal a prominent erection in anticipating of repeatedly fucking Mandy all night. Penthouse had nothing on this! I opened the door of her bedroom to find it much darker than when I left it, only lit by the bedside lamps on either side throwing only a glow of light over the bed. Mandy lay in the centre, one knee raised, sitting up seductively on her elbows, wearing shocking pink lined black Anne Summers nylon split crutch knickers and bra with erect nipples protruding. I noticed she had slightly too much lipstick, and had also used in on her nipples too, which were fully engorged and protruding and fulfilling a fantasy she had forced me to exchange. I leaned forward to kiss her, and she tugged at the towel which fell away leaving a large erection. She leaned forward, confidently reaching for my cock, virtually shaking hands with it and pulled back my foreskin to reveal the throbbing purple head of my cock as she squealed in delight cupping my balls in her other hand - 'just fuck me now'. Her legs parted wider then needed but indicating how much she wanted me to penetrate her. Using her hand, and 2 fingers either side to part her vulva, she used the other to pull my cock towards her very wet vagina. As I kneeled between her open thighs savouring the moment, she placed her hands on my buttocks and literally pulled me into her without foreplay. Coming virtually right away she shuddered silently as she did so. It took only a few strokes and I felt myself spurting seamen into her...mingling with her now incredibly wet vagina as I filled her in a succession of spurts as I emptied my balls. We kissed erotically, not warmly as we might have expected, indicating she wanted much more, inviting me me to rub her gently as she held my cock expecting the situation to do the foreplay for her...she was lazy like that - keen to offer her vagina, but not prepared to work for sperm. We must have been lying there for about an hour. There was a gentle tap at the annex door and Eve's voice 'hoping she was not intruding'! Mandy smiled as she reached for her dressing gown' saying she has seen Bob and Eve in various states of undress since living there. Dressing gown girlie chat from Eve was not unusual, although she had not expected it now. Mandy answered the door to find Eve with 3 cups on a tray and ushered her in as I quickly wrapped a towel around my waist - albeit now thankfully without the erection! Mandy gestured for Eve to put the tray on the corner of the bed, and ignoring the vacant armchair Eve chose to sit at the bottom of the bed constantly re-arranging her dressing gown. She was intrigued to know if we had sex already? As I stared anywhere else than Eve, Mandy smiled and confirmed. Eve's dressing gown gaped more than I would have expected, noticing Mandy's was doing that too, revealing the cheap erotic lingerie from Anne Summers. I was really hoping Eve would not be too long as I was keen to be with Mandy, not her... We chatted small talk, and as I returned my tea cup to her tray (invitation to leave Eve!) she leaned forward and with dressing gown gaping to reveal her right breast and pronounced nipple, ran her hand up Mandy's leg to her knee, saying it was great we were spending intimate time together - and me thinking it would be truer still if she departed! My mental request was ignored and Eve unfastened Mandy's dressing gown and she squealed in delight as she saw the cheap Anne Summers lingerie with Mandy's nipples protruding with lipstick on them. Eve became more dominant, instructing Mandy to kiss me before kissing my chest running her lips down to my 'cock' as she called it....and take her in her mouth. I responded by placing a hand around Mandy to steady her being around by this new situation as she took me in her mouth. Eve with a gaping dressing gown watched intently, now running her hands in/out of her dressing gown over her own breasts... Mandy enthusiastically sucked my cock but was inexperienced, and I would rather have been fucking her. The saving grace was the fantasy situation I now found myself in. Eve was by no means unattractive...I pushed Mandy's dressing gown off her shoulders opening her gown as she paused to kiss me for a moment. On doing so Eve leaned forward and taking my cock in her hand wrapped her lips around my now throbbing cock and the sensation was heavenly as she worked the most sensitive parts of my cock like an expert as she virtually sucked the sperm out of my balls as I surrendered to a real woman desperate to drink my seamen. Asking Mandy to lie back and 'make herself feel good' she sucked harder then kneeled and removed her dressing gown showing a taunt, but full body with full (but not massive) breasts but large engorged nipples with trimmed and shaped public hair - she ran a hand across her nipples and down to her vulva instructing me to enter Mandy. As I entered her she was even wetter than before also already lubricated with my sperm and Eve lay alongside us now alternating between pinching her nipples and running a finger down to her clit. I started thrusting into Mandy when Eve lay on her back asking if she could taste? Mandy smiled and indicated I should withdraw and on doing so I knelt between Eve's open thighs with her thicker, deeper, trimmed vagina looking very inviting as Mandy gestured to me to enter her which I did. She was nowhere as near as wet as Mandy, but I felt her grip my cock and really grind her clit against me as a timidly entered her only to find her hands on each of my buttocks pulling me in as she absorbed my cock, kissing me as her legs wrapped around my ass...Mandy kissed me as she did it and she encouraged me to cum...which I did wishing I could play more with Eve. I waited until Eve had cum as she stiffened, before feeling able to cum myself with Mandy's encouragement and I felt her legs open a little to receive my warm cream which she savoured with her eyes close.. All 3 of us laid together for a while, and eventually in the early hours, Eve arose leaving Mandy and me in bed together as I watched her get out of bed and slip her dressing gown on again, kissing us both as she left. I awoke in the morning believing it may have been a dream after Mandy had demanded another fuck. On reaching the kitchen Eve was friendly as she managed the children, asking if I had slept well and Bob reappeared at lunchtime, tired but jovial from his overnight fishing trip. As I prepared to leave I went to thank my hosts, have a lingering goodbye with Mandy. Eve gave me a polite peck on the cheek and Bob offered to drop me at the station -we shook hands and his parting comment was - 'I'm sure you will be welcome again as you are Eve's type!' I suspect he knew...and as I returned to school, unlike our normal conquests, I did not mention it!
