Swingers stories and erotic fantasies

My girlfriend has always refused to indulge in a threesome despite being aroused at the idea. We have talked over various possible scenarios with various people and although we end up shagging like rabbits afterwards she has said she would never go through with it.
Recently a sales rep from a new company has visited her at her shop and been paying her compliments. His visits have become more and more frequent despite her lack of orders.
She has told me everything that has been said and has admitted that she found him very attractive.
He is very tall (6ft 6!!),dark and Italian looking. I on the other hand am 6ft and blonde. She has always had a thing for very tall guys and likes anything vaguely Italian.
Last week he called in lunchtime when she was on her own.
They chatted for some time until her assistant returned whereupon he soon left.
Later that day at around 4.30 he returned bringing coffee and cakes with him.
They were all laughing and the time went quickly. He was brushing against her and she said she found herself being unusually flirty with him when her assistant wasnt listening. This is quite out of character for her.
At 5.00pm her assistant left to go home leaving them alone.
She said there was a kind of tense silence as she locked the door with him still inside. He had made no attempt to leave.
As she turned from putting the metal guard on the door he was stood behind her.
He pulled her back towards him and she found herself giving in to him.
She hesitated for only a second or two.
He smiled and she relaxed a little. He turned his face towards hers,she opened her lips slightly and they snogged passionately.
He gently nibbled her neck and ran his fingers through her long blonde hair.
Taking her by the hand,he led her to the back of the shop and moved her backwards,up on to the edge of the rear counter. They were still snogging as he stroked her thighs then raised her skirt upwards. When it was almost up around her waist he knelt down in front of her. He kissed her thighs and licked at her pantie clad mound. Still slightly dumbstruck she said he drew her panties to one side in one swift movement and kissed her shaven pussy. She gripped the counter edge and further parted her thighs. She said his wet tongue lapped firmly at her pussy lips before slipping inside her with strong movements. She was gasping with the shock of it. One of his hands held the material of her panties,the other carressed her bottom. She felt his fingers exploring between her buttocks and she slid from the counter edge to allow him more access.
Within minutes she felt her orgasm building.
As he continued to suck and lick her she shook and came. Her knees weakened and she could barely stand. Her juices spread all over his chin and cheeks as his tongue pushed itself in to her.
He then stood and undid his trousers. She was still panting and flushed as she watched him pull his trunks down to reveal his rigid cock.
Mine is average length and quite thick. I also keep my hair very trimmed.
She told me he had a full bush of black hair around his cock,the thing itself was longer than mine and whilst not as thick it did have a very large round hard red head.
He helped her from the counter and after more snogging he urged her by her shoulders to the floor in front of him.
In one movement he slipped his cock in to her open mouth.
(She has only had oral sex with me and a previous boyfriend. I am also the only person who has cum in her mouth.)
As she took his cock further in to her mouth she said it pulsed on her tongue.
She said it tasted salty and the head filled her mouth,cheeks and throat.
He gently but firmly slid in and out of her mouth as she sucked and tried to use her tongue on the head and shaft.
He quickened ever so slightly then slowed again and started to groan.
As he held her head in front of him his movements ceased,the head of his cock was at the back of her mouth. She said she felt it twitch and throb for a second then he shot warm spunk down her throat. She gulped and swallowed as he moaned and emptied himself.
He slipped slowly between her lips giving her time to breathe.
She sucked the remaining liquid from in and around his cock.
Eventually,he helped her to her feet.
She said she had become aroused again and felt herself become even wetter. She expected him to fuck her there and then. She fully admitted that he could have done anything to her and she would have let him.
They kissed and cuddled for a time but then he told her he had to go.
She was surprised but he told her he would be back the following week at the same time.
He said that next time he wanted her to be without any underwear and he informed her that there would be no oral sex just pure fucking! Very direct.
She agreed and he left.
I picked her up from work and she related me the details later on that evening. We ended up fucking like never before. The thought of his tongue where my cock now was,the picture in my head of his plum red cock head between the lips i was kissing. Just wonderful.
We cannot leave each other alone and i am desperate for her to be full of him this week.
She has had moments where she has been unsure but i think she will let him do anything on the day.
Finally my sexy but at times prudish girlfriend has given in to the lust and passion we have talked about for so many years.
As far as i am concerned he has done me the biggest favour and helped our relationship no end.
