Gwen Thompson had made plans for her fortieth birthday. They did not include being taken from behind with a large strap on, by her deputy and friend Rachael. Nor did they include being gagged with a double sided penis gag. The smaller, three inch long and two inches in diameter, was strapped in her mouth. The seven inch by two and a half inch diameter realistic phallus on the other side was buried in the pussy of Saskia Conroy, and Gwen was busy moving it in and out for all she was worth. Each partial withdrawal impaled her on Rachael's strap on.

She was still bound in the armbinder that she had worn since 7 pm the previous evening and she had to continue to wear for yet another hour. She had fond memories of the previous night, though not of the six strokes of the tawse that she had received. The time in the penthouse had more than made up for that. She now knew that she was a bondage slut, she felt so good in bondage. She also loved the latex clothing that she was wearing, even though it was now soaking wet with her sweat. She had loved being fucked by David and then Andrea and eventually Saskia, Irene and finally Rachael. She had known for some time that Rachael was bisexual and now she knew just how passionate Rachael could be. She also knew that Rachael could give her a lot more enjoyment with a strapon than the other girls had done.

Alongside her, Jill Anders was similarly bound and enjoying similar treatment from Irene Palmer, who was using the strap on, and Cordelia Van Heusen who was on the receiving end of Jill's double sided penis gag.

David Williams came in from the shower room and surveyed the scene.

'It's worse than Euston Station in here' he observed'

Andrea Margaron looked up from her tablet, where she was in the middle of a Skype call and looked at him quizzically.

'Large railway station in London' he answered her unasked question. 'Who are you talking to?'

'Your Mom', she replied.

'With this going on???' he yelled.

'She just rang. I can't ignore her!' said Andrea.

'Then take it in the other room. I have business with Gwen and Mum can't see that.'

Andrea smiled and left, though Elspeth Williams caught a literally sideways glance of the action'.

When she had left, David crossed over to Gwen 'My turn' he said to Rachael, who immediately withdrew as he climbed on the bed, took hold of Gwen's legs and pulled her towards him.

He wore a pair of latex jeans, from which his extremely erect cock was protruding. As she slid over the rubber sheet that had been put over the bed in the Master Bedroom, she exited Saskia's pussy, at which point Saskia also vacated the bed. He rammed his cock into Gwen's pussy and she climaxed almost immediately. He took his time allowing her three further orgasms before he took his own. He slumped on top of her and lay there for some minutes, his cock still inside her. Eventually he lifted himself on his elbows and kissed her latex clad breasts and her gagged mouth. 'I'm glad you joined us Mrs. Thompson, Happy Birthday!'

Despite her hopes that time would stand still, 8 o'clock arrived and her bonds were removed. She was then told to shower and get dressed. Although she was offered any clothes that she wanted, she insisted on a similar latex dress and latex underwear to those she had worn the previous day. 'I loved the feel of latex next to my skin. I'm not sure I'll ever wear anything else, ever again.'

'You will if I tell you too' said David 'but it will have to be for a very good reason. I adore women in latex, leather or PVC.'

While she was getting dressed and putting on her makeup, Jill Anders came in to thank David for the previous night. In particular she wanted to thank him for going easy on Gwen with the tawse. 'I'll gladly accept the remaining lashes whenever you wish.'

'That won't be necessary. You earned your reprieve by helping me see Gwen through those lashes. I didn't want her to volunteer in the first place but once she had done, it would have cost more in her loss of morale and motivation if I had turned her down than simply delivering the six lashes. I need Gwen to be a key member of this company, just as I need you. The two of you have bonded and you both have tried to help the other, even if it means accepting pain. I'm proud of you both.

'Thank you Boss' came a voice from the door. They both looked round and say Gwen, made up and ready for work. 'And thank you Jill. I think I've gained a good friend.' She came over and kissed Jill full on the lips and then repeated it with David. 'It did hurt too, I think I need to work on that side of being a slave, otherwise I can't join in your games in the Playroom, to the extent that I want to.

'Gwen, you'll never be a masochist like Cordelia or Rachael, so take it easy. But I am impressed that you want to try. For now though, relax. The sight of you bound in latex presses all the right buttons, for me so you don't need to do any more.'
