You will have gathered, assuming you have read part one, that Jean and I, lovers for a while, like nothing better than to fuck - as often as we can, in as unusual way as we can, and with great relish and enjoyment. Our opportunities are restricted, because Jean's husband gets in the way, and so a quick lunchtime meeting is usually all we manage. Occasionally, we can spend a morning or afternoon together, but such events are rare.

After a lunchtime quickie, we were enjoying a cigarette and talking about the place where I used to work, and where Jean still worked. The conversation got around to Pam, a colleague of Jean's. Pam was as fat as Jean was slim, and from all she had said, Pam hated sex as much as Jean enjoyed it. In fact, Pam lived only for the day when her husband, Norman, was too old to make demands on her. Jean was saying how rough this must be for Norman, and what a lot of enjoyment Pam was missing, and without really thinking, I said:-

"You should invite her round, one day, and we could have a gang-bang!"

This was hardly a remark of great wit, but for some reason, it amused Jean mightily, and she could not stop laughing. When she laughed, her tits just trembled, very slightly, in such a sexy way that, in spite of cumming twice already, I could not resist her, and rolled on top of her. This stopped her laughing, and, well, you can guess the rest. Anyway, I forgot all about Pam, and Norman, and concentrated on our third cum of the session.

Some weeks later, we had a rare treat. We could manage a whole morning off, together, and I was determined to make the most of it. As soon as I arrived, I declined coffee, a cigarette, anything, and pulled her in the direction of the bedroom. I undressed in seconds, and lay on the bed, watching her undress in a more leisurely fashion, enjoying the slow unveiling of her lovely body.

She had a way of undressing which was fascinating. There was no hint of intentional flirtatiousness about it - she removed her clothes in a natural, almost casual way, but I found it intensely erotic, whether or not she meant it to be. When she was down to the bra and panties stage, standing in the middle of the room and surrounded by discarded blouse, skirt, slip, stockings, suspender belt and shoes, she stopped, as if she had just realised I was watching her intently.

"Close your eyes," she said, and I did so, happily. There was a rustling noise, I felt the bed dip a little as she climbed on, and then something - I knew it was her nipple - was pushing its way into my mouth. I opened my mouth wide, trying to take in the whole breast, and just as it seemed I might succeed, the doorbell rang!!

"Shit!" I exclaimed.

Jean pulled away from me and stood up, taking a robe from the foot of the bed.

"Won't be a moment, darling," she said. "It's probably only the postman." She left me, and I heard the front door being opened, and then voices. After about five minutes, she returned.

"Darling - we've got a bit of a problem. It's Pam. She's in the sitting room, waiting for me - and you!"

I got off the bed, panicking slightly. I grabbed a dressing-gown I could see hanging behind the door - Jean's husband's, presumably. There was nothing I could do about my considerable erection, so, bent over slightly, I went into the sitting room. Jean and Pam occupied the arm chairs, facing each other. Pam was fully dressed, of course, and Jean wore her robe. I sat on the settee which was placed between them.

"Hello, Pam!" I said, trying to be nonchalant.

"Well," she said in reply. "What have we here. The two of you seem to have been caught in something of a situation. Have you anything to say?"

Before I could say anything, Jean spoke.

"We don't need to say anything. Yes, we admit that we have been enjoying each other and sex - we have been for some time. But that's no sin."

I opened my mouth to join in, but Pam got there first.

"Well, I'm not sure that J and K (she used the name of my wife and Jean's husband) would agree it was no sin. Anyway, provided we can agree a price, there's no reason for them to find out."

"What price..." I began.

"You're not going to blackmail us!" Jean spat out. "I'll go through a divorce before I'll pay you a penny!

"Now just.." I tried.

"Pennies weren't what I had in mind," Pam replied.

"What do you wa..?" Me, still trying, but interrupted by Jean.

"I think you'd better leave, now!"

"Let's just calm down," said Pam. "Just let me tell you what my price is. You never know, you just might be prepared to pay!"

"Never," began Jean, but I went over to her and put my hand lightly over her mouth.

"Just be quiet a minute," I said. "Go on, Pam."

"Well," she began, thoughtfully. "I guessed a while ago you two were lovers. I also guessed when you would see each other. That wasn't hard, knowing your time-table, Jean. And the last time you met, I had it worked out, and came around. I heard you crying out, Jean, and it wasn't in pain. It was in pleasure. Real pleasure! That's something I've never felt in sex. In fact, I've always hated it. So I thought, if these two can enjoy it so much, perhaps they can show me how to. So that's what I want. To share a session with you both."....(cont)
