I went back to my chair, which I pulled back from my desk, and sat down, lolling at full stretch, relaxed and contented.
Dot emerged from her hiding place. I hastened to cover myself up, not having bothered up til then to do up my trousers.
"Please, not on my account," said Dot, "After what I've just seen and heard, the sight of your equipment is no big deal -- literally and metaphorically at the present time!"
"Thanks a lot!," I said, "But seriously though, that really was something else! Thanks for setting it up for me, I really did think that I had gone past the days of such delights."
"Actually you were very good -- I didn't know you had it in you."
"I didn't; I had it in Lisa -- her mouth anyway."
Dot said, "I am going to be serious now. The little exhibition you and Lisa put on has made me very randy. As I intimated at lunch time, it has been a long time for me since I had some good sex. We've been friends and colleagues for a good many years, but I want to cross a Rubicon with you now which is going to change things between us. I am past the age when I need to worry about pregnancy, so will you give me a good hard fucking?"
"Dot, I would love to!," I said, "Come here and give me a kiss."
She came towards me and leant forward; our lips met in a warm and gentle lingering kiss, and I felt her hand stray down to my cock, which was starting to harden up nicely again.
She broke away. "I am quite intrigued by your s & m idea. I've never been punished like that. I took my knickers off to frig myself while you were dealing with Lisa, so now I'm afraid I'm improperly dressed and you will have to spank me, too."
Without more ado she walked to my right side, then stretched herself over my knee. Hoisting up her skirt and exposing a rather more ample rear than Lisa, but nice and rounded nevertheless, she said, "Just the palm of the hand in the first instance, twelve times, like Lisa. But don't hold back -- I'll tell you if you are over-doing it. I want to see if a little pain really does enhance the fuck that follows"
Well, a gentleman always agrees to do what a lady asks, so without warning I started to spank her with some energy, each buttock alternatively, without pause, bringing a nice red glow to her arse.
Dot gasped with each blow, and her language took on a certain coarseness. Between gritted teeth she said, "You bastard, you'd better fuck me properly after this!"
After being spanked, she got up and took off her blouse, then undid her bra, allowing her ample breasts freedom. She thrust forward to my mouth saying, "Suck these tits, and don't be gentle!" I sucked hard and chewed on each nipple in turn. Her arousal was getting to me.
"Bend over that desk, bitch, I want to taste your cunt, and then I'm going to fuck you like sex is going out of fashion!"
She did not hesitate, but turned and bent over the desk, spreading her legs, and bringing her hands behind her she hoisted up her skirt and separated her arse cheeks. I knelt behind her and grasped her thighs, pulling her cunt towards my mouth, I sucked hungrily on her outer lips and then went searching for her clittie with my tongue. I sucked and nibbled on her clitoris, then lapped eagerly on her cunt and up to her arsehole and back. Judging by the very animal sounds coming from Dot, and the way she was thrusting her arse at my face, she was very turned on.
Before long she was demanding, "Fuck me now, you bastard, and do it properly!"
I stood up, moved close to her arse, and pushed my cock hard into her waiting cunt. I reached forward and pushed my hands round her to grasp her breasts. She raised herself up somewhat off the desk, saying, "Pinch my nipples while you fuck me!"
