Catherine and Jamie were married but not to each other. The affair had been going on for nearly two years. It was purely a sexual relationship with increasingly bondage and spanking being at the heart of nearly all their time together. Both liked to be both recipient and supplier to each other. Catherine's other regular lover was always very meek and gentle.
Today they knew that they had plenty of time to enjoy each other. They immediately went to the bedroom and with the minimum of discussion it was agreed that Jamie would tie Catherine up and they would both enjoy the domination. They didn't need to discuss the safe word, as it was always the same.
Jamie put a pillow over the, nearly waist high, rail that ran across the bottom of the bed. Without being asked Catherine draped herself across it and reached her hands up towards the top of the bed. Jamie tied her hands stretching them to the corners leaving her feet on the floor, bent 90 degrees at the waist. He then attached her feet to the corners of the bed near the floor. The finishing touch was a blindfold.
"I know how you love to be helpless and teased until you explode. I thought tonight I would treat you to a fantasy that you have shared with me a number of times. I will tell you more in a few minutes."
With this he caressed her naked bottom using just his fingertips. He reached between her legs a couple of times, laughing at how wet she was already. It was as he was laughing that his phone bleeped.
"Oh right on time. I know you are not really dressed for it but I thought you would like to meet an old friend of mine. Please don't dress I am sure he will be delighted to see you just how you are."
"Jamie don't you dare let anyone in when I am like this. You bastard come back here right now."
He was nearly at the front door by the time she finished cursing him.
"Now, my friend will not say a word but I have told him what is off limits. Which is not much really.
"Get him out of here or you will regret it. This is so humiliating."
"It would be you who would regret it if he left now. You love to be humiliated, do you remember that party when your husband was away. You loved being the centre of attention. It was your first multiple. Tell you what I will give my friend five minutes. If you are not dripping I will show him out."
"You really are a bastard aren't you? You know damned well I will be dripping in five minutes."
She felt cool hands spread the cheeks of her bottom and blow gently on her dark crinkled anus. The tongue that followed was so gentle she was not sure what was touching her. Jamie had never done this to her and it was so embarrassing. This was made worse when she let out a deep moan of pleasure. The tonging was not quick but was mixed with occasional visits of the tongue to her pussy. She pushed back to let it reach her clit. The tongue was removed and there was movement around the bed.
"Would you like my friend to leave my love?"
"You bastard of course you know I don't"
"I think you have just been give a free pass to do as you want with her. I shall just sit back and enjoy the view and I am sure the sounds. Catherine is a rather noisy lover. Aren't you dear?
A grunt was all that he got as an answer. A further grunt escaped her lips as her nipples were gripped firmly between fingers and thumbs. Catherine listened hard to try and sense anything that would help identify her assailant. When lips nibbled at her ears she was sure that scent or sound would give her some help. She could not smell anything and the breathing was no help.
