Sarah had always loved to be spanked. Any previous boyfriend who didn't deliver her the spankings she sexually demanded didn't last long. She had been with Max for over six months and spanking was a vital part of their sexual relationship. Max was reluctant at first to admit how much he enjoyed spanking women and in particular spanking Sarah.
On the evening in question Max was desperate to create havoc with Sarah's bottom. He had been away for over a week and had abstained from masturbating the whole time. Sarah was unaware that Max had planned a surprise for his 24yo girlfriend. He knew it was a very risky surprise but Sarah loved surprises and had always enjoyed the variety in their sex lives.
Within a minute of her arriving at his spacious house they were both naked and she was across his knee. They didn't need any other foreplay, as this was the way they loved to start things off. The first dozen were delivered with no great force. Without saying a word Sarah moved off his lap and knelt between his legs to take his erection into her mouth. At this stage she knew not to use her hands on him or to masturbate herself. She licked him only occasionally taking his purple head into her warm mouth. She would judge when she had got him excited enough but without any risk of bringing him to orgasm. This was quicker than usual but that excited her.
Back over his knee the next dozen were delivered with more force and did start to change the color of her tight cheeks to a shade of pink. When she dismounted this time she knelt on the sofa next to him facing the back. Her back was arched in an attempt to offer him as much access to her pussy as possible. Max was not surprised to see that her pussy lips were redder than the cheeks of her ass with her arousal more evident than usual so early in the spanking. His tongue found the wetness and made sure it was spread from her clit to her anus. His mouth was gentle and not too demanding but elicited a beautiful sigh of arousal. Sarah loved this slow build up. They both knew when it was time for her to get over his knee again to receive more spanking. As usual the third set of spanks was harder than the previous two. The heat would start to spread from her cheeks throughout the whole area as each blow landed. Sarah knew that the painful heat of her bottom and the arousal of her pussy would melt together and she would start to zone out slightly. As she once again climbed off his lap she sensed something had changed and looked towards the door behind her and was shocked to see Max's father. He was naked, a smile on his face and an erection.
It was his erection that despite her surprise she studied. She had expected to see that it was huge but due to the fact that it was pointing directly at her she could only really see the large head. She had expected it to be huge because it was a game that Max had played with her on many occasions. He would repeatedly get her to the edge of orgasm but deny her. He would then either tell her that his father was going to fuck her with his huge cock or require her to tell him that his father was fucking her. Due to the timing and or the fantasy Sarah always orgasmed immediately. What was happening now however was taking involving Max's Dad to a completely different level. She was concerned just his being there might trigger her to orgasm just as the fantasy had always done. As Bert (Max's Dad) walked towards her she did get a better view of his bouncing erection. It was a good size but not the monster that it was in her fantasies.
"What a wonderful sight. Your bottom always looks beautiful my dear but reddened and bouncing as it is right now it is exquisite. Max did say that I could watch but I was rather hoping to be allowed to do a little more. If I am not mistaken you were just about to take my son in your mouth again. Please don't let me interfere."
With this he sat next to his son, his erection matching Max's. Sarah was desperate to mount the older man's lap and receive his erection but resisted. Instead she knelt and took Max's straining cock in her mouth. Even as she did this she maintained eye contact with Bert who she found completely mesmerizing. Max was delighted that Sarah had welcomed his father so happily. Sarah sensed that Max was very close to cumming very quickly. She had a decision to make but it was not one that she wrestled with for long. She did fleetingly look up into Max's eyes to check that he was not going to prevent her involving his Dad. There was no such reaction and Bert's cock was soon feeling her warm mouth enveloping it. It did take a couple of minutes to get Bert to the point that he thought he might explode but she knew just what she was doing. She challenged Bert with her gaze as she asked,
"Are you going to spank me then? I need to be spanked hard now and then fucked into tomorrow."
She was over his knee in seconds. Max had remained where he was and was delighted that after a little maneuvering her mouth found his cock again. The spanking was very firm as Sarah wanted and each time his hand landed her mouth closed harder on Max's erection. After a dozen or so Bert paused and caressed the beautiful now glowing cheeks before teasing his middle finger very close to anus. Her reaction was to try and make his finger find the center of her tight orifice. He teased her getting closer and closer each time before removing his finger.
"Are you as anally excitable as Max says you are? If you are I would be delighted to pay your tight little anus plenty of attention. How does that feel my dear?"
"Fuck that is so fucking sexy. Please don't stop I could lie here all day and let you finger my bottom."
