Dan was in a world of his own until he noticed a guy walking over to their car. The guy was massive. Easily six foot six with huge muscles and what must have been an erect ten inch plus cock . The man stared Dan in the eyes. He had a mean look on his face. In fact he looked utterly mean. Dan was scared. Something about the way the man looked at him made him incapable of protesting.
Without a word and in one swift movement the monster lifted Shelly's skirt and inserted himself into her wet pussy. Shelly had not noticed the man approaching and so was completely shocked. She immediately stopped sucking Dan's cock. His cock was still in her mouth but she was gasping, she appeared to have forgotten all about Dan's shrinking manhood. As the man began to push his huge cock further into Shelly she began to get a little breathless. He breathing became short and fast. He stated to move his cock in and out of Shelly's stretched vagina. Dan saw that her eyes had lost focus and she began to moan as only Dan had ever heard her moan before.
After a minute of gentle sex the man finally got his full length inside Shelly. She was so full that his cock rubbed hard against her clitoris every stroke. He picked up pace and Shelly's moans got louder, more guttural and more frequent. Dan had never heard her this worked up. His own cock was only half solid now and he was already racked with intense jealousy. He knew he would never be able to recreate such a huge encounter for Shelly and she was obviously loving it.
The guy did not just have a huge member, he knew how to use it to. He had a rhythm, moving between slow and gentle through to hard and fast. Just the right duration of each to make Shelly go crazy with lust. All of the time the man did not take his eye's off Dan. It was as if he knew that this was not what Dan wanted but he was taunting him, daring him to try to make him stop, knowing that Dan was too pussy to do anything.
After about five minutes Shelly began to feel her most intense orgasm ever starting. Her breathing became more laboured still. The man's cock was getting more soaked by her juices. Shelly felt a burning fire start in her pussy and suddenly explode through her body, causing her muscles to spasm. Oh god, this was good. She was vaguely aware of a familiar voice.
'AAAAGHHHHH, FUCK.' Mid orgasm Shelly had bit down hard on Dan's half hard cock, forgetting it was in her mouth still. She was so into her wave after wave of pleasure that she did not stop biting until she had to moan again and she certainly did not stop the magician who was inside her. She just opened her mouth so Dan's cock could fall out and gave it not a single thought.
'Oh god that was good' Shelly murmured as the stranger continued to pump her. He was not ready to cum yet.
'You're so big. I feel so full. This is amazing. I have never felt like this. Oh god you are the best ever. I didn't know it could be this good.' These were some of the things that Shelly said to the lover she had not laid eyes on. Every single one of her comments drove a dagger through Dan's heart. What had he done? Why did he suggest this? His cock was agony and bleeding but he dared not move. The stranger had him completely intimidated. He just had to sit and watch him fuck his wife senseless whilst she was bent over Dan's knee.
Shelly felt her second orgasm coming. It was more intense than the last. The strange cock was relentless in its task. She never wanted it to end. Her spasms were stronger and she was screaming at the top of her voice as same came. Dan noticed a lot of liquid suddenly flowing down the guy's leg and realised that he had made Shelly squirt for the first time in her life. Then he saw the man's body stiffen as he forced his cock as deep as he could into Shelly. Dan knew he was emptying his seed into his wife's womb. It seemed to take forever. How much cum did this guy have?
Once he had finished he pulled out, pulled his pants up and walked off without a word. Shelly lay there for a few seconds more before getting up and walking round to the passenger side and getting in. Dan pulled his pants up. His cock was still bleeding a little and was so sore he could almost not stand it. He drive home in silence until...'Oh my god, that was the best sex ever. He was just so big I could hardly breath. If you made me feel like that I would be on you every day. Hell, what am I saying? I would be on you five times a day.' Dan sat silently. A different empty feeling in his stomach.
Over the next eight weeks things had been a little distant between Dan and Shelly. It was only two weeks ago that Dan managed to take a piss without being in total agony. It still stung but not as bad. He had been unable to have sex with Shelly but then she had not seemed in the slightest bit interested in Dan sexually since that night. Dan had even found a massive vibrator and knew that Shelly now had a taste for big and he did not cut it. He really regretted ever suggesting trying dogging but he had never expected it to turn out like it did. He was feeling so low and then the bottom completely fell out of his world. Shelly got home and said in a very excited tone, 'Honey, I'm pregnant.'
What had he done? Why did he do it? His life was over. He would never know whether the stranger was the father. Although in his heart he would always believe that that the stranger was the father. After all, Dan had unprotected sex with Shelly for five years and nothing happened. Then eight weeks after the night with the monster cock emptying inside her she is eight weeks pregnant.
