Chapter 3

A few weeks had passed and mark was getting laid on a regular basis. The whole family seemed to have grown closer. Though Mark's mom Susan did not no he was fucking her lovely daughters. He planned on letting her in on it sooner or later.

On Monday Susan reminded Mark that it was time for his annual check up. That made him very happy because he got to see Dr. Joan Tayler. She was a knock out. She had long black hair and beautiful brown eyes and even though she wore that long doctor's jacket he could tell she had a killer body.

Susan drove him there at around two o'clock. They had to sit in the waiting room for 30 minutes but that was OK. What Mark had in mind was worth the wait. He had a nice surprise for the Dr. when she grabs him by the balls and asks him to cough.

He finally got in to see her and the minute the were in the room he started messing with her symbols making her a little horny. He did not want to over do it yet. He could tell she was getting a little flushed. Every time she looked at him she just kept getting hornier and hornier. Then when it was time to make him cough she grabbed him by the balls gently and said "Cough." And Mark did. Then with a look of lust in her eyes she moved her hands from his balls to his cock and said "I know I can make you cough... But lets see if I can make you cum." Her voice was husky as she said these words.

She let go of Mark and quickly removed every last stitch of her clothes. Mark then removed the rest of his clothes and said "No... Lets see if I can make you cum." She lay down on the examining table with her legs spread. Mark leaned in and gently licked her slit. "ooohhhh" She moaned. She started to moan louder as he darted his tongue in and out of her wet cunt hole. "AAAAHHHH" She let out.

Then Mark went for that nub of flesh that gives so many women pleasure. He sucked and licked at it causing the good doctor to wrap her legs around Mark's head. "IIII'MMM GOINGGG TOOO CUUUUMM." She moaned in a loud voice.

She then began to buck and thrash around wildly. After her first orgasm Mark stood up and placed his rock hard cock at the entrance of her pussy. All the doctor did was look at him with lust craved eyes.

Mark then rammed in as hard as he could. "AAAHHHH" The doctor moaned out. Mark began to pump in and out as fast as he could making the doctor moan continuously. Her whole body was flushed and her legs were wrapped around Mark's waist tight.

Mark felt his cum boiling inside of him as he was pumping. He was almost there and could tell she was almost there to. He started to pump at lighting speed and he was beyond the point of return. He felt his cum shoot from him like from out of a fire hose.

When the doctor felt his seed splash the inside of her it sent her of on another wave of orgasms. "IIIII'MMM CUUUUUMMMIING AAGGAIINN." She yelled out as Mark was pumping the last of his hardness away.

After they were done neither of them spoke a word as they got dressed. The doctor walked out of the waiting room and up to mother Susan. "So is he in good health?" Susan asked the doctor. The doctor blushed as she said. "Yea, I would say he is in perfect health." Mark winked at her as he walked out the door. On the way home Mark had decided to let Susan on the fact that he was screwing both her daughters. But he was going to do it a special way. He decided that him, Susan and Heather would have a three way and then tell her he was sleeping with them before that.

When they made it home he knew Vic would not be there. She was at practice. Heather was sitting on the couch watching the tube. " So what did the Doc say?" She asked. Mark got a dead serious look on his face and said "They said I have aids." Heather got a look of horror on her face and that was when Mark busted up laughing.

Heather on the other hand got so furious that Mark thought steam was gonna come out of her ears. Apparently she did not like that little joke. She flew off the couch and gave him a round house kick to the gut. Hard!
