Sam and Marsha had been married for many years more than Sam's brother, Mike and his frigid wife, Tina. Both couples lived next to each other in a upscale rural neighborhood. The lots were large, five acres each. So, there was plenty of room between their houses. Both men worked in the family businesses, farming, fertilizer and a car lot.
Mike was reserved. And, Tina was just a downright cold fish. They had been trying to a have baby for two years and were unsuccessful. The doctors said that Mike's sperm count was low, but that he could conceive. Mike's biggest problem was his short dick. He just could not deposit his sperm deep enough in Tina's pussy to do any good. Mike and Tina were desperate to have children.
Robert, Sam and Mike's father, was very wealthy, but not inclined to be generous unless he got something in return. If Robert could, he would take his money with him when he died. He had said on many occasions that if Mike and Tina did not have children, then he would write them out of his will. Robert was the kind of person who would not accept adoption. His heirs would have to be his own blood, not some stranger that he was not related to by blood. Robert's old fashioned ways set a lot of by blood kin. Thus, the reason for Mike and Tina's urgency.
Sam and Marsha had two children and had satisfied Robert's demands. The pressure was on Mike and Tina. Robert had become so demanding that Mike had trouble performing on occasion. Tina, being so frigid, did nothing to relieve Mike's stress. Mike and Tina had tried artificial insemination to no avail.
One Saturday afternoon Sam and Marsha were invited over to Mike and Tina's for steaks and drinks. The sun was hot and Mike made pina coladas. The thing about pina coladas is that they sneak up on you from behind. One minute you feel fine. The next minute you are plastered. One a hot day like this, they go down smooth and cool. You cannot seem to get enough.
After the steaks and six or seven drinks, Mike and Sam were sitting by the pool when Mike brought up the subject of getting Tina pregnant.
"I don't know what we are going to do. If I can't get Tina pregnant, Dad will cut us out of his will." Mike said.
"Well, I wish that I could help." Sam sympathized.
"Dad warned us that he will not accept an adopted child. He told me the other day that we not to think about using a sperm bank. He wanted his own blood to inherit his money and no one else. You know how he is about blood kin. I am afraid that he will demand DNA test if Tina has a baby." Mike said. He was beginning to slur his words.
"I'll help you in any way I can. Do you want me to talk to Dad? Maybe I can get him to listen to reason." Sam said.
"Would you?" Mike said.
"Sure, I'll talk to him." Sam replied.
"NO! I don't want you to talk to him. I want you to help!" Mike was beside himself.
"What can I do? I'm no doctor. What do you want me to do? Fuck her for your?" Sam said in an offhand kind of way.
"YES!" Mike nearly shouted.
"What? You can't mean!" Sam was stunned.
"Yes. That is exactly what I mean." Mike said.
"You are drunk. You want me to fuck your wife and get her pregnant. Shit, I don't even like her that much. She is too stuck up." Sam was shocked at the suggestion.
"Yes. I am drunk. I have to be drunk to ask you to do this for me. It would be perfect. Our DNA would be close. If Dad found out, his grandchild would be blood kin to him. It is the only thing we can think of. Marsha doesn't need to know. No one needs to know." Mike pleaded.
"Well, I don't know." Sam was thinking. Tina had a tight body. Five foot five. Nice tits. Broad round ass. A little strange pussy didn't sound too bad. It might be fun. But, Tina wasn't much fun. She didn't have a sense of humor. Maybe a good fucking or two would loosen her up.
"What does Tina think about this." Sam wondered.
"She doesn't like it. But, she doesn't want to be cut out of Dad's will either. You can do this. Do it as favor for me. Once she is pregnant, it we don't do this again." Mike pleaded.
"Okay. I'll do you this one favor. But, don't ask me to do anything else." Sam said with a smile. Mike was too drunk or nervous, or both, to see the irony of the situation or the lust in Sam's eyes. He took Sam seriously. What a dork!!!
"Great! I'll tell Tina to expect you. Think of some excuse to get out of your house and slip over here tonight." Mike said.
In the meantime, Tina had been shoving pina coladas to Marsha. By the time the party broke up at 8:00, Marsha was ready to go to bed. Sam and Marsha walked across the lawn to their house. When they got there, Marsha took a quick shower and jumped in the bed. She was asleep when her head touched the pillow. Sam used the opportunity to return to Mike's house.
Sam entered Mike's house by the back door. He is not bother to knock. Mike was in the living room watching TV. "Now what?" Sam asked.
"Tina is in the bedroom waiting for you. We thought Marsha would pass out as soon as she got home. Go on in." Mike said.
Sam walked slowly down the hall to the master bedroom. She slowly opened the door. He was not sure if this was a good idea. But, Tina had a tight body. He just had to have some of that.
The room was dark. The light from the opened door allowed Sam to see Tina lying in the bed with the covers up to her neck. "Tina are you sure about this? I can go back home." Sam asked.
"I am sure. I want you to get me pregnant. We must have a baby. If the baby is from you, then Mike will feel better because it will be like his own flesh and blood. Just remember this is just sex. Nothing more. Once I am pregnant, we forget this ever happened." Tina said with a trembling voice.
"Anything you say." Sam said quietly.
Sam shut the door leaving it open just enough so that the light from the hallway allowed him to maneuver around the room without tripping over the furniture. He shed his clothes in a second and crawled into the bed next to Tina. Sam reached over and touched Tina's arm. Tina instinctively pulled away. It took her several seconds to return to her original position and allow Sam's hand to remain on her arm. But, she was still trembling. Sam slowly stroked Tina's arm until she began to relax. Then, he gently eased his hand over to her right tit and let his fingertips explore every inch of her slow skin. As his fingers crossed her nipples, he found them hard and sticking out.
Gently, Sam's fingers investigated up to Tina's right shoulder, across her neck to her left shoulder and down to her left breast. Tina was still nervous. Several times Sam touched a sensitive spot that made her whole body twitch. As Sam's hand moved down to Tina's left breast, Sam's body descended on Tina's right side. Without her noticing it, Sam was laying halfway across Tina.
