How Could This Happen

Cassidy felt her vaginal opening spread as Mike's cock head slid inside her. She involuntarily tugged on her bonds. "Wait, you said you were just going to insert the tip."

"I wanted to make sure my penis didn't dislodge during ejaculation."

"Well we certainly don't want that. I don't want all of this embarrassment to be for nothing. Fine, leave it where it is."

The eighteen year old felt his cock throb as he held the head of his dick inside his Mother's pussy. He couldn't believe that she'd agreed to this crazy scheme. The knowledge that he was about to impregnate his mom sent a ripple of desire coursing through him.

"Mom, are you ready to begin?"

Cassidy was anything but ready to begin. She was tied to her Son's bed, with the head of his dick inside her pussy, and she was about to let him masturbate until he filled her with his sperm for the purpose of making her pregnant. "What the hell. Let's get this over with. If your Father finds out about this, I am so screwed. Hell, we're both screwed."

Mike grasped his shaft and slowly began to stroke it. He knew this was wrong, but for some reason that he couldn't explain, the thought of having his cock head in his Mom's pussy was intoxicating.

Cassidy could feel the head of her Son's penis rubbing the inner walls of her vaginal entrance with each stroke. She felt shamed by what she was allowing him to do. But that desire to be impregnated was just too much to bear.

As Mike stroked his shaft, he leaned forward a bit. His cock sank another half inch inside his mom.

Cassidy felt the intrusion but decided to remain quiet. She tugged slightly against the tie, but other than that she didn't move.

Mike continued to rub his cock. His excitement increased with each passing moment. As he massaged his shaft, the young man began making small thrusting movements with his hips.

Cassidy felt the head of his penis moving back and forth inside her, but said nothing. She knew she should make him stop, but the feel of his penis massaging the entrance to her inner passageway was beginning to feel good. She lied to herself, and said that it was just instinctive movement, and not sex.

Mike gazed down at his mom. His desire to inseminate her began to turn into the desire to fuck her. He knew it was wrong, but the young man wanted to fuck his mom. He eased his body forward another inch.

Cassidy felt her vagina spread a little more. Once again she tugged at the tie around her wrists. "Mike, you're putting too much in. You are at least an inch past what we agreed on."

"I'm sorry Mom, but this position is a little uncomfortable," he lied.

"Then get in a more comfortable position."

Mike leaned forward until his left hand rested on the pillow next to her head.

Cassidy felt half of her Son's cock slide into her pussy. She'd stopped thinking in terms of penis and vagina. "Mike, you're in way too deep," she gasped. "I can feel your cock deep inside my pussy."

The horny college student released his grip on his cock and leaned forward until his lips were pressed against his Mother's trembling mouth. He gently kissed her as he sank his cock completely inside her fertile body. The head of his cock pressed against her cervix, and his balls came to rest against her bottom.

Cassidy gasped into her son's mouth as she felt her pussy open up for him. She tugged hard against the neck tie, but her hands wouldn't pull free. She was being fucked by her teenage Son, and there was nothing she could do to stop him. A small whimper escaped her lips as Mike pushed his tongue into her open mouth.

Mike withdrew his cock partway, and then plunged back into her receptive body.

Cassidy moaned as her Son began to fuck her. Without realizing she'd done it, she lifted her legs and wrapped them around her Son's hips.

Mike thrust into his Mom repeatedly.

Cassidy finally broke the kiss and whimpered. "Mike, you must stop. I can't let you fuck me. This is incest. It's wrong, and illegal."

The young man took his mother's right ear between his teeth, and gently bit down.

"Please, we must stop. This is incest, Mike. We are Mother and Son. You must stop." Her body began to experience a pleasure like she'd never felt before. She gripped Mike tighter with her legs.

Mike slammed into his Mom's twat again and again.

"Oh, sweetie, this feels wonderful, but we can't do this. I can't let my Son make love to me."

"But I want to make love to you Mom. I love you, and I want to make you pregnant with my baby."

"Honey, I love you too, but what we are doing is wrong." Her nether region trembled with lust as Mike continued to fuck her mercilessly. Cassidy knew she was lost. She had allowed herself to be placed in this insane position because of her need to become pregnant.

Now, because of her desires, she was lying flat on her back, her wrists tied to the bed, and her Son was repeatedly ramming his cock deep into her fertile body.

"I'm going to fuck you again and again, Mom. I'm going to cum in you until you are pregnant with my child. Your belly will be swollen with my child, not Dad's."

Cassidy whimpered as the first wave of her orgasm hit her. She pulled against the tie until the cloth dug into her bound wrists. "Oh, baby, this is so wrong, but I need this. This is so wrong, but it feels so wonderful."

Mike plunged into his mom repeatedly. His cock began to swell with blood.

Cassidy screamed as the full intensity of her orgasm hit her. Using her long legs, she clung to her boy with all of her strength. "Please sweetie, fuck Mama. Fill me with your seed. Knock your Mama up. Fuck me again and again."

Mike felt his balls churning. He was about to cum. His sperm was going to fill his mother's pussy. He roared as the first jet of semen left his cock and entered her pussy.

Cassidy thrust her hips upward as her son pounded her pussy. "Oh fuck, I can't stop. You're making me cum. My baby is making his Mommy cum. My Son is making me pregnant."

They ground together for what seemed like a lifetime.

Mike kept pumping his baby batter into his Mother's fertile body.

Finally they collapsed together onto the bed. They lay there gasping for air.

Cassidy looked up at her Son. She could feel the tie digging into her flesh. "Darling, what we did was wrong."

Mike lightly kissed his Mom. "I don't care. I love you, and I wanted to please you. I wanted to make you happy, and pregnant. I want to make love to you for the rest of our lives."

Cassidy smiled up at her Son. "Darling, you've made me very happy. And judging from the amount of cum I feel leaking out of me right now, I'd say you've also made me pregnant. But we can't make love for the rest of our lives. As much as I loved having your wonderful cock inside me, it would be wrong for us to continue doing this."

"Then can we at least make love until morning?"

Cassidy felt her Son's cock twitch inside her. She leaned up and kissed his lips. "Yes Baby, you can make love to mommy until morning. You can even leave me tied up while you fuck me."

Mother and Son made love all night and into the following morning.

Mike came inside Cassidy five times over the next few hours.

As dawn began to peek through the bedroom window, Mike reluctantly untied his Mother.

They fell asleep in each other's arms just after sunrise.

As noon approached, they woke up, took a shower together, and got dressed.

As so often happens, guilt began to set in for Cassidy. She had cheated on her Husband with her Son. The distraught housewife didn't know how she'd face her Husband.

Shortly before 2pm, Cassidy and Mike were sitting on the couch, discussing what they'd done, when the doorbell rang.

Cassidy got up and answered the doorbell. She was shocked to see Eleanor Martin standing on the front porch with tears streaming down her face.

"Eleanor, what's wrong?"

"Can I please come in?"

"Of course, please come in." Cassidy led Eleanor to the couch, and made her comfortable.

Mike stood next to the couch and watched his lovers talk.

"Would you like something to drink?" Cassidy asked.

"A shot of bourbon would be good right about now."

Before Cassidy could respond, Eleanor said, "I know, I'm not supposed to drink while I'm pregnant. I'm just so confused."

Cassidy took the woman who was carrying her Grandchild by the arms and gazed into her eyes. "Do you want to talk about it?"

Eleanor nodded her head, and wiped away some of the tears. "I just found a letter on Robert's nightstand. It seems he's decided to come out of the closet. Cassidy, my Husband has left me for another man."

Cassidy felt a lump rise up in her throat. "Who did he leave you for?"

Eleanor wiped at her cheeks again. "Cassidy, you might want to check Arthur's nightstand."

Arthur and Robert were never seen again by their wives. They had moved part of their money to a bank in Bermuda. Handling their divorces through a local attorney, they gave their houses, cars, personal belongings, and the rest of their money to their wives.

Cassidy asked Eleanor to move in with Mike and her. She told Eleanor that she knew her baby was Mike's. Cassidy also told her friend what had happened between her Son and her.

Eleanor understood why her friend would do something so unthinkable. She also knew she would have to share Mike with his Mother. For some reason that Eleanor didn't fully understand, she decided that the arrangement would be a good one. She sold her house, and moved her personal belongings into Cassidy's home.

They weren't wealthy, but with the sale of Eleanor's home, they had enough money to live comfortably for several years.

That would give Mike plenty of time to finish his education and begin his career as a software designer.

Mike moved back home, and drove to his classes three days a week. The rest of his time was spent at home pleasing the two women in his life. He started addressing his Mother as Cassidy, except when they were in public or among friends.

Cassidy and Eleanor quickly discovered that they shared a secret desire to be with another woman. Soon they were making love to each other as often as they made love to Mike.

Cassidy would tie her pregnant lover to the bed, and lick Eleanor's pussy until she screamed.

The three of them shared the same king size bed, where they blissfully fucked each other silly every night.

One night while Mike was fucking Eleanor, as she was licking Cassidy's pussy; her water broke.

They untied the pregnant Mother and drove her to the hospital.

She had a baby girl and named her Trudy. Mike's name was written on the birth certificate as the Father.

Six weeks later, Cassidy used the home pregnancy test she'd bought the day before.

Mike was going to be a Father again.

Deciding that too many people knew them, Cassidy sold her home, and they moved across the country. They bought a big house in the suburbs.

When Cassidy's baby boy was born, Mike was listed as her Husband, and the Father of her child.

Eleanor had two children by Mike. She had Trudy, the oldest, and a boy three years later. Cassidy had three kids by her Son; two boys, and the youngest child, a girl named Cindy.

After graduating college, Mike went to work for a computer software company. Within five years he left the company and started his own software business. Three years later he made his first million. By the time his five kids were grown, Mike's computer software business had become a major corporation with more than two thousand employees.

As they grew up, the three boys got married, and moved to different states.

They would visit for Holidays, but mostly they stayed home to be with their own Families.

Trudy, the oldest, never showed any interest in men. Instead, she devoted her life to helping Daddy run the family business.

Cindy, the youngest; started college that same year. She majored in computers and technology. Like her half Sister, the pretty eighteen year old never showed any interest in boys. However, she did love her half sister, Trudy with all her heart.

But that is another story.
