Thunder

Karen began to shake with anticipation. She had no idea if she could take his entire length, but the thought of it made her feel giddy.

Benny slowly withdrew his cock until only the head was still inside his aunt's body.

Karen felt her stretched out pussy being emptied inch by inch. "Please be gentle." Her voice could barely be heard.

Thunder struck, rocking the entire house.

Karen clamped her legs down onto his hips again, ramming her nephew's monster back inside her.

"Oh fuck," she screamed in pain, and passion as the tip of his helmet slammed against the entrance to her womb.

Benny stopped and gazed into his aunt's eyes. "Did I hurt you?"

Her eyes burned with lust and fear. "Don't stop. Fuck me hard."

Benny withdrew his cock again and slammed back into her.

Karen bit her lower lip as the helmet of his manhood slammed against the bottom of her depths. She clamped her legs tightly around his hips. The fear she felt was quickly replaced with other feelings. She became dizzy with confusion, pain, and lust. Her body screamed for more. Karen wanted Benny to pound the bottom out of her womb. She wanted him to saw her in half lengthwise with his wonderful weapon.

Benny rammed into her again and again. His cock was like a pile driver, trying to break through her cervix and enter her womb.

Karen clung to her nephew, and begged him to fuck her harder. All thoughts of right and wrong left her mind.

The storm no longer terrified her.

She wanted this. She needed it. She wanted her nephew to pound her right through the mattress and box springs.

Benny felt his cock swelling with each thrust. He also felt her vaginal canal opening more and more. He was almost completely inside her. Just one more inch and their pelvises would meet. He drew back and rammed his monster home.

Karen shrieked as her body accepted the last of his huge dick. "I've got all of you," she screamed. "I can feel all of you inside me. You're so deep. Oh, fuck me baby. Fuck your dirty aunt until she can't take it any more."

Benny pounded Karen over and over. His huge cock stretched her like she'd never been stretched before.

Karen's mind was reeling with lust. She'd never been used like this in her entire life. Yes, it was her Sister's son pounding her out, but it was also the best sex she'd ever had.

Benny rammed into his aunt over and over. His dick continued to swell inside her with each inward thrust. His balls began to beg for release.

The couple continued to thrust against one another, grunting, and moaning with lust. Their bodies were saturated with sweat, and they smelled of sex.

Aunt and nephew weren't making love. They were fucking. They were rutting like animals consumed with lust. Neither of them noticed that the thunder had stopped shaking the house.

Karen felt her orgasm building. "Harder," she screamed. "Fuck me harder."

Benny rammed his swollen cock into her body like a piston rod. He growled like an angry dog.

Karen's eyes flew wide as her orgasm ripped through her writhing body. She began to tremble uncontrollably. She whined, moaned, and screamed into the night as her loins threatened to come apart.

Benny felt his balls tightening. He thrust as hard and deep into her as he could. "Oh shit," he shouted as his body began to release his sperm into her womb.

They writhed, and shook together, their lust exploding together. Aunt and nephew clung together as their bodies shook one final time.

Benny collapsed onto his aunt in exhaustion.

Karen clung to her nephew, her arms and legs still wrapped tightly around him. She kissed the side of his neck. "Baby, I needed that so badly."

"I've wanted to make love to you for as long as I can remember."

Taking hold of his face, she looked directly into his eyes. She gave him a loving smile. "You know that what we did was wrong. If people ever found out about this it would ruin our lives."

He returned her smile. "No one will ever find out. I'll carry our secret to the grave."

"Still, we shouldn't have done this. It was wrong."

Benny stroked his aunt's face. "Do you regret what we did?"

A tear welled up in the corner of Karen's left eye. She leaned up and kissed her nephew. "No, I don't regret it. What we did was wrong, but it was also wonderful. I know this shouldn't happen again, but I need you. I need you in my bed. And I need you in my life."

"You will have me for as long as you want me."

A sudden thought ran through her mind. The reason she'd never had a child was because her late husband was sterile.

Benny on the other hand was most likely a very fertile young man. And at that moment millions of his sperm were swimming around inside her body, hunting for an egg to fertilize.

Karen did a quick calculation in her head. She was indeed at the peak time of fertility. Yet for some strange reason the thought that her nephew might end up making her pregnant didn't frighten Karen at all. If anything it made her want him even more.

Thunder rumbled in the distance as the lovers lay together.

Karen trembled at the distant sound. She reached up and caressed Benny's face. "Another storm is coming in. You might need to help me keep my mind off of it."

His Aunt's invitation caused the young man's cock to twitch inside her.

Karen gasped in delight as she felt his cock begin to harden, and stretch her again. "Something tells me that I'm not going to get much sleep tonight. And I don't think the thunder will be the reason."
