Memories of the years-long affair raced through Samuel's head as he pulled up in front of his son, Liam, and his wife, Hanna, built north of Bozeman, Montana. Liam is an avid hunter who has a large following on social media for his hunting channel, which means that Liam was away most of the time.

The affair started simply enough. Hanna was five months pregnant and didn't want to be alone in their new house while Liam was away filming. With her parents back in New Jersey, it was up to Sam to step in. He was happy to do it. Ever since the loss of his wife, Ester, a few years ago, he has wanted to be around anytime his son needed him.

Today, Liam rushed to load his gear. He was late and needed to make up time, because there'd be no way of finding their camp after dark. Liam kissed Hanna goodbye and reminded her again that the Co-op would be making a delivery the next day. It was his third time that he reminded her. "I'll assemble it when I get back," Liam told her, knowing full well that his father loved projects and would have it assembled before he got back. "Thanks again for coming, Dad. Hanna feels a lot safer having you over." Liam jumped in his truck and sped off.

The next morning, while he and Hanna ate breakfast, the delivery truck rumbled up at the end of their driveway. Sam watched out the window as Hanna showed the driver where to put the pallet. He could see that the conversation was not going well and went to join them. The delivery driver was arguing that the ground was too wet and there was no way for him to take the pallet to the back side of the house. Sam, ever the peacemaker, told the driver to get it up the driver as far as possible, and he would move it the rest of the way by hand. By ten thirty, he had everything moved next to the cement slab that Liam had poured for Hanna's she shed.

Hanna stopped dead in her tracks when she came out to bring him something to drink. She watched as Pop, as she called him, wiped his face with his shirt. Beads of sweat gleamed in the sunlight as they trickled down his chest. His muscular, chiseled physique reminded her of her husband when they had first met. She couldn't take her eyes off Samuel's shimmering, sweat-covered body.

Pregnancy causes odd cravings. Some crave pickles and ice cream, while others crave something savory and sweet. Still, others, like Hanna, with their raging hormones, crave something sexual. Seeing her father-in-law's greying blonde hair glowing in the sun. His icy blue eyes and rippling muscles sent a familiar tingle through her nethers. She couldn't contain her arousal, and she pretended to read the instructions while she ogled Sam. Her offer to help him was only an excuse to be near him. To watch him. To lust after him. The hours passed quickly, and by the end, her panties were a sloppy mess from the steady trickle of her aroused state.

Hanna hugged him, inwardly longing to be in his arms. Their sweaty embrace seemed uncomfortably long as she contemplated how she could seduce him.

"I'm sorry, hun. I'm covered in sweat and must smell awful." Sam apologized.

Hanna said she was so appreciative that she didn't care, giving him a peck on the cheek and thanking him for erecting her shed. In her heated state, Hanna envisioned something else erecting. An idea began to percolate in her mind as she watched Sam head inside for a shower.

She followed him inside, removing her blouse and bra. She then stood outside the bathroom door, waiting to hear the shower turn off. She stepped toward the door, just as Sam stepped out wearing only a towel around his waist. They collided, bumping bare-chested into each other while she acted as if she were putting on her shirt. Hanna muttered an apology. "I'm sorry, Pop. I couldn't take wearing that bra another second. I can't believe how big they've gotten."

Hanna had the hornies that she needed scratched, and she was determined to have Pop scratch it. A convincing tear trickled down her cheek as she said, "I wish Liam weren't so busy. I know he's providing for his family, but he's neglecting some things around here." Pop reached for her to comfort her.

Hanna laid her head on Sam's broad shoulder, collapsing into his arms, pressing her breasts against his bare chest. Her hands fell, brushing across his burgeoning penis. "Fucking hormones got me so horny, Pop, that I don't know what to do. And he's never around." Hanna tugged his towel off and led him, naked, to the couch, where she knelt between his knees.

"Ester had the hormone hornies when she was carrying Liam. I got laid on the daily—the best nine months of my life. She couldn't get enough of me. We got up to three or four times a day at one point, so I understand that you have needs," he said as Hanna's lips closed around the head of his cock. "Go ahead, hun. Do what you need to do." Hanna, feeding her lust, wrapped her lips around the head of her now erect cock. She licked along his vein as she took him in and out of her mouth. Sam wanted to let her suck his cock for as long as she wanted, but knew she had far greater needs lurking deep inside.

"Do you want to come up here?" Sam patted his lap. Hanna stood, hooking her thumbs into the waistband of her pants and underwear, and slid them off before climbing onto Pop's lap. He kissed her, invading her mouth with his tongue. Hanna kissed back with hunger and passion. She brought his strong hands to her breasts, squeezing them to her tits. The touch of his hands made her twat tingle. She grabbed his cock, pressing it against her while she ground her wet pussy on his steely rod.

A rush of pleasure swept through her, fanning the fire of her desire. She pulled his face to her bosom, begging for him to suck her tits. Every suck of his mouth. Every twitch of his tongue tantalized Hanna's twat, tickling her to orgasm, driving her to break her vows.

A gush of colostrum coated Samuel's tongue. He lifted his head, kissing Hanna, Frenching the sweet, salty fluid into her mouth. She pulled his mouth back to her breast, gasping, "Oh god," as he latched on to her nipple. "Suck my tits, Pop. Suck um hard." Hanna tilted her hips, burying Pop's cock into her vagina with her next downward thrust. She rocked and twisted her hips as she rode his cock. "Ahh, god, Pop. I'm cummmmming," she whimpered.

"Cum for me, Hanna. Cum on my cock. Cum, honey," Samuel gasped as he drove his hips upward, meeting Hanna's thrusts. Sam again raised his lips to share her savory fluid while they feverishly kissed. She bit his bottom lip as she raked her fingernails across his back, leaving long red welts across his flesh.

Hanna yearned for more of his cock, but her belly bump prevented it. She tossed the throw pillow off the arm of the couch before changing positions. Looking back over her shoulder, "Deeper, Pop," she said, bracing herself to be railed by her father-in-law.

Eager to please, Sam lined up behind her, driving his cock into her wanton hole, making her groan as he bottomed out in her vagina. "Fuck me, Pop. Fuck me hard!" Hanna groaned as he impaled her on his cock. His long, deep thrusts battered spots long neglected by his son. "I'm cumming, Pop! I'm cumming. I'm cummmming! Ahhh, fffuck me, Pop," she squealed.

Sam could feel her vagina quivering like a vibrator on rock crusher mode, spasming on his cock. "I'm gonna cum, too, honey. I'm cumming." Sam continued to pound his fuck stick into her, tainting his son's bride. Their bodies convulsed as one being as they climaxed in unison.

The lurid memory of the start of their affair faded as Hanna came out of the house carrying the newest addition to the family. "Hey, Pop. I want you to meet Samuel."

"Samuel?"

"Yes. After finding out that it was a boy, I told Liam that I wanted to name him after you because you've been such a big part of our lives."

The child's icy, blue eyes blinked open as Samuel cautiously cradled the boy.

"Is it?"

"Uh, huh. The timing lines up with your last visit." Hanna said in a soft, hushed tone.

They exchanged a knowing look, conveying their desire to be alone and perhaps add to their family.
