Let's see

Jerry moaned as Sam's lips wrapped around his cock and sucked him harder than she ever had before. This was a new kinkier side he had never seen from her before he bucked his hips a little as his cock seemed sealed within her lips, and she wasn't letting go.

"Holy shit........ FUCK!" He yelled before she finally released his member, looking up at him with a smile and licking her lips.

"Your cock tastes so good, Baby," she said before she stood up and began to slide off her shorts. "Now, wanna go upstairs?" She asked as she turned and headed towards the staircase, showing him her amazing-looking ass before ascending them, staring at him the whole time.

"Holy......" Jerry said as he stood up, kicking off his pants that were still wrapped around his ankles before he chased her up the stairs. When he arrived at the top, he stopped as the hallway was dark and Sam was nowhere to be seen. "Sam?" He said wondering where she had gone so quickly and quietly. "Honey?" He called out as he felt this chill up his spine.

Sam was different but he still couldn't quite figure out what it was. Despite the warnings going off in his brain, it was still his wife, and she looked sexy as Hell so he wasn't about to turn back now as he walked into the bedroom. She wasn't anywhere in sight, which confused him even more as he approached the bed.

"What the Hell?" He said before he heard the door slam shut behind him. "Holy shit! Sam, you......" he started to say,. Noticing this strange red reflection or glow in her eyes before, she pounced on him, pushing him down on the bed before she kissed him passionately.

"I knew you wouldn't make me wait too long," she said as he felt her body on top of his while she pulled his shirt off and kissed him again.

"Sam..... what...... what's gotten into you?" He asked between kisses, unable to deny the lust building inside them both.

"I just want to fuck you so bad," she said, acting like a wild animal as his cock was feeling her moist slit teasing him for a while before finally sliding inside.

"Shit!" Jerry blurted out, shocked by how good her pussy felt before she smiled and kissed him again, much slower, and began to move her hips just a little, driving him crazy. "Oh God, this feels so good."

"We should be doing this all the fucking time," she said, letting out a moan and biting her lip as she wrapped her arms around his head and held him close while moving her hips to milk his aching cock. "Oh fuck...... I forgot how good your cock feels. Fuck me every day, we need to do this every fucking day!" She demanded as her hips started to move faster.

"Sam......... fuck!" He said as his hands wrapped around his wife's ass and squeezed it as she moaned even louder. "Oh God........ this is the....... best......"

"Cum for my Jerry, fill my fucking pussy...... it's yours. I want to feel your cum inside me."

Jerry grabbed her by the waist and rolled her over, feeling a burst of energy he hadn't felt in years. He thrust his cock into her over and over again as she wrapped her legs around his waist and moaned even louder. She grabbed him and pulled him close, gently scraping her fingernails along his back as he continued to fuck her.

She felt her fangs start to sprout as the vampire inside her was starting to take over. She was conflicted as she wanted to bite him the moment he came, but she didn't want to hurt him either. Alex was young and full of life but Jerry was older, with a few minor health issues. Despite all of that though, she was moaning even louder as he pounded her pussy like a young man, not willing to let her down at all.

"Sam....... I'm gonna......" he said, trying to decide if he should pull out or not.

"Don't you fucking dare," she said as her eyes were now blood red and her fangs prominent for her husband to see.

He froze for just a moment, looking at the wild animal his wife had become, feeling shock and even a little fear, but he couldn't stop himself. He continued to thrust, feeling an arousal he had never felt before as his cock started to twitch and swell.

"Oh......... oh GOD!"

Jerry screamed as his cock started to blow inside his wife, much stronger than he expected. Sam let out a bloodthirsty scream herself before she pulled him down and sank her teeth into his shoulder, tasting his blood as her pussy filled with his cum. She couldn't help it, and even worried if he would question this later but for now, she wanted to take him and savor the moment, taking only a small amount of blood before removing her fangs and letting him collapse against her.

"Yes...... yes..... that was....... everything I wanted," she said as she licked Jerry's blood from her lips and held his limp body in her arms, feeling him still breathing and hearing his heartbeat. "Rest my love," she said, not letting him go.
