I watched with satisfaction as he drained the shake, the effects of the medicine starting to take hold.

"Wait, I'm getting dizzy," Matthew groaned, clutching his head. He swayed, about to fall, and I caught him, guiding him towards the bedroom.

"It's alright, Matthew. You'll be fine," I said, though my heart hammered in my chest.

Once inside, I began my mission. I sat on top of him, my fingers working to undo his buttons.

"Kourtney, what are you doing?" His voice was weak.

"Matthew, I want to make love with you," I whispered, my breath hot against his ear.

"No, Kourtney. This is wrong," he protested, trying to push me away. But I silenced him with a kiss, claiming his lips.

I held him, kissing him deeply, until I felt his response, a tremor of desire running through him.

Suddenly, I was naked, Matthew on top of me, his hips thrusting against mine. I felt his length inside me, a sharp, tearing sensation. A delicious pain, a primal ache that made me moan and grip the sheets.

"Faster!" I cried out, my voice ragged with need.

Then, a wave of heat exploded inside me, lifting me to a dizzying peak. I squeezed my eyes shut, savoring the moment, a memory forever etched in my mind.

"I love you, Lorelei," he whispered, his voice thick with emotion. I stared at him, my heart sinking.

I thought in this moment, in this shared intimacy, he would forget Lorelei. But her name still clung to his lips, a constant reminder of her presence in his heart.

"Kourtney, what happened last night?" Matthew asked. He couldn't remember the night before, and the missed anniversary date weighed heavily on him.

I lowered my gaze, pretending ignorance. "I-I don't know. I just found myself beside you."

Matthew's eyes widened, a flicker of realization crossing his face. "No way! Tell me nothing happened between us last night?" His voice was sharp, tinged with anger.

"I'm not sure, but I think we did it," I said, biting my lip, trying to appear innocent.

Matthew jumped out of bed, scrambling to get dressed. "This is crazy! We can't do this, Kourtney. You know I'm married, and I love your sister so much!"

"I know, but she doesn't love you the way I do. Matthew, why don't you just divorce her? Marry me instead. I can give you everything you want," I pleaded.

"Shut up! You're out of your mind. Lorelei would never forgive me if she found out. " Matthew snapped, turning to leave. But I stopped him.
