It was a warm summer evening, and I was heading to my girlfriend's house for a sleepover. Lisa, my girlfriend, had planned a movie night with her family, and I was excited to spend some quality time with them. Little did I know that this particular evening would take a different turn.
As I approached the front door, I could hear laughter from inside. I knocked and was warmly greeted by Lisa's parents, who welcomed me into their home. Lisa, looking stunning as always, enveloped me in a hug, and I couldn't help but feel a surge of happiness. Her older sister, Sarah, was sitting on the couch, an enigmatic smile playing on her lips.
We all settled in for the movie, with Lisa snuggling up next to me and her parents on the adjacent couch. Sarah, however, sat on the other side of me, close enough that I could feel the heat radiating from her body. As the movie played, I couldn't help but feel a strange tension in the air.
During a particularly quiet scene, I felt Sarah's hand brush against mine. I assumed it was accidental and ignored it. But then, she did it again, this time more deliberately. I glanced at her, but she was fixated on the movie, that enigmatic smile still present. Confused, I tried to focus on the movie, but my mind kept racing with thoughts about what was happening.
As the evening progressed, Sarah's advances became more daring. She whispered compliments into my ear and grazed her fingers along my arm. I couldn't understand why she was doing this, especially with Lisa and her parents just a few feet away.
I excused myself to the bathroom, hoping for a moment of reprieve. As I washed my hands, I stared at myself in the mirror, trying to make sense of the situation. I knew I had to put an end to this, out of respect for Lisa and our relationship, even though Sarah's advances were turning me on.
When I returned to the living room, I sat down at a distance from Sarah, hoping that would send a clear message. However, she didn't seem deterred. Instead, she got up and joined me in the kitchen when I went to grab a drink. Alone and out of sight, she pressed herself against me, her intent unmistakable.
"Sarah, stop," I said firmly, trying to maintain control of the situation. "This isn't right. I love Lisa, and I won't do anything to hurt her."
She looked at me, disappointment flickering in her eyes, but then she smiled. "My sister doesn't have to know," she whispered, trying to convince me one last time.
Her temptation was effective and I let Sarah know that her advances were actually welcome. "Okay, Lisa is already asleep, so we can do whatever you want," I said, feeling my lust take over.
