Ace was a tall, muscular man with a huge cock, the kind of guy my little sister always went for. As he entered my room, I couldn't help but stare at his package outlined by his tight shorts. My sister, Chloe, followed him in, looking nervous. Ace had no idea that I had seen him change into a pair of boxers earlier that day, and I planned on taking full advantage of that knowledge.
Later that night, after Chloe went to bed, I snuck into Ace's room wearing only a shirt and shorts. My heart was racing as I climbed onto his bed and straddled his chest. "What are you doing?" he asked, startled. I didn't say anything; instead, I leaned in and gently bit his bottom lip. His hard cock pressed against me as he moaned softly.
