The neighbor's mom, who moved in recently, is my mom's friend and came over for a drinking party. I was made to sit next to her, and her cleavage and panty flash kept catching my eye. When she was taking a bath, I couldn't help but smell the lingerie she was wearing earlier. As I was doing so, she opened the bathroom door and purposely showed me her naked body. Unable to hold back any longer, I got drunk and fell asleep next to my mom. I took advantage of the situation and made the older woman hold my cock, demanding she take responsibility. She said, "I'll teach you how an adult takes responsibility, so don't run away," and then proceeded to give me a thorough lesson on her incredibly sexy adult body. My own urges couldn't be contained, and I relentlessly teased and drove the sweaty older woman to multiple orgasms. In the process, I felt like I was finally growing up too.
