My younger brother's girlfriend is a sex-loving woman who likes to be cuckolded and gets excited on her own. My younger brother is out, so I'm alone with his girlfriend. We were having a normal conversation, but suddenly the room became silent... We both suddenly became aware of each other, and she became nervous and fidgety. I could see her panties through the gap in her miniskirt... her wet lips... I was tempted by her sexy thighs...
