Through a used panties trading social network, I met a beautiful older woman who gifted me the panties she had worn all day. Inspired, I had her put them back on and make them even dirtier. Using a vibrator and electric massager to tease and torment her, I was surprised by how responsive she became, making it impossible not to fully enjoy myself. Even when I couldn't hold back and pulled out my cock, she gladly accepted it. In the end, I reached climax through a panties-mounted cowgirl position and a handjob done through the panties.
