I laid back in the chair with my panties on remembering a night about 30 years ago. Wow was my body sore the next day. My hand slid under the lace and silk panty I was wearing and felt my cock start to stir. I found myself in the middle of a threesome, between a wife and her husband. I was unconciously stroking as I thought back. I was fucking his wife and I felt his tongue in my ass, God did it feel great. A little pre cum was showing through the blue satin. Then he mounted me while I was still in his wife and shoved his throbbing cock in me. I was in ecstasy. My load shot through the lacy panties as I remembered the three of us on that special night.
