Mom pressed my swollen shaft against her pussy as she moved her hips up and down. I could feel her juices soaking my shaft as her pussy lips parted an... slid up and down her son's erect cock. As she slid up, she worked my huge swollen purple cock head against her aroused clit. Mom flicked my cock back and forth across her erect clit, causing her to roll her head back and moan in pleasure."Are you ready, Robbie?"

Let me cum!"Finally, I had pity on her - well not so much finally having pity on her as finally giving.
