Suggest going for a walk?

I asked her if she wanted to go for a walk around the mouth of the river and over to the other side. She hesitated for a bit as she knew it was muddy, but didn't complain. I watched her remove her shoes and socks, yet still tried not to make it obvious. As soon as both socks came off her toes started wiggling and before long I had a noticeable erection. She also had a coat of black nail polish on which didn't make the bulge any smaller. We started walking towards the bank of the inlet, it began as sand but soon turned to soft 2 inch deep mud. I watched in amazement as Aliesha's feet squelched through the muddy ooze, the soft mud covering her toes hiding her nail polish. She seemed to enjoy the feeling in between her toes. As soon as we steeped into the water the mud cleared of our feet revealing her black toes. All I could do was imagine about sucking on them for hours and hours." Are you staring at my feet" she said with a kinky looking smile. I look at her with a guilty face. "Uhh no I wasn't" I lied. " We both know you were, do you like feet?" She asked.
