After a short ways the thought occurred to me that if she decided to come back right away she would run right into me and I thought it would be best t...o observe her for a time before actually trying to make contact.I crossed the river at another shallow area and climbed the hill on opposite side to the woods. I continued following the stream from just inside the woods until it came to a very large pool with a tall waterfall cascading down from a sheer cliff at the back.On the west side of the. I got the hand mirror and let mom have a look. She laughed and said she had never really seen her pussy before. She thought it looked real good. Then mom pointed out my boner that was causing a tent in my trunks. I was not even thinking about that and became embarrassed. Mom said that we were both very turned on.

He wanted her to enjoy this, and was rewarded with his administrations with her rocking her hips to and fro, also very slowly. He wasn't sure how long he could keep this up; he was still fully clothed and his hardened manhood simply YEARNED for freedom and attention.

Back and forth he went, bringing her to yet.
