Mom’s eyes had been glazed over most of the day since she had came into the house. “Yes, I’m amazed how interesting your body looks,... I just can‘t stop staring” She then got closer to me and we kissed passionately for the first time. I kissed her back, sticking my tongue in her mouth, moving it around in circles. She leant me back into the water, my back set against the shower wall. She started to pinch my nipples on my breasts. I started to moan softly, that felt so good!.

He was husky enough and, not having shaved since we arrived,. Stopping when my lips caressed my mother's exposed clit. "Tell me about it Mother. Don't leave any details out."My Mom spread her legs even farther apart inviting me to lick her some more.

Then she told me she was on her period and didn't want to fuck in my truck because she didn't want to make a mess. My heart was broken and my balls were throbbing!! Then she looked me in the eyes and said she wanted to do something different.She started licking the tip of my rock hard cock and she said play with my ass!! Like I was going to say no lol!! I started.
