Suddenly his hand moved down to her groin and cupped her vagina in his large hand. His middle finger slid inside her and her body involuntarily presse... down to meet it. 'Oh...yes' she gulped and Rob built up a steady rhythm sliding his finger in and out. His thumb moved up to her clitoris and massaged her swollen bead. He felt her tight muscle contract on his finger and knew she was close. He purposely slowed his rhythm and removed his thumb and finger. He drew his hand up to her mouth and she. Josh said, ‘Mister if you try to run, we’ll catch you and tie you face down across your saddle. Either way, sitting up or face down, you’re coming with us back to the ranch. It’s your choice how you get there.’ Josh and Red started the cattle back toward home and the man rode at the back of the small herd with Josh. Red rode point and helped keep the cattle headed in the right direction as Josh drove them from behind. It took the better part of the day to get the animals back near the ranch. My wife left the tub, claiming she was tired. Telling us to "Not stay up too late," we agreed.A few minutes later, my step-daughter climbed out, smirking, saying "Don't do anything I wouldn't do," before heading down the hall and closing her bedroom door.The conversation Katie and I had turned out to be quite graphic, sexually depict, and interesting to say the least.We wound up against the hot tub wall kissing passionately. She had her large breasts pushed up against my bare chest. I had to. I was really shocked and was sweating as she was sitting very close to me. It was really hard to control my erection. She started talking casually and asked my whereabouts and she also told me about her work, her k**s. She is currently single and recently got separated from her partner. I started to feel comfortable with her as she was very friendly. She then asked me if I am not going naked like all others. I said this is my first time at a nudist beach and I have never been nude in front of.
