Stop jerking off and touch her pussy?

I stopped jerking off but left my cock out for Rochelle to look at. I moved to sit closer to the edge of my seat and then I reached over and slid my hand along the inside of her right leg. She gasped a little and moved her hands away from her legs. I thought maybe she was going to stop me, but instead, she leaned back a little further in her chair and opened her legs a little wider for me.

I slid my hand up her soft legs to her panties and began to rub her pussy lightly over them. She bit her lip and closed her eyes as I touched her. She opened them again though and looked past me to the opening, before looking back at me. I slid my fingers under the edge of her panties and underneath. I felt her pussy hair and then felt her warm, wet slit! I slid my hand up and down her slit and her breathing got a little heavier. I found her clit and began to rub her there...

"Mom?"

Rochelle and I jumped. Rochelle quickly pulled her t-shirt down and I quickly sat back in my seat and tucked my cock away as Diane came into the room from the kitchen.

"Yes?" Rochelle asked, picking up her coffee mug with trembling hands.

"We're going to go into town with Robin for lunch today," Diane said.

"OK, honey," Rochelle answered. "That's fine."

Diane left the room and we could hear her and Jenny heading to their room to get ready. I could also hear Tim in the kitchen now, and I knew Rochelle and I were not going to be able to continue. Fuck! Rochelle smiled at me and brought her coffee mug into the kitchen. I waited in the other room for my hard on to die down which pretty much took until Tim was done his breakfast.

Tim and I spent the day swimming and fishing from the dock. We had lunch with Rochelle, and the girls returned for supper. We all spent the evening sitting on the deck, chatting. All day and night, I tried to be alone with Rochelle, but we never got the chance. She would look at me and smile, and I would stare at her. Damn, I wanted her so badly!

That night I jacked off in the bathroom thinking about how she teased me that day. There was no way I would have been able to sleep if I hadn't masturbated. I was tired from getting up early too, and slept in fairly late.

It was the last day of the trip. We were going to leave bright an early the next morning. It had been a fucking awesome trip but I would be very sad if Rochelle and I didn't get another chance to be alone.

We all had breakfast together and Tim and I spent the morning swimming. It was very hot and humid out. Rochelle was wearing her awesome blue bikini, and the rest of us kept our bathing suits on. Rochelle barbequed hotdogs for us again. We all sat down to eat; Rochelle sat across from me and ate with us. As we sat there, I suddenly felt a foot on my crotch. I jumped a little, but no one seemed to notice. I looked across the table and Diane was looking at me. For a crazy second, I thought it was her foot, but then she looked away and Rochelle was looking at me with a tiny smirk on her face. I could feel my cock getting hard as her foot caressed it over my bathing suit.
