Jerk off with my free hand?

This was too fucking hot and I couldn't help myself. As I kneaded her big tit, my free hand reached underneath the leg of my boxers and pulled my hard cock out. Rochelle gasped as she saw what I was doing and stared at my hard cock in my hand. I started to jerk off while I touched her.

"We should stop," she whispered as she watched me stroking my cock, but her left hand reached over and started to rub my leg up and down above my knee. She got closer and closer to my cock, so I stopped jerking and moved my hand away on one of her upswings. She took my cock into her hand, and I almost exploded right away. She began to very slowly slide her hand up and down my shaft. Rochelle was stroking my cock!

"Mom?"

Rochelle and I jumped. Rochelle quickly pulled her t-shirt down and I quickly tucked my cock back into my boxers 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. As she walked out of the room, she teasingly lifted her t-shirt up, flashing her panties and ass at me. She turned to smiled at me as she disappeared around the corner. 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.
