Yes

“S..s..sure”, I replied.
I realised immediately that I was excited about talking to the woman who had seen my cock. I was also worried if they might joke about it.
I locked my caravan door and walked over their van.
I decided some conversation was necessary.
“When did you arrive?”
“About 11 this morning. By the way my name is Brenda, and this is Joy”, said the bigger woman.
“Dave”, I said in reply.
Joy nodded. She was slim, and I liked slim woman. However I had never had any sort of sexual relationship with a woman of her age. I felt blood moving rapidly into my cock. “Down boy”, I thought, “It is very unlikely that anything will be happening.”
“What would you like to drink?” asked Brenda.
“Do you have a beer?” I replied.
“Yes. Now while I pop into the caravan perhaps you can put some after sun on Joy.
Her shoulders are far too red. It’s her fault. All she has done since we arrived is sunbath”.
“OK”, I said. My cock started to harden again.
My thoughts were working overtime. It was like having a saint and the devil in my brain, talking to me in turns.
“It’s only her shoulders. Yes, but to be touching her skin and shoulders can be quite sexy. Brenda will stop anything happening. If I stand behind her and she is sitting down when I rub her shoulders how much of her little tits will I be able to see? You shouldn’t be thinking like that. Joy saw my cock. She must have told Brenda. Perhaps they want a threesome. At 60! They will have had bigger ones that yours”.
“After sun”.
Brenda’s voice brought me out of my thoughts with a start.
“I’ll sit in this chair, if that’s OK”, said Joy in a very quiet voice.
“Fine”. I tried to sound nonchalant.
"I'll go and get the drinks", said Brenda.
Joy sat down and undid three buttons on her blouse. She then opened it wider so that her shoulders were visible. The thought did cross my mind that considering she had only just met me it was a little unusual to allow me to do this. The other thought was about trying to look further down her blouse.
I stood behind her and carefully squirted some cream on her left shoulder.
A soft “Oh” of surprise left Joys’ lips. I started to rub it in and tried to glance down her front. There wasn’t much of a cleavage and the blouse was not see through. I realised though she was not wearing a bra. No straps. I put some cream on her right shoulder. Too much actually. I started to rub it into her skin a little below the top of her shoulder and towards her neck. How low should I go? Joy had been a little tense at first but how seemed more relaxed.
Suddenly she said “That’s nice”.
Was that a come on? Where was Brenda? Should I go lower? Had Brenda disappeared on purpose? It was decision time. Do I put my hands inside her blouse or not.
