She said hi and then we stood and looked at each other for a long time. We sat on the ground and she let her skirt fall part way down her thighs. She... began putting her hands on her breasts. My penis stiffened. I watched her roll her hard nipples between he fingers. I rubbed my jeans feeling the stiff cock under the fabric. Before long she lifted her top up over her pale breasts. Her nipples were large with a big nib in the middle of pale pink areoles. She continued to play with her nipples. The young museum employee with very effeminate mannerisms and wearing very tight pants with a nice package showing informed them that the museum was closing. He stood with his hand on his hip advertising his package as he smiled and looked at them. He was thinking of how nice they looked. The employee knew the gentleman and his tastes for young chubby guys as they had shared a coffee one time at the museum's café. The employee liked mature gentlemen but those who were sub and Richard did not. "Just in time, my dear. Our guest is about to leave, although I have urged him to stay longer. Perhaps you can add your persuasion to mine and change his mind." "I am sorry," I said. "I must go. Allow me to thank you most sincerely for your hospitality." Samantha came forward to shake my hand. "I am most happy to have met you, sir," she said, her voice as soft and pleasant as ever. "Thank you for visiting us." "It was--" I said, and checked myself. I had started to say it. The intensity of Rebecca's pounding took away my restraint, and I found it necessary to fight to stave off cumming as long as possible.As Rebecca climbed towards her peak, I felt her vagina squeeze me rhythmically, killing my control and forcing spurt after spurt of semen inside her hungry body. My climax seemed to trigger hers, and she cried, screamed, and beat her fists against my chest, as she came and came. Colleen wrapped her arms around Rebecca's naked body, squeezing her nipples with one.
