Her torso was trim and defined. As the top edge of her bikini began to clear the surface she still showed no signs of masculinity.At this moment I did... not know what to expect. My anticipation was thick as catchup. I found myself totally focused on the surface of the water where it met the cloth of her bikini bottoms. I watched intently as she continued to rise. At about the time the final third of her bikini was beginning to show I detected the telltale bulge."Oh my god," I thought to. . is ... what it's like to have ... two ... dicks in your p ... ppussy at once? I want to try that next ... after I recohhh ... uhh..." In seconds she came again and gushed on the fingers and finger food within her.

They offered her a taste, but she still struggled with breathing and finally stuttered, "I have one of my own coming soon."The next young girl lay down, pulled back and spread her legs. I got up and walked a few steps over to String Bikini lady. I took my towel to kneel on, because I didn't want to impose and sit on her blanket."Hi, I'm Jim. I saw you here yesterday and thought I'd say hello."My sisters were laughing and staring but trying not to show it.String Bikini lady lifted up her sunglasses and smiled at me. "Well hi Jim, pleased to meet you, I'm Jill." My sisters were surprised.Jill whispered so my sisters couldn't hear. "I heard the bet with your sisters. Let's make. After a few minutes of nice, slow balling, we both seemed to make our way toward an orgasm. Katie began fucking me more quickly – legs locked tight around me and breathing hard. I was panting and sweating with the effort – what a great workout! When she pulled away a little to look into my eyes once again, she smiled and I knew she was ready to cum. Katie liked to look at me as we came and this would be no different. As she stared into my eyes, and I into hers, she laughed a little as we kept.
