When I started back, I said to Kim, “Hey, there’s a State Park right here, why don’t I just pull in and we can finish up?” She agreed and I pa...ked in a lovely grove of trees in the shade. As I parked, Kim was reluctantly getting out of the passenger seat, and said to me, “That was a great Birthday lunch. Thank you.”“Today is your birthday?”, I stated.“Yes, but you’re the only one who knows.” She informed me.“Well,” I said, as I got to my feet from behind the wheel, sidled up to her, face to. "If this is to work out you'll need to answer my questions and listen to my terms. Do you understand?" She waited a long minute and continued. "Do you understand, Charles?" "Yes, Ma'am." "Good. Gerhard and I have certain rules which allow us a great deal of sexual freedom while keeping our marriage intact. You will need to obey our rules if you're to fuck me. Will you?" "Yes, Ma'am." "Come sit with me on the sofa. Gerhard will sit with Elaine. There, that is nice. Are you hard, Charles?" "Yes,. Everyone started to laugh, especially when she slipped and fall right in up to her neck squealing before jumping back up her body now soaked and glistening, Tom's mouth was struggling to stay shut as he saw her firm tits pop out of her top he laughed before jumping under the water and popping up next to everyone. For the rest of the day everyone swam around making up odd on the spot games, until around 5:00pm some had left leaving just Debbie who by now had gotten used to feeling the cold water. He finger fucked my ass hard and deep, I couldn't focus on sucking him as I became overwhelmed with ecstasy. When I would stop, he would spank me hard and say, "Keep sucking!!!" Somehow, the spankings encouraged me and cleared my head and I was able to resume sucking him with vigor. I could tell that he wanted to stick his cock in my pussy and I said, "I'm on my period." He said, "I know." He came to the back side of me and plunged himself deep into my pussy. He didn't even remove the tampon,.
