Her husband had left her six month before. She would come on Mondays and Thursdays. The girls told her to bring her kids. Two more wouldn't make much ...difference as they had nine here already.When Cindy met Rita and saw what a good job she did, she hired her to clean her house on Wednesdays. Rita would leave her kids here then also. Cindy even found a lady she knew at work who hired Rita for Tuesday and Friday. We agreed to watch her kids then also.The girls had a regular child care center set. I lowered my driver's window to help clear the steamed-up glass and could hear Paul's deep grunts as he fucked Sam. This was no simulation. You just couldn't fake the sheer ecstasy that Sam was experiencing. "Oh fuck, Paul! Fuck me. Empty your balls inside me." I could hear every word through my open window. Not surprisingly my own cock was making it clear that it would like to join the party. "Cum inside me, Paul. I want you to shoot your spunk inside me!" Sam's words were erratic and. Never awkward between us, but I was growing up fast and it showed, my mood swings, my first periods, and my changing attitude towards men.Dad could see my changes, with my sullen attitude but most of all, my body ached and my unabashed sexual awakening. I was online shopping for clothes, with dad at my side, the tease in me reveled at his awkwardness as I choose my underwear, sometimes just to shock him, but I loved drawing attention to myself, with my choices, of skimpy tight panties and half. Won't you keep me company for the remainder of the trip?" he asked me.I couldn't say no. He was so sweet and his smile made me melt. I took a seat next to him and we began to talk. After an hour it was like I had known him my whole life. We laughed and smiled. He put his hand on my leg and we stopped talking. I looked at him. My heart fluttered, and then, he kissed me. Softly at first, then rough and passionate.It was dark and the bus was empty, so we began stripping each other. Insane passion.
