"Please Sammy, fuck me faster and harder."I slowly started picking up speed as I slowly fucked her pussy with my rock hard cock.When I got to fucking ...oanne's pussy as fast and hard as I could, it just took a few strokes when I felt that she was about ready to cum and I could feel my balls start to let my cum out."I'm about to cum Sammy! I need to cum Sammy, fuck make me cum."Just as she said the word 'cum' the last time, I let my cum go in as deep as I could get my rock hard cock into Joanne's. As shedid, she was stooping low and was next to my groin and that's when shenoticed it. My cock cage outlined in the thong panty I wore.Rhonda looked up at me and asked, "Danni? Is this what the key isfor?" I could tell she was a bit incredulous to make this discovery.I nodded, embarrassed that my sister now knew. And understood. Thatfor the past three weeks Grace has had my penis under lock and key.And my own sister held the key to my freedom."Oh Danni!" she exclaimed. "I am so sorry. . I was about to walk out the door when Mother suggested I bring mydancewear. "What do I need dancewear for if I'm just babysitting,Mother?" I could tell Mother was upset by my questioning her authorityand I quickly started up the stairs to gather my leotard, some tights,and my ballet slippers. I was smart enough to grab a sports panty and asports bra and stuffed those into my bag as well. I've been to enoughexercise classes to know what I need to bring. I keep a makeup bag readyas well with. Her caution managed to push through the thick fog of lust. Perhaps, it would be wiser to leave... see if the others could find room for her. She turned towards the door and didn't see when Mark stepped silently out of the bathroom. Before she could reach the door a strong hand closed over her mouth and another wrapped around her waist. Mark pulled her back against the firm muscles of his body and the even firmer, insistent pressure of his dick against her lower back. She tried to say something.
