Selecting a satellite service she slid into a waiting chair and searched briefly for the porn channels. Soon a pretty young thing was attacking a huge...throbbing dick. Stephanie wouldn't be caught dead sucking on a man's cock but there was something appealing in this when the cocksucker was a gorgeous naked woman. The girl worked the shaft expertly Stephanie mentally took notes. Someday she would have a girlfriend who would do that for her and she wanted to know what to ask for. Strictly. "Did you hear that?" Daddy asked. "You have possibility." Thank you Daddy" I replied, with a smile. "I always want to please you but I didn't know that you'd be bringing another" You're on a 'Need to Know' basis, young lady" replied Daddy. "And based on your performance today, or lack thereof, you might be seeing Her again. By the way, should you see Her again, you will address Her a Mistress. Do you understand?" Yes Daddy" I replied. "But you do realize that I could NEVER commit to three days. I never thought of doing anything wrong, of course.I’m not that kind of a guy.So after they left, I randomly went up and rang the bell. Priti opened the door and welcomed me in. I was happy. Not because we both were alone. But because I thought I could have a break today.She was still working on some math problems that her mother had given her the past day. I’m good at math. So I just helped her here and there and she finished her work.We weren’t that friendly. It was just some his and hellos.. Fuck me Daddy...” she cried out as, the old guy was hitting home deep into her. I could hear her juices squishing as his cock went into her; I could hear their hips slapping together as they now rhythmically fucked each other.He slowed down his thrusting into her and she pushed her fingers down into the sand. He groaned, “I’m going to cum.”She rocked her hips faster and encouraged him, “Fuck me .... cum in me Daddy, fill my pussy Daddy ....”, she went on.He gave one last really hard thrust into.
