"We will have to work on your cock sucking skills, young man...” She chided. I became terrified and excited all at the same time, as she inferred we...would have another encounter. She brought a hand up to her mouth and licked her palm, before returning it to her hard cock and slowly stroked it. "Kneel between my legs. I want you to lick my balls", was her command and I obeyed. She opened her legs enough for me to slide between them and suckle and lick at her large, soft balls. Her musky scent. Maybe I can cool him off." I don't know what it is. I only know his home phone number." Give me that, then."I rang the number CeeCee supplied me with. "Mrs. Cooper, this is Dick Trouper. You know, CeeCee's husband. I need to talk to Matt. Could you give me his cell number?" Yes, of course. Is CeeCee sick?" No, she is at her mother's. She called me and wants to relay a message to Matt. She doesn't have either his cell number or this number at home so she asked me to call, rather than go through. He tried to push me away, but I could not be denied. I lay between his legs, is balls just an inch from my chin and both hands on his penis. I squeezed one more and a little drop appeared. He wiped it from the head and held the finger out to me. I licked it and then bit the finger keeping it in my teeth. With it in my teeth I got up on all fours and crawled up to his mouth. I dropped the finger from my mouth and pushed my mouth over his and had a long tonguing kiss. Then we both fell back into. Then she tried to hide it but i somehow manage to open the laptop. I saw that her best friend and her boyfriend where having sex. I asked what was it and she replied that her friend forced her to see this. Then i told her not to do this kind of activities when mom is around.I then went to my room and freshen up myself and was thinking about what i saw and my tool became erect. At that time i was thinking badly about my sister. I thought of seducing her. I went to her room with t-shirt & shorts.
