asked her to suck it!

Jack was becoming to aroused and had to do some thing. He walked over to his 17 year old sister who was masturbating with her panties down in front of him. "Suck it bitch!" he said violently. As expected she began this action without haste. her soft lips widened and a strand of saliva was the only thing between entrance to his sisters mouth. As the tip of his penis reached the edge of her tounge he gasped loudly.
"What?" She inquired.
"Nothing" he replied, "it just feels amazing to have my cock in your mouth! I've wanted this for so long!"

after about 2 minutes of slow sucking and revolving motions from Kelley's mouth, Jack could tell she was getting closer to a climax by the way her hips were bucking and she was groaning into his cock. Squeaking every now and then with pleasure.

Jack then retracted his cock and said "stand up." She did "Now go to mum as you are now, and say you've been a bad girl." For a moment Jack sensed a **** to this demand. But sure enough she complied wit the demand, waddling shamefully across the landing space towards the master bed room. Jack remained in Kelley's room, and a few seconds later he heard his mum scream,
"ahhhhh! Kelly pull your knickers up!" Jack then heard Kelly crying. Had she broken out of the trance? She came into her room tear stained, and as soon as she saw him she became furious.
"Get out of my room you dick!" Maybe she didn't know that it was him. He felt very guilty though. "This 'power' could mess up my family if I carry on like this."
