In the first installment, Jimmy Jefferson, after a sexually frustrating date, rushed home to beat off. He neglected to close the door that led to the bathroom that he shared with his little sister, Jill, resulting her accidentally watching as he masturbated. The last sentence of the episode was, "Then she looked at her brother's face and saw that he was looking directly at her." *
Jill quickly ducked back into the bathroom. Had he seen her? She listened carefully. Nothing. Wouldn't he have immediately gotten up, or at least have called out to her? She had been stifling the urge to pee, which was why she got up in the first place, so she very carefully closed and locked the door to his room.
Jimmy was quite sure that he had never had an orgasm that powerful nor ejaculated that much in his life. He enjoyed watching the huge wads of his own sperm as they jetted from his enormous cock and landed on the headboard, in his hair, and on his body. He couldn't imagine that it could feel better to actually fuck a girl than this.
Just then, out of the corner of his eye, he saw the bathroom door being pulled to and heard the almost inaudible click of the lock. Shit! In his haste, he had forgotten to even close the door to the bathroom. What if Jill had seen? Wait. While he was cumming he had, subconsciously, thought for a brief second that someone (Jill?) was peering out from the bathroom, but the intense pleasure had blocked everything out. A marching band could have entered the room and he would have been unable, at that point, to have stopped himself from completing what his body so desperately demanded.
But now that he could think rationally, was it possible that she -- and of course it would have been Jill -- could have been there? He didn't think so. After all, wouldn't she have made some sound? He imagined that his sweet, pure little sister would have proclaimed her utter disgust at what he was doing. He didn't think she would tell their parents; they had an unspoken pact that they didn't tell on each other, but if she had seen that, what must she think of him now?
Jimmy loved Jill with all his heart. Even more that his parents, he never wanted to disappoint her. To him, she was everything that a good girl should be. She had a pure heart, she treated everyone kindly, she was funny, she was smart, she was interesting to talk with, she was so very pretty and, he admitted to himself, extremely sexy.
So, what to do? He didn't want things to be awkward between them. He didn't want to appear at breakfast and, with a bite of eggs in his mouth, look over at his sister and see a disappointed look on her face. He didn't want to even think about her telling her friends about what she had seen, although he sincerely doubted that she would.
After grabbing a nearby cloth and carefully cleaning himself up, he pulled on a pair of athletic shorts and silently stole into the bathroom. Jill's door was shut and, he knew, was locked, as it always was.
Jill, now assuming that Jimmy had not seen her, had taken her clothes off and was laying on her bed, caressing her body, thinking about what she had just seen. She normally didn't allow herself to think about taboo things (like her BROTHER!!!) when she masturbated, but she couldn't get it off her mind. Her beloved Jimmy! So handsome. Those big arm and chest muscles that always made her knees weak! That COCK! She had never seen one in person, but she had never even seen a picture of one that big!
And when he ejaculated! There must have been a gallon of it! It just did something to her that she could not have enunciated. Knowing what it was -- MAN SEED! Sperm! The stuff that could go inside a woman and make babies! The essence of life! She had never really thought much of it before, but having seen her gorgeous brother shooting that thick, virile stuff had made her desire it -- to have it inside her, to touch it, to smell it, to taste it, to DRINK it!
She imagined that it might taste like vanilla pudding and that it would have magical powers, insanely arousing girls so that they would eagerly spread their legs, begging to be bred. She pinched her nipples and ran her hands slowly over her young body, spread her legs, and caressed her drooling pussy, knowing without a doubt that this orgasm was going to be by-far the best ever in her life!
She could feel the delicious tremors begin and knew that her orgasm was only seconds away -- what was that? Did she hear knocking? Then she heard it again. A gentle knock on the bathroom door.
"Just a minute!" she gasped, reaching for the light. "Jimmy?"
She desperately flailed around for something with which to cover her naked body, and finally grabbed her housecoat, threw it on and rapidly buttoned a couple of buttons randomly.
When she opened the bathroom door, Jimmy stood there in only a pair of athletic shorts. Her eyes darted to his well-developed chest and arms. "What, Jimmy," she whispered, sleepily rubbing her eyes, as if she had been in a deep sleep. "I was sound asleep."
"I...I just wanted to talk to you a minute..." He now realized that he hadn't planned on what he was going to say. All evidence pointed to the probability that she had been asleep and that he had only imagined her seeing him. But then he realized -- she had been up just moments before. The bathroom door didn't shut and lock itself.
Jill felt shaky. She had been nearing a powerful orgasm when he knocked, but she wondered if he had seen her, peering around the door, watching him stroke himself, after all.
"What about?" she asked, disguising her nervousness.
Jimmy entered the room and sat down on the bed. Jill sat next to him, realizing that her housecoat was buttoned haphazardly.
Jimmy noticed her fumbling with the housecoat and saw a quick flash of a portion of one of her breasts. "I don't know how to ask you this..."
Jill knew what was coming and sensed how embarrassed her brother was. She didn't want for him to agonize over this. She wished he would either just forget it or spit it out. "You mean in your bedroom while ago?" she managed to say before he could say anything else.
"Y...yesss," he stammered. "How much did you see?"
Jill could feel her face and chest flush. This was embarrassing. Why couldn't he have just pretended it never happened? "I didn't mean to, Jimmy! I wasn't spying on you! Don't be mad, please?" She felt as if she might cry.
"Jill, don't cry," he whispered, as he stroked her arm. "I just wanted to explain. I wasn't accusing you of anything. I accidentally left the door open."
"Explain?" she smiled. "Why explain? Doesn't everyone do that? I mean, not with the door open, but everyone does it, right?"
