He decided to try and get out of his situation by waking his sister up. He thought it would work like magic, but alas, she didn't wake up. He tried to mentally scream again, harder and louder, and once again she didn't budge. His efforts were fruitless and futile. This meant only one thing; he would have to wait until she awoke naturally. With his new-found patience, Jeff waited. He watched her chest rise and fall and listened to the rhythmic sound of her breathing. Her soft breasts gently rose and fell as well as her hips, which shifted from side to side in her slumber. She snored softly, and he could smell the aroma of her sweat mixing with the scent of her perfume.
After a few hours of watching her sleep, he noticed that the smell was coming from somewhere deeper within her, deeper within him. At first, he assumed it was just a vaginal odor, but it smelled different somehow. Not bad, just... different. Something about it reminded him of something. Then it hit him like a brick wall; it smelled like semen! The odor was faint, but distinct. It was strong enough to make his mouth water, but not strong enough to awaken his sister. He pondered, what if he made her cum? Would that make her wake up? If he gave her an orgasm, perhaps that would rouse her. It wouldn't be so bad if she woke up with an orgasm anyway; she might not mind him making her cum in her sleep every once in a while!
As Jeff continued thinking about this for a long time without realizing what he was doing; he was becoming wetter and wetter! The scent was growing stronger by the moment! He was literally dripping with her cum! The smell of semen and pussy juice were so strong in the darkness that it became too distracting for Jeff to concentrate on anything else! He had gotten so lost in thought that he hadn't even noticed that his sister was now moaning slightly in her sleep! For the first time since he woke up; his sister had moved! She was moving her hips back and forth in unison with some kind of rhythm! She was having an intense wet dream!
The fact that his sister was trying to fuck while asleep practically drove Jeff over the edge! He didn't know why it turned him on so much; it just did! His sister's moans were getting louder each time she thrust her hips back and forth!
Jeff had grown so wet. His sister kept thrusting herself back and forth like she was trying to meet someone or something behind her! Her hips slammed into the mattress with such force that she literally rocked the bed! She was getting closer and closer... closer... closer... closer...! Jeff was getting close too! His own excitement was building rapidly as his sister reach the peak of her orgasm! She came so hard that she literally screamed; a soft moan mixed with an agonized scream! Jeff felt cum spraying out of him like a geyser! He came harder than he ever had before; each spurt seemed more powerful than the last! His orgasm seemed to last forever; Jeff could feel himself tingling for what felt like an eternity after it ended!
Finally, his sister's spasms subsided; she stopped moving and simply lay there breathing heavily for what seemed like forever. Everything within Jeff began to calm down; the feeling of his sister's warm juice flowing through him slowly subsided until it disappeared completely. It took Jeff a while to realize what had just happened; he came so hard that he passed out from exhaustion from all the effort it took just to cum!
Jeff's sister eventually woke up right before dawn with a huge smile on her face after having an incredibly sexy dream. She didn't realize what had happened until she touched herself and noticed that she came pretty damn hard while sleeping! She felt so good about herself after that; she couldn't help but smile even more as she slipped back into a deep sleep.
