Tonya unlocked the door, and stepped inside out of the rain. It was a dreary afternoon, and she'd had a rough day with her job. It was days like this that she wished she had went to college instead of going to work in the local warehouse as an order picker.
She saw her brother Tim's Car parked in the driveway when she pulled in, and figured he must have gotten the day off because of the rain. Tim worked for a landscaper, and there was only so much maintenance they could do in the shop. It had rained the past three days, so they were probably as caught up as they were going to get for the time being.
Tim and Tonya lived with their Mom in a 4 bedroom house in a fairly upscale neighborhood. Tonya had gotten an apartment shortly after graduation, but had given it up. The apartment was in a less than desirable section of town, and after it was broken into for the third time, she decided on moving back home with her Mom.
Likewise, Tim had moved out after his graduation two years before Tonya, and due to some financial difficulties, had also returned home. It wasn't the cool thing to do for a young guy, but Their Mom was really laid back, and didn't mind a few overnight guests from time to time. Tim's regular girlfriend stayed more nights that she stayed at her place as it was.
Tim and Tonya's mom, Sue, often was out herself, and worked odd shifts, had quite a few business trips, and afforded Tim, and Tonya with plenty of privacy of their own. Tonya had had friends over for the weekend almost every weekend since moving back in.
Tonya hung up her rain coat, hung her keys on the hook by the door, and headed upstairs to change. When she passed Tim's bedroom, She saw the door was open a tiny slit. She couldn't help but catch a glimpse of Tim lying on his bed nude. She paused for just a moment, and then continued on to her own room to change from work.
'Wow. He sure has filled out, and gotten muscular since he's been working for the landscaper' Tonya thought. 'He has a nice tan too!'
Tonya closed her bedroom door behind her, and took off her shoes and socks before peeling off her tight, wet jeans, her shirt and thong. She normally didn't care too much to wear clothes right away when getting home from work. Her normal routine was to strip, and get a shower, then lounge around her room in the nude until Mom got home, then get dressed, and help make dinner. Today Tim was home though, and she grabbed a towel, and donned a pair of spandex running pants, and halter top to walk to the bathroom in. Tim was kind of a pervert, and she'd caught him copping a glance or two in the past. Better to be modest this afternoon.
She closed the door, and considered locking it, then dismissed the idea. Tim hadn't done anything perverted in a while, and he seemed preoccupied with whatever he was watching on his TV. She should be ok. She turned on the water, and adjusted the temperature nice, and hot. She peeled off the running pants from her full hips and the halter top from her ample breasts, and hung the towel up where she could reach it from the shower. She stepped into the stream of hot water, and was enjoying the warmth when Tim knocked on the door.
"Tonya, when did you get home?"
"A few minutes ago, why?"
"I just wondered. I didn't hear you come in. How long are you going to be? I have to go really bad!"
"I'll only be just a minute. Tie a knot in it! I won't be too long. I just want to wash my hair quick, and it won't take long"
Tonya had flowing auburn hair, and Tim knew it would be more than a few minutes.
'Um, What I've got to do, I can't tie a knot in Tonya, and I really have to go bad, just stay in the shower a few minutes"
"Come on Tim! You know I don't want you in here when I'm in the shower! I know how you are!"
"Aw, come on sis! I really have to go!"
With that, Tim opened the door anyway, and walked across the large bathroom to the toilet, dropped his boxers, and sat down. He could see Tonya's silhouette through the translucent shower door, and immediately got aroused. He'd had the hots for his sister ever since the previous summer when he caught her, and one of her friend's skinny dipping in their pool. He started getting an erection, and playing with his hardening cock.
Tonya hadn't heard him enter the bathroom. She had assumed he went back to his room to wait for her to finish. She hurried as much as she could not wanting to keep Tim too long from using the bathroom. When she shut off the water, and stepped out of the shower, she grabbed the towel, and then saw Tim on the toilet rubbing a huge hard on.
"You fucking pig! I told you to wait, and what the fuck do you think your doing?" Tonya shouted.
'Oh, come on Tonya, you act like you never seen me jack off before! I know you used to watch me!"
"I did not!"
"Yes you did! I saw you peeking through the door a few times. You didn't think I knew, did you?"
Tonya almost dropped the towel she was trying to wrap up in at that. She had seen Tim masturbate before, and had watched as he did. She had come home early from school, and caught him in her room smelling a pair of her worn tights and stroking his cock. She had no idea that he knew she was watching though. She had sneaked up to his door a few times after that and had watched him jack off in the light of his TV. Tim had a large collection of pornographic movies, and watched them frequently after lights out. Tonya could often hear his bed creaking, and would slip out of her own room, and sit in the hallway, and peer through the gap in Tim's bedroom door. More often than not, she masturbated herself while watching her older brother. He did have one Hell of a dick on him!
"You could stop that you know!" Tonya said to him as Tim continued stroking himself without missing a beat. "You're a real sick fucker, you know that?"
"Aw, you like it!" Tim just laughed, and continued. He was actually close to climax from seeing Tonya's gorgeous nude body before she managed to get the towel around herself. The fact that she caught him pushed him right o the edge, and he started ejaculating as Tonya was passing him to grab the clothes she had worn into the bathroom. A stream of warm semen hit her leg as she walked past.
"You sick Fuck!" Tonya said as she reached down, and swiped the glob away. "I can't believe you just did that!" She stomped out of the bathroom, and slammed her bedroom door behind her.
Once inside, she realized that the sticky glob of Tim's semen was still hanging from her finger. She looked at it, and reached for a tissue to clean her hand off. "What a sick fucker! Jacking off while watching me like that!" She thought. "I wonder how often he does that?" She didn't want to admit it at the moment, but she'd had more than one fantasy of being taken by her brother over the years. Even the previous evening, she had lain awake in bed while Tim and his girlfriend Amy were fucking. Listening to Amy moan, and squeal. Just a little bit jealous that she was in bed alone while that bitch was getting the fucking of a lifetime! Tonya had retrieved her vibrator she kept under the mattress, and used it to bring herself to orgasm, listening to the activities in the next room.
