Massage

A few hours later, Robert walked in the back door and his mother was setting the table.

“Hi, Honey,” she said. “Did you and Derek get any studying done, or did you play video games?”

“Of course we did, study that is.” He did everything he could to contain the excitement he felt about getting to race. That was as long as his father was gone the weekend he was supposed to race John's car.

She kissed his cheek and he looked down into the valley of cleavage that shouldn't have been so exposed. He didn't care what Carmen said, their mother had changed.

“Your sister needs you,” she said.

He approached Carmen's door like a chemistry final. One way or the other, he wasn't going to like it. She either wanted to chastise him for going down on Erica's ass, or she wanted to know what kind of pervert fondles his sister's ass in public, or both. He knocked and waited for her to say, “Come in.”

Carmen face was down on her bed with one leg folded up. Her heel was touching her butt.

“Robert... thank god. I need your help. I got a charley horse.”

“Really,” he said. “So how is that my problem?”

“It's not, but if you expect me to help you pass your finals, then you better get over here and start massaging my leg. And close the door.”

He knelt on the bed and knee walked up to her foot. “What....did you try some gymnastics?” He grabbed her ankle and pulled it away from her butt.

“Ouch, easy, I'm hurt,” she said.

“Where does it hurt?”

“I don't know exactly,” she said, and pointed in the general direction of her inner thigh. “Start there and work your way up.”

“Up“.he thought. Considering where she wanted him to start, there wasn't much up left. His hands hoovered above her leg. Skin is skin, he told himself and put both hands on her thigh. His thumbs pressed into her flesh and Carmen groaned.

“Why did a girl's thigh feel different than her shoulders or foot? Skin wasn't skin”. Thought started pumping into his fetish brain.

“Oooh, close, but go a little higher,” Carmen said.

He stared at the gym shorts that barely covered the globes of her ass. He wished he hadn't touched her earlier because now he knew how good her butt felt in his hand. It was only two inches away and Carmen was still coaching him to go higher. How much higher could he go? The further he progressed the more sensual and warm her leg seemed. She inch-wormed her body and her butt rose and fell. The lighter tone of her cheek emerged from her shorts and the seductive joining of thigh and butt taunted him.

“Mmm, now you're getting there. Keep going.”

“Um, I can't go much higher, that's your butt.”

“Now you're worried about touching my butt, when I'm in need, but in the school garage you didn't mind?” she said. “Just go a little higher and pretend it's mom's shoulders.”

“Like that would help“. He felt like a blind man defusing a bomb. His thumbs pressed deep into the warm, soft skin, and his penis acted like she wasn't his sister. Did she expect him to continue past where her butt cheek poked out from her shorts? She would stop him if he wandered off course, he thought, and continued.

His fingers were wrapped around the inside and the outside of her thigh, giving his thumbs leverage to dig deep into the back of her leg. They inched upward, testing that line which marked the beginning of her ass. His left hand would be in her crotch before his thumb was too far under her shorts, so he decided that's when he would have to be finished, or when she would say, “Hey!”.

Carmen moaned into her pillow, then said, “That's it, keep doing that.”

Both of his thumbs were completely inside her leg hole, forcing her shorts upward. He could see the edge of her underwear next to his index finger and he could feel the tight tendon that connected her inner thigh to her groin. That's where her pussy started. He cursed his dick for stiffening and tried to look away.

“Ohhhh...my god, that's it,” she said. “Ahh, ah, yess, you got it.”

The sounds, tempo of her words and her motions all made him very uncomfortable. If he didn't know it was his sister, Carmen, he would have thought she might have been having an orgasm.

“ Did she mean you got it, and I should stop, or I got it, keep doing that where you are”. He tried to play safe, and get away from that very awkward situation, so, he said,

“Okay, glad I could help,” then he got off the bed and turned towards the door to hide his evil erection. “I gotta go. It's time for dinner, anyway.”

“Phew, thank you,” she said. “You definitely earned some help studying.” Carmen rolled over and sat up.

“You thought Erica's butt was better? Tell the truth.”

“I can't,” he said, and left quickly. It honestly was a difficult choice. They were both sexy in their own way, but the choice became impossible if he was leaning towards his sister's. That would be creepy, especially after that massage. It also might hurt his chance of feeling the troubler's again. If he played his cards right, he might have the opportunity to fondle her in a bikini, right in front of his sister.

Damn his fucking p**n brain!!.

That night, Robert waited down stairs until he heard Carmen finish her shower. He had missed his after school relief because of his meeting with Patty and John Woodring; and after leaving Carmen's room he didn't have time before dinner, then they studied together. He stripped as soon as he got in the bathroom. The air was still warm, steamy and smelled like flowers. He opened the hamper and the panties he had seen through the leg opening of Carmen's shorts were right there on top. He still didn't agree with Derek, he didn't want to fuck his sister, but they weren't just underwear anymore.

Robert laid the panties out on the counter with the back facing up and the crotch hanging over the edge, then he got on his knees. He couldn't help himself, ever since he had stared between her legs and massaged her butt, it was all he could think about. He leaned forward like he had imagined earlier. The smell of Carmen's crotch was stronger than usual. His tongue shot out and sampled the cotton, while his hand stroked his dick.

“Eating your sister out wasn't as bad as fucking her, was it?”. A voice from the back of his head spoke out.

The moist strip of material entered his mouth. He sucked hard on what had covered Carmen's pussy minutes ago. She was face down, ass up and his nose was buried between her cheeks. He opened them and circled her anus with the tip of his tongue. His girlfriend, Rea Angel loved to have her ass licked while she fingered herself, and he imagined Carmen would also. His cum boiled inside his aching balls. They tightened and he stood quickly, aiming his bulbous knob into the narrow strip of underwear. He thrust forward and sprayed the back of his sister's panties, then he flipped the crotch around and put the stained cotton across his spurting slit.

When he was done emptying his load, Robert sat down on the toilet lid. He was trembling.

Carmen pretended to be asleep until Robert finished in the bathroom, then she went to the bathroom without turning on a light. The fact that she had conjured up such a plan was despicable, but there weren't words in her vocabulary for what she was about to do. She breathed in the strong scent for a full minute before she finally stuck out her tongue and tasted her brother's cum. Two fingers dipped inside her pussy-lips, then traveled upward, opening her labia all the way to her clitoris. It was swollen and throbbing under her fingers. She leaned back on the toilet tank and pulled her knees up. She hadn't even closed the door and she was spread eagle fingering herself with Robert's cum on her tongue.

“What the fuck is happening to me?”.
