Tests

It was Saturday morning. Tom woke up and heard the sounds of a blow dryer in the bathroom. He went downstairs and made some coffee then waited.

Val came down several minutes later. She had on black yoga pants and an over-sized pink t-shirt. Her hair was down around her shoulders.

"What's your plans for today?" asked Tom.

"Oh, going to lunch with some friends in a couple of hours. Just gonna watch TV and lay around until then. Why?"

Tom decided it was time for his first test. He went for broke. "Well, it's just odd that every morning, you have me spank you good and hard to keep your ass in a good firm shape, but you haven't asked me this morning yet."

Val looked at Tom. She thought for a moment. "Oh yeah," she said.

"Yep, if not for the daily spankings, your butt would be saggy and gross. Now come lay across my lap." Tom pushed his chair back.

"Yeah, let's get it over with." Val came and lay across Tom's lap with her ass in prime spanking position.

Tom looked down at his step-sister's firm bubble butt and felt his dick start to stiffen. He raised a hand and slapped her ass hard.

"Ow!" said Val.

"Val, stop hiding it," said Tom.

"Hiding what?"

"You know this turns you on. It's been obvious since day one. You love being spanked. It makes you horny. Admit it."

Val swallowed hard. "You're right, but it's embarrassing."

"Why?" asked Tom. "It's natural for a girl with a great ass like yours." He smacked her again and again. Both of them grew aroused.

After a few minutes, Tom finished. Val stood up and rubbed her ass.

Tom decided to let his pervert flag fly. "Your hair looks awful dry."

"It does?" gasped Val. She was very vain about her looks. She walked over to the oven and tried to see her reflection in the glass door.

"Yep, good thing I'm here to help."

"How?"

"Nothing, and I mean nothing is better for your hair and scalp than semen."

"Gross! Really?"

"Of course, you're the one who told me that! You said you've known it for years, but never had the courage to ask anyone to cum in your hair, but it's called a 'hair job,' and it's perfectly normal for you to let me or any other guy stroke ourselves off with your hair and cum in it. It's not even sex really; it's more of a beauty treatment."

"Oh, yeah, I don't know why I've been resisting it," said Val, "But I've already showered."

"No problem, cum absorbs well." Tom stood up and took of his pajama pants and boxers. He sat back down and looked at his embarrassed step-sister trying not too look at his erection. "Come sit between my legs and lean your head back against my dick."

"OK, I could use it today with my hair being so dry." Val walked over and sat on her knees, facing away from Tom. She leaned her head back.

Tom wrapped Val's soft, silky hair around his cock and started stroking his cock. "It's OK this turns you on too," he said. "Even though this is non-sexual for most people, the fact you have a fetish for it is nothing to be ashamed of."

Val just sat silently as Tom rubbed his dick with her hair and pushed his erection up against her scalp. "You have a fetish for being spanked and giving guys hair jobs. It's OK, nothing to be ashamed of even if you'll orgasm when you feel cum hit your head." He pushed his cock against her scalp and kept massaging his cock with her hair until he blew his load against the back of her head.

"Ohhhh!" moaned Val as she felt the hot cum hit her scalp.

Tom shot a few more loads until he was spent. "All done. Just massage it in really good."

Val leaned forward then stood up. She massaged Tom's semen into her scalp and hair.
