Even though his sister had told him she would never let him finger fuck her again, or jerk him off, Sammy considered her a sex Goddess.
Every time he saw her, his prick got hard. The smell of her hair could almost make him come right in his pants.
So it wasn't surprising that he began going into her bedroom when she wasn't home. Just being in that room made him wildly horny. After all, it was there that he had gotten his first hand job and had fingered his first pussy.
Sammy would sit on the bed where he'd sat when he'd reached into his sister's cunt. He would try to remember every second of that fabulous experience.
Then he would pull out his prick. Thinking of his sister's gentle touch, he would jerk off.
Once, while prowling in her room, he found a pair of her underpants lying on the bed. The sight of that little garment thrilled him. They might be the very undies she was wearing when we jerked each other off! Sammy thought.
He picked them up. They could be the underpants Pat was wearing that wonderful evening! In any case, he found them to be very exciting.
It seemed strange to be excited by a pair of underpants. As Sammy held them in front of him, he began to understand his interest. After all, didn't these panties hug his sister's pussy and ass? And wouldn't he love to do just that?
He looked at the crotch of the panties and imagined his sister's twat in there.
Then he held the garment to his face. The odor of Pat's cunt hit him like a ten-pound hammer. The underpants began to seem like a sexual treasure to the sex-starved boy.
He whipped out his prick. Then he laid the panties over it.
The cool material draped across his hot prick gave him a kinky thrill.
Next, Sammy wrapped his cock with the undies. They were so smooth that they were the perfect thing to jerk off into, he knew. But then he had another idea.
His imagination embarrassed him. What he was thinking must be the most perverted thought a kid could have! Still, he had to do it – he had to try the panties on!
With shaking fingers, Sammy undressed. The thought of what he was about to do made his cheeks burn. But it also made his cock throb powerfully.
When he was naked, he picked up the panties and stepped into them. Then, when he pulled them up, he realized the full power of that garment. Save for the hot feeling of his sister's hand on his prick, this was the most exciting sensation he'd ever felt.
The bikini panties fit him pretty well. His ass filled them snugly. The crotch of her panties held his balls tightly. And since they were cut so low, his prick could stick right over the top of the sexy garment.
Sammy went to the mirror and looked at himself. What he saw made him even more embarrassed, and more excited.
The sight of himself in those panties made Sammy grab his prick. Then, still standing in front of the mirror, he began to jerk off. As he pulled and pushed the skin on his cock, the panties massaged his balls. And the nylon material crept up into the crack of his ass.
When he came, a fountain of jism exploded from his cock. It landed on his sister's dresser. One shot even hit the mirror.
After he drained his lust through his cock, Sammy felt sort of silly in his sister's underwear. Avoiding his reflection in the mirror, he took off the panties and dressed. Then he mopped up his gism and left his sister's room.
He promised himself that he would never do anything so weird again. Naturally, that promise only lasted until the next time he got horny.
Again and again he visited his sister's room. Before long he was putting on her bras, slips and pantyhose as well as her underpants. As long as he couldn't get the real thing, dressing in his sister's underwear and jerking off seemed to be the next best thing.
One time, as he stood in front of his sister's mirror in her underwear, he heard someone come in the house. The footsteps were loud, heading for the stairway.
Sammy had already begun to jerk off. In fact, his jism had begun to churn within his jerking nuts.
But the thought of being caught dressed as he was made him forget his prick. As fast as he could, he began to pull the underwear off.
Fortunately, he was only wearing a pair of panties and a bra. He managed to get out of them in a matter of seconds. In a few more seconds he had them put back into the drawer.
But now he stood naked in his sister's room. And someone was already climbing the stairs.
Sammy looked down at his clothes. There was absolutely no way he could get dressed before who ever was on the stairs reached the door of the bedroom.
Sammy suddenly realized that it must be his sister climbing the stairs. His mother and father were both at their jobs. That was a relief. If he was to get caught, he would rather it be by his sister. They already had a secret, and another wouldn't matter much.
So Sammy just gave up hope of getting away. At least he wouldn't be caught in her underwear.
"What are you doing?" Pat asked as she stepped into the room.
She looked at her brother's stiff prick, then at his clothing scattered on the floor.
"I was just looking at myself in your mirror," Sammy said. "Do you think I have a good build?"
"Why aren't you looking in your own mirror?" Pat asked.
"Yours is bigger," he said looking at himself again. "My prick really is pretty big, isn't it?"
"You'd better get out of here," Pat said.
Sammy could see that she was staring at his prick. This might be a good time to get another crack at her pussy, he thought.
"Let's jerk each other off again," he said.
"No!" Pat said sternly.
"Come on. It was so much fun the last time," Sammy argued.
"No, no, no!" Pat yelled. "Now get out!"
"Gee, what a grouch," Sammy said as he picked up his clothes.
He was disappointed, but it had been exciting to have his sister see him naked again. And now, rather than being glad he had gotten out of her underwear before she got to her room, he wished she had caught him dressed up like he'd been. That would give her something to think about!
So, alone in his own room, Sammy finished what he'd started in his sister's room. The thrill of confronting her with his clothes off – and his prick stiff – made jerking off special.
But Sammy knew that something would have to change. If he kept up as he'd been going, he would turn into some sort of pervert. There was only one cure – to get fucked!
