Son's Underwear Fetish

Boy discovered by mother masturbating with her panties.

Amanda, mother

Becky, 22, daughter

Jimmy, 20, son

Jason, Becky's boyfriend

Jimmy returns home after spending the first year of his college on campus. In his 2nd year he travels to college from home. He developed a habit of using college girl's underwear to masturbate with.

"Jimmy, what are you doing?!" Amanda asked, shocked at the sight of her son sitting on her bed with his trousers around his ankles and his hands in his lap with something pink in them.

"What...?!" Jimmy suddenly opened his eyes in utter shock, froze in fear and stared wide-eyed and froze, cupping his hands in his lap.

"What are you doing in my bedroom, Jimmy?" was his mother's automatic reproach as she approached Jimmy. "Oh, y...you have my...," she gasped covering her mouth.

Jimmy is completely frozen to the spot where he sat on the bed, petrified at being caught red-handed. He continued to stare wide-eyed at his mother like a deer caught in the headlights, unable to speak. He could not get up either.

It quickly dawned on her what is going on here. Gosh, her son was grown up. She bit her lip. In his hands he had one of her pink knickers, which was wrapped around a hard column...! She couldn't scold him. She didn't want to traumatise or scar him and affect his sexual pleasure for the rest of his life. She was wise enough to recognize that he's obviously interested in girls and she obviously is one of the most accessible ones. She decided to go easy on him.

"Oh, Jimmy, I'm so sorry. I...Hilda...Mrs White next door had to go out so I had to come back early. Look, I know what you're doing. It's ok, you're only... It's perfectly natural for a boy to be interested in girl's and woman's things. You're young and your hormones must be driving you crazy. Right?" She didn't know where she was finding this courage to say these awkward things. Her first instincts were to be angry.

Jimmy didn't answer; he just stared at the carpet. He's wondering why his mother wouldn't leave the room so that he can run back to his own room.

"Please put your shorts on," Amanda said and turned around to give him some privacy.

Jimmy was all too glad for the opportunity. After Jimmy was decent again Amanda sat on the bed next to her son.

"Jimmy, I'm not mad. In fact, I understand. I would be more worried if you

didn't

start to show interest in girls. You feel better after you stroked yourself, don't you?" When he didn't answer she moved closer to him and put her arm around his shoulders for comfort. "You need to now get a girlfriend, someone who you can touch and find out about girl things. Do you have a girlfriend? In college did you get friendly with a girl?"

Jimmy shook his head.

"I see." Jimmy was a clever boy academically but socially very awkward, especially where girls are concerned. Amanda was hoping spending time at college, away from home would bring him out of his shell; even find a girlfriend at long last. She was happy he wasn't distracted when he was at school by girls but then she was wondering about his sexuality when he still didn't have a girlfriend. But now she saw that he did indeed like girls, well at least their underwear! She almost giggled out loud. "Anyway let's have a look at what you took," Amanda held her hand out. When Jimmy didn't move she repeated the request. "I know you took my knickers. Can I have it back, please?"

Jimmy reached under the pillow, where he quickly hid it, and handed it over to his mother. To his horror and abundance of embarrassment she unfurled it out and held it aloft with two hands and made a great show of examining it.

"Good choice," she said with a mischievous girlie giggle; she wanted to laugh and couldn't help teasing a little. It was her sexy silky pink pair with a lacy crotch panel, which when she wore it revealed her dark hairy bush. She'd wear it on special occasions or when she wanted to feel sexy. Her husband also loved this pair...like father like son she smiled. She then placed it on the bed next to her.

"Look, I know you have urges at your age. So, if you want you can come in here and...and do your thing...you know, masturbate. But can you please try not to...get it on my knickers...or any other of my underwear you use? Use a tissue?"

Again Jimmy didn't answer. He knew what she meant and he was way too embarrassed to talk or face his mum. Besides he couldn't believe what he was hearing. She's giving him permission to wank with her knickers!

"Jimmy, honey, do you understand?" she kissed his forehead to reassure him.

Jimmy nodded.

"Hmm. You know, to me it looks like you must have developed interest in women's underwear before coming back home; in college perhaps? With the college full of girls you must have noticed some of them and made you want to masturbate. Did you masturbate with the college girl's panties? No, wait a minute you just told me you weren't friendly with any girls. So whose panties did you use?"

Jimmy didn't answer. His mother was a clever person and she was getting close to his secret.

"JIMMY! You didn't! Did you steal panties from the girls at your college?"

Jimmy's silence gave the game away. After all he didn't protest at the accusation!

Then Amanda had a thought. What about his sister? Has he been...?

"Have you...um, have you gone in to your sister's room and used any of her...her underwear?"

Jimmy nodded again; might as well confess as he surprisingly didn't seem to be in trouble. He'd only recently started to explore underwear drawers and wank off using his mother's and sister's variety of underwear...but mainly their bras and knickers. His sister Becky was a pretty 22 year old and had nice large tits that he ogled when he thought she wasn't looking. His mother was not drop-dead gorgeous pretty, but she was nice to look at and had a nice full curvy body and had larger breasts, but not overly big size. He'd noticed from the bra labels that his sister was size C and his mother was size D; not that he really understood what the sizing actually meant.

"I see. How long have you been doing this, using our underwear?"

"About 3 weeks," Jimmy finally managed to speak. That was soon after he moved back home.

"That's probably why you haven't been caught yet by your sister," she said, then paused a moment to think. "Jimmy, can I ask you to hold off from going into your sister's room for a bit, until I had a chance to talk to her and explain it to her? I don't want her to catch you, like I did, before I had a chance to explain it to her, she may not be so calm. You know what I mean?"

"No...!" Came the pained protest and the horrified look on Jimmy's face.

"Trust me. If I can explain to your sister the need for boys...she'll understand. I'll make her understand that you need to use her knickers and bras to masturbate with, that it helps you to relieve yourself. I'll explain that some boys are like that."

"But..."

"I'll explain that you'll be using my underwear also, so she won't be so freaked out," she explained. "Jimmy, do you and your friends try to look up girls' skirts at college?"

"What? No...!" protested Jimmy.

"Jimmmmmy...," Amanda demanded. She of course knew boys. "You know, Becky also knows. In fact she'd told me before that boys keep trying to look up her skirt and also stare at her breasts...previously at school, now at college and else where. I told her to wear longer skirts and dresses and not to wear low-cut tops; but she says that's for grannies!" Amanda laughed. "Silly girl. So don't worry, she knows boys like girls' knickers and bras. So will you hold off from going to her room until I have spoken with her?"

"OK," he said grudgingly.

"That's a good boy," Amanda said happily and squeezed him and gave him a long kiss on his cheek.

Jimmy's cock had deflated after being caught red handed, but it began to stir again at the prospect of future wanking with his mother's and sister's knickers and bras. Now it was hard once more and poking up from his shorts, especially after feeling his mother's soft breast on his arm.

"And whilst you masturbate with our things, you need to get a girlfriend. Do you hear?" Amanda was becoming a little less embarrassed herself. "You must have heard what a girlfriend can do for you and what you can do with her?"

Jimmy nodded.

"She can help you to relieve the sexual urges you feel and you get to feel her up!" his mother said chirpily and sporting a silly grin. Then she had another thought to help her son, to reassure him. "Jimmy, it's not only you. Your father still looks at other women...AND girls and has naughty thoughts! But when he...um, needs to relieve

his

frustration he can turn to me. I help him out. So you see? You should get a girlfriend quickly. You're 20 now so you should have a girlfriend by now."

Jimmy was stunned that his mother was talking so explicitly about her private bedroom things.

"I'll try, but I can't just ask her to...you know."

"No. You don't ask a girl to do naughty things straight away. You will need to make friends with her, then make her into a special friend. And only THEN do you get her to help you masturbate...and you get to feel her up and see her underwear!" Amanda knew she was teasing but she was having a bit of fun with her son.

"Actually I can't. I can't talk to girls!"

"Really? We'll talk about it later. In the meantime I guess I ruined your moment. Do you still want to..." she didn't finish since she saw the tent in his shorts. "I see you need to", she pointed to his erection. "Look, I'll leave you here for a while and you do your thing. And here, you may need this," she laughed as she handed her son her silky pink knickers. "And these," she placed a box of tissues next to him on the bed.

"T...thank you," Jimmy managed to say as he gingerly took his mother's sexy underwear,

"You're most welcome," Amanda said giving him a long hard kiss on the cheek, and mischievously a quick peck on his lips, stunning the poor boy further. She'd never kissed him on the mouth before.

Amanda got up and left. She was about to close the door shut but her curiosity took the better of her. She left the door just a whisker ajar, enough to peek into her bedroom unnoticed by her pre-occupied son. She saw him quickly slip his shorts down, sit on the bed and pick up her knickers. He held it up in both hands and examined the delicate article. Amanda was amazed to see her son rub her knickers on his face before wrapping it around his rampant angry looking cock. She couldn't believe that her son was now a young man, so big and hard -- no longer the little playful thing of a toddler.

Jimmy closed his eyes and began to stroke his hard cock encased in the soft material. Amanda couldn't believe what she was doing spying on a boy's very private moment, and she couldn't believe what she was seeing. Without even her knowing her hand went to between her legs and stroked herself with her middle finger. It wasn't long before Jimmy and his mother came; Jimmy quickly swapping the knickers for a tissue just in time to ejaculate into.

"Becky, I need to talk to you about something important. It's about your brother," Amanda said, sitting on a chair opposite Becky, who was sitting on her bed.

"Jimmy? What's happened to him?"

"No, no. Don't worry, nothing's happened to him...well other than him growing up," Amanda said enigmatically.

"Eh?"

"I mean, your brother is 20 now...and he's a young man, no longer a teenager."

"What do you mean, mum?"

"Let me put it this way. You know recently you told me how the boys in your college keep trying to look up your skirt and keep looking at your breasts?"

"Y...yes?" Becky replied cautiously, curiosity rising.

"Well, Jimmy is a boy. He likes...he's finally taking interest in girls; but also girl's underwear," ventured Amanda.

"That pervert. Who's he been caught looking up?"

"No, it's not like that. He is now at the stage where he's expressing his natural desires. Natural urges. Just like you do."

"But I don't try to look up girl's skirts."

"No, but you are interested in what's behind a boy's trousers..." her mother sniggered.

"MOTHER!"

"Now, don't be coy. That's also perfectly natural. No, what I'm saying is that Jimmy doesn't have a girlfriend so he doesn't yet have an outlet for his urges, one a girlfriend would provide."

"What's that got to do with me?"

"Jimmy likes to use a girl's underwear to help him...you know...to masturbate; and I want you to let him use yours," Amanda spoke quickly, nervous at her daughter's potential reaction.

"WHAT?!"

"Becky, listen. I caught him earlier today in my room with one of my knickers in his hands and he was masturbating with it. We had a talk and I suggested it would be ok if he needed to do that. Well, until he gets a girlfriend."

"You want him to wank and cum in my knickers? He's gonna ruin them. And anyway, that's just gross!"

"Becky, he's already been using our underwear for the past 3 weeks. He's been careful and uses a tissue to cum in."

"No way! That pervert. I'll...I'll..."

"Becky, we need to help him. He's your brother," she tried to explain and to calm her down. "You're alright since you have a boyfriend. I know what you do for Jason...with your hand...and your mouth."

"MUMMY! I DON'T...I..."

"Don't deny it, Becky. That's why you

got

a boyfriend, isn't it? You're curious about penises and you have your female urges. And Jason does things for you down there? Most youngsters at college do these things. And when Jimmy has a girlfriend she will provide him with the relief that you provide

your

boyfriend."

There was no point in deny it anymore. Becky just sighed.

"So if you spot him in your room with your underwear, or if he borrows them, I don't want you to say anything. Let him finish. Understand?"

"Yes, mother," Becky grudgingly accepted.

"Good."

"But tell him to get a girlfriend," Becky shot back angrily.

"I'll talk to him," bargained Amanda.

So, Jimmy had a free reign in accessing his mother's and sister's bra and knickers to masturbate with.

----------------

The next day Amanda went to Jimmy's room to have a talk to him.

"Jimmy, I had a talk with your sister and she has agreed for your to use her underwear. But she isn't happy about it; she says you need to get a girlfriend. And I'm inclined to agree with her. It's not healthy for you to be expressing your urges through your mother's and your sister's underwear."

Jimmy didn't respond, embarrassed to be discussing this topic.

"Tell me, what did you do when you were living on campus at college? When did you got the urge to start using...you know, underwear?"

"Muuuum!"

"Jimmy, I need to know. Not only as your mother but as someone's whose underwear you are using. So out with it."

"About 6 months into my year at college. The girls just wear what they like, not school uniforms any more. They wear short skirts and low tops and I can...see their underwear. All the time." Jimmy spoke whilst only looking down at the carpet.

"I know. I tell your sister to dress more respectfully, but she...oh, never mind. Go on."

"Well, then I realised that many girls didn't lock their door at campus so I used to sneak in their rooms when I knew they were in class to...you know."

"I see. But didn't you try to make friends with any of the girls? You know, make them your girlfriend."

"I can't mum. I'm too shy. I just look at them and I see their..."

Amanda nodded. "I see. But if you had a girlfriend she'd let you see her underwear...and do even more for you, eh? You know what I mean?" Amanda can't believe she's having this conversation with her 20year old son now. It was too embarrassing to talk about the subject of sex when he was younger so she had only vaguely spoke about it, thinking he'll pick it all up at school -- through other boys and school lessons. And anyway he was studying so hard that she thought it was good to let him continue, why distract him with girls? But now she has to PUSH him to get a girlfriend.

Jimmy didn't answer. It was too scary to be chasing girls. What if they laughed at him? Called him a pervert? He didn't think he could take that kind of rejection.

"Look, Jimmy, you have to realise that this is only a temporary arrangement. In the meantime make an effort to get a girlfriend. OK?

Jimmy nodded.

Part 2

Of course accidents happen and there were times when Becky, and her mother, found stained knickers that were put back in their drawers. Becky understandably was unhappy when she picked a new pair of knickers to put on to find her brother's dried cum on them. She complained to her mum, who had a quiet word with Jimmy.

"Jimmy, you know what I had said about using tissues when you relieve yourself?"

"Erm, yes, mum?"

"Well, I don't think you are doing it all the time. Becky AND I have found our clean underwear...shall we say...used by you, in our underwear drawer."

"Oh..."

"Please try to use the tissues."

"Ok, mum. I'm sorry. But...but sometimes I can't stop," he said coyly.

"Just an idea. If you

need

to ejaculate in our panties, use the used panties from the laundry basket in the bathroom, OK?"

"Really?" Jimmy perked up.

"Sure. They need to be washed, so what the heck."

Sure enough, Jimmy had a wonderful time with the used panties. He even found the musky smell somehow alluring. He even ventured to actually sniff the panties, making his head spin at his daringness.

------------

Daily Jimmy masturbated in either his sister's or his mother's room, sometimes in his own room as well with one or two items of their underwear. His mother started to get used to seeing him in her room masturbating and she would leave him to it to finish.

But this day she walked in and was in a hurry.

"Oh! Sorry sweety. Erm...I just need something. I won't be a second," Amanda said.

Jimmy still felt embarrassed at being caught out masturbating, so he covered his crotch with his hands, hiding his erect cock and his mother's knickers that was around it, and didn't look at her. He couldn't do anything about his mother's two bras on the bed that he had been ogling and touching to further arouse himself.

But that changed when he saw his mother, standing by her chest of drawers with her back to him, reach under her skirt and pulled down her panties -- he noted she'd been wearing black panties. She reached into her underwear drawer and took out yellow panties. Spellbound he watched her step into them one leg at a time and slide them up under her skirt. He was transfixed. He'd never seen anything more erotic.

She threw him her warm, used knickers to him. "Here, use this. You can cum in them if you like. When you're finished put them in the laundry basket." She was so casual about it!

Automatically he raised both his hands to catch the underwear, unwittingly exposing his erect cock and the knickers he was already using. She laughed as she left her bedroom, closing the door but partially leaving it ajar. But she stood in the hallway to listen. And sure enough she immediately heard loud groaning as her son had a massive orgasm. It was too much for the poor horny young boy.

-----------

But one day Becky walks in on his brother in her room. Nothing unusual in that, Becky was also getting used to catching him in her bedroom masturbating with her knickers. She would sigh then grudgingly leave him to it for a while until he finished.

But this time was different. This time her brother was totally naked! He was lying face down and moving his hips against the bed.

"Becky! Becky!" she heard him cry out as he ground himself harder against the bed.
