Someone was tapping on the door to my bedroom. Oh shit, I thought, I've been busted. But I was sure Mom wasn't home.

"Robert, are you alright?" That sounded like my Sister. Rose had moved out to be with her boyfriend a year ago and that left just Mom and I.

"Give me a minute Sis." It would take that long for my erection to go down and to get dressed. Yes, I was masturbating. No, it's not something I usually do when alone in fact before this week I had never done it.

In my youth, I am now 30, I always had dates or girlfriends and sex was abundant. But lately, say the last year or so, things have been stagnant, in other words, no sex. And no I didn't just wake up one morning and decide to start doing it.

You see, I've had a problem since birth that no one knew about but me and of course one or two of those girlfriends if they bothered to look. One of my testicles hadn't dropped down to where it was suppose to be and as a result I needed an operation. The doctors would decide to either force it down or they would remove it altogether.

A sperm sample was needed to decide which of the two procedures they would perform. If the count was low, they would remove it. I had been told to bring in a sample or they would use a very large, intrusive, painful to the extreme needle on me. I was not too happy when I heard this option. I was not very happy with the first choice either as it was something I had never attempted before.

So anyway when I was alone in the house I would go down to my bedroom with a bottle of handlotion and a magazine, which I always had tucked under my mattress, and try it. This was the fourth time this week and I had yet to reach orgasm, I just couldn't do it, and I was sure my hand would begin to show blisters if I kept at it much longer.

"Open the door, come on."

"Come on what?" I said making a private joke and for once I thanked God that I didn't have a mess to clean up. Finished dressing I opened the door.

"Hi Sis, what's up?"

"Took you long enough, what, you got a girl in here?" Smiling openly she spied around the room till her eyes focused and settled on my bed. I turned to see what had grabbed her attention. Oh crap, the bottle of handlotion. She was starting to laugh now.

"You were jerking off weren't you?" But then she noticed the medical specimen container on the nightstand and her smile faded. "What's wrong?"

I was now visibly shaking. I broke down on the verge of tears and told her everything. She sat down on the bed beside me and listened. Afterwards we both stared at the floor. I was so ambarassed at being caught and absolutely terrified that maybe I couldn't have children. Not that I wanted any right now, but in the future maybe. Trying to lighten the mood of the room I made a stupid remark.

"So Sis, do you have any girlfriends that could give me a hand, wink wink, with this?"

Rose laughed. "They're all married."

"Well, I could hire a girl I guess, you know, downtown."

"Jesus Robert, you can't do that, God only knows what you'll catch." Sis suddenly stood up and reached under the bed where my hidden magazines were.

"How the fuck did you know they were there?"

"Mom found them years ago while changing the sheets you twit. I was talking to her when she did. Don't worry, it's alright, in fact I came in here quite a bit to look at them."

"You what? But there's only naked women in these."

"I know, but I needed something myself occasionally, you know, when I needed to make myself happy."

"Tell me you at least went back to your own room with them."

"No, I'm sorry if that bothers you but I usually did it on your bed. Something about the smell in here, it's different than my room." She said all this while flipping through the pages and her eyes now fell on a picture of two girls locked in a sixty-nine position.

"Holy shit, are you sure this doesn't do it for you Robert?"

"No, believe me, I've tried it, again and again and again. I can't believe you're looking at that, Rose, are you a Lesbian?"

"No, no, it's just a little kinky that's all."

"Cause Sis I mean if I could watch you with another girl doing that i'll bet that would do it for me." Rose looked over at me while putting the magazine down.

"Oh just fuck off." She was smiling though. "Yeah, i'll bet that would get you off too."

Rose suddenly looked retrospective and just stared at me for some time.

"Do you remember when we were ten or eleven alone downstairs we played I'll Show You Mine If You Show Me Yours?"

"Jesus that was twenty years ago, we were just kids."

"I know, I know. You even let me touch you, remember?"

"What are you bringing that up for?" Again Rose was quiet for several moments.

"Well, what if I help?"

"You're not fucking serious?" I couldn't believe what she was proposing. It hadn't even occured to me to ask her. I never thought of Rose in sexual terms, well, almost never. One time I had opened the door to her room without knocking and found her standing beside the bed. I apologized and started to close the door but she said it was okay and not to worry about it. She then asked me what I had wanted anyway.

We had a five minute conversation about what I don't recall while she slowly, very slowly, got dressed. I also remember, and there was nothing slow about this, the erection I got. It was almost painful standing there in her doorway as she moved around and at one point even applied skin cream to her breasts and the inside of her thighs. I had hoped she wouldn't notice but she did.

"Nice tent you got there." She called out to me as I left. Thankfully less than ten minutes later my girlfriend came over and one minute after that I was banging her on the basement floor. I remember substituting Rose's face over that of my girlfriend and I started to cum right away, frankly the best cum of my life.

The old memory had given me a new erection. Rose was still talking. "Look, all i'm saying is i'll give you a handjob, that's all."

"Rose we can't, it's just not right."

"It's okay, you're my brother and I want to help."

"However," she started to say while standing up, "this Cardigan outfit is expensive and I don't want your stuff on it."

Before I could say something she had lifted her sweater off over her head. She wasn't wearing a bra I quickly noticed, i'm keen like that. I couldn't help but notice something else too.

"God damn you're beautiful, I mean, Rose, stop it, put your top back on." I stumbled through this while she undid her pants and stepped out of them. Dark red cotton panties were all my Sister was left wearing. Seeing her beautiful body above me I realized any objections I had been harboring were now gone.

"There, now don't I look the part of one of those sluts in your magazine?"

"No Rose, you don't. You look a thousand times better. And besides, you're not a slut."

She smiled at me and noticed my erection as I stood up. "Well i'll take what you said as well as that," pointing to the bulge in my jeans, "as a compliment." Her hands moved to unbutton my jeans but I stopped her.

"I'll do it." I unzipped and then stepped out of them. I was trying to think of a reason to stop this but couldn't, I just kept picturing her with my dick in her mouth. I left my underwear on and started to sit down.

"Oh no you don't, we've got to have access here."

Quickly before I could object Rose grabbed my underwear and pulled them down to the floor. She now looked up at my erection which was just above her. She opened her mouth and inadvertently licked her lips and for one dizzying moment I was sure she had something else in mind. I tensed and blew a lungful of air out through clenched teeth.

"Hey now," she said while getting up. "I said I would give you a hand and I meant just that." She was smiling at my reaction though. Sitting down on the bed in an Indian position she patted the sheets in front of her. My heart by now was racing and she knew it.

"Just try and relax, okay, and oh yeah, hand me the lotion."

I sat down on the bed in the same position in front of her leaving about six inches between us and handed her the bottle. She scooted in a little closer and before I knew it she had her greased up hand wrapped around my cock and began stroking me.

Now to say Rose's hand gave me pleasure would be an understatement. My own hand could not compete with hers. She was so soft and I could see how right her technique was as she moved up and down the length of my shaft. I could feel my balls, well, one of them anyway tighten up. I wouldn't last much longer and soon I had my first orgasm in over a year. It was a rich one too.

"Oh God Rose i'm cumming."

"There, now you see, I told you I could help... oh shit quick, the specimen container."

She tried to clamp me off with one hand and reach for the container, which we had both forgotten about on the nightstand, with the other. Both hands would fail however as I shot my full load into the air and Rose, now off balance, fell onto the floor in her attempt. It was just so comical to watch that I couldn't help but laugh, and believe me, I laughed hard for the first time in quite awhile. Rose wasn't hurt and she smiled at me.
