Girls Watching Guys Ch. 04

Part Four: Masturbation with a Twist

Watching my brother masturbate the first time was unforgettable, watching him the second time was priceless, waiting to watch him a third time was simply unbearable. I needed to catch him so very bad, I felt more impatient than a kid before Christmas. Instead of the sight of Gary masturbating becoming more blasé with each viewing, it was becoming more and more urgent for me to see him. I was finding that spying on him was becoming an obsession of mine, even an addiction whereby I badly needed a fix. As I lay in bed at night I could envision him standing upright, completely naked, firmly grasping that shapely erection in his fist, pumping with great fervor, knees buckling, body shaking, groans and moans emanating from him until I watched his sperm flying through the air. I so needed to see him doing it one more time, just one more time. In two weeks time, it happened again.

This third time started off innocently enough, I swear I did not set this one up at all. We found ourselves home alone for the day again, and working in my room I went to ask him a computer question. Focused on my question, I opened his door without knocking and boy were we both surprised. He was in the middle of changing his clothes, facing the door. I came in at the perfect time, his underwear was all he had to take off and as I opened the door it was slipping down to his ankles. There in front of me, facing the door, stood Gary completely naked. Unlike the previous two times I had spied on him, this was the first time we both were aware of each other's presence, and that changed the whole atmosphere dramatically for me.

The reaction on his face at having been seen like this was priceless, there was a bit of surprise, but also excitement. Though as you might imagine, I didn't look him in the eye for but a second, my eyes quickly descended to get a good view of his wonderful flaccid penis right there before me. Oddly, he didn't try to cover himself or turn away to hide his genitals from my obvious gaze. Instead he stood motionless, and it afforded me a very good view of his penis. I suppose it was much more of a gaze at his naked crotch than I had intended to give. Finally able to tear my eyes away, as I turned to leave, I told him I was sorry. He quickly and playfully replied, "No you're not."

That response caught me off guard, making me laugh and look back at him with the question, "What do you mean I'm not sorry."

"By the way you were staring at my crotch, you didn't look the least bit sorry to me."

He had me there, and I admitted as much with a smile, "You might be right about that one."

And like that the talking stopped, the world stopped, time stopped. Him standing naked before me, underpants down at his ankles, me at his bedroom door looking back at him. When I say looking at him, I mean intending to look him in the face. My eyes however found their way back down to his soft penis and balls, and for the next few moments neither of us stirred. I was getting a very good view of his package, and I found it equally amazing that he was standing there letting me.

And just like that it happened. It twitched. I saw it, it twitched. And with one twitch it became larger. The world continued to stand still, my eyes fixed on Gary's dick, him standing motionless before me, obviously enjoying the attention of his sister's eager eyes. It twitched again, and all by itself, without any help from his fingers, it began to grow on its own. And he let me watch it happen. He let me watch, what a show off! I stared intently at this growing snake with no regard for Gary himself: his growing penis was all there was in the room. The first time in the shower I had seen it grow, but the view was obstructed by the shower glass. The second time I watched him, I had missed him grow erect when I had to answer the phone. This was the first time I got to watch it grow erect up close and with an unobstructed view. This wasn't even a reflection in the mirror, this was the real thing I was looking at.

I really can't say how long this lasted, how long does it take a guy to fully erect under such conditions? But here I was standing there watching him growing erect, but soon it was at its full state, pointing boldly skyward, the wonderful helmet and hole looking up at me. He proudly stood there naked before me, clearly enjoying showing off his manhood to a female, now in its new stage of erection. I was shocked with how freely and willingly he let me watch it like this, with no hint of embarrassment or trying to cover up. I would never let him look between my legs even for a second! Guys are so different than girls. I finally looked up at him, and found him intently staring at the expression on my face as I looked at his hard on. Realizing the situation, I could merely raise my eyebrows and say, "Wow."

Throughout this minute, the impulse to run away had struggled fiercely with the impulse to stay and watch him grow erect, and only after his member had engorged to full size and I had a considerable look at it in this state did the impulse to run win out. One final lingering look down at his wonderful shape and I was headed directly downstairs to take a deep breath and collect my thoughts. It had been a very astounding and erotic moment, and I'm not sure if I even breathed that entire time. What a sight that was, him standing in front of me naked, letting me see him grow erect. All his manliness on display for me. What a flush that had come over my face, especially when I realized how he was looking at my reaction the whole time. I betrayed too much of my womanly lust of his penis to him.

I sat down in the kitchen for nearly ten minutes trying to regain my composure until the sound of running water upstairs made me realize the fun wasn't over: He had gone into the bathroom to masturbate! I have no idea if he was originally intending to go into the shower anyway or if he was just changing clothes, and being seen naked by me made him have to jack off. Then again it really didn't matter. I had just confronted him face to face while he stood there naked, watched as he grew erect, and in a matter of minutes I would be watching him playing with himself for a third time. I couldn't help but wonder if this third time he would be any more aroused in his play knowing I had just seen him like that. As I slowly unlocked and opened the bathroom door, my hopes were met: He had decided once again to masturbate outside the shower in front of the sink, where I had a perfect view of his naked body.

He was standing looking at his manliness in the mirror, it was as stiff and hard as I had yet seen it. He was obviously at a very advanced stage of arousal, due no doubt to my watching him grow a few minutes earlier. The amount of precum on his penis was amazing; not just a small drop hanging half out of his pee hole, but a long wet stream ran halfway down the penis. There he stood admiring the way it worked its way down his shaft. Gary obviously was very interested with the image of how he looked when he was erect, several times now I had seen him looking at it this way for long stretches. Precum continued to ooze from his dick, and I don't know if him or I were looking at this scene more intently.

As he stood there like this, I began to wonder what his next move would be. Would he take a pee? Could he even pee with an erection like that? Would he do his little genital exam fetish on himself again? And oh, was he going to stick that toothbrush up his butt again? Or was he so ridiculously horny at this point, with all this precum oozing out, that he just had to take it in his hand and get to masturbating? While I was a bit sad that he didn't pee, and didn't give himself a doctor's exam, and completely ignored his toothbrush, I did not go away disappointed.

Lotion put on hand, hand was quickly put on dick and he began to stroke it with great speed. God was he ever turned on! The mere fact that I had seen him naked like that in his bedroom was enough for him to skip his normal foreplay games and go straight into his furious stroking. The squishing sound of his hand going up and down his shaft was ridiculously loud, and it was instantly joined by loud gasps and moans from him. Within a minute he had an absolutely furious orgasm, more intense than his other two I had witnessed. He had great trouble standing during it, and made the most incredible and painful grunts. Delightful! Sperm flew high into the air, far higher and in much greater quantity than the last time I watched, and was sprayed all over the counter top. The first stream of semen made it all the way to the mirror and dripped down. That was impressive to see.

As he stood there like that for a moment, supporting himself with his arms, I admired his white man spray all over the sink, and could not but feel flattered that I was solely responsible for his incredible response there in the bathroom. Standing naked in front of his sister for just one minute had caused him to get so ridiculously horny that he had a quick and furious orgasm. Whatever embarrassment I may have felt as I stood in his bedroom doorway face to face watching him naked was quickly replaced by a feeling of ultimate satisfaction. He was so incredibly turned on by me seeing him naked, and that made me feel really special, I have to say. For a moment I felt a special bond with him, and wanted to open the door, give his naked body a big hug, and let him know I enjoyed this just as much as he did.

All those bubbly feelings I had for him in that brief instant quickly vanished with what I saw him do next. He reached for and picked up an object on the sink that I had hitherto missed, being so focused on the precum dripping down his dick. Just like that my heart wound up in my throat, and the biggest feeling of embarrassment I ever experienced came over me. I surely thought I would die from embarrassment right there, I turned an even deeper shade of red then I had at my first gyno exam. In his hand he held a long round silver object, tapered at the end. He had my vibrator in his hand! My own private, secret toy. The one nobody else in the whole world even knew about. What the fuck!

I was frozen in place as I realized this, filled with outrage and disbelief and ultimate disgrace. The emotions were flying around and bouncing off the inside of my head, for a moment I didn't know what to think or how to feel, I was too in shock at the sight before me. My face continued to turn thousands of shades of red, I'm certain of it. That lousy bastard was rummaging through my things. He had been in my panty drawer, and found my vibrator in the back. And now he had it in his hand in the bathroom. Why on earth did he bring it into the bathroom with him, and why was he holding it only after he had shot his load?

If it wasn't for the curious nature of this last question, I would have burst through the door and slugged him one, the dirty little prick. But for some reason my curiosity made me pause for a second as I began to wonder what he had in mind that he should pick up the vibrator only after he had cum. He held it up to get a good look at it, turning it about and checking out every last bit of it. He was enjoying the view of that most intimate of my toys that had rubbed all my most private areas, and I knew those very thoughts must be going through his head. If he didn't know I masturbated before, now he had irrefutable proof. And his gaze upon the toy showed his brain envisioning exactly how it was used on me down there. How humiliating. It's one thing to spy on a guy when he's masturbating, but it's a whole other world when things are reversed and he has my own toy in his hand.

I suppose a description of my vibrator is in order, for the sexually curious out there, it was your typical old fashion silver vibe, smooth and straight in nature, not shaped at all like a penis. Not a bullet vibe by any means, it was a full sized one, even a little on the big end. I had bought it because it was a particularly wide one. I enjoy the idea of being stretched when I insert it, but then I've just admitted more than I wanted to. It was just your typical old fashion straight up vibe, and it had served me well through many hours of solo play. My only saving grace at the moment is that Gary had no idea just how frequently I used it.

But again, what was he doing picking up my vibe only after he had jerked off? I would have thought it would have become part of his sex play while he masturbated. And then the idea dawned on me. Was he horny enough to actually masturbate two consecutive times? A quick look down to his dick showed it still half hard, softened yes, but still sticking mostly straight ahead at three quarters size, some cum still hanging off the end. It was in limbo whether to go to sleep or get turned on by what its master had found. It didn't take long before I had my answer, as he continued to observe my vibrator closely, even pushing it through his fingers like it was being inserted (into my vagina no doubt!). His little man began once again to stand at attention at the idea of the vibrator being penetrated into certain orifices of mine.

It was a very embarrassing situation still, but I couldn't help but imagine the erotic imagery that must be going through his mind while doing this. It became obvious that by pushing the vibe through the round hole he made with his fingers, he was imagining it going in and out of my own vagina, because shortly after this his hand went down to his pubic bone, and he mimicked with his middle finger the circular motion of a girl rubbing on her clit. It was interesting watching a guy do that, pretending how a girl did it. But he was envisioning it was how I masturbated, and again I was very embarrassed. In fairness, I guess he had every right to be curious, I had been curious enough to actually spy on him doing it.

His penis was now somehow fully engorged again and pointing skyward, mere minutes after it had exploded with cum. Even as his sperm lay there still warm on the sink, he was obviously ready to play with himself a second time. I was getting a bonus showing this time around, and with some added flavor, he'd somehow be playing around with my vibrator while he did it. But how would he use it on himself? He surely couldn't have just brought it into the bathroom to look at it. With a twist of his hand, suddenly my vibe came to life, and I heard its slight and secretive vibrations. At once I felt the most unusual feeling of jealousy. It was my own private toy, and it was the first time it had ever serviced another person's fancy. The mere purring sound it made, so familiar to me in my own play, made my loins moisten rapidly.

He put it down for a moment, and reached into the shower to turn off the water that had been running. At first I was afraid this was the end of his jacking session, but he picked up the vibe once again and turned it back on. Without the sound of the running water interfering, the sound of its vibrations was so much louder and erotic. Still I felt my toy was cheating on me, and at the same time was enjoying that fact. Vibrating toy in hand, incredibly erect dick, with some left over cum still dribbling out his dick, it was an obvious union, and soon my little toy was put against the underside of his penis.

The look on his face at the contact was priceless. I really had no idea how guys might masturbate using a vibrator, but there he stood with it firmly pressed against the underside of his dick, standing almost motionless for the next two minutes, occasional noises coming from him. With the water now off, I could hear every little sound and exaggerated breath, he was but four feet from me. The proximity was exquisite. I was quite relishing the sight of him masturbating like this, and found it fascinating that a guy could use a vibrator too. His eyes were now closed and his hips slowly began to move as the feeling of the vibrations turned him on more. He was whimpering now, almost uncontrollably. A mixture of left over cum from his orgasm, and precum from the current vibrations slowly oozed out of his hole, which was a sight to see.

It took me a minute to realize my fingers were now very busily masturbating myself outside the door. Without the water running, and consequently hearing every breath of his, I had to try and be as deathly quite during my own masturbation so I did not give myself away. But rub away I did with very little self control, as my brother stood there masturbating for the second time in five minutes, with my own vibrator against his dick.

He held my vibrator now against the tip of his dick, I guess he liked the way the vibrations felt that way, and it almost seemed like it was too sensitive for him to take for long, but I looked on at the amazingly dirty sight as my brother's cum and precum were smeared onto my vibrator in this fashion. This was the first time my vibe had ever tasted man fluid before. And with that nasty thought my first orgasm came. So close to him, I don't know how he couldn't have heard me. I tried to be as very quiet as I could, but while one can suppress a moan or grunt, an orgasmic breath cannot be held back. I have to imagine he heard me and knew I was on the other side of the door watching him play with my vibrator. If he did realize it, he didn't let on, he kept my toy firmly against the end of his penis and continued to moan, even whispering, "Oh God." a few times.

I suppose the feeling was too intense, because he soon took it away and put it on his balls. I've had a boyfriend tell me that rubbing the tip of his penis against his hand creates an overly sensitive feeling in his butt of all things, and even makes him pee. If Gary is built the same way, he didn't pee, but then with how hard he was, and how much precum must have been blocking the urethra, I don't think it was possible for him to do that at the current time. For the next two minutes he held my vibrator against his balls, and slowly stroked his dick. It looked quite interesting watching him masturbate with his hand with the added feeling the vibe was giving to his balls. A look up at his face showed he was enjoying this way a little more then just standard stroking with the hand alone.

I suppose I should have been anticipating or expecting the next phase, but it quite took me by surprise. He took the vibrator behind his back, and began to point it to that forbidden hole on his backside. Was he going to insert that thing into his butt? Yes, he was. I have mentioned how my vibe is a particularly wide one, so the idea of him fitting it up that tight hole back there was shocking. I almost believed he wouldn't be able to do it.

He grunted a little deeper in nature when he first tried to push it inside him, it was a much different sound than I had heard him make previously. Maybe he wasn't used to being stretched like that, especially that first moment of penetration. The look on his face was one of considerable and obvious discomfort, and even embarrassment. Yes, come to think of it, standing there all by himself his face was growing flush with embarrassment at what he was doing to himself. A clear mixture of embarrassment and even a little pain as he stretched his opening slowly to accept my vibrator in his ass. May I say virgin ass? Because that was the impression I was getting. Not virgin to a toothbrush of course, but surely virgin to something this wide.

Eventually I could tell when the tapered part was finally fully inserted, and his butt was stretched to the maximum, he stood there for a minute a bit wide eyed, taking in how it felt to be stretched back there like that. He continued to grunt in this almost unpleasant fashion as he pushed my vibe ever so slowly into him. He didn't want to just put it in a little, he was working at putting this thing in all the way! Oh god, the image of my vibrator so very deep in his ass. The same vibrating object that had massaged my clitoris to countless orgasms, and spent countless hours inside my own vagina was now stuffed up his butt. I would call this anal play of his disgusting, except in fairness this wonderful object had spent considerable time up my own butt as well. That unique look on his face during the insertion was very similar to the one on my own when I did that same thing in my bed. How's that for a mental picture!
