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 blasΓ© 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."
