*****
I had just turned back into a guy. Then minutes later I'm a girl again and I'm blowing some old man. Whenever I'm near a guy as a girl I seem to be overwhelmed with lust, despite the fact that I'm not attracted to men at all. And I still don't know what's triggering these transformations. Thank god the last three backyards I went through happened to be empty.
Now all I need to do is cross the street to my house, and somehow sneak in the back door and up to my room without anyone seeing me. While holding up the pants that are too big for me in my girly form and the towel that is the only thing covering my big perky breasts. I looked both ways from my hiding place behind some shrubs, then made my way across the street and to the side of my house, quickly slipping in the back gate.
I made my way to the sliding glass door in the back when the tingle hit me again. I recognized what was happening this time and looked down. My breasts began to shrink, and my waist began to expand. Hair started to show on my chest and stomach. In moments I was my usual male self again. My original self again.I heaved a sigh of relief so strong that it almost became a sob, dropping the towel I had used to cover my rack, and went inside. I went straight up to my room and, too physically and emotionally exhausted to do anything else, I stripped off my pants, lay down and went straight to sleep with the sun still high in the sky.
I woke up hours later, dehydrated and groggy. The taste in my mouth was worse then the usual bitter morning breath. I could see stars through my bedroom window.
Suddenly the events of the day came crashing back to me. But it all seemed much hazier now, laying in my own bed in my own house. It was all way too weird to believe and far easier to dismiss it all as a bizarre dream.
The house was dark and seemed nearly silent at first. But as I lay there in bed trying to decide whether I wanted something to drink more then I wanted to just lay there, I started to hear something. It sounded like box springs, which probably meant my parents were doing it. That was nothing I wanted to know about, but now that I was awake I felt too dehydrated to get back to sleep. And if staying here meant listening to that, I might as well get up. So I slipped on a pair of boxers and tiptoed out of my room and passed my parents bedroom. I went downstairs to the kitchen cracked open the fridge as quietly as I could. Nothing looked particularly appealing so I downed two glasses of water and started my silent way back up the stairs.
Before I reached the top step I saw a light come on and heard someone close the door to the hall bathroom. I didn't think anything of it until I walked past my parents room again and I could still clearly hear the sound of box springs, someone bouncing up and down on the bed. And there was the distinct sound of voices moaning, one male and one female. That stopped me in my tracks. If my parents were still in their room, who was in the bathroom?
Maybe my sister had come back into town, but I hadn't seen her car when I came home, and I hadn't heard anything about anyone planning a visit. I looked over to the bathroom door and noticed a line of light around one edge of the door. It must not have closed all the way, and the air pressure cause it to spring back open a little. I tiptoed over to the door to try to see who was in there.
I pressed my eye to the crack but I couldn't see anything at first. After a minute I could just barely make out someone moving into and out of my field of vision. I heard the shower start up, and then someone came clear to sight.
An incredible naked body came into view, and my manhood sprang to life. Round hips and smooth legs cradling dark brown pubic hair and a clearly dripping wet snatch. My eyes moved up a taut stomach to a set of jiggling natural double D breasts, with just a little sag to them, and topped with wide areolas and long nipples. My gaze continued to travel up until I saw... My moms face, her hair falling down sexily around it. I froze for a minute, too stunned to do anything. My eyes wander back to her chest twice before I could stop them, then as the situation finally cleared my sleep shrouded mind I sprang up and sprinted back to my room to hide.
It was five minutes later, with me panting behind my bedroom door, when it occurred to me that my mom was the one getting into the shower, but I could still hear sex sounds coming from my parents room. The rational part of my brain finished connecting the dots and I sat down hard in front of my door.
Part of me said that whatever my parents were into was not only none of my business, but also something I didn't want to know in the first place. Unfortunately, after seeing my mom naked, all of my blood had relocated to my cock, so my rational thought processes weren't exactly in control at the moment.
Breathing heavily out of fear, I snook back down the hall to my parents bedroom. Apparently mom was being careless tonight, cause this door was ajar too. Weirdly convenient. I peeked through the crack and I could see my father almost immediately. He was naked on the bed, up on his knees fucking somebody I couldn't see very well doggy style. At this angle all I could see was him and a little bit of a girly ankle trailing behind him.
