Like every other guy in the world, I wake up with a terrific hardon every morning. When I wake up, I always have to piss like a racehorse. But usually my sister Andrea is in the bathroom, taking a long shower, doing her hair — you know, the whole ball of wax.

Well, one morning, I had to piss really badly. The bathroom door was closed, and the shower was running. I tapped on the door, and opened it a crack.

“Andi, I gotta pee,” I said through the door.

“Well, I’m in the shower,” she said.

“Then hurry up, I gotta pee!”

“Go downstairs to Mom’s bathroom,” she said.

“Yeah, thanks,” I said and started to walk away.

Andrea finally took pity on me and said, “Well, come on in then and pee, I promise I won’t look, if you don’t.”

I pushed the door open and stood there. I could see her naked form behind the frosted glass shower door. I walked over to the toilet and moved her lacy bra and panties and lifted the lid. Pulling my still slightly hard cock out of my shorts I started peeing. I glanced to my right, and there was my sister moving behind the glass doors. I could make out her nipples and her dark patch of pubic hair through the glass. It was a sight to behold. I finished peeing, and looked once more as I shook the few drops of piss out of my dick.

To my surprise Andrea must have been able to see through he frosted shower doors, because she said, “If you shake it more than five times, you’re playing with it.”

“I’ll leave that up to you,” I said back, trying to sound like I was teasing her. “Come shake it all you want.”

“You’d better get out of here before I take you up on that,” she answered.

Jokingly, I tugged at the shower door. It slid open, and my sister stood there, totally naked. She stared wide-eyed at my cock sticking out of my shorts, and I stared at her round, firm tits and her snatch. I could feel my cock begin to grow again.

“Well, take off those damned shorts and get in here,” she said, her voice sounding slightly shaky.

Was this a dream come true? I’d never been naked with a girl before, and hell, even if it was my sister, Andi was a good-looking female. And she was going to let me be naked with her!

I didn’t need a second invitation. I peeled off my shorts and left them there on the floor and stepped into the shower with my sister.

Andrea spun me around and started to wash my back with the bar of soap and her soft wet hands, lingering on my buttocks. My cock was sticking straight up in the air by now, throbbing, needing attention.

I turned toward her, my swollen cock swinging around and poking her in the thigh. My sister looked down at it, her eyes widening. “That’s quite a big one you’ve got there, Tommy,” she said.

My adrenaline started pumping as my beautiful sister knelt down in front of me. I wasn’t sure what she was going to do, but when she put her soapy hands on my cock and started to wash it sensually, I just about fainted.

Just as I was about to reach down and grab her tits, I was startled by the sensation of her mouth surround- ing the head of my hard cock. And then to my surprise and delight she plunged her mouth all the way down on my cock.

Her tongue working fast and furiously on the head of my dick, she reached up and began to massage my balls with one hand while the other stroked me into her mouth.

I was going to cum really soon, and I didn’t want to but Andrea was blowing more than my dick. But I was determined to draw this experience out for as long as possible so I pulled my cock out of her mouth with an audible popping sound. I backed away, reaching down and pulling her to a standing position.

“Sit down,” I said.

She sat on the built in shower stall seat. I got on my knees as she spread her legs, and I let my tongue move up her thighs to her snatch.

Her pussy was covered with soft downy brown hair. I licked it, up one side and down the other, and then I reached with both hands and pulled her pussy lips apart. I was so worked up that I could feel my pre-cum leaking out and smearing into my own pubic hair. Without hesitation I licked her inner labia, and then stuck my tongue into her hot moist cunt, then moving my tongue in and out her frantically as her legs began to shake. Then I moved it up to touch her clit.

She jerked as I touched her it. I knew that much about the female body, and I continued my assault upon that bright pink little nub. She moaned and groaned loudly, telling me how great it was as she came in my mouth.

After a moment or two to allow her to recover, I stood up and with the water was cascading down on my back I moved my cock right in her face. She leaned forward and took my dick into her mouth once more.

She reached up and began stroking my cock in time with her bobbing head movements, and with the other hand, she reached around behind me and moved her thumb gently toward my ass hole. She sucked harder and faster, and soon, I could feel my own orgasm coming on.

I had no idea if she wanted me to cum in her mouth, so I pulled out. Backing away, with her hand still on my cock. Andrea kept stroking me, pointing my cock at her open mouth.

My cum flew through the air as my dick suddenly swelled and jerked. The first few gushes landed on her tongue, then her chin and neck. She swallowed my sticky white cum in the most lewd fashion, almost like one of those porn stars you see on videos.

Andrea continued stroking me, letting the last few drops fall on her tits.

Afterwards we got out of the shower and dried each other off, and then we both ran down the hall to our separate rooms, naked, and put on some clothes. We didn’t want our parents to catch us.

Now a days I don’t have to worry about bathroom privileges, if my sister Andrea is hogging the bathroom, I know what to do…

The end
