Sexy Surprise

My older sister, .Jill, was home from her first year in college for the summer. I had just turned eighteen and was anticipating my freshman year in September. Her year away at school had changed her, she had lost her baby fat, grew her hair longer and dumped her old horn-rimmed glasses for contacts. I was embarrassed when I got a hardon looking at her when she bent over, but she really looked great and I blushed when she caught me.

Neither of us had been popular in high school, we didn’t play sports or participate in many activities. She was on the debate team and I was a computer nerd. Even in college, she didn’t do much except study, bringing home straight A’s much, to Mom’s delight. We lived alone with Mom in a secluded old farm house on the edge of town. We never knew our Dad because Mom divorced him when we were very young.

I noticed Jill had changed in other ways. She was showing more skin than ever before and was not afraid to flash her underwear, though I was sure it was an accident. Before college she would make sure everything was covered and would run complaining to Mom if I ever tried to peek while she was changing or anything. Of course, I always tried peeking, specially while she was using the bathroom. I used to take long soaks in the bathtub, hoping she would need to use the facilities. Our bathroom was set up so if I turned the full-length mirror just right I could see everything, even the toilet. Of course, Jill knew this, too, because when I used to try to spy on her when I was in the bath she would scream for Mom, I would get yelled at and the mirror would be turned so I couldn’t see. After a while she would just come in and turned it automatically when an emergency forced her to use the bathroom when I was soaking in the tub. Ever the optimist, I turned the mirror so I had a full view of the toilet, even though I knew Jill, who at 19 was a year older than me, would immediately turn it back. Maybe I could get a glimpse this time.

She knocked on the door. “Hey Brian I gotta go.” She shouted through the door. “I mean I have to pee right now.” Her desperation was obvious by her voice/

“Okay,” I yelled back, closing the shower curtain just enough for me to see the mirror.

She opened the door and came in but didn’t adjust the mirror. I was shocked to see her dressed in just a t-shirt and panties instead of her usual flannels. My cock got hard immediately. It stiffened even more when she pulled the t-shirt over her head and exposed her luscious tits. I had glimpsed her tits before, but bow I had a full view. They were perfect, not too big, but big enough so you could really enjoy playing with them. The nipples were perfect, too, and they got bigger when she started rubbing them. “Oooh.” The sigh of pleasure escaped her lips as she kept rubbing her tits and nipples. She reached down and put her hand inside her panties. She began to rub her pussy and moaned again as she rubbed. I was mesmerized by the sight of my sister frigging herself. My cock was hard as iron, but I was afraid if I touched it, it would break the spell. She started to pull her underpants down slowly. She stopped when they were just below her sparse pubic hair. She looked in the mirror and caught my eye, making sure I was looking. Then she smiled, turned around and let those pink panties fall to the floor, exposing her whole ass to me. She bent over slowly and stepped out of the panties.

She turned around and bent backwards, holding her pussy lips apart so I could see the pink interior of her pussy. It looked shiny and wet. She took one hand and put a finger right up her wet hole, fingered herself a little then brought the finger to her mouth and sucked all her cunt juice off. Then she put her hand back to her cunt and began to rub her clit.

“Unnh, it feels so good when I rub myself when I have to pee real bad.”

I could see the pink of her pussy and the wet juice that was running out of her hole. I didn’t move, didn’t speak, not wanting her to stop. Only my cock was moving, throbbing unmercifully. She continued rubbing her clit furiously. Suddenly she stiffened.

“Oh God, I’m cumming.” She gasped. ”It feels so good.”

I was staring at her cunt when suddenly a gush of piss spurted out of her cunt and on the floor.

“Oh God. I’m pissing and cumming. My cunt is exploding”

Another spurt of hot piss squirted out of her twat and splashed on the floor. She moved over the toilet and let her pee pour into the bowl and continued rubbing her clit. She finally sat on the bowl and caught her breath.

“It just feels so good when I play with my pussy when I have to pee.” She said breathlessly.

She stood up and threw a towel on the floor to wipe up the mess.

“I still gotta go, though.”

She stood over the bowl with her ass facing me, held her ass cheeks apart and started pissing. From this angle I could see the golden stream come right out of her pussy. When she was done she turned around, bent over backwards, held her cunt lips wide apart and let another spurt go right onto the towel. She shook her ass to get the last drops, then grabbed the towel and began very slowly and very sensually to wipe her pussy.

I was mesmerized by the show in front me, still not daring to move or speak, my cock throbbing painfully. I couldn’t believe what I was seeing. This my innocent sister who would scream every time I tried to see her naked. She threw the paper in the toilet, took the wet towel to throw in the laundry room and put her panties back on.

She reached for the doorknob and stopped.

“One more thing.” she said, pulling her panties down to below her ass cheeks. She held them open and let out a big noisy, smelly fart. She giggled, pulled her panties up and ran out of the bathroom.

I sat in the tub for a minute, still not believing what just happened, but my dick was so hard I had to do something. I got out of the tub cause I didn’t want to shoot my load in it. I planned to go into my room and jerk off to my heart’s content. All I needed was a pair of Jill’s panties. I slipped on the shorts that passed as pajamas and a t-shirt and headed for the laundry room. I began rummaging thru the hamper looking for a pair of Jill’s underpants when I was startled by Jill’s voice.

“Did you like my little show?” she asked as she snuck up behind me and put a hand on my ass.

I jumped. “You scared the shit out of me.” I said holding the used panties in one hand.

“Well, did you?” She was smiling, so I knew she wasn’t angry.

“I loved it, but I wish I could see it up close.” I blurted.

“You mean you want to look at my pussy and watch me pee up close?” she said, pretending embarrassment. “You might get wet.”

“I’ve always wanted to know how a girls’ thing works, so I really wouldn’t care.” I said, truthfully. “But why the big change? You always made sure I never saw anything, now you’re showing everything.”

“Well, you’re in your room jerking your cock and wonderin’ what a girl has between her legs and I’m in my room rubbing my pussy wondering what a real cock feels like so why can’t we get together?” she said as her hand found my cock. “My roommate talked about fucking her brother and it got me thinking. Wouldn’t it be better with someone you know and love than with some stranger? Now let me see it.”

Before I could react, she pulled my shorts right down exposing my throbbing hard on.

“I’ve never seen a real one before.” she whispered. She wrapped her fist around it and started measuring it. ”It’s so soft and yet so hard. It’s bigger than most things I’ve fucked myself with.” she purred. She started rubbing it up and down, fascinated by my prick. I never thought of it as big before, but I took her word for it. Her rubbing quickly brought me to the verge of cumming.

“Jill, I’m gonna shoot.” I said as quietly as possible and with that I started cumming, the thick globs of jism spurting onto her hand and leg.

“Yes, cum Bri, I wanna see you shoot your load.” She kept rubbing my prick until I stopped cumming. She put her hand to her mouth and licked up a wad of cum. “It tastes good” She exclaimed, surprised. She licked all of it off her hand. “That was great Bri. I would love to that again. But why are you in here? Looking for my panties again?” I was still a little afraid that she would tell Mom.
