Chapter 2: In the Bathroom
When I closed the door of my room, I dropped on my bed very tired after that hour of intense excitement with my sister. I closed my eyes trying to recover the picture of my sister's beautiful naked body. I couldn't believe what had happened between me and Cathy. I mean for God's sake, she's my older sister.
It's true I have had some sensuous thoughts about her before, which you can't help it if you see her dirty panties discarded in your bathroom's hamper carelessly or see her large boobs swinging under the loose shirts she wears everyday, but it never occurred to me I would feel this strong surge of desire and hunger to my own sister's body. And it never occurred to me I would have the courage to do what I did this night: smothering my face with her soiled panties in front of her, talking with her boldly about her private areas, forcing her to touch herself in front of me, asking her to expose her asshole and taste her dirty finger and worst of all ending it by filling her open pussy with my sticky cum. This last stupid action ruined everything between us and caused her to run furious to her room.
It was three O'clock at night. My parents had been back long ago. I couldn't sleep. I was so horny with the after image of my naked sister and I needed badly to relive myself. Then, I heard a soft knock on my door. I don't know why I felt the blood freezing inside my veins. My heart was squeezed with painful fear and helpless anticipation. Then, my door was pushed gently and she entered stealthily my room closing the door behind her.
I was mystified by her beauty when I saw her. Standing at the door with her feet inside her bathroom slippers, she was wearing a transparent grey slip which barely reaches her crotch. I could see very clearly her large brown nipples pressing against the flimsy material of her slip. The high hem of the slip revealed the bottom of a white nylon thong. Her sexy milky legs were going on forever.
"Dam it Tom. I couldn't sleep the whole night. And I just realized I didn't relive myself the way you did. "
"You mean you're not mad at me?"
"Of course, I'm mad at you. Do you think it would be ok when you cover my body with your sticky stuff? I spent one hour in bath trying to clean myself of that yaaaky thing. But, I felt cold and horny after shower. "
She reached the end of my bed and turned around to sit near my feet. She pulled the hem of her slip from behind to prevent her thong showing up while she's sitting. This caused the thin material of her grey slip to stretch over her bottom, showing the configuration of her lovely ass. I almost cummed inside my shorts when she sat down.
"Now, here's a deal Tom. I will allow you to watch me doing myself over one condition; you're not allowed to touch or smirch me with your sticky stuff. Deal? "
"Why do you need me then? I mean you can do masturbation by yourself the way you were doing it earlier?"
She blushed and gave me one of her killer looks;
"For some reason, your presence while I was enjoying myself made it much hotter for me. I was all wet and horny when you were staring at me in the living room."
"But I can't sit here and watch my sexy sister masturbate without relieving myself. I will cum all over myself and make a mess just watching you naked. "
I was playing a crazy game. My sister was offering to show herself again and I was asking for more than watching! Cathy bent her head thinking for a while when she stood up all of a sudden;
"You know what? I have a solution to this problem. Come with me."
"Where are you going?"
"Stop asking questions and follow me."
She opened my door quietly and turned her head to our parent's room. When she made sure that everything was safe and quite, she walked out very quietly. I don't need to say I followed her very excited and nervous at the same time. What would happen if one of our parents caught me with my huge erection following my older sister in her inappropriate outfit? I pushed these thoughts aside and started to wonder what's going on in the mind of this horny bitch.
Catherine pushed the door of our bathroom and called for me:
"Hurry up."
When I entered the bathroom, she locked the door. She switched on the light and turned to face me. The bathroom light was so bright and shining over my sister's beautiful body. Her brown large nipples were erect with excitement. Her tight slip was showing every curve of her hot body.
"Now, Tom. Take off you clothes and go inside the tub."
"Why do you need me inside the tub?" "Because I don't need you outside the tub, silly. I told you stop asking silly questions."
When she saw the puzzled look in my eyes she added:
"I need a sort of a barrier between us to feel safe. There, you can do what ever you want. Just, don't move outside the tub. Ok?"
"Sounds good to me."
I stripped off my shorts and moved inside the tub. My huge erection was pulsing in front of me. I leaned back on the cold wall of the bathroom and stood there shamelessly. Catherine gave me a satisfied smile. She undid the ribbons which were hanging the slip on her shoulders. Then, leaning forward to push the tight slip down, her large breasts were dangling in their magnificence. She struggled to free her ass from the slip causing her breasts to bob into each other.
When the slip reached her ankles, she stepped out of it and kicked it to the corner. Her skimpy thong was only a small triangle of nylon covering her private area and disappearing between her butts. The front panel was soaking wet with her juices. She reached up to her thong giving me her backside and hooked her fingers into the waist band. Slowly, she pulled down her thong, which was caught for a moment between her cheeks, to reappear suddenly with an elastic snap. She pushed her thong down her knees to her ankles. Stepping out of it, she picked it up with two fingers hesitantly and looked inside it with a disgusted face.
"I think this thong needs to be washed."
She moved to the hamper to toss it there when I cried:
"Can you give it to me? Please."
She shrugged her naked shoulders and handed her thong to me.
"I don't understand why guys are interested in girls' underwear!"
"Well, I don't know. Because they are sexy, private, warm, touching their forbidden holes? Because they smell like pussies?"
Cathy reached down to her pussy and started rubbing it.
