I began rubbing the back of her legs as I used to do when we were growing up. They were smooth and in good shape. Obviously my sister still kept up with her walking and swimming as I had.
“So when’s Nadine coming home?” Carmen asked while still watching the movie.
“I think Mom said she would be here tomorrow or the next day.” I said while still rubbing her legs.
“Hmmmm, that feels good. Did you know Nadine had a crush on you when we were kids?” Carmen asked, arching her eyebrows as she looked sideways for me to see her facial expression.
“No way!” I said and playfully smacked her on the ass one time.
“Hmmmm. For real. Why do you think she has always been so shy around you?” Carmen asked closing her eyes for a moment after I smacked her ass and opening them when she made her comment.
“Nadine’s a lesbian. We all know that, even if dad was in denial. You and mom know that. We met a few of her girlfriends, remember?” I asked.
“Not exactly a lesbian. I would say bi. Sure she showed no interest in other men, but she loved her big brother. She used to blush whenever I mentioned you.” Carmen said.
“Oh really? You expect me to fall for this trick? I know you too well.” I said and pinched her inner thigh playfully.
“Ow!” Carmen acted like the gentle pinch was more serious and gave me another look of mock anger.
“I’m telling the truth, whether you believe me or not is up to you.” Carmen said as she returned her attention to the movie.
“Ok. Say I believe you. What does any of this mean?” I asked.
“Just trying to clue you in… big brother.” She said as she used her leg to rub against my growing erection.
“Ok.” I said and resumed my rubbing of the back of her legs.
“So, what were you really up to this morning, Mike?” She asked seductively.
“No… nothing.” I stammered.
“So you expect me to believe you were really taking a nude trip to the bathroom at night and weren’t up to anything?” Carmen asked.
“It’s the truth.” I lied.
“Mom looked a little… spent this morning. I wonder if she has a new lover.” Carmen mentioned and let the comment hang in the air.
“I really don’t know. That’s her business, don’t you think?” I asked.
“Yeah, it is her business. Just a big coincidence that she looked like she was making love all night and you were butt naked in the hallway.” Carmen said and stood up.
She took off her shorts revealing purple panties.
“I’m going to go take a nap. I didn’t get enough beauty sleep last night after the long drive home.” Carmen said and threw her shorts at me as she ran up the stairs laughing.
I tried to duck the shorts but they landed on my face. I wondered whether Carmen knew for sure what was going on between me and Mom, or if it was more of her usual teasing. I breathed her scent in from her shorts. The combination of her perfume and natural scent made my erection even harder as I laid on the couch much as she did.
I laid there thinking about my sister in her room. I knew she loved to sleep naked and wasn’t shy about it. She never locked a door either. As my erection grew, so did my curiosity. Eventually it became too much and I jumped off the couch and grabbed her shorts. I snuck up the stairs as quietly as possible.
I went to her room, which was next to mine. I dropped the shorts on the floor outside her room. I noticed her door was not shut all the way. I listened as I heard moans. I pushed on the door slightly until it opened about a foot silently. Thankfully, it was not like the home we grew up in where the doors would squeak. I saw Carmen on her bed with her back to me. Her legs were spread wide open and I could see her right hand working furiously on her pussy as she moaned. She never felt the need to be quiet with her masturbation sessions.
My hard cock pressed against my shorts and begged to be unleashed. I let it out and started rubbing it up and down. Even the night of sex with my mother had not done much to calm down my need for sex. I had gone three months without it and my sex drive was fairly good. I watched my naked sister playing with her pussy and occasionally take one of her own nipples into her mouth and suck on it wildly.
I heard her gasp loudly as she inserted three fingers in her pussy. I began matching the rhythm of rubbing my hard cock with the rhythm of her moans and thrusts of her fingers in and out of her pussy. Her tongue reached out and licked her lips in a 360 degree circle that showed how excited she was.
Her moans were loud and she did not attempt to quiet them, just like she never did while we grew up together. I watched in awe as she thrusts the three fingers all the way in and out of her soaking wet pussy. Her eyes fluttered and she was breathing loudly as she played with her pussy. I jerked my cock faster as her breathing picked up in pace, warning of her impending orgasm. Carmen was always a fast cummer and it was hard to keep up with her at times.
“Oh, yes!” She screamed out as her body convulsed and the clear liquid of her pussy juice shot out over the bed.
I shot my cum quietly into the handkerchief I had in my pocket. I ran to the bathroom and flushed it down the toilet and washed my hands before returning downstairs.
I flipped the channels of the TV, but could find nothing to distract myself. I worried Carmen would return downstairs after her orgasm, but apparently she meant it when she said she was going to take a nap. I felt quite tired myself after a night of hot sex with my mom. My eyes kept closing on me so I went upstairs to my room and collapsed on the bed in my current room.
I fell asleep. I dreamed of Marissa cheating on me with Tony and then my dream turned into fucking my mom in the pool. The dream got so steamy that I unconsciously decided to do it sometime for real. Then my dream turned to catching Carmen in the shower ala Psycho instead of a knife though I was naked and joined her. I fucked her doggy style as she leaned against the shower wall as the water washed over us both.
I woke as I heard a knock on the bedroom door.
“Supper time sleepy head!” Carmen shouted out laughing.
I turned over on the bed still half asleep and with the dream of fucking my sister Carmen still very fresh in my mind. I had to lay there unmoving until my hard-on shrank to normal size. I tried to think of anything nonsexual to get rid of the lust in my mind.
I rose from the bed in my wrinkled clothes. I smoothed them out as best as possible and stretched. I felt somewhat rested, but that was because I napped much longer than I originally intended to.
As I arrived in the dining room both my mom and sister were talking and eating their dinner. The sun was starting to set. “Where did the day go?” I thought to myself.
Mom and Carmen laughed as they saw me in wrinkled clothes. They rarely ever saw me like this. I stuck my tongue out at them. Carmen arched an eyebrow and mom winked at me when she saw Carmen wasn’t looking. I sat and ate the meal with a hunger I didn’t know I had.
“Careful or you might end up eating the table and “us” while you are at it.” Carmen said slyly.
Mom raised her eyebrows in shock and blushed. I shook my head and gulped down my drink.
“So what’s going on tonight?” I asked.
