"Mom told me not to dress, just to stay naked. It's kinda' nice. Maybe you should try it," I replied.
"Not today," Becky replied, "Maybe some other time." Coming over to sit next to me on the couch, she asked, "Didn't you get enough of that last night?" Though I'd stopped stroking, my fist was still wrapped around my penis.
"Actually, I was thinking about you and your friends sitting on my face. That's what got me going," I replied, matter of factly. She stood up, pulled down her shorts and panties together and kicked them off.
"You mean like this?" she asked as she swiveled her hips around, showing off her neatly trimmed, dark brown bush. I hadn't noticed it the night before in the dim light but she had it trimmed into a perfect 'V' pointing the way to her pussy like a road sign arrow might point you toward an entry ramp. Staring at that, about two feet from my face, sent me right over the top. Feeling my testicles tighten and my penis begin to pulse, I shot two healthy ropes of splooge onto my lower chest followed by a couple of smaller spurts that landed on my abdomen and some final dribbles on my hand as I continued to stroke slowly. "Feel better?" Becky asked as I stood up to go into the bathroom to wipe myself off. When I returned to the den I found Becky lying naked on the couch, her shorts, shirt, and bra in a little heap on the floor. "If you liked eating us so much last night, maybe you'd like some more?" she asked. "Watching you beat off made me want it, too." As I went to sit down, she dropped one foot to the floor while draping her other leg up on the back of the couch. "You want to eat some more pussy, Joey?" she asked. Up off the seat of the couch, I kneeled down on the floor and Becky put both legs around my neck, a thigh on each shoulder as she swiveled her body to offer up that perfect 'V' marking her target to me. I looked up at her and saw a funny little grin on her face. Her tits, which took after Mom's, flattened on her chest, each sagging slightly toward its side of her rib cage, a large areola floating, jiggling in the middle of each mound topped by nipples standing at the alert. I was getting hard again already.
Diving into her neat little brown muff with my nose, I began searching with my tongue, finding her lips, licking each one from front to back. Becky moaned very softly, under her breath to herself and I drove on, probing between her lips with my tongue, deeper and deeper with each trip from front to back, back to front, until it reached as deeply as it could into her warm, wet pussy. Using the leverage of her thighs on my shoulders, she was beginning to thrust her hips into my face as I licked. Searching forward I found her clit, circling it with my tongue repeatedly before wrapping my lips around it to suck on it gently. It seemed to get harder, larger between my lips as I sucked it, tongued it. Now she was moaning but there was nothing soft or under her breath about her moans. She began to buck her hips, shoving her pussy into my mouth so hard repeatedly that I had difficulty keeping my lips on her clit. Shaking suddenly then stiffening, she moaned loudly and crashed through her orgasm. I stopped sucking and just continued to lick her pussy gently until she came to an end. "Oh damn, Joey." she said as she swung her legs off my shoulders and put her feet on the floor on either side of me. "Stick that damn dick of yours in me, now!" she demanded. I raised myself up on my knees to reach that wet entry and slipped my penis inside. Sliding in easily, I began to thrust slowly but she reached and grabbed my ass in both hands urging me faster. Harder, I hammered her as she pulled on my ass with each stroke, slamming me into her. I could feel my testicles slapping the front of the couch cushion beneath her ass with each pounding of my penis into her pussy.
Nearing my peak I groaned, "I'm gonna' cum."
"Do it, do it," was Becky's reply and I complied, rushing headlong into a sweet orgasm, plunging as far as I could into her, stopping there as felt my penis pulse, ejecting its full load deeply within my sister. Shaking and trembling as I did, I felt Becky cum again, her pussy alternately tightening and loosening its grip on my penis, feeling like it was milking me dry.
"Rebecca, Joseph. What the hell are you doing?" I heard Mom yell behind me as I finished my orgasm. Jumping, I stood up, my still mostly erect penis flopping out of Becky's cunt as I did.
Still lying back on the couch Becky calmly replied, "Nothing any different than what you and Joey were doing last night, I guess, Mom," with more than a hint of sarcasm in her voice. Looking at her I saw defiance in her eyes and my cum beginning to leak from her pussy. Mom simply turned on her heels and stomped up the steps. "She's just jealous she doesn't have her 'little boy' to herself," she told me as she got up off the couch and headed into the bathroom. Back from the bathroom, Becky picked up her clothes and walked out of the den and up the steps. As I stood in the bathroom, milking the last of the semen from my penis I heard their loud voices as Becky and Mom argued upstairs. Unfortunately, they weren't loud enough for me to understand what they were saying. As I went into my room and pulled on a pair of shorts, the yelling upstairs faded and I could no longer hear them at all. I went up and out onto the carport, sitting in a lawn chair and watching the clouds scudder across the late-morning summer sky, wondering where this all was headed now.
I sat there until Mom came to the door and called to me, "Joey, come on in for some lunch." I got up out of the chair and headed into the house. When I'd come into the kitchen, Mom looked down at my shorts and said, "I thought we agreed that you'd stay naked today."
"Oh, okay. I figured after before, you might have changed your mind about that," I told her.
