There was something incredibly hot about having sex with Mel, my girlfriend Michelle's sister, that made me think about practically nothing else until I did it again. Michelle was still my favorite, and I had no intention to let Mel take her place or anything, but I had never been able to stay focused on one girl as it was. Michelle not only knew that fact but had suggested I bang her sister in the first place (though alcohol may have played a role). In fact, Michelle was in the next room over that first time I banged Mel, no doubt able to hear everything. Even so, I felt that luck was too good to be true, so the next time I hooked up with Mel, Michelle was none the wiser.
I didn't want Michelle to think I was starting to favor her sister to her, so Mel and I agreed to keep it quiet this time. We both knew it was just a new, fun and brief infatuation that would pass, so we planned to simply ride it out. After I looked Mel up online, Mel and I met up less than two weeks after our first intercourse at the same location - her house - and didn't mince any words as soon as I arrived.
Words, actually, escaped me the second I stepped into that welcoming kitchen again. Mel didn't say a word either, simply standing in the doorway to the hall. I had thought Mel was hot the day I met her just a little while ago, but this time she had raised the bar, likely because this time we were meeting specifically for sex while the last time it had just kind of happened.
The 5'4" Italian babe smiled seductively at me, her bright brown eyes wide with excitement as her long, dark brown hair hung straight down to her shoulders. Plenty of her very tan skin was exposed as her thin, toned body was dressed in a short black miniskirt and a tight gray sleeveless top. Capping off the outfit were some pieces of jewelry and a pair of sexy black high heels which were backless and open-toe.
"My sister has talked a little bit about what you like," she said slyly as I very obviously took in the outfit. The next few moments were a blur, but we ended up in Mel's bedroom upstairs with the only clothing between the two of us that didn't end up on the floor being a bracelet, a necklace the shoes (all on Mel, of course), per my request. The next thing I knew, we were in the bed, Mel on her hands and knees, facing me as I knelt in front of her and watched her take my cock in her mouth.
"Shit, baby," I muttered as Mel bobbed her head back and forth, sucking as much of my cock as would fit in her mouth as she rubbed my balls, "you're so good at that."
Mel grinned, pulling back her head and stroking my cock with her hand just long enough to say, "Whose blowjobs are better, mine or Shell's? I won't tell." There was something fantastically dirty about comparing one sister to the other. I was more than happy to play along.
"I'd have to say yours," I said, probably being honest, though I may have just been caught up in the moment. "It's hard to say - I'll need a few more before I can really decide." Mel just grinned again and then went back to sucking my cock, this time sliding her head back and forth more quickly as she polished my knob. Her wet tongue pressed against the bottom of my cock while my shaft slid past those luscious lips over and over again, driving me wild and causing me to tilt my head back and moan. Meanwhile my hands traveled up Mel's sides, resting on her boobs for just a moment before grasping her hair and both sides and gently pulling.
Mel administered one of the most wonderful blowjobs I'd had in a while for another minute or so until she pulled back and helped push me onto my back, my cock now pointing straight up in the air while Mel shifted over me. With her knees straddled on each side of my waist, Mel took my cock in one hand, balancing herself with her other hand on my stomach, and guided my stiff erection, slick with Mel's spit, into her pussy.
Mel's sex hole was just as tight as I had remembered it, and, even though it was very wet from anticipation, it took a minute to push my thick cock all the way into the tight opening, making Mel and I even hornier as we were eager to start fucking. At last, Mel rocked herself all the way down to the base of my cock, the shaft now coated in Mel's vaginal secretions and ready to give my girlfriend's hot sister and I the fix we so desperately craved.
Still on her knees, Mel began to slide up and down me right away, both of us moaning right from the start. My hands ran up Mel's knees to her waist while the slender brunette rocked her hot body up and down, over and over again, her hair and boobs swinging as she fucked me steadily as I held onto her. I think my cock got even harder inside Mel as her tight twat clung desperately to my phallus that went deep into Mel each time she came down on me. Each time we made eye contact, we laughed a bit from the joy of the pleasure we were feeling as well as the naughty feeling of fornicating apart from Michelle's knowledge.
"Where does Shell think you are right now?" Mel said between breaths as she panted while sliding up and down me.
"A friend's house," I panted back.
"Well, that's not inaccurate," Mel said, pushing her hair out of her face and then putting her hand back on my waist. "I really don't think she'd mind if she knew what we were doing."
"Maybe," I said, and then we went back to focusing on sex. After another moment, Mel shifted back, picking her feet up and planting her high heels on either side of my waist, her knees now pointing up in the air and her hands behind her back, balancing herself with her hands on my legs. Now being able to view Mel's entire body from her toes to her head, I was wild with lust and sunk my nails into her flesh just as she went back to rocking up and down me.
Mel and I cursed in unison as she moved up and down, slapping her body against mine as she came down over and over again, hard and fast. Her hair and necklace swung around her neck, and her boobs jiggled up and down with the rhythm of her body's riding my cock until I reached up and squeezed her ample breasts, now holding them in place as she fucked me, coming down on my balls again and again.
