Not enough

"Is this what you want?" I asked, presenting my clearly outlined boobs for him to get a good look at.

"What? What?" was all he said as I tweaked my nipples, arching my back to pull my dress even tighter against them.

He made no move to either clean or take hold of my boobs. "I guess this isn't enough," I said, effecting a pout. "Nothing you haven't seen before. Fine, you win," I added, after all it's not like he hadn't seem my boobs in a tight outfit before. Just preening for him wasn't enough to get his lazy ass up. I pulled my arms through the shoulder straps on my dress and pulled it down, giving him a view of my braless tits.

"Better?" I asked, cupping them and presenting them to him again, hoping this would be enough to get him moving.

"What the hell are you doing?" he asked, almost sounding panicked for some reason, although his eyes were locked onto my breasts as I played with them.

"Fuck, still not... Well, I guess you have seen these before too," I replied pensively, upping my self play hoping he would change his mind. He just kept looking at me as if frozen. Well, if seeing my tits wasn't enough for him, there wasn't any point to showing him my pussy; he's definitely caught a glimpse of that during some bathroom accidents too. I kept sexily running my hands over myself for a second as I tried to think of what he might want. Of course his dick was hard and tenting his pants, so it wasn't complete lack of interest... If my hands hadn't been busy, I might have facepalmed, it was so obvious.

"Oh, of course that's it," I said, my hands leaving my own tits and leaping to his pants. I had the zipper and his underwear down in a second and his hard dick stood up, rhythmically pulsing. 'Wow Bro, nice dick,' I thought, though I refused to give him the pleasure of hearing me say that out loud; I had to maintain some level of mystique. I took it in my hands and began to jerk him off.

"What the... Amy what are you FUCK doing?!?!" he yelled, jerking away from me, though not enough to completely dislodge my grip on his member.

"Fuck, STILL not what you wanted?" I asked, a bit annoyed. I twiddled his dick, appreciating the firmness, his crown poking above my hands. I mean, sure it was obvious, but I had still been hoping to get away with just this much. "Fine, fine, I'll do it, ok?" I said, leaning over further and licking his glans. He almost seemed like he was pulling away from me, but it must have just been the shock of contact. I kept a firm grip on his pole, made an O with my mouth and popped his crown inside.

"AMY!!" he cried, thrusting more of his length into my mouth.

'Not bad,' I thought, plunging my mouth onto his hard dick, savoring my brothers hardness and taste. 'I guess if I have to do this, at least my little bro has a good dick for it," I thought as I thrust up and down on him. His hands, which had been gripping the couch, came up as if to pull my head off him, which made no sense, but then I plunged down as far as I could and he spasmodically pushed me onto his pole harder, as expected, though I prevented him from turning this into a deep throat. I didn't need him to get off his ass that much. I began rapidly moving up an down, being sure to groan sexily and letting him hear the wet gluck of his meat hammer hitting the back of my mouth. I felt him tense, his hips thrusting up at me, and pulled back, jerking his dick as I made sure to point him at my tits. I effected moaning sexily (not entirely faking it) as he shot his jism over my body, mostly getting it on my tits, but a few stray shot landing on my face or my rolled down dress.

"Oh my god sis," he gasped, breathing hard as he relaxed from the orgasm.

"We good now?" I asked, being sure to make it sound sexy rather than impatient as I wiped his spunk off my breasts and made a show of slowly licking it off my fingers, pretending to (and actually) savoring the taste.
