I could feel Dierdre humping up and down, and I figured I must be getting some at least of the rhythm she was throwing onto her brother. I added some rhythm of my own, and poor Dierdre was getting it from bath ends. I only hoped David was shoving dick into mouth as cleverly as I was thrusting tongue into cunt.
"Suck it, Sis," I heard him groan, a heartfelt statement if I'd ever heard one. I started to hum against the puffy lips of her cunt, and juicy sweetness poured out onto my sucking month. I used my finger on her clit, felt it heat up, and there was even more of the Dierdre-cum to drink. I drank it.
She squashed down on my face, almost strangling me with the musky wetness of her pussy, and she was coming so fervently I didn't feel like pushing her off. I could breathe any time, but this was a pussy, and it was made for eating. So I kept on eating it, like the sex-greedy little pig I was.
Dierdre sidled off me, and I followed her as far as I could with my tongue and fingers. She was giving her brother enthusiastic head, as I could see now, on her knees, sucking his long pole with every muscle in her mouth. She could take him deeply, too. I saw her start at the tip and slide her mouth down slowly, until only his balls were showing, plumb against her little chin. Linda Lovelace, I thought, who said you were irreplaceable? I rolled up onto my side and watched with interest. Cock sucking wasn't one of my real talents, admittedly – I'd only done it a few times, never long enough to get a grasp of anything beyond the basics – but something told me this weekend might fill in the gaps in my sexual education. With a vengeance.
"Enough," he said finally, pushing her back. David was fully risen by now, his cock blood red and wet with drool and pointing at the sky. "Let me put it in you, Sis."
"Put it in me?" Dierdre mugged. "You just did it night before last. Don't you ever get enough? Surely your brilliant mind has told you by now that there are more important things in life than screwing, big brother." She stayed where she was, on her knees, looking up at him with a saucy twinkling in her eyes.
"Name one," David countered, dropping beside her. He slung one arm around Dierdre's shoulders and glued his mouth to her. They kissed loudly, passionately, and then he was settling onto his back and she was rising above him.
"He always wins that argument," she said to me, winking. She straddled him while he pointed his cock upward, aiming it for her pussy, and she began to come down slowly, misty-eyed and purring when the tip of his pecker bumped the splay of her open cunt. "Well, all right!" she said with a giggle plunging down swiftly. Her cunt opened, swallowed him, and she planted her pussy firmly upon his groin, mashing her soft, wet cunt lips against David's balls and pubis. Dierdre shivered, hugged herself, and began to sway atop David. He reached up, grabbed her jiggling tits, and his fingers were brutal but obviously satisfying as they pulled and tweaked her nipples.
I crawled closer, put a hand on Dierdre's abdomen. It was convulsing like earthquake ground cover, and her flesh was hot as fire. My hand slipped lower, into her thick, sopping wet bush, and I found her clit gave it at weak, ands he screamed "Aaaaiheebeee!" I did it again, and she started to hump up and down on her brother's prick, screwing him in and out of her drippy cooze.
My finger drifted lower still, and I felt the stiff bone of him, where he'd entered her cunt. I looked up at David. "This is a trip," I said. "I don't know what you two are all about, really, but I want to join."
"I thought you already had," he panted, thrusting up into his squirming sister. He took one hand away from her tits, twined his fingers among mine, and squeezed. His hand was warm and strong and comforting. If I'd found a sister in Dierdre, maybe I'd found a brother, too. David. "Stay loose," he added. "Let your desires be your guide."
"Okay!" I said happily. I looked at their faces, both of them intent upon the sex act, that concentration showing in the firm set at their mouths, the intensity of their green eyes, the little husky cries that occasionally, slipped through their teeth and lips. I studied them another moment, then decided how to get in on the act. I watched David's dick stabbing up into Dierdre, saw how her thick pussy lips spread outward when she was down on him, then seemed to pull up into her slot when she lifted high. I reached in, touching his cock and her pussy with the shy, inquisitive tips of my fingers, and I even managed to get one of my fingers into her alongside David's pecker. She was hot and slick in there, and I could feel tempestuous pulsating up and down the cunt slopped shaft of his tool. His heart was really pumping, and so was Dierdre's, to judge from the jiggling of her tits and the quiver of her shoulders.
"Mmmm don't stop either of you oh, damn damn, damn, don't stoppppppp!"
I wiggled my finger free and leaned in even closer. This was my very first time in a threesome, and I don't know where I got the idea, even, but I had it, and it seemed too clever to disregard. I put my arm around Dierdre's hips and glued my mouth to the battlefield.
She shrieked again when my tongue began to anoint her pussy while David fucked it, and she was a mess of hot flesh and sticky juices. He was a hard, thrusting shaft, and I licked him, too, tasting Dierdre's cream all over his penis. I couldn't do a lot for David, but I didn't need to he was doing okay by himself. The fast, rabbit-like stabs of his cock up her chute were frantic and energetic, as if he wanted to fuck himself to exhaustion before he gave up and squirted.
I got my tongue onto her clit, and there was no stopping Dierdre Banks. She abandoned the struggle and came in spasms, sinking don on David while I kept licking her clit and as much of her gash as I could get to. Wherever, she was awash in sweet fluids and I was cleaning her with my frisky tongue.
"Take it. Sis!" David moaned from low in his guts, and he quivered beneath her, thrusting up. Dierdre bounced on him, and she planted one hand on me, the other on his chest. She leaned forward, obviously frying to kiss him as they shared their come, and I think they made it, even with me in the way. I was being crushed between his stomach and hers, but I could not bring myself to move, especially when I began to taste David's hot cum flowing thickly from his sister's pussy.
He must have poured nearly as much into her as he'd squirted on my tits for me and Dierdre to lap up. It poured from the tip of his dick, into Dierdre's cunt, then rolled back down his shaft and out, collecting on the wet wiry hairs at the base of David's pecker. I drank it with my tongue as it flowed down and out, and there was plenty enough to drink! My tongue must have been white with the sticky, tasty jizz, and the salty, faintly metallic flavor was a treasure in my mouth.
"If you want it that badly," Dierdre giggled, on the other side of my head, and she raised herself, disengaging her pussy from David's cock. She moved to the side, and there was that sweet, red-raw pecker, its upper half still coated in creamy jizz. I grabbed it and stuffed it into my mouth, slurping and gurgling as I began to suck him dry, up and down the shaft, pushing him in until my throat ached from the pang of refusing him the deeper penetration Dierdre's gullet could offer. I sucked until he went soft and supple in my mouth, and still I kept sucking, reluctant to let him go so soon.
"Me, now," Dierdre called, tapping my head. I raised my eyes. She was lying beside David, her legs parted, her glistening, cum-drenched pussy on display. It was too pretty to resist! I spat out David's dick and clambered across him, hungry for his sister's cunt.
