It was after three by the time we finished our Chinese feast and returned to our bedroom proclivities.
Christine kicked it off by dabbing at my balls with her hot, pink tongue. "She's gonna suck you so dry you won't get it up for a month," Amy chuckled.
In my mind I knew she was serious, but my maleness prodded me into replying inanely, "We'll see about that, little Miss Green Pants."
An allusion to Amy's preference for going to bed in a pair of lime green panties.
Fifteen minutes later, it was Amy with my cock in her mouth while her hands roamed over my ass and between my legs, probing at the base of my balls and the rim of my asshole. She was taking her time, in no hurry at all: Exquisite.
My wife, Christine was lying on her side, one leg nearly straight up in the air. The soft hair in her crotch formed a cushion almost back to her asshole. My face was buried in it, enjoying the pungent aroma of her previous orgasm. It was obvious that no guy's tongue had ever explored so deeply between her legs before, from the way she squirmed and the little sounds of startled pleasure she made. I nibbled at her clit, pushing its sheath back with my lips and sucking hard on the red protrusion the hood revealed. The muscles in her thighs fluttered.
We went round and round the circle like that for half an hour, all three of us rising to a fever pitch. Then out of the blue, Christine croaked, "Fuck her, Lucas! Fuck Amy!"
I nodded compliance and shook my sweat soaked head once or twice before moving up along Amy's sweat-streaked body and flicked my cock against the lips of her gaping cunt. She gasped and her lashes flickered. I eased her heels over my shoulders so her knees were up against her chest. Her athletic condition and small build gave her more flexibility than Christine could manage, and her pussy gaped wide. She hunched her hips upward, perhaps unconsciously, and I slid into her vibrating cunt. She moaned and the already snug tunnel squeezed my organ even tighter. I grasped her wrists and pinned them outstretched above her head. I felt her toes curl as her heels pressed down against my shoulders more firmly. My cock pushed against the end of her cunt at each stroke and she drew a sharp intake of breath each time, not of discomfort but because of the electricity passing between us.
I glanced down to watch my cock disappearing into that dark jungle and noticed her clit winking in time with my strokes.
"Do it hard, honey," my wife whispered in my ear. "She loves it hard!"
I began to slam into her with enough force to make her breasts bounce, but not enough to actually cause her pain. She wanted hard, I was giving her hard. Besides, I was enjoying it myself. I pulled her wrists a little straighter and her fingers writhed and curled into fists.
"Hook your ankles together behind my neck," I rasped, and she did. If I had had the opportunity to script this scene, I would have wound a telephone cord or something around Amy's ankles and tied her wrists to a couple of chair legs.
Now her eyes were closed and her head swung back and forth. She was even biting her lip. I leaned down and kissed the side of her throat, then moved up to the hollow space behind the hinge of her jaw. Then, as I thundered into my orgasm, I bit down slightly on her earlobe.
She jerked once, then again, and uttered a small cry. And then she was flooded by a paroxysm of a climax, her thighs jerking, her arm muscles spasming, as she came and came.
Finally, both of us ran down and I relieved the strain on her wrists. She let her feet fall to the floor and wrapped her arms loosely around my neck. All she could say between gasps was "Wow...."
I held my weight above her on my elbows but kept my cock in her for a few minutes. I pushed into her a short distance every fifteen or twenty seconds and her cunt jerked. She giggled at her own reaction and squirmed with delayed responses. This was something else I had learned from my wife β that a girl's cunt is very sensitive to aftershocks β and I was passing that knowledge on to her sister, who apparently had never experienced it before.
I slid the palms of my hands under her upper back and arched her ribcage upward so I could reach her nipples with my mouth. They were also hypersensitive now and when I sucked on each one for a minute or two, Amy moaned and hugged me tighter.
Finally, I began to develop a cramp in my upper arm and, regretfully, I withdrew my cock from her and rolled over onto my side. I studied her face in some fascination, my head propped up on the palm of my hand. Her eyes were half-closed, from physical exhaustion as much as sexual satiety, I thought. Her breathing was becoming regular again and there were beads of musky sweat drying on her body. Her pubic hair was stiff and spiky with escaped semen and red patches on her body showed the pressure of my weight on her.
Her knees were still bent and her legs parted. She looked rather like she had lost a wrestling match, except that the slightly dazed smile on her lips was happy and satisfied. My arms and legs were stiffening up and my cock felt worn to a stub. There was a mixture of semen and the cunt juices of two girls stiffening in my pubic hair as well. It had been quite an evening... but it wasn't over yet.
I looked around for Christine, but didn't see her. There were however, moans of a sexual nature coming from the master bath. Holding a finger to my lips, I signaled Amy that I was going after my wife.
She giggled happily and waved me off.
I paused and looked down at her lithe, firm nakedness, now displayed full-length. She stretched again, partly for my benefit, eyes closed and smiling. Very nice indeed.
I padded quietly to the entrance to the master bath and peeked inside. It was pretty obvious, from the rhythmic creaking of porcelain and the breathy gasping sounds, what was occurring inside. I opened the door and stepped in.
Christine had straddled the toilet and was facing the wall. Her right hand appeared to be buried in her cunt; her left was bracing her from falling off the porcelain bowl onto the tile floor.
With each thrust of her hand her breasts bounced and jiggled and her hair flew in all directions from her strenuous exertions. Christine looked over her shoulder and smiled at me for a moment but never changed her rhythm. I moved closer and squeezed both of her lovely tits. She smiled again. Then I felt a small, warm hand on my shoulder blade and another hand slid smoothly down my ass. Amy had joined us, standing on tiptoe to see her sister's masturbation. Moments later she rested her chin on my shoulder for a better view.
Christine held out her hand to her sister and drew her around from behind me. She moved Amy's hands to her breasts and encouraged her to squeeze and fondle them as I had done. Amy didn't hesitate, which surprised me a bit β though it probably shouldn't have by that time. In fact, she positioned herself so that I had access to her breasts and I promptly began rolling her still-prominent nipples between thumb and finger while nipping lightly at the back of her neck.
I sent my thumb back into Amy's ass, which was still sweaty and internally moist and my finger crept past her snug sphincter with little resistance. It was a sensation I've always had a taste for, though I was seldom able to indulge it with anyone except Christine.
Amy trembled a little and arched her back farther as my finger gradually slid in until the palm of my hand was flat against her buttocks. I wiggled my finger experimentally and Amy gasped in response.
"You like that?" I whispered behind her ear.
"Mmmm... yeah, I really do!"
Her hands continued to knead Christine's tits and my wife looked like she was building to an explosion.
"Kiss her, Amy," I whispered. "Kiss her deep, like you would a guy."
There was no hesitation by either girl: Amy lowered her face and Christine tilted hers upward. The joining of their lips was steady and prolonged, involving much activity by at least two tongues. I curled my buried forefinger and lifted a bit β a favorite maneuver that nearly always had the desired effect on the recipient βand Amy moaned passionately and clenched her ass muscles, squeezing my finger in a warm, wet, tight embrace.
Both girls came moments later. We decided that we'd call it a night and tumbled into bed without showering again.
Amy left the following afternoon, and Christine and I were quiet about the events of the previous night for several days. Then over steaks we grilled on the barbeque, we discussed what had happened. I assured her that I had no regrets and asked if she did.
"The incestuous part bothered me. It bothers me a lot."
"What incestuous part are you talking about?" I asked gently.
"What Amy and I did together."
"All I saw you do was kiss. How incestuous is that?"
"Is that all we did?"
"Well, aside from, say you putting my dick in her, or vice versa, I'm not sure as to who did what to whom, but, yeah, that's all. Oh, yeah, she rubbed your tits a little, but that's hardly incestuous."
"Really?"
"Yeah, really."
"I thought for sure I'd gone down on her."
