After sitting for a few minutes, I noticed I had already finished the whisky in my hands. I closed my eyes and leaned back, trying to figure out why I had this sadness. And I think I secretly knew the answer, which was jealousy. Not of Alena, or Kate, but of what they had together, a powerful love that was something I was contributing to but fundamentally not a part of. By getting involved like this I had left myself open and vulnerable, and I had gotten hurt.
It happens. Now I needed to decide what to do. Was I going to stop this? Pull back to just being a meat syringe and inseminating Alena? I didn't really think that would make me feel better.
Plus... my eyes closed, I saw Kate kneeling in front of me. Her ass slick with lube. I saw my cock pushing into it. I remember the feeling of being enveloped in my sister's ass. My cock started to swell as I sat there on the touch, and I started stroking it. In my head I imagined Kate looking back at me, pushing herself onto me, and I imagined her reaching down and rubbing her clit while I fucked her ass. Her breasts swaying as we fucked, her nipples grazing against the bed. I wanted her to pull me out of her ass, roll the condom off of me, and guide my cock into her pussy. I wanted to feel my sister all around me.
I heard a rustle in the room, but pretended I didn't. I was enjoying this too much. I kept my eyes closed, and kept stroking my cock. The couch sank next to me as someone sat there, and I felt a hand on my thigh. I stroked harder. The weight shifted, and the hands parted my thighs -- someone was kneeling beside me. I felt a hand clutch my balls, then stroke the base of my cock. My head spun, the whiskey hitting me. I felt breath on the underside of my cock, and an arm gently moving my hand off of my cock. I felt a lick up my shaft, before feeling a warm wet mouth take my cock. A tongue swirled around the head.
"Oh, Kate," I moaned, "yes! That feels so good."
I heard a muffled moan as the mouth on my cock moaned in pleasure. I heard the wet sound of a pussy being rubbed between my legs, and felt little twitches through my cock as she pleasured herself. I went to stroke her head and touch her as she sucked my cock, but my hand was intercepted and pushed to my side. I complied. This blow job was amazing. My head swam.
"Kate, I'm getting close..." I warned her. The blowjob stopped, and a body eagerly straddled me. A hand grasped my cock and I felt my head positioned on a very wet slit.
"You've always wanted this, haven't you little brother?" but, the voice was wrong. It was Alena's. I reached out and grabbed her hips, thrusting her down onto me, keeping my eyes shut tight. Imagining Kate's wet pussy swallowing my dick. Imagining her hanging boobs bouncing in front of my face as she bucked on me.
"Yes, Kate, I've wanted to fuck you for so long..." I moaned, clutching her body to me. Convincing my mind there were curves instead of skin taught over lithe muscle. "Kate, I love you!" I moaned, grinding my cock faster.
"Are you going to breed me, little brother?" the voice whispered, "are you going to fill my unprotected pussy with your seed? Or can you pull out?"
"I... can't..." I moaned. "I can't pull out of you. I need this. I need you."
With this she moaned hard and started bucking on me, her pussy wet against my balls, her clit dragging against me with each move of her hips, pulling my dick as deep as it would go.
"Kate," I breathed, "you're going to make me cum, you're going to make me cum!"
"Yes!" the voice growled, and I felt lips on my lips, kissing me passionately, a tongue pressing into my mouth. "Cum in your sister! Fill me with your seed! Fuck, fuck!"
She started trembling as the orgasm took her, and she latched onto me like a crab, pulling me so deep inside of her. I imagined Kate's breasts pressed against my face. My cock lost all control, spurting cum, pleasure overwhelming me. I threw my head back and moaned my sister's name.
As the twitches of my cock slowed, each one bringing about a spasm from the body clinging to me, I opened my eyes, finally. The lights had been turned off when I had my eyes closed, but I could still see the silhouette of my sister, standing in the doorway. Her expression was unreadable. She moved over, her hips swaying, and grabbed a blanket, draping it over both of us, tucking it around my back as Alena still clung to me. I went to shift out of Alena, but Kate stopped me.
"Best stay in that position for a while," Kate murmured, "you keep her plugged is probably all that's keeping the cum in her." Kate leaned over and stroked my hair once, then kissed me on the cheek, before she leaned over, and kissed Alena the same way. "I'll keep an eye on the clock and come get you two when it's time," she said, stepping out of the room.
Alena didn't move, or say anything. Her breath slowly got slower and shallower, and her head drooped onto my shoulders. Her muscles relaxed, and I had to hold her up. I think she was falling asleep. My cock slowly got softer inside of her, but each movement still sent a thrill of pleasure up my body.
What the hell was that? Alena, the consummate lesbian, had blown me? Had ridden me, asking me to call her my sister's name? And had seemed to get off on it? Kate was so loving afterwards, but I can't tell how she felt about it. She saw -- she saw the desperation I had developed for her.
I didn't have the energy, emotional or physical, to sort this out right now. But I didn't feel sad anymore. I felt good. I felt fulfilled.
After a little bit of time, Kate returned, dressed in a robe and carrying a cup of tea. She held up a hand gesturing at me not to move. And came and sat next to me on the couch. I raised an inquisitive eyebrow, gesturing at Alena, completely passed out with my cock still inside of her.
"Yeah, sorry about that..." Kate whispered, with a slight grin. "Remember how we talked about you filling Alena up in her sleep? Well, to that end, she took a sleeping pill... some sleeping pills... and they really put her out. As you can see."
