I froze up as a chill rode over my entire body. My mom had just walked in on me and my sister in the middle of an unbelievable orgy. I'd spent the evening pleasuring her lesbian friends, and showing them the way of the man meat. Unfortunately, my big finish was inside of my big sister, who was bent over the ottoman and taking every drop of my cum while my mom watched with a look of horror on her face.
"WHAT ARE YOU TWO DOING?!" she screamed in rage as the whole room froze. I was unsure about whether to withdraw from Bella's steaming cunt, somehow embarrassed that my mom would see my cock. I slowly slid myself out, now that I'd finished, and let Bella stand up.
"Mom, I..." Bella tried to come up with an explanation but choked on the words. Her 3 friends were already putting clothes on, understanding that this was clearly a family thing and that they had no place in the conversation.
"GET OUT," Mom cried as she pointed to the door, gesturing for our other sex toys to leave. I watched longingly as Lisa's beautiful ass, Valena's beautiful face, and Marie all shuffled out in a hurry. Tears started running down mom's face as me and Bella were throwing clothes on. "How could you do this? You're brother and sister!"
"No we're not, mom!" Bella said as she sat down on the couch. I made sure to sit down on a different one, for mom's sake. "We're strangers, we've only known each other for a couple of days!"
"That doesn't change anything," she said as she wiped the mascara streaks off of her face. "I don't care if you've known each other for hours or for years, you're still siblings!"
"But we're not REALLY," retorted Bella as if she was reading my mind. "Jim told me the story you gave him. You and Dad adopted us after you won the lottery! After you gave Jim away!"
I saw a flash of anger in my mother's eyes as she reacted to my sister's choice of words. "We didn't GIVE him away, you ungrateful little bitch." Bella jumped at my mom's tone, clearly caught off guard. "We couldn't support him. And when we had the means to have a child of our own, we did! WE HAD YOU!"
Now I was really confused. Mom blew her nose and sat down in a pile on the recliner, hopefully oblivious to the juices that were on it from Bella and Valena's facesitting session. "Your father and I wanted to have ONE kid of our own. You guys are ACTUALLY brother and sister..."
My jaw dropped as Bella and I looked at each other. The resemblance was suddenly striking: the toned frame, the dark hair and eyes. She shared my mother's strong features and enormous tits, compared to Vicky's petite blonde A-cup build.
"Jim," my mom said as her sobbing ran dry, "you're fucking your sister." I hardly wanted to correct her and tell her that I was fucking BOTH of my sisters, but this was clearly a more serious offense. A long awkward pause took place as my mom stared at Bella and thought of what to say. "Bel, I thought you were a lesbian!" My mom sounded indignant and disgusted, I didn't picture her as a bigot. Her angry facial features were starting to flare up as I realized how much of a bitch my mom might be.
"I was! I mean, I am...I don't know..." Bella looked at me for guidance, and I indicated that I wasn't offended. My mom breathed a sigh of relief as Bella continued, "I just hadn't found any guys that didn't gross me out. But I trust Jim...I don't feel like he's my brother but more of a family friend and I don't think he's a creep."
The tiniest smile crept across mom's face as Bella explained how I made her able to love a man. Mom dabbed the tears from the corners of her eyes and folded her hands gently in her lap. "Well this is just a terrible situation." She seemed upset, but much less so for some reason. "At the very least, you might stop running around with all of those crazy girls and doing all of those drugs and such."
Bella nodded vigorously, seeing an avenue. "I think it was just a phase mom, I just needed a push over the edge to see that some men have some good in them."
Now Barbara broke into a real smile. I felt like I was witnessing a breakthrough, and I got the impression that Bella's lesbian sexuality had driven a wedge between them. "What about you Jim?"
I felt uncomfortable in the spotlight now. I didn't have a wedge that I could pretend to lift and get my mom off my back. I knew Bella was bullshitting about not being a lesbian, based on the enthusiasm with which she tongued Valena's delicious snatch. But now it was my turn to show that this experience had bettered me, and I had nothing. "I just don't know anyone here..." my mom seemed unphased. "Bella and I realized we could help each other, and we had a connection, and it's all I have here, mom." I could tell I had played my cards right, with the "mom" at the end being a perfect touch.
"Well I'm glad that this was a growing experience for you both, but this can't continue." I don't know if she was referring to me fucking Bella, or the huge orgy we just had in our living room, but I didn't dare ask. "Why don't you kids go to your rooms." I raised an eyebrow until my mom clarified, "Separately! I'm going to be in to talk to you."
Me and Bella trudged back up the stairs while mom picked up the wine glasses and recomposed herself. "Mom will probably be up here in a minute," Bella whispered as we reached her door. "But no matter what she says, I don't want this to stop," she winked as she reached down and grabbed my dick through my sweatpants.
My cock sprang to life as I suddenly noticed how sexy she look with her disheveled hair and her perky tits outlined in her tanktop. I grinned and nodded as she bounded into her bedroom and gently closed the door behind her. I turned and went into my room, wondering how pissed mom was. I sat on my bed, trying to separate the thoughts of Bella bouncing on my dick from the thoughts of how awkward tonight was. Suddenly, I heard Bella's door open and close.
The voices were muted, but I was still able to make out parts of the conversation. Things began with whispering, but heated up as the argument got more intense.
"But he's your brother, Bella! Doesn't that mean anything to you?!"
"It means I can trust him, mom. It means we're connected, but it's not like I grew up with him or anything. It'd be like fucking a gay friend from college." I'm sure my mom was pissed at the casual reference to homosexuality, remembering she was a bit of a bigot.
"Fine. If you guys enjoy it and you're being safe, then that's fine, but no more disgusting parties in our living room!"
"That's fine mom, I'm sorry about that."
"And don't think I won't talk to Jim about this. If you two are going to keep up this 'arrangement' I need to make sure I can keep him honest, ok?"
"Sure thing mom."
