Jo was standing in my open doorway, leaning casually against the jamb. She raised her hands and started to clap. The noise startled Katie who bolted upright.
"That was absolutely both the last thing I ever expected to see and the hottest." Jo said as she came in and sat in my chair. "So what happened? Did Patty dump you?"
Katie sighed. "No, well we had a big fight and I dumped her."
"And Mikey was here to pick up the pieces..."
"No! It wasn't like that. Well, sort of. We've been talking all evening and finally I asked him to fuck me. I really, really needed it."
"Must've been one hell of a conversation..." Jo said smiling.
Katie grinned, "Yeah it was." and she reached out and patted my leg. "Thanks Mikey, that was great. You're gonna be a great lover..."
"Gonna be?" Jo asked. "He looked pretty damn good to me. How long have you guys been fucking?"
I looked at the clock on my computer, eight twenty six. "A little less than an hour."
"Fuck! No way!"
"Hey what are you doing home so early?" Katie asked.
"Oh it was ridiculous. The boss got handsy and suggested we go in the office for some one on one counselling. I quit. Actually I stood on the floor in my zone and yelled that if he ever groped me again I would sue the place, then stormed out."
"Wow..." I muttered.
We sat there in silence for a minute before Jo spoke again.
"So let me ask you both a couple of questions. Are you going to fuck often?"
"I hope so." I said.
"Yeah, I hope so too..."said Katie.
"Good, good. Okay then, if you're going to fuck some more, can I watch?"
"What?" We both said.
"Well it was so damn hot! I mean brother fucks sister... Shit, incest stories are my favorite erotica. I never dreamed it might happen in my own home. I'd love to watch you guys while I masturbate!"
"I can't believe this..." I mumbled.
"Me neither." said Katie. "I dunno... I mean, yeah it's weird but kinda erotic too. But..."
"Well there's another question you need to think about." Jo added. "How are you guys going to keep this from Mom?"
Katie and I looked at each other.
"My silence and cooperation could be bought... or I could become a co-conspirator and accomplice..."
"Wait..." Katie said, "You want to fuck him too?"
"Actually I want to fuck both of you."
Katie's jaw hung open and my brain froze.
"Okay I know what you're going to say. I'm too young. Hell you and Mom both lost your virginity younger than me. And although I've not had a cock, I have had a pelvic so I have no hymen. I have made out with a couple of girls before and liked it, but we didn't get very far. And that pelvic? It was about a month ago and it was to insert my IUD, so I'm safe. And lastly, this: I would rather keep sex in the family, nice and safe than with some guy I don't know as well. So what do you say?"
Katie looked at me. "Well? You know I want her. How about you? Do you want to fuck your little sister?"
"You're damn right I do!"
Jo grinned. "It's a deal!"
Jo stood up smiling. She was wearing typical waiter attire, black shirt, slacks and shoes. She kicked off her shoes and then dropped her pants and kicked them off and aside.
"I am never wearing this shirt again!" she said and ripped it open. Buttons flew everywhere. She flung it down and her sports bra followed. As I looked her over my cock began to swell.
Jo was slim and very fit.I watched as she removed her panties and then stood with her hands on her hips. Her breasts were so incredibly erect with no sag at all, but what surprised me was her huge puffy areola and erect nipples. Each nipple was pierced by a silver barbell. Her navel was pierced by a curved ring and her pussy was completely bare.
"What?" she asked.
"Oh nothing, just surprised at how much you've grown up, and how sexy you look." I stood up and took her in my arms and kissed her. Soon Katie was there with us, wrapping her arms around us both. We traded kisses all around. The sight of my two sisters kissing was so erotic that my cock was rigid in no time.
"God Katie, do you know how many nights I've dreamed of kissing you, of feeling your mouth on my pussy?' Jo asked.
"Damn, and I just told Mikey that I wished I could teach you..."
"I want you to, I really do. But first I want to watch Mikey fuck your pussy."
"We can do both." Katie said and went over and lay on my bed. "Come fuck me Mikey."
I mounted Katie and slid my cock into her still wet and oozing hole. Then I started thrusting slowly in and out as she moaned and cooed. Jo sat next to us and watched for a few minutes.
"I can't see, sit up Mikey."
I sat up and pulled Katie close. She spread her legs and Jo leaned in close.
"God it's so beautiful." she said softly. "I love the way his cock is soaked with your wetness." She inhaled deeply. "I love the smell too!"
She reached out and began to gently toy with us as we screwed. Her fingertips first teased my cock and then Katie's clit causing her to yelp in excitement.
"Jo, come sit on my face." Katie said and quickly our little sister moved up to the head of the bed. At first she sat with her back to me and held onto the headboard. After a few minutes she turned around and sat facing me. I reached out and began playing with her tits. It was a little weird to play with the barbells through her nipples but she apparently liked it and encouraged me. I leaned down and kissed them, then flicked the jewelry with my tongue. Jo giggled and hummed her pleasure. She ran her fingers through my hair and I felt an electric tingle run through me.
Katie must've been pretty good because soon Jo had her eyes closed and was swaying and moaning. I started kissing her. Jo's tongue darted into my mouth and her kisses became more impassioned and hungry. I felt her right hand on my cock and then she made a ring with her finger and thumb, squeezing my cock as I fucked Katie. With her left hand Jo was masturbatiing Katie's clit. Jo came first, screaming her ecstasy into my mouth. Katie followed a few minutes later, her cries muffled by Jo's grinding pussy. All of this excitement and stimulation pushed me over the edge and I knew my own orgasm was just strokes away. I pushed Jo back and pulled my cock out of Katie's drenched pussy. A couple of strokes and I was cumming. I squeezed the tip and sprayed my load all over my sisters. Thick ropes of cum splattered Jo's tits, chest and tummy. Gobs dripped and streams of cum ran down onto Katie's massive breasts and pooled in the valley between them.
"Oh god!" Jo cried in surprise. "Shit, that's a lot of cum!"
I squeezed out the last drops and sagged over to the side, breathing hard. Jo leaned down and kissed Katie's mound, then her pussy. Soon they were lost in a private world of lesbian pleasure. Watching my sisters go 69 was of course hot. But the knowledge that I had just fucked one and the sight of my cum oozing out from between them and running down Katie's side was wild. I realized that what they were doing, we, were doing was wrong. It was incest. A really big social taboo. But hell, so what? Who were we hurting? It wasn't like I was going to get either of them pregnant. And we certainly weren't going to advertise. Shit, no this was going to be a huge secret. One we would keep for the rest of our lives.
Soon the girls were no longer eating each other, but simply lying there, tired and blissful. Jo had slid forward enough to lay her head on Katie's thigh. Now she slowly rolled off to the side. She looked up at me and smiled.
"Did you enjoy the show?"
I grinned. "Hell yeah."
Katie sat up, "I need to pee..." she said as she stumbled off to the bathroom.
I looked back at Jo. "So, how was it?"
"Nice, really nice. I have wanted her for so long. It was my fantasy for years, that she would take me and teach me. Hell I never expected it to happen. And I never dreamed that my first guy would be you."
"It doesn't have to be. You can wait you know."
"Why? Don't you want me?" Jo asked. Then looking in the direction of the bathroom she sighed. "Oh, I get it. You prefer big tits."
"Wait, yes, I love full figured women. But I don't have enough experience to judge. Hell Jo, I fumbled my only other attempt to lose my virginity. Katie was really my first and this is all happening too fast. Am I excited by her breasts? Hell yeah. Do I get excited looking at you? Yes, yes I do. I just never thought about making love to you before because, well, you're my baby sister and I knew it was wrong. But after all of this... Well I am excited that you want me. And I want you. But I understand if you change your mind."
Katie had come out of the bathroom and sat in my chair.
"He's right. We don't have to do this. But I gotta say I really, really want to. This feels so good, so right. I love you guys with all of my heart, now I can show that love in the most intimate of ways. And I am very happy right now. Happy in my heart."
Jo and Katie stood and hugged each other tightly.
