Before Mom left, she stopped, came back to the kitchen, and said, "Don't do anything you're ashamed of."
Mom turned around and walked away, leaving my sister and me shocked.
Sue and I got up from the table, moved together, and shook our heads.
"What the hell did she mean?" I said while staring at the door Mom just exited through.
"I'm not sure, but it sounds like Mom and Uncle Bob fooled around," Sue said.
"Mom said we weren't the first siblings to fool around. Maybe she didn't get pissed at us because she did the same things with her brother."
Sue put her arms around my waist, pulled me close, and kissed me. "Did or does? It's only two hours from here to Portland. Maybe they're still getting it on." Sue chuckled. "As Mom said, she doesn't tell us everything."
"So, what should we do now?"
Sue grinned, pulled her top off, then sat at the table. "We should finish our breakfast, take care of the dishes, and go to my room."
Laughing, I took my seat and looked at my topless sister. "How can you think of sex after what Mom said?"
Sue finished chewing her food, swallowed, and took a sip of coffee. "Jim, since we made love the first time, I haven't thought about much else. I don't know about you, but I love sex. It's as if a dam burst and released all my pent-up desires. All of my hidden fantasies are becoming a reality."
Sister or not, this was a dream come true. I felt much the same way Sue did regarding desires and fantasies and wanted to continue our discovery. As I thought about my response, I watched Sue's chest, smiling as her full breasts jiggled when she moved. I felt my cock twitch and swell as I thought about the first time we fucked.
I smiled. "You're right about thinking about sex. Since making love, it's consumed my thoughts too. I was worried you wouldn't want to continue because Mom knows."
Sue got up, came over to me, sat on my lap, and hugged me. "Nothing could be further from the truth. I want to continue what we're doing and more. You have no idea how it makes me feel when you look at me like you do. Didn't Mom say there was nothing she could do if we wanted to have sex?"
"Yes, she did, Sue." I put a hand on one of her breasts. "I look at you like I do because my sister is so sexy. Not to mention the fact you have great tits." I massaged her firm mound.
"My boobs are all yours, along with the rest of me." Sue kissed me. "I wonder how Mom will take it when she discovers we're sleeping together?"
"I don't know whether sleeping together is a good idea. Not until we find out how she really feels about us having sex. Until then, we have all day."
Sue slipped her hand into my pants. "Okay. Let's make the most of the time we have together."
Sue and I finished eating, cleaned the kitchen, and went to her room. We hugged, kissed, and removed each other's clothing. Naked, we got into bed and rubbed our bodies together. Sue wiggled against me as she slid down until she could get my cock in her mouth. As she bobbed her head, taking more into her mouth each time, I rubbed her head.
"Turn around so I can do you."
Keeping my cock in her mouth, Sue nodded, shifted on the bed, then lowered her crotch to my face. I gripped her ass, pulling her down as I licked her tangy sex. We used our mouths and hands to excite each other. When I put two fingers into my sister's pussy, she moaned, reached between my legs, and caressed my balls.
It didn't take long before I felt Sue's legs quiver and her pussy contract around my fingers. I flicked my tongue against her clit as she came, and her juices coated my chin. As she rocked her hips, rubbing her pussy on my face, I came, shooting cum into Sue's mouth.
My sister and I remained with our faces in each other's crotches as we recovered. I ran my hand over her back and ass while she rubbed my balls. We rested for a few minutes, then Sue took my semi-flaccid cock into her mouth and sucked me. When my dick grew, she started bobbing her head, making me hard again.
Once I was firm enough, Sue moved down my body, gripped my cock, and lowered herself on my hardon reverse cowgirl. I watched her ass as she bounced up and down, impaling herself on my cock. Sue put her hands on my legs and rotated her hips as she fucked me. I ran my hands over her ass, moved my hands to her hips, and held her while driving up into her.
After a few minutes of my steady thrusting, Sue disengaged, got onto her hand and knees, and wiggled her ass. "See anything you like?"
I knelt behind my sister, grabbed her hips, and pushed my cock into her pussy. "You're damn right I do."
Gripping her hips, I slammed into her, causing my hips to hit her ass, making a slapping sound. Sue lowered her shoulders to the bed, diddled her clit, and rocked her body, meeting my thrusts.
"This feels so good. Fuck me hard, Jim. I love it," Sue shouted.
"You're pussy is so hot. I want to fuck you forever."
"My body's yours. Take me any way you want to."
Sue and I kept it up for another ten minutes before I pulled out of her pussy, flipped her on her back, and moved between my sister's legs. She pressed heels into my ass as I shoved my cock back into her. I pumped for a few moments, stopped, and dropped my head, kissing her as she wrapped her arms around my neck, holding me tight while stabbing her tongue into my mouth.
Returning her hand to her crotch, Sue rubbed her clit and begged me to fuck her harder. I gazed down, watching her breasts oscillate as I pounded her.
"Don't stop! I'm going to come," Sue shouted.
"So am I."
A few minutes later, Sue came, and so did I. I shoved into her as my cock surged, sending several spurts of semen into her pussy. She writhed beneath me, moaning as her pussy spasmed around my cock. I remained still, relishing the feeling of my sister's pussy quivering around my dick.
Sue held me and kissed my neck. "Wow! It gets better each time we make love. You lasted a long time."
"I guess getting a blowjob first helps."
Chuckling, Sue wiggled. "It helps me. I love sucking your cock."
We remained connected until my cock softened and slipped out of her pussy. I got up, scooped my sister into my arms, and carried her to the bathroom. She held me around my neck while I turned on the water and stepped into the tub. I let Sue down slowly, holding her as her feet hit the floor. We hugged, then I took the soap to wash her. When I finished, my sister washed me.
Sue rubbed my genitals with her soapy hands, looked into my eyes, and smiled. "So, how long before this big fella gets hard enough to fuck me again?"
"It's going to take a while. You drained me."
"How many times can you come in a day? I can get off a bunch of times."
"Really? How many?"
"I don't know. I think I've come five or six times with my dildo and fingers. It's way better when you eat and fuck me."
