The next day I was an awkward mess. I didn't know how to act around her. I would stare at her until she looked at me, then I'd look away. I could barely look into her eyes when she talked to me. Before we both went to work, she forced me to talk to her.
"Look, Mike," she said, getting right to the point. "It was just some fun and you need to stop acting all strange. If we're going to do it again, you need to stop weirding out about it, OK? See ya later!"
I watched her leave and all I could concentrate on was her saying 'if we're going to do it again...' Hell yeah, I'd force myself to stop freaking out if it meant she'd let me jerk off to her tits again!
That was perhaps the longest shift I'd ever worked. I wanted the day over so I could get home. I could barely eat on my break; my stomach was churning with excitement. Would anything happen tonight? Would she maybe let me touch her? Holy fuck I was excited. Then as I always do, I had to let negative thoughts sneak in there too. What if during the day at work she changed her mind and decided once was enough? Or even if we had a chance to do it again, what would happen when Mom and Dad got home the next day? That'd be it for sure. And then soon we'd both be off to school. Damn. I forced myself to concentrate on the here and now and to worry about tomorrow later.
My shift finally ended and I hurried home. After changing clothes, I tried to play some video games while I waited. She was late. About a half hour after she normally would have been home, she texted me.
*out with Tina. Won't be home for supper.*
Dammit! Ugh, I was a little shocked how jealous and upset that made me. I took a while to calm down, then resigned myself to the fact nothing was going to happen tonight, or probably ever again. I grabbed some leftover pizza, though I really didn't feel like eating. Then I went to my room and played World of Warcraft.
I heard Lucy come in around 10:00. I wasn't sure what to do. I was such an idiot. As I contemplated going downstairs to talk to her, I heard her come upstairs and enter the bathroom. Then I heard the shower running. I briefly considered trying to somehow spy on her in the shower, but I didn't really see how I could without getting caught and somehow felt that would be going too far, which was probably ridiculous of me to think. So I stood at my slightly open door the entire time she was in the bathroom . When I heard the bathroom door start to open, I quickly closed my door and ran to my computer, hoping she would knock.
She didn't knock.
Feeling confused and down, I went back to WoW. About twenty minutes later, she texted me again...
*come to my room in 10 minutes*
My heart may have stopped momentarily. I read the text five or six times to make sure it said what I hoped it said.
Just over nine minutes later I was knocking at her door. I was wearing boxers and a plain blue t-shirt. My cock was already half-hard and making a bulge at my crotch.
"Come in," her voice said.
I opened her door and stepped into her room. She was sitting up on her bed, facing the door. Her back was leaning against her headboard and she was above the covers. She was wearing her bathrobe, tied very loosely at her waist. Her legs were bent and I could see the inside of her thighs a long way up. A lot of cleavage was exposed too. Her hair was brushed back from her face and still wet from her shower.
"Close the door," she said, so I did.
I stood there looking at my sexy, curvy sister.
"I thought this time we could both cum," she said and I could feel my cock getting harder and could already feel precum leaking out of it.
"OK," I said and without her needing to ask this time, I lowered my boxers to show her my almost fully erect cock.
"Fuck yeah," she purred. "Get totally naked for me.
I kicked my boxers away and pulled my shirt over my head and dropped it to the floor.
"Damn, you know you've got a pretty nice body there, little brother."
The compliment made me feel really good and boosted my confidence through the roof.
"Thanks, Lucy," I smiled. "Your body is fucking amazing."
"Thanks," she giggled, and spread her legs a little wider, untying the robe at her waist as she did so and pulling it aside. I stared at her exposed body; her amazing, huge tits, down her smooth curvy belly to her hairless pussy. Holy shit, she was completely shaved down there and I could see her glistening pussy lips unfolding as she spread her legs.
"Come closer, come to the end of the bed," she said as she cupped her tits and caressed them. "Jerk off while you watch me touch myself."
My cock was rock hard now; almost painfully so. I moved to the end of her bed, leaning my knees against it. I grabbed my hard cock and began to stroke it while I stared at her.
"Mmmm," she sighed, her eyes on my cock as I jerked off to her. She spread her legs a little wider and her right hand moved down to her pussy. She began to rub circles over her clit, and I could hear how wet she was. God damn it was hot to watch her masturbate. My eyes were glued to her hairless mound and how her fingers would move up and down her wet slit and then concentrate on her clit. "Oh yeah," she moaned, her mouth open slightly and her tongue teasing her upper lip.
She tucked her free arm underneath her massive boobs, and they jiggled with her body as she played with her pussy.
"You like watching me?" she asked and I grunted in the affirmative. "You like jerking off watching your sister play with her wet pussy?"
Holy shit she was a dirty talker and it turned me on even more.
"Fuck yes, sis," I moaned. "God I fucking love watching you." I was already on the edge of orgasm; I couldn't help myself.
"I'm gonna cum soon," I grunted.
"Oh Yes. Are you gonna cum for me, you dirty boy?" she asked. "You wanna cum on my tits?"
"Oh fuck, yes!" I gasped and moved around to the side of the bed and up towards her while she turned towards me slightly. Her arm still pushed her big titties up and she stuck her chest out to me.
I leaned over and actually brushed my cock against her massive cleavage as I jerked off right in front of her. Her fingers were rubbing her clit fast now as she watched me stroke my cock and rub it on her juggs.
"Oh god, Mike," she gasped. "Yeah, cum on my big titties. Give me that hot jizz and I'll fucking cum too."
I moaned really loudly as I started to cum. I pressed my cock head against the smooth skin of my sister's big tits and shot a jet of hot spunk across them. Her body shook as she watched my cock explode.
"Ohhh, fuck, Mike!! I'm cumming!" she sighed as I rubbed my cock on the areole of her right breast and spurted more hot cum. She grunted low and deep as her body rocked with her orgasm just as mine was ending.
She came for a very long time, and when she finally stopped, she leaned back against her headboard again, breathing deeply.
I stood there staring at her; my curvy sister sitting naked on her bed, recovering from an orgasm, with my sperm on her tits.
"That was intense," she breathed finally, giggling. "I hope you enjoyed that, little brother."
"Oh fuck yeah," I said, again probably looking like a pathetic goof wanting more. "I hope we can do it again..."
"That would be fun," she said, pulling her robe around her again and getting up out of her bed. "But mom and dad are back tomorrow. I don't really know if we'll get another chance."
She walked by me and kissed me once, briefly on the lips.
"It was fun, OK? But let's not get our hopes up." The way she said it made my heart sink; it sounded like she didn't really want to do it again. She giggled. "Hey don't look so sad! You had fun, didn't you?"
I had to admit I did.
"OK," she said. "I've got to have another shower to clean up." She stood beside me, and took a good long look at my cock. "Mmmm! You've got a great cock, bro! See ya later!" She left her room and went back to the bathroom, and I didn't see her again that night.
Mom and dad returned home the next day. Lucy and I acted like nothing had happened between us. I jacked off numerous times the next couple days thinking about what we had done together. I still had hope that maybe we'd somehow find time to do it again, but Lucy didn't give me any signs that she wanted that. I resigned myself to the fact we wouldn't have a third encounter.
Less than a week after mom and dad got back home, Lucy proved me wrong again.
