Slippery When Wet

"Wow," I whispered.

"Thanks," she whispered back. Then she bent and picked up the bottle of lubricant and stepped over my legs.

When she squatted down onto me I couldn't help but imagine her guiding her pussy down onto my hard dick. I kept my eyes carefully on hers the whole time and hoped I didn't give away my incestuous thoughts. It was a sort of relief to feel the soft cheeks of her ass settle onto my thighs.

I closed my eyes when I felt her coating my shaft with slippery lube, but had to look when I felt the heat of her pussy pressing against the base of my shaft. She looked at me guiltily and bit her lip.

"This is wrong, isn't it?" she whispered.

"Probably," I croaked. "But it's only fair." She looked at me questioningly, so I explained, "You're taking care of my needs when you do this. You should be allowed to enjoy it; to take care of yourself, too."

"Yes," she hissed, pressing her hips forward to force my shaft between her drenched pussy lips.

Her oily fingers insistently stroked my shaft and circled the throbbing head of my dick. "Oh, that's so good," I moaned. Her breasts seemed to throb in front of me, like her entire breasts were getting erect rather than just her rock-hard nipples. I realized I was staring and practically drooling, and I looked up at her face again.

"Sorry. I was staring," I muttered.

"Do you like my tits?" she growled in response.

I let my eyes drift back down to them and sighed. "They're incredible."

Her hips bucked more insistently, driving her smoldering pussy against the base of my shaft even harder. She shuddered and I felt her coming, and of course that made her breasts wobble. Her entire body looked so fucking sexy I literally drooled. Then I sucked that saliva up loudly and swallowed, wiping my lips afterward.

"Wow," I croaked again.

"God, you make me feel so fucking hot!" Stacy groaned. "Are you getting close?"

"Yes."

"Oh, fuck," she moaned. "Are you going to shoot more of that hot cum all over my body?"

"Oh, damn," I groaned.

"Are you going to squirt it all over my tits? Is it going to coat my hard nipples?" She stroked me faster, pointing my dick directly at her left nipple again.

"I'm so close!" I gasped.

Then she got a wild look on her face and scooted her butt back down my thighs. She pointed my dick lower and growled, "Oh, you're so dirty, Keith! Are you going to shoot all that hot sperm right onto my wet little pussy?"

"Don't!" I gasped, but it was already too late.

"Oh, fuck!" my sister cried out as my molten semen shot out and splattered directly onto her clitoris.

She kept stroking my shaft frantically as she directed every thick stream of my cum onto her horny little pussy. It was another intense climax for me, and it was obvious that it triggered an equally intense climax for my sister. When the last of my load drizzled over her pulsing pussy lips, she lifted my spent cock up onto my belly and then collapsed on top of me. Her breath came in ragged gasps and her hard nipples pressed into my ribs.

"I can't believe you did that!" I gasped.

"That was really dirty," she murmured into my chest. Then her lips found my sensitive nipple and she moaned as she nuzzled it. Her tongue snaked out and twirled around it twice and then she gave it a soft kiss. She looked up at me then and shook her head. "I can't believe how hard I just came," she groaned.

After looking into each others' eyes for a couple of minutes, we finally caught our breath. Stacy seemed a little embarrassed she had let things go as far as they had, but she didn't say so. Instead she sat up and grabbed the towel. "We're so messy," she murmured with a little chuckle as she wiped me clean.

I couldn't help but stare at her when she stood up. My creamy dick-juice was all over her smooth pussy and coated the insides of her legs. She smiled down at me and then retreated to the bathroom. I waited for a moment before I finally sighed and sat up. I maneuvered over by the couch and pulled my shorts back on, then rolled back over toward the towels to grab my shirt. After I had pulled my shirt over my head and smoothed it into place I levered myself back up onto the couch.

That was when I heard Stacy start her shower. I frowned and turned my head in the direction of the bathroom door, and couldn't help but wonder what she had been doing. Unbidden, I pictured her playing with my sperm and licking it off her fingers. I shuddered and closed my eyes, trying to think of something else. I was a little afraid what might happen if she came back out to find me hard once again.

* * *

After she had showered and had the chance to cool off, Stacy was subdued and thoughtful. She came out with a bath towel wrapped around her, and was careful not to flash me as she crouched down to pick up her clothes. We looked at each other a little warily, like we were both afraid to say anything. She retreated to her room to get dressed. When she came back out, she sat next to me again and picked up her laptop without saying a word.

The silence between us stretched out long enough to make me uncomfortable, so I finally looked at her and blurted, "Thank you, Stacy. I appreciate you taking care of me."

She smiled softly and licked her lips nervously. "You're welcome," she murmured. Then she shook her head. "That got out of control in a hurry."

"Yeah," I sighed. "In a way, though, it was a relief for me. I felt...guilty? When you got me off before, I felt like I owed you for that. I just couldn't think of an appropriate way to ask if I could get you off without it sounding like I just wanted to see your pussy."

Her eyes glittered merrily. "So you're relieved because you got to see my pussy without having to ask me?"

I grinned back at her. "Well, you do have a beautiful pussy. I'll bet it's delicious. But what I meant was that it was a relief to see you getting off with me. I feel better knowing it was good for you, too."

"It was..." she bit her lip and shook her head. "But maybe it was a little too good. Do you know what I mean?"

I nodded and gave her a somber expression. "Yeah, I know exactly what you mean."

After the news ended, I surfed through the channels aimlessly for the next hour and a half. I felt my dick hardening and tried to lift my left leg to shield it from my sister's vision, but that didn't work. She saw the movement out of the corner of her eye and immediately saw my dick tenting out the front of my shorts. She let out a sigh and stood up.

"Come on, let's take care of that for you," she said.

I slid my shorts down my legs again and slithered over to the towels on the floor once again. Stacy didn't remove any of her clothing this time, nor did she straddle me. What followed was more like what I had considered a "hand-job" would be like. Oh, it still felt nice when she lubed up my dick and stroked it, but this was brisk and businesslike, and she brought me off quickly into the waiting towel. After she had squeezed the last of the cum out of my shaft and wiped me clean, she looked at my face.

"Better?" she asked.

I nodded. "Thanks," I murmured.

She just nodded back at me, and then she headed into the bathroom to rinse out the towel. I got dressed by the time she tossed the towel into the washing machine. My sister did not look happy as she walked over and took her place next to me on the couch.

"What's wrong?" I asked.

She let out a long sigh and shook her head, looking at my face. "I know it's wrong, but I didn't like that nearly as much."

"Me neither," I replied. Then I shrugged. "It was still probably the smart way to go about it."

"Yeah," she replied unhappily.

An hour later we headed off for my physical therapy appointment. I had put on underwear and cargo shorts as I usually did. I didn't mind the discomfort for these brief sessions and didn't want to risk giving everyone at the clinic a show if I got one of those spontaneous erections. Summer gave my legs a thorough inspection after we told her what had happened. She called in one of the doctors to double check. They agreed we should be cautious but didn't detect any obvious signs of damage.

I was basically forbidden from exercising further over the weekend, and they scheduled an MRI for Monday afternoon. That was disappointing, but it was really about what I had expected. I knew it would be foolish to take any chances, so I tried to remain calm. Stacy could read my unhappiness and reached over to give me a reassuring squeeze on my shoulder, once we were in her car.

"I'm sorry, Keith—"

"Not your fault," I cut her off. I shook my head and then looked over at her. She looked miserable, and I felt the need to reassure her. I reached over and squeezed her thigh. "Hey, if it wasn't for you, I would probably have wound up in the emergency room yesterday. You have been awesome. Thank you."

Her face brightened immediately, and I felt my heart swell in my chest. "Damn, you're beautiful," I breathed. It came out without thought, and my sister's eyes widened. I'm sure mine did too. I opened my mouth, but then shut it and shook my head. I smiled at her and said, "Nope, I'm not taking it back. It's totally true."

"Oh, you fucker," she growled.

That caught me off-guard. "Excuse me?"

I felt anger flare inside me—the result of all the hormones raging inside me from that day's medications—and I squeezed down on my sister's thigh, hard. Her eyes flew open and she gasped.

"I'm sorry!" she said. She slid her hand down from my shoulder to my chest. "That didn't come out right, Keith. Please don't be mad." Then she reached for my wrist. "Please, Keith," she murmured, "You're hurting me."

I looked down and realized how hard I was squeezing her thigh. Immediately, I released her and jerked my hand back. Angry red fingerprints marred her pale skin.

"I'm so sorry," I mumbled.

She still held my wrist, and she gave it a gentle squeeze.

"We should get some lunch," she said softly.

I nodded and she started the car. I still felt bad, and of course I was overly emotional because of my crazy-ass hormone levels. It was all I could do not to cry. I took slow, deep breaths so I could calm down, but then I started thinking, Why did she say that?

I was still puzzling over it when we pulled into the parking lot at our favorite Chinese restaurant. They had an excellent buffet and my mouth was watering before we had even parked the car. Stacy hopped out and got the wheelchair out of the trunk. When she rolled it around to my side of the car, I was shocked to see how hard her nipples were beneath her blouse and bra. Then my mind replayed her growling, "Oh, you fucker," and it hit me—she had been turned on!

Lunch was a welcome distraction after the emotional roller-coaster I had been through. Everything smelled amazing and I had to fight the temptation to fill my plate with everything the buffet had to offer. Not all of those foods would play well together in my stomach, and I managed to keep it in mind. I ate my lunch and finally looked across at my sister when I heard her chuckling.

After swallowing I asked, "What's so funny?"

"You," she replied, smiling and shaking her head. "The way you're moaning, it sounds like someone's under the table sucking your dick."

I stared at her. First, I wasn't aware I had even been moaning. Second, she had planted that image in my mind. My over-eager dick responded instantly and I stifled a groan. My only relief in that moment was that there wasn't anyone nearby to hear what she had said.

"Um...sorry?" I finally managed to reply.

"No need to apologize," she replied, still smiling. "At least I know you're really enjoying your lunch. Hell, everyone can hear how much you're enjoying it."

I had to look around then, and sure enough several people were looking our way and smiling. I smiled back at them sheepishly and resumed eating my lunch. When I wheeled back over for seconds, I heard a couple of people chuckling softly. I studiously avoided looking at them. Inside, I was just praying none of them could see my erection through my thick shorts.

* * *

We were almost home before I felt the need to blurt out, "Stacy, I am really sorry I snapped at you earlier. I know you weren't trying to be insulting. I just misunderstood and overreacted. You know I would never hurt you like that on purpose."

She shot me a quick glance before returning her attention to the road and making the turn onto our street. Then she stuttered, "We'll—we can—it's—" She blew out a frustrated breath and shook her head. "I understand," she said firmly. "We can talk about it when we get inside."

It was only because I was looking at her so intently that I noticed the way she squeezed her thighs together.

We pulled into the driveway a minute later and she got out to unfold my wheelchair and roll it over to my door. Once again I noticed her hard nipples protruding through her blouse as she held the wheelchair steady and I slid into it. That was surprising. I couldn't see her at all when she rolled me up to the house, but when she walked around in front of me to unlock and open the front door I noticed that her legs were shaking.

It was subtle, but I couldn't miss it. I also couldn't miss how incredibly sexy my sister's ass was in those snug shorts. My dick was completely hard by the time she rolled me inside the house and closed the door behind us—hard enough that she could see it as soon as she turned around. Before I could say anything, she looked past me and her eyes widened again.

"Oh, damn," she murmured. "We didn't put any of that stuff away."

I rotated my chair to take a look. It took me a second to realize she meant the beach towels and the pump bottle of lubricant. Stacy walked up and took the handles on the back of my wheelchair, rolling me out into the living room. She leaned down to whisper in my ear.

"Mom and Dad won't be home for another hour. We should go ahead and use the towels one more time before I put them away."

"Oh, okay," I replied.

I expected another quick hand-job like the last one, but only because I had ignored all the obvious signs. I unbuckled my belt and slid my shorts and boxer-briefs down my legs, then slid down and positioned myself on the beach towels. When I looked up at Stacy she had already removed her blouse and bra, and she was sliding her shorts and panties down her legs. I gulped and stared at the perfection of her naked body.

"Take off your shirt and socks," she reminded me.

I quickly whipped off my shirt and then bent to remove my socks. My eyes were glued to Stacy's body when she bent over in front of me to pick up the bottle. Her sexy ass cheeks spread just slightly and I could see the glistening lips of her pussy, as well as the cute little button of her asshole. The groan that came out of my throat couldn't be helped.

"Were you staring at my ass?" she growled as she straddled my thighs once again. I gulped and nodded, and watched her squirt the lubricant over her hands and the head of my throbbing dick. "You're so bad," she murmured in that deep, throaty voice. "I'm your sister. You know you shouldn't look at your sister like that." She worked the slick lube all over my cock and licked her lips before looking up at my face again. "Oh, wait!" she gasped. She slid forward and pressed her wet folds against the base of my slick shaft. "Were you looking at my pussy? You were, weren't you? Oh my God, were you thinking about sliding this huge, hard cock into your own sister's wet little pussy?"

I swear, my dick got even harder in her hands when she talked that way. All I could do was stare at her and gulp. She shook her head and licked her lips.

"You're my little brother," she continued. "You really shouldn't think such dirty things. Of course, if you weren't my brother, this thick, tasty-looking dick would already be inside my pussy. I'll bet it would feel amazing as it stretched me wide open."

She started humping her hips forward and back, sliding her pussy up and down the shaft of my dick as her right hand pressed it against her. The fingers of her left hand were teasing and circling the pulsing head of my cock, making it swell up impressively. Between her delicate fingers, the slick knob looked enormous.

"Wow," she breathed. "I still can't get over just how big your dick is." Her eyes then roamed hungrily up the flexed muscles of my midsection and on over my chest and shoulders. She shuddered and licked her lips. "It's bad enough you have the body of a Greek god," she shifted her grip and slapped the shaft of my cock against her pussy twice. "This is just unfair."

She shifted her hips upward just a little and shook her head again. Our eyes were locked as she stroked my wet shaft and the fingers of her other hand pressed the head of my cock against the top of her pussy. As if the slippery lube wasn't enough already, her pussy juices were flowing onto the underside of my dick and drenched it further.

"Damn, that feels incredible," I croaked weakly.

"Yes!" she panted. "It does feel incredible." Then she pumped her hips insistently again, and the head of my soaking-wet dick was sliding up and down between the lips of her baby-smooth pussy.

Her eyes shot open and she looked down frantically when her right hand slipped completely up off of my shaft. Without that hand holding me in place, her other hand pushed the head of my cock between her drenched folds. We both gasped at the intense sensation and I glanced down just in time to see my throbbing cock head slip inside my sister's pussy.

Her right hand struggled desperately to get a grip on my shaft, and I felt it bending slightly as she pulled on it. Then her hand slipped off again and another inch of my dick slipped into her.

"Oh fuck!" she gasped.

I was frozen in place, watching my sister shudder all over. She looked incredible and at the same time helpless as my thick cock slipped deeper inside her. Her eyes were wild when she finally looked up at my face.

"Help me!" she gasped desperately.

Her words galvanized me into motion. I sat up and reached down to grab her hips. She was surprisingly light and I lifted her up off of my dick. I heard it slap wetly against my abdomen, but was too distracted to look down at it.

My sister's hard nipple had pushed right into my open mouth.

We groaned in chorus as my lips closed on that irresistible, throbbing tit-flesh and I started sucking on it hungrily. Stacy wrapped both hands around my neck and shuddered in my grasp.

"Oh, damn," she panted, practically into my ear. "That feels so fucking good. Oh! Oh, shit!"

I felt wonderful, warm wetness engulfing the head of my cock. I was completely focused on sucking my sister's breast and it took a full minute for me to realize that my hands had pulled her down onto me. By then, half my dick was inside her and I was already guiding her up and down on it. Stacy was too busy coming all over my swollen cock head to protest.

It just felt too fucking good for either of us to stop.

My sister's pussy was incredibly tight, but with all that slick lubrication my dick slid deeper inside her with each stroke. In another minute she was taking me balls-deep each time I pulled her hips into mine. She came two or three times in rapid succession. It was tough to tell, the way she was trembling and bucking her hips the whole time. All too soon we hit that rapid pace that drove me beyond the point of no return. My cock swelled and my balls bucked upward. At the last second I released her nipple with a gasp.

"I'm gonna come!" I gasped, looking into her eyes.

Her eyes shot open once again. "Don't you dare!" she cried. "You can't come in my pussyyyy! Oh! You fucker!"

It had already been too late by the time I said a word. Stacy's hips just kept bucking against me as I unloaded deep inside her. I was a little concerned when I heard her sobbing into my neck. It was tough for me to get the words out of my mouth since my cock was still shooting my hot cream into her spasming pussy, but I managed to stammer out four words.
