Mind If We Park?

The sound of our mom’s voice coming down the hall froze us both in place, my cock buried in Tabby’s cunt. Horror overwhelmed our senses, causing me to go limp quicker than ever. I pulled out of her as we both scrambled to our feet, hoping beyond all hope that our parents didn’t decide on a bathroom break right as they got home.

“What do we do?!” Tabby whispered fearfully. “They don’t know that I know about you!”

With my room being the only connected room to the bathroom, I started thinking quickly. “I’ll get out and get to my room,” I whispered. “I’ll pretend I was still asleep. You act like you just got done in here. That’s the only way this will work.”

She nodded in hurried agreement as I lifted my bathrobe to put it back on in a rush. Tabby grabbed a fresh towel from the shelf and wrapped her hair before grabbing another to wrap around herself. As I started toward my bedroom door, she quickly pulled me back around and planted a hard kiss on my lips.

“I want to finish what we started, OK?” she whispered. “We can pick it up at my place this time around. No interruptions there.”

I just nodded eagerly, the thought exciting me to no end. If we weren’t both so scared of being discovered, I probably would have grown rock-hard at that moment. I gave her one last passionate kiss before sneaking back into my room and climbing into bed, throwing the covers over me completely. I listened intently as footsteps came down the hall, pausing right outside my door. As I heard my doorknob start to turn, it was followed quickly by the bathroom door opening in the hallway.

“Mom! Hey, I heard you call out. Bee’s still sleeping, so I thought I would take a shower. Everything ok?” Tabby was the queen at improvisation, I had to admit. I probably would have caved the instant I saw my parents.

“Things are fine. Just a minor thing with your grandmother. Now, how about you clean up that mess in the kitchen after you get dressed? And try to keep your laundry in the basket next time, OK?”

Shit, I had completely forgotten Tabby had stripped completely in the kitchen. Good thing Mom wasn’t the wiser about it.

“Heh, right. Sorry, Mom. I’ll get on it.”

“Now I’ve got to get your sister up. She’s got her appointment today,” Mom said. A second later, my door opened and Mom stepped in. “Sweetheart, it’s time to get up. You have your appointment with Dr. Hyster in a couple of hours.”

I made a couple of groans and put a thumbs up to her out of my covers, trying to keep myself hidden and pretend she had just woken me up. It must have worked because she closed the door and walked away, back to the kitchen or living room if I had to guess. I threw my covers off and sat up in bed, huffing a little at the predicament I had barely escaped. It was that moment I realized I hadn’t dried myself at all when I saw my pillow was completely wet.

“Way too close,” I said to myself as I got up and dressed, hurriedly getting a towel to dry my hair.

The doctor’s appointment went the same as it always did: a few tests, some discussion (including a small, specific one while my mom went to the bathroom), and the end result being that I’m still a perfectly healthy young woman who happens to have some added equipment. Thankfully, Dr. Hyster kept my private discussion with him quiet. I’m pretty certain, given recent events, you could imagine what it was about.

Once we got home, Tabby suggested to Mom and Dad that I spend the night at her apartment. Her excuse? “We haven’t had a true girl’s night out since my birthday, and I want to treat my baby sister to a night she won’t forget,” she said. The hidden innuendo flooded my mind and had me hopping with anticipation. My parents agreed, so I packed a few things and off we went.

As we were driving to her apartment, we got into typical girl conversation: clothes, food, you name it. It was really nice to connect with Tabby as a sister again. We still had a distance to go, so I decided to reveal what I had talked to the doctor about.

“So, I talked to the doctor today, but I had to be sneaky about it,” I said. “I didn’t want Mom to hear about what I wanted to ask.”

“Do you mean… what we talked about this morning?” she asked. She had a slight frown on her face, not sad but more apprehensive. I guess she was nervous that I was talking about my sex life with a complete stranger. “What did he say, exactly?”

“Well, he was a little surprised. It did kind of come out of nowhere. Still, he answered my questions and ordered a couple of tests to see if I could actually… you know, have kids.” I tried to remain as even-toned as I could, but talking about this kind of thing with your sister? It was a little embarrassing. The fact that I’d had my dick inside of her multiple times over the course of a day didn’t exactly settle my nerves. “He said I should have some results in a couple of days.”

“You’re serious?” she asked. For a moment, I thought she was going to say she was only kidding and that I shouldn’t have said or done anything, but she quickly followed up. “You’d be willing to do that with me?”

Butterflies were quickly building in my stomach as I heard the endearing tone of happiness in her voice. I put my hand on her leg and looked intently at her. “I know we just started having sex, and the fact that you’re my biological sister hasn’t escaped me, but… yes. I am. Only if you want to, though,” I added. For all I knew, she said it as a spur-of-the-moment reaction to calm me down this morning, but that hope kept building in me over the day. My answer came as she gently placed her hand on my leg, dangerously close to where my dick was now resting.

“I’d love nothing more, Bee.”

She gave me the sweetest smile I had seen in a very long time, and it put my mind at ease. I breathed a sigh of relief and squeezed her leg reassuringly. She, however, moved her hand up my leg until it brushed against the tip of my dick, separated only by the thin fabric of my skirt. The move made me gasp in surprise and excitement and her hand moved on top of it, giving gentle strokes to my now-hardening member.

“You know,” she whispered, her face now showing a mischievous grin as she focused her eyes on driving. “I’d also love having this back inside me, maybe even get a head start. Ready to pick up from this morning?”

She didn’t even need to ask as her soft hand had already made my dick start to tentpole my skirt quite noticeably. As my hand was still on her leg, I decided to repay the stimulation she was giving me with some of my own. I slid my hand up her thigh until it rested just against her pussy, her leggings betraying the heat emanating from her. I began to rub my finger against her, feeling her womanhood dampen through her pants.

“You have no idea how good that sounds,” I whispered. I slid my hand higher to the waist of her pants, wriggling my fingers underneath. At the same time, she was hiking my skirt up, **** to reveal my now throbbing erection to her gentle grasp. Both of us were breathing rather heavily as our fingers found their destinations. Her gentle fingers wrapped around my now stiff dick as mine began roaming her slick pussy. Her eyes were half open, my fingers causing her to lose a small amount of her concentration if I had to guess.

“Fuck this,” she exclaimed as she veered off into a parking structure, which appeared to be empty for the most part. She circled each floor before almost reaching the top where no cars were visible. She did another lap around, my guess would be checking for cameras or guards or something. As soon as she was satisfied, she pulled into a space that was in almost total darkness.

“I don’t want to wait until we get there. I want you now.” As she spoke, she was tearing off her clothes until she was finally completely nude. She then reached for my skirt and started tugging it down. Lost in the moment as I was, it took me a couple of seconds to join in stripping down. By the time we were both undressed, she was straddling my lap, my stiff cock pressing against her stomach. She didn’t waste any time as she lifted herself up as much as she could in her car and guided my dick inside of her sopping wet pussy.

Whether it was because of how much we’d done it already or how excited we both were, I don’t know, but my cock managed to sink into her quickly. I no sooner bottomed out inside of her burning cunt than she lifted herself up and slammed herself back down. The slow intimacy we shared last night or this morning in the shower was not there. This was more like a fiery desire, a crushing need, for her to ride me.

She didn’t want to make love this time. No, this time she wanted to be fucked.

Her tits bounced wildly as she rode me, my hard dick slick with her juices as it rammed in and out of her. It was an experience like nothing else. I’d always been a bit of a softie, you could say, but in this moment I wanted nothing more than to be rough. As much as she wanted to fuck, so did I. I held her hips tightly as she ground her hips down on me, taking me all the way inside of her. Her moans became louder as her excitement climbed.

“Oh god, Bee! Yes! Fuck me! Fuck me hard!”

I kept feeling myself hit her innermost parts each time she slammed back down on me, and it felt incredible. Sweat began to bead on our skin as our furious fucking rocked the car side to side. Tabby’s tits bounced right in front of my face, hypnotizing me as her erect nipples drew crazy circles in the air. I couldn’t help myself as I hungrily took one into my mouth, sucking it hard as I moaned into her breast. Her hands flew to my head, locking it in place as her hips kept their rhythm of pounding down on me.

“Yes, Bee! Suck it! I’m getting so close!”

Suddenly, as if waiting for the perfect moment, lights from the far end of the garage pierced the glass of the windshield, making us freeze in place. I peered around Tabby as I saw a car approaching us slowly. Without thinking, I lifted the handle for the seat to lower it back completely, shocking Tabby with the impromptu move. My dick was still buried deep inside her to the root, her heartbeat palpable against my cock. The lights appeared to get closer until they finally turned away, going to the next level down. Tabby and I stayed still for a few seconds longer, just until we were sure the other car was gone, then breathed a collective sigh of relief.

“That was way too close, Tabby,” I said. “Maybe we should w-” My sentence was cut off as Tabby’s hand covered my mouth. She gave me a soft shush as she sat up on top of me, inching my dick deeper inside her again.

“Sorry, Bee, but I can’t stop yet,” she whined. I could feel her pussy squeeze around me as she started to move again, slow at first but getting faster with each stroke into her. Her hands clasped mine and guided them back to her hips, locking them in place. Sweat was starting to stream over her body, her nipples flinging a drop or two as they bounced in the air. She moaned so loud it was a wonder the sound hadn’t carried to the other levels of the garage. Her eyes were shut tight, the feeling of pleasure making it too hard to keep them open.

“God, Tabby! You’re squeezing me tight!” I exclaimed. Indeed, it felt as if her walls were getting tighter around me, seemingly sucking me further in. At one point, it felt as if I was going to punch through her cervix straight into her womb. The delirious sounds she made only cemented the thought in my head that she was experiencing what must have been an insane amount of ecstasy.

Then I felt a pop as I actually did enter her womb.

Her eyes sprang open wide as she gasped at the sudden invasion of my dick into her womb, feeling what I could only imagine was an immense amount of pain. She sat there, my dick now completely inside of her, gasping heavily as she just stared at me in complete shock. I was absolutely terrified that I had seriously hurt her, but I couldn’t move an inch.

“Tabby! Oh my god, I’m so sorry! Are you ok?! Here, let me help you off!” As I tried to lift her, she pinned my arms down, not allowing me to move. She had closed her eyes tightly, biting her bottom lip in pain. She looked as if she was about to either scream in agony or cry in terror.

I was wrong on both counts.

“Just... let me... adjust a little. I feel… so full right now,” Tabby groaned. “If you move, I’ll definitely cum! Just let me enjoy this before you set me off!”

She wasn’t the only one who was teetering on the edge. The insane tightness of her womb was milking my cock for all it was worth. I felt like if I moved, I’d immediately flood her fully. Still, sitting there with my entire length buried inside of her was proving enough to send me over.

“Tabby, I don’t think it matters now!” I groaned. I could only ball my pinned hands into fists as I tensed and pushed my hips up, lifting both of us off the seat as I erupted directly into Tabby’s unprotected cunt. Tabby gasped and looked down at where we were joined, feeling the pulsing of my monstrous cock inside her launch her own orgasm. She fell forward on top of me, muffling her screams of pleasure in the headrest underneath my head. Her body shook violently on top of me as I felt my seed surround the head of my dick inside her uterus.

If there was ever a chance of me actually impregnating her, I would say that was probably it.

We both lay there, heavily breathing as we recovered slowly. The occasional twitch from my still-buried dick caused a new wave of blissful aftershocks to roll through her, making her shiver in pleasure. After what seemed to be an eternity, my shaft fell free of her womb, popping gently out of her dripping gash. A small pearl of my futa cum dotted her entrance.

“Oh my god… Bee, that… that was…. Wow,” she whispered hoarsely. “I can’t... believe... you went all the way… inside me. Mmm, it… I can still…. feel you…. in there.”

It took me a while to regain my wits, but I unclenched my fists and ran my fingers through her hair, pulling her head so our lips could meet in a passionate, fierce kiss. We could be discovered at any moment by anyone curious enough to look past our fog-covered windows, but I didn’t care. I had Tabby in her most **** position, and she had me likewise. Her skin felt cool to the touch because of the sweat, but it hid the fire burning inside her as we kissed.

After we recovered, we redressed ourselves as best we could in such a confined space, laughing the entire time. Once we cleared the windows of the steam we created, we began our journey back to her apartment, free to play with each other as much as we wanted.

So of course, that is not what would end up happening.
