Spending the summer with my grandparents has always been boring, but every summer, my mom would insist that I spend time here. She’d drive us up for a visit and leave me here until the end of summer when my aunt Liz would drive me back home. I would have thought all of that was behind me now that I was sixteen, but nope. Now, I was old enough to be a real help around the house, so Grandpa put me to work. The only thing that made this summer bearable was my mom’s little sister, Liz. She still lived with my grandparents to help them out the best that she could. I liked her because she actually seemed interested in my life, even though I jokingly called her my creepy aunt because she always asked a lot of personal questions.
Liz was what I would call thick but not overweight. You know the type—athletic thighs with a nice round butt, with a huge pair of titties. Mom used to say that Liz was adopted because no one else in the family was that well-endowed. She often joked that I would disappear in Liz’s cleavage whenever Liz hugged me. “Like Timmy down the well, They’ll have to get the fire department to extract me from aunt’s cavernous cleavage.” Staring at her tits all summer long almost made all the hard work worth it.
The morning that Liz was supposed to drive me home, I accidentally walked in on her in the bathroom when I went to pee. I was still half asleep and stumbled in as she was stepping out of the shower. Her giant tits hung there in full sight, sending a tingle through my balls. While I ogled her heavy breasts, she zoomed in on my piss hard-on straining in my sleep shorts. I stammered an apology and went back to my room. It truly was an accident.
A few minutes later, Liz came barging with her bathrobe still open and caught me jacking off. She stood there full frontal nude, mesmerized by streams of cum shooting across my stomach. There was a twinkle in her eyes as she watched the last of my spurts of cum land on my chest. “Go get cleaned up. We’re leaving right after breakfast,” she said as she closed the door.
It was a long drive, and Liz was hoping to make it without having to stop for the night somewhere. I was surprised by how quiet she was for the first hour or so and wondered to myself if she was embarrassed about me seeing her naked. Or maybe she was replaying the memory of the ropes of cum shooting out of my cock.
“Do you do that a lot?” she asked.
“What?”
“Masturbate. Not that there’s nothing wrong with it. I’m just curious if it was because you saw me naked or if it’s part of your morning routine.”
Not wanting her to know that I had been jacking off to her tits all summer, I stayed silent.
“Do you always cum that much, or was it because you got to see boobies for the first time?”
I told her that I had seen boobs before, just none as big as hers.
“Have you ever touched one or held one in your hand? Copped a feel or sucked on a nipple?”
I shook my head, mumbling, no, dreading the coming interrogation.
Liz got quiet again for a few minutes, staring out the windshield. I could tell that she was thinking about something, but nothing like what came out of her mouth next.
“Are you going to tell your mom that you walked in on me in the shower?”
“No. Are you going to tell Mom about me, you know, when you walked in on me?”
“No. I can keep it a secret if you can.” I remained silent. “Good. Then maybe you’ll get another chance?”
“At what?” I asked
“Another chance to see my boobs, of course.”
I let out a nervous laugh, hoping that she didn’t notice the growing bulge in my pants. I definitely didn’t want to let on that I’d do anything to bury my throbbing cock between her titties and come all over them. The more I tried not to think about it, the harder my cock got. I asked where that would happen.
Liz laughed, “We have a long drive ahead of us and need to do something to pass the time. You never answered me if you’ve ever touched a boob before.” My silence gave me away.
“I didn’t think so,” she said, pulling her tit out of the bottom of her bra. “Go ahead and touch it if you want. I know that you’ve been checking them out all summer, so go ahead and touch them. You know you want to.” I reached over and grabbed it, squeezing it, causing the underwire of her bra to poke her in the neck.
“Here, Take the wheel,” Liz said, leaning forward to unhook her bra. She then slipped her arm through the strap, slipping it off. “Here, now, you won’t kill me when you play with them.”
I squeezed her breast, lifting it slightly to judge the size. It was the biggest boob that I’d ever seen. Way bigger than my mom’s tits.
I always found nipples fascinating. They seem to have a mind of their own, growing erect at will. Uncertain if it was because of arousal or the flow of cool air from the air vent, I tweaked Liz’s nipple as it grew erect, rolling it between my fingers and causing Liz to moan. I leaned over and sucked her nipple into my mouth, giving it a swirl with my tongue.
“Hey, I didn’t say that you could do that,” she giggled. “I’m kidding. You can keep going. I liked it.”
As I nibbled her nipple, I slipped my hand under her skirt and rubbed the front of her panties. They were damp. Moist to the touch. Taking this as a sign that she was aroused, I slipped a finger into her panties in search of her vagina. She leaned her seat back a bit to give me better access to finger her cunt, so I continued to finger fuck her until she came.
“Take your cock out and show me how hard I made you,” Liz said, pulling the front of her shirt down.
I was reluctant, but she insisted that she reciprocate in kind. I undid my pants and slipped them halfway down my thighs, so she could see how big my cock really was. Liz told me to turn to face her so she could stroke my cock. Again, I did as she asked and turned towards her, leaning against the passenger door.
Liz spit into her hand before she took hold of my cock. Her fingers wrapped around the thickness of my cock, stroking it a few times before she ran her thumb over the tip. Aunt Liz continued this until she worked up a large bead of precum on the tip of my cock. She wiped it up with her thumb and popped it into her mouth. Liz took my cock back in her hand, stroking the length of my shaft while rubbing her thumb along my vein. She would spit in her hand every few strokes, making it glide smoothly through her fingers.
I thought I was adept at jacking off, but it never felt anything like what she was doing to my cock. I wondered if that’s what a tongue felt like as she swirled her thumb across the tip. The thought of Liz sucking my dick sent a jolt through my nuts, and I began to squirt. Liz covered the tip of my cock, letting me squirt into her palm. She gripped my shaft tightly, scooping as much of my creamy cum into her hand. Liz brought it to her mouth and licked off every drop. “Bet that’s the first time that’s ever happened. “Are you going to alright like that, or do I need to pull over and lick you clean too?”
I didn’t even have time to respond before she pulled off the next exit. Before I knew it, we were parked in a ride-share lot just off the freeway. “Lay your seat back,” she said while unhooking her seatbelt. Liz’s warm mouth engulfed my cock. She sucked it while swirling her tongue around it, licking off the remains of my spunky load. Her swirling tongue combined with the suction of her mouth was enough to me my cum again.
I grabbed Liz’s head and thrust my cock deep into her mouth as I pumped it full of cum. Two, maybe three thrusts were all it took to empty my balls a second time in less than five minutes. I could feel Liz’s tongue and throat clench each time she swallowed. She came up, smacking her lips like one does after swallowing something tasty. “You better pace yourself, boy, or you won’t have any left for when we stop for the night,” she said with a devious smirk. “You only have so many in you before you have to build up your reserves, whereas you could make me cum all day, and I would be ready for more when we get to the hotel.” I had hoped that we would have to stop for the night ever since I walked in on her this morning, and after what just happened, I was certainly looking forward to more.
Liz’s comment about me making her cum all day stuck in my head, so when we stopped lunch, I asked she let me drive for a while. I could tell that she wasn’t really keen on letting me drive her car. She quickly changed her tune when I added that she could let me play with her some more. “You’d be able to lean back and really enjoy it,” I suggested. She called me a little devil as she tossed me her keys.
As soon as we were back on the road, Liz slid her panties off and shoved them into the glovebox. She turned to face me with her legs spread like she had me do earlier. I glanced down at her pussy and saw that her short and curlies were already glistening from her excitement. My finger slipped through her outer lips, penetrating her with ease. My god, she was even hotter than the first time that I fingered her.
I slid my middle and ring fingers inside her hot box, plunging them repeatedly up her snatch while I rubbed her clit with my thumb. Liz drew in a sharp breath as the first inkling of pleasure started to tingle her twat. She reached under her shirt and began to play with her nipples. “Let me see,” I said as I thrust my digits deeper into her twat.
Liz pulled her shirt up, slipping her head through the bottom but still leaving her arms through the sleeves. She looked awkward leaning against the passenger door splayed out next to me. She rolled and pinched her nipple while I continued to thrust my fingers into her hole. She bit her bottom lips and moaned for me to press up against the roof of her vagina. “Ah, God. Right there,” she exhaled. “Oh, Yes. Almost there. Mmph, ugh, gawd damn. That’s it. Right there!” Liz groaned, bucking her hip, grinding her muff harder against my hand as she climaxed.
I must have done her good cuz she dozed off right after she came. She didn’t even pull her shirt down to cover herself. She just laid there with her tits out. I adjusted the temp so cool air wouldn’t be blowing directly onto her naked flesh. I didn’t know whether to wake her or not, but I decided to let her sleep to conserve her energy for when we stopped for the night. I wasn’t sure what Aunt Liz had in mind, but I was looking to get laid for the first time.
Liz woke about an hour later, saying that she had to pee, so I pulled off at the next exit with a gas station. I filled the car with gas while she went in to pee. It seemed to take her forever to get back, and I was about to bust my bladder by the time she returned.
On the bathroom wall, there was a quarter machine that sold condoms and French Ticklers. “I wouldn’t buy any of those, son. You’ll probably get her pregnant or catch some disease,” an employee said when he saw me fish a bunch of change out of my pocket. “They got real rubbers by the registers.”
I lingered around the registers, waiting for the line to clear out some. I didn’t know which ones to get when it was my turn. I reached for the first box I saw but was stopped by the same guy from the men’s room. “You’re with that thick chick that was just in here, right? Get these lubricated ones, or she’ll ride you raw.” The guy tossed them on the counter. “Be careful, son. She looks like she could pick you up by the ankles and use you like a dildo,” he laughed. I was so embarrassed that I ran out without the rubbers. I was still beet red when I got back to the car. Liz asked what had taken so long as she pulled back onto the interstate. I lied and told her that they were cleaning the bathroom.
After a couple more hours, we pulled back off the highway, saying we should get some dinner. “Were we going to stop for the night?” I asked. “Earlier, you said that I had to build up my reserves when we stopped for the night.”
“Would you like to stop for the night? Would you like to see your aunty’s titties again? It’s okay if you’re eager for beaver.”
“Am I going to get any beaver?”
Liz crossed her arms under her breasts and leaned forward to accentuate her cleavage. “I don’t know about beaver, but I bet that you’d love to stick your boner between these for a good old-fashioned titfuck,” she said as she squeezed her tits together. I know I turned three shades of red when she did that.
Liz continued to flirt with me after we got to the hotel. She’d ask if I had ever tried this or that or how far I had gone with my girlfriend. I finally asked her right out if she was trying to get me horny. Liz grinned, asking if it was working. I leaned back on one of the beds so she could see the bulge in my pants. “Yeah, it is. What were you saying about a titfuck,” I asked. Liz told me that she was going to make me work for that. When I asked her what I’d have to do, she told me to think of a way.
Liz disappeared into the bathroom, saying that she was taking a shower. I thought about sneaking a peek, but I heard her lock the door. It was then that I noticed her purse had tipped over, spilling some of its contents on her bed. I didn’t want her to think I had gone through her purse, so I put everything back inside. In doing so, I saw a box of rubbers. The same kind from the convenience store where we got gas. She must have been thinking the same thing that I was. I closed her purse as soon as I heard the water shut off.
Liz came out of the bathroom wrapped in a towel. “Do you want to shower before we do this?” she asked as she tied her hair back. As soon as she lifted her arms to scoop her hair back, the towel fell to the floor. Once again, she stood before me in all her glory. She came over and knelt in front of me. “I’ll take that as a no,” she said as she grabbed my erect cock through my pants. Liz squeezed my cock, stroking it through the fabric. “Let’s see what you got going down here.”
Liz tugged down my pants, underwear, and all. “Is this what you wanted?” she asked as she pressed my cock into her cleavage. “You want to fuck your aunty’s big ol titties.” Liz dribbled spit onto the tip of my cock, telling me to go ahead and hump her tits. My cock was long enough to stick out the top of her crevice with each stroke.
Liz kissed the tip when it got close enough to her lips. Grabbing my ass cheeks, she held me tight so she could suck the tip into her mouth. She swirled her tongue around the head of my cock while she sucked. It was incredible. Liz did her best to keep the tip in her mouth as I continued to try to hump her titties.
Liz let her tits fall and took the length of my cock into her mouth, flicking her tongue along the vein. I was about to blow my wad right then. Liz must have felt my cock surge because she pinched the base of my cock hard and pulled my cock out of her mouth. “Remember what I said about pacing yourself, boy.” Liz sat on the edge of the bed. “Have you ever gone down on a girl before?” she asked as she spread her legs. She reached down and spread her pussy lips.
I’ve seen this done in plenty of pornos, but this was a first for me. I did what I’d seen on screen. I slid my tongue through Liz’s pussy lips and up across her clitoris. My inexperience showed, and the more I licked, the more it became a big, drooly mess. However inept, I did make Aunt Liz moan. Once anyway.
I shoved a couple of fingers into her pussy hole while I wiped my face on my sleeve. Liz started to rock her hips to the movements of my fingers. “Good. Like that. Rub my clit with your thumb, too,” she moaned.
I did as instructed, moving…
