As a Young boy, Mark, conquers Lisa, 19 yo's D-cups!

Mark, a young boy, out of his dept, besotted by visiting college student Lisa's D-cups, plans to make his tit-fuck fantasy come to life, willing or not.

A huge thank you to a reader named Max, who generously shared his history with me. His stories are raw, honest, and powerful. One fantasy in particular, from when he was just fourteen years old, captured my imagination. He also has an incredible, forbidden bond with one of his sisters—a story I can't wait to share later, if you want to hear it.
For this piece, I wove that fantasy together with the true, formative experiences of his childhood. The result is the story you're about to read. I hope you enjoy it.
Thank you again, Max.

The air in the basement was thick and still, smelling faintly of old carpet and the laundry detergent Mom used. It was a Tuesday, or maybe a Thursday—I never paid attention to the days when I was buried in the work of Kat. My sister.
Kat was busy giving me head, her lips felt amazing wrapped around my cock. She was a trooper, really milking my cock, looking for the cream. My small hands were buried in her hair, gripping lightly as I tried to stifle the moans rising in my throat. We’d been fooling around for years at this point, and she was fifteen, old enough to know what she was doing, young enough to still be discovering the thrill of it. We loved scratching each other's itch. At our age, we rarely had to masturbate on our own; we generally took care of one another. I could taste the salt on my tongue, a lingering reminder that I had been eating her out earlier that afternoon.
She would sometimes sneak into my room on a Saturday morning to swallow my morning wood, and we’d sixty-nine. She’d said she loved to start her day off with an orgasm, and if it wasn’t from self-love, even better. It was our secret ritual, a special bond that no one else understood.
But today, she was extra horny. We were enjoying our special bond. My cock was buried deep in her throat, the tightness and the wet heat overwhelming my senses. I was close to letting go when we heard Kim’s voice, loud and clear, floating down from the living room above. Then the sound of the back door closing with a heavy thud.
Kim was my 19-year-old sister, who had just started college. For the most part, she lived on campus and loved it, but from time to time she’d come for the weekends. She wasn’t due home at this time, so I was curious.
I looked down at Kat, who had paused, her eyes wide with panic.
“Keep going!” I hissed.
She didn't question me. She did, and a second later I flooded her mouth. I had forgotten to warn her, and she choked slightly, her eyes watering, before she quickly swallowed and pulled back. She wiped her face with the back of her hand, took a swig from her soda to wash away any evidence, and gave me a thumbs-up.
We scrambled upstairs, our feet skittering on the hardwood. Then I heard the second voice. Kim had brought a friend home with her.
Kat scrambled off to her room in a flash, and I headed into the kitchen to say hi and check out the situation.
"No, it's really no problem at all," she was saying to Kim's friend, Lisa. "She can absolutely stay for a few days. She can have Mark's room."
At the sound of my name, I appeared in the kitchen doorway. My mom saw me and her expression didn't change.
"There you are," she said, confirming the plan. "Lisa's going to be staying in your room for a few nights."
I let out a loud, theatrical groan. "Why? Can't she just share with Kim? Her room is big enough."
I knew damn well it wasn't. Kim's room was barely big enough for her and her clothes, but I played dumb, putting on my best wronged-son act.
My mom just stared at me, unimpressed. "You know it's not, Mark. You can either take the fold-out bed in the living room, or you can have the privacy of the basement. It has the spare bed down there."
Lisa looked mortified, her gaze fixed on the floor. I could see a blush creeping up her neck. I immediately put on a reassuring smile.
"It's fine, really," I said, trying to sound as magnanimous as possible. "The basement is fine. You are welcome to my room."
My mom gave a short, satisfied nod and turned back to the counter. As I turned to head for the basement stairs, I caught Lisa's eye for just a second. She offered a weak, grateful smile. I smiled back, feeling the wheels in my head start to spin. This was going to be interesting.
I left the kitchen.
“Hey,” Kat called out from the hallway. She looked apologetic. “Sorry about the inconvenience.”
“It’s fine,” I mumbled.
I went down to the basement, the silence of the room wrapping around me. I lay on the fold-out couch, staring at the ceiling, my mind racing.
The next day, Lisa properly introduced herself to me. She was hot, with great breasts, possibly a D-Cup. The way the loose t-shirt she wore stretched over them made it obvious. Fuck, I wanted to taste them. And fuck them. She was 19 like my sister, but there was something different about her.
And I was presented with a rare opportunity. I might get a chance to check out the hot body of a nineteen year old—how? That was the challenge… but boy, would I love to slide my dick between them.
The second night of her stay, I discovered Lisa was generally okay, even friendlier than my prudish sister. I watched her from the hallway, my heart pounding a little faster. It’s after midnight, everyone’s in their rooms, sleeping or watching TV if they had one. But Lisa was restless; she’d been moving around, and she thought everyone was asleep and she had the run of the place.
The kitchen light was on, cutting a sharp slice through the shadows of the hallway. I lingered in the dark, keeping out of sight but watching. She was wearing a tanktop that had been cut off right at the navel, the fabric riding high as she moved toward the kitchen, exposing the flat expanse of her stomach and the faint line of hip bones. No bra. The shorts she had on were scandalously short, barely grazing her thighs, and the way she walked suggested she wasn’t wearing panties either. My eyes tracked her, drinking in the sight, my mind already racing with possibilities.
I had gotten lucky a little earlier, overhearing enough of a conversation in the kitchen between Kim and Lisa to know she was struggling with insomnia. My mother sometimes struggled with insomnia, too. She kept a small arsenal in the cabinet in her bathroom—sleep aids, pills, bottles of NyQuil. I knew exactly where they were. I had a list of fantasies I wanted to live out, and this was the next one.
I approached the bathroom with care so no one would know I was outside. I opened the door, which as a blessing, ours is silent when opening. And from my vantage point, I could hear the spray of the shower. She was trying to relax herself. I could see the outline of her silhouette against the steamy glass. Water beaded and trickled down her skin, highlighting the curve of her breasts and the flare of her hips.
After being lost in my lust and the mesmerizing view of that silhouette, I slipped back out of the bathroom and into the hallway, my heart hammering against my ribs. I wanted to jerk right there in the hallway. My cock was already straining against the fabric of my boxers, a tight, aching knot of desire.
The game was on.
I walked into the kitchen, feigning a start as if I’d just woken up. I looked disoriented, rubbing my eyes, not looking around me, just scanning for her.
There she was. Lisa was sitting at the kitchen table, a half-eaten sandwich placed on a napkin beside her. She was reading a paperback, her head tilted, but when I turned and our eyes met, the air between us seemed to thicken.
"Hey, I’m thirsty," I said, my voice sounding casual, almost bored. I pulled open the refrigerator door, the light flooding my face as I pretended to search for a drink. "And you?"
Lisa blinked, the book lowering slightly. She looked exhausted. Her eyes were rimmed with red, and her posture was slumped.
"I can’t sleep!" she declared, the frustration clear in her voice. She put her book down and slumped back in her chair, running a hand through her damp hair.
She was so hot, especially with what she was wearing. She had grabbed one of Kim’s robes, but she hadn't bothered to tie it. It hung open, exposing a flash of skin and the curve of her thigh with every shift of her weight. I took a drink of orange juice, letting the cold liquid slide down my throat to cool the fire in my veins.
"I might be able to help, if you’re interested?"
I took the glass out of the fridge and poured myself another serving, keeping my eyes on hers. I wanted to see her reaction. Would she be desperate enough to take a kid’s help? She was clearly tired, the kind of bone-deep exhaustion that made her vulnerable.
"What you got?" she asked, her voice cracking. She tried to hide her enthusiasm for a chance at sleep, but she couldn't mask the desperate light in her eyes. She shifted in her chair, her legs crossing and uncrossing.
I put the glass down on the counter with a deliberate clink. "I’ll be right back!"
I grabbed the bottle of NyQuil and some generic sleep aid from the cabinet, mixed it quickly, and returned to the kitchen. Without letting Lisa see what I had, I poured it into a glass and presented it to her.
“What is it?” she asked, looking at the purple drink in the glass. She didn't seem suspicious. Just exhausted.
“Something my mom drinks. It knocks her out!” I said, almost ready to take it away, like I understood if she didn’t take it. I let out a long, exaggerated yawn and rubbed my face. "It’s strong stuff." And that closed the deal. She took the glass. "But don’t drink it until your back in bed. My mom swears by how effective it is."
I finished my juice and put the glass in the dishwasher.
“I hope it helps. Good night!” I disappeared back down the basement stairs.
“Good night Mark, and thanks for this!” she said with that beautiful smile.
Within ten minutes of taking this, Lisa would be out—hard, deep sleep for hours.
I waited thirty minutes. I needed to make sure the drug had enough time to kick in, enough to bypass her defenses. I checked the time on my phone, counting the seconds, listening to the house settle around me. Finally, I crept back up the stairs, my bare feet making no sound on the carpet. I moved like a ghost, through the hallway and to her door.
I knocked. No answer.
I opened it a crack. The room was bathed in moonlight filtering through the blinds. And there she was, out cold. She was sprawled across the bed, the duvet tangled around her legs, and to make life so much better, she slept nude. The moonlight caught the curve of her shoulder, the swell of her breasts, the pale line of her stomach. She looked like a fallen angel, innocent and utterly helpless.
I slipped inside and closed the door silently, locking it with a soft click. I walked to the bed and looked down at her. She was so beautiful, a vision of youth and perfection, and I couldn't resist.
I leaned over and kissed her. A slow, deliberate kiss on the corner of her mouth. She didn't stir. Little reaction, but that didn’t matter. I wasn’t here for a tender moment. Because of how heavy a sleep she was, I could finally try fucking her breasts.
I got naked then climbed onto the bed. I straddled her waist. I cupped her beautiful D-cups in my hands, squeezing gently, feeling the heat of her skin against my palms. Holding them together, I slipped my hard cock between them, the soft flesh molding around the shaft. I stroked in and out, the friction electric. It was everything I dreamed and hoped. Once I got the rhythm down, it felt amazing. I watched her face, searching for any sign of waking, but she was gone, lost in the drug-induced void. I came all over them, hot and sticky, the white fluid glistening in the moonlight.
But the sight of this amazing teen got me hard again so quickly. It was a revelation. Then I got brave. I knelt between her legs and opened them, revealing the dark triangle of her sex. I leaned down to her pussy, licking and sucking, tasting the salt of her tender lips. She got wet from my attention, her body responding on instinct. It was time for another fantasy to come true.
I rubbed the head of my cock up and down her pussy lips, teasing her, then pushed in. I fucked slow at first, savoring the tight grip, the heat, the fact that she was completely unaware. There was no sign of her waking. But she pursed her lips, it seemed like she was enjoying, somewhere deep in her sleep. I picked up the pace until I was slamming her exquisitely tight pussy. They would sporadically clamp on me, and then one after another happened, she was orgasming. I felt the cum around my cock as I thrust deep into her. The sound of our bodies slapping filled the silent room. I pulled out and came on her belly, the hot seed mixing with the sweat on her skin.
As I lay beside her, kissing her, sucking on her nipples, playing with those supple breasts, I felt a surge of adrenaline. It was long before I was hard again. I decided one last experiment—I manage to slide my cock into her mouth, coaxing her lips open. And... I nearly came just from what I was seeing happen, her sucking me in her sleep. So, slowing at first, I fucked her mouth. Then, gradually on instinct, I fucked her faster—not trying to go deepthroat. At that age I don’t think I had that length. But still, I didn’t want to try a gag reflex. Because of the sight of this, and how tight she’s sucking, it wasn’t too long before I was cumming in her mouth, a thick stream of cream that she swallowed reflexively, her throat working to gulp it down.
I lay there for a moment, catching my breath. I found the almost empty sleeping draught on the nightstand and poured what was left pooled at the bottom, into her mouth. On reflex, she drank it... I hoped that would be enough to wash out the taste of my cum.
Once I had gotten her covered again, I returned to the basement. I felt alive from the experience, my skin buzzed with the afterglow, and I was still horny. I wasn’t ready to sleep. But I knew what the cure was.
I decided to seek out Cat—and see if I could get some action there.
I snuck into her room, got naked, and slid under the sheets, and cuddled up to her. I started kissing her neck...
"Hmm, that feels amazing – you must be really horny.." She giggled half asleep. My hot fifteen year old sister was lying on her belly, and she just widened her legs. I took the invite, and positioned myself between them, sliding my hard cock in.
"Fuck me bro, you’re so hard… that’s it fill me.." she moaned into the pillow as I slid in deep, possibly rubbing her g-spot as I went. I felt the tremors of an orgasm ripple through her, she moaned loud into her pillow. I savoured long deep strokes, changing from tender to hard and back again frequently. I was slamming her pussy hard by the time I was ready to cum.
I pulled out and shot on her back. She grabbed a paper towel from her nightstand and gave it to me, cleaning her. I pulled her close, kissing her deeply, loving the feel of her tongue in my mouth. I stayed there for a long moment, holding her, before finally leaving.
