Chapter 4

Erotica Sex Story: Chapter 4 - He was masturbating into her underwear night after night—rubbing himself against the soft lace of her favorite pink bra, spilling thick ropes of cum across the crotch of her pale-blue panties, then carefully folding them back into her drawer so she’d unknowingly wear his mark against her most intimate skin the next day. The secret thrill of seeing her walk around the house in those same stained pieces, hips swaying, ass cheeks shifting under shorts, kept him hard and aching for more.

Monica Didi lay completely naked in front of me, and I was sitting between her legs. My heart was pounding. The moment I’d been waiting for so many years was now upon us. I could sense Didi had also held this moment in her heart for a long time.

My breathing was becoming heavy, and my penis was slowly inching closer to her sensitive center, just a few inches away. This proximity was enough to drive me crazy. Didi’s face flashed before my eyes, the same longing and anticipation evident in her eyes.

In that closeness, I asked in a low voice, “Didi ... can I do it?”

Although I knew she had already given her consent, I desperately wanted to hear her approval one last time. Didi looked me in the eye, smiled slightly, and nodded, permitting me again.

I paused for a moment. I couldn’t figure out what to do next. But my mind flashed back to all those nights when I’d secretly watched porn, each time imagining Didi’s face as a distraction. Gathering courage from that memory, I slowly touched my penis to her delicate area. Using just the tip, I began caressing her soft spot. That gentle touch sent a jolt of electricity through me. Didi, taking a deep breath, closed her eyes.

Slowly, I began rubbing my penis against her delicate clit. The gentle glide felt like it was tugging at my nerves. Every time my penis brushed against her wet slit, I felt my entire body shiver. I felt a warmth and sensation fill every nerve.

Didi’s eyes were closed, her lips were quivering slightly, and her face had taken on a distinct intoxication. Her breathing was getting faster, and each time I moved up and down, the tightening of her face told me she was feeling this touch deeply, too.

I gathered more courage and slowly increased my pace. My penis glided over her soft, wet lips. The warmth and moisture drove me crazy. I felt like I had entered another world.

Now and then, Didi would slightly raise her waist, as if trying to draw me in even deeper. Beads of sweat glistened at the corners of her eyes, and every movement on her face told me that this touch was as intoxicating to her as it was to me.

Then suddenly, Didi grabbed my waist and whispered under her breath, “Enough ... don’t tease me anymore ... put it in.” There was deep anxiety in her eyes and a soft moan on her lips. Her voice and urgency told me she couldn’t hold back any longer.

I was in a similar state. I couldn’t contain myself, but I still wanted to prolong the moment. This was a dream I’d had since childhood, when I first learned about sex. Whenever I thought of it, my older sister always came to mind. And now that dream was a reality.

I looked into her eyes with a slight smile and said softly, “Okay, Monica didi ... I am ready now.”

I slowly placed my penis against her cleavage and pushed it in with a gentle push. Her cleavage was incredibly tight, allowing my penis to slide in only slowly. I felt as if that warm, moist tightness was swallowing my entire body. Every millimeter of penetration sent shivers down my spine.

Didi closed her eyes and, pursing her lips, turned slightly on her side. Her face reflected both pain and pleasure. Her eyebrows were furrowed, but a soft moan escaped her lips. Her body twitched agonizingly on the bed, as if each thrust was deeply impacting her.

I slowly pushed my penis further in, each thrust driving me crazy. Didi’s breathing became heavier, and her face would sometimes wrinkle and sometimes relax. Her hands clenched the sheets, her entire body trembling with each thrust.

I slowly pushed deeper and deeper. The tightness was so intense that I began to lose my patience, and I tried to enter her with all my might. Then, suddenly, I felt something different—a strange wetness that wasn’t just any moisture. I bent down and saw that drops of blood were flowing from her private area.

The drops slowly dripped onto the bed, leaving red stains on the sheets. To my astonishment, my penis was now fully inside her, and with each movement, more blood flowed. Didi suddenly opened her eyes, a flash of pain crossing her face. Her scream echoed through the room.

“Ahhhh ... Golu ... It’s hurting so much ... stop it!” She moaned loudly and started pushing me away. Her hands were pushing hard against my chest, as if trying to push me back.

Tears welled up in her eyes, her lips quivered, and her entire body ached with pain. She repeatedly tried to pull back, but my cock remained lodged inside her. With every movement, she screamed, and her body trembled.

I was stunned. My heart was filled with joy at the fulfillment of my dream, but the sight of Didi’s agony before me made me drenched in sweat. Drops of blood continued to drip onto the bed, red stains spreading across the sheets.

She kept pushing me away, her voice cracking with pain, “Take it out ... Golu ... please ... it hurts a lot...”

Seeing her condition crippled my heart, but the grip and tightness of her penis were simultaneously driving me crazy. She repeatedly tried to pull herself back, and with each attempt, her entire body trembled wildly on the bed. Her screams and moans echoed throughout the room.

I immediately pulled my penis out of her and backed away from her body. Didi cried out in pain, pressing her head back into the pillow. I never knew sex could be so painful for her.

Hearing his groans and cries, deep regret and fear sank into my heart. I knelt beside him, gently caressing him with my hands, and thought to myself that I must care for him more.

Didi looked at me, pained and crying, and screamed, “Golu! Why didn’t you listen to me? Why didn’t you stop when I first told you to retire? Why did I have to endure this?” Her voice was a mix of anger, pain, and despair. Tears flowed from her eyes constantly, and her body was shaking every second.

Then Didi picked up her scattered clothes from the bed and, weeping, walked towards her room, holding her waist. I wanted to see her from behind, to go and hold her hand or caress her, but I knew she didn’t want me near her anymore. Her crying and anger told me that distance was right for her. I remained sitting in my place, silently looking towards her room, filled with both regret and worry.

That was Monica didi, and it was my first attempt to get to know each other, but everything didn’t turn out the way I wanted.

The next morning, I woke very early. There was a faint light outside, and the house was eerily quiet. I slowly glanced towards her room. The door was half open, and inside, Monica Didi was still fast asleep. Perhaps she had taken leave from work. Despite her tiredness, a strange, calm smile crossed her face, which made me pause.

I suddenly felt very sorry for them. I felt I had to do something for them. I remembered that chocolate is the best solace in such pain and fatigue. I immediately decided to leave. When I arrived at the building, I noticed that the surrounding shops were closed. But I was determined. I slowly started moving forward on the road. After walking for about a kilometer, I finally found a small shop open, where I bought some chocolate and then returned.
