Ok fine, here's the thing that didn't happen

WARNING: SMUT

As evening fell, the room bathed in the soft glow of the setting sun, Gummy felt a sense of peace. Despite the unexpected turns the day had taken, she was grateful to have found Yuri. They might not have had the most conventional start, but she was determined to be the best big sister she could be.

Nearing bedtime, Gummy decided to give Yuri a bath. She took off her clothes and his and went into the bathroom, helping Yuri wash himself.

As Gummy turned her back, Yuri noticed Gummy's body, her soft skin, her large breasts, and curvy proportions, his dick gets hard at the sight of his sister's naked body. Gummy had filled out well in the years following the Chernobog incident.

Gummy turned her head, catching a glimpse of Yuri's enormous erect shaft. Her eyes widened, and a mischievous smile played on her lips. "Well, well, looks like someone's excited," she purred, reaching back to stroke his length gently.

A naughty glint sparkled in Gummy's eyes as she stepped closer to Yuri, pressing her backside against his growing erection. "Okay, little brother," she cooed, reaching for the shower gel. "Big sis is going to teach you a lesson you'll never forget."

Squeezing a generous amount of gel onto her hands, Gummy began to lather up Yuri's chest, rubbing and massaging his body with her soft palms. She moaned appreciatively, running her hands down his stomach and then lower, cupping his growing balls gently. "My, my, little brother, you certainly are developing quite nicely."

Yuri's breath hitched as her nimble fingers explored his most sensitive areas. "Big sis," he grunted, subconsciously thrusting his hips slightly. "I'm feeling a little weird…"

Gummy giggled again, turning slightly so that her ample breasts were pressed against his chest. She whispered seductively, "Well then, let's continue your education." Reaching between their bodies, she guided his thick cock towards her entrance, teasing herself with the tip before slowly lowering herself onto his length.

They both moaned loudly as Gummy sank down onto Yuri's shaft, her warm walls enveloping him inch by delicious inch. Her eyes rolled back slightly as she took him in, the water from the shower now mixing with the sweat on their bodies. "God, Yuri, you feel so good inside me," she panted, beginning to ride him slowly. "Big sis is gonna make you cum so hard."

Gummy guided his hands to her hips as she rode him with increasing speed and intensity. The sound of their pounding flesh echoed off the bathroom walls, mixing with their increasingly louder moans and grunts. "Big sis... feels so good," Yuri gasped, his eyes locked on the sight of his cock disappearing into her again and again. "Your pussy feels amazing, sis."

"You like my tight pussy, don't you, little brother?" Gummy teased, her hands bracing against the shower wall as she bounced vigorously on his shaft. "You want to fill me up with your hot cum?"

Yuri only nods, his body tensing as he neared his peak.

Gummy cried out, her nails digging into Yuri's shoulders as her own orgasm approached. "Yes, little brother! Cum for me! Show me what a good student you are!"

With a roar, Yuri came hard, his eyes rolling back in his head as his cock pulsated deep inside Gummy's dripping wet hole. Rope after rope of hot cum flooded her, their mixed juices running down his shaft and onto her thighs. Gummy followed suit, crying out Yuri's name as her walls clenched and pulsed around him, milking his spent cock for every last drop.
