The young girl's mind is absolutely reeling in pleasure now, completely scrambled from experiencing cumming from her absolutely massive 15 foot horsecock. Her vision is blurry and cross, panting heavily as she feels her heart beat hard, which also made her cock throb with every beat. Erika's free hand softly rubs along the side of her cock, the pure animalistic fuckstick spurted a fresh stream of precum into the air, which fell into the cum pool that drenched most of her balls and cock. Erika shuddered and slips her hands away as she's too stimulated to properly move. No human could possibly feel the orgasmic bliss she was feeling, and it caused her to just blank out for a moment.
But not too long afterwards, her head perks up as she heard lots of voices and car noises outside, oh gosh! She panics, knowing that everyone is going to absolutely freak out, if they weren't already, she notices lots of damage in the house already...she lifts the salve up, knowing what she must do. She untwists the spray nozzle and splashes the rest of the salve all over the base of her horsecock, which drips down her balls and into the cum below.
A split moment after the salve hits her cock, she screams out in pleasure. Her already huge horse package explodes in size! She experienced an absolutely mind shattering and warping orgasm of unthinkable intensity! More pleasurable than the combined bliss of every human orgasm that has ever existed! Her cock erupts in a jet stream of cum as it skyrocketed in length! One of her balls crushes the town she lived in, while the other ball crushes the next town over. The growing didn't stop there as Erika could only stare forward as her cock became dozens of kilometres in length in mere seconds with absolutely no stopping. Her horsetip flared up completely, pumping out millions of litres of horsecum from her wide urethra hole onto the planet every second.
Erika screamed again in pleasure as her cock length passes one thousand kilometres in length as she has an earth-shattering orgasm, literally! She felt the ground shift under her absolutely massive, country sized horsenuts, causing incredible damage underneath, imprinting a massive crater on the planet's crust. Her cum shoots off in the atmosphere, which rains down on another part of the planet. The volume of cum increased as well, creating massive floods as the cum mixes with all the water, seeping down into the planet's core to extinguish its hidden fire. She can't see much past her cock and balls, but she can tell her body is still resting on her balls, and have enlarged so her body was high in the sky, her cock cumming every moment still. Her growth has been extremely fast, most victims down on the planet didn't even know they were going to be crushed by an 11 year old with continent sized balls, or drown in just one tiny drop that can flood an entire village with the most virile sperm imaginable.
Erika's body now enters space and her two leathery balls are bigger than the planet itself. She can see how far away her view was, and how absolutely massive she is, groaning as she feels herself stretch and grow more. Erika starts sobbing as her home planet becomes smaller and smaller. She can feel the planet bulge and strain under her orbs. Her pussy ached for some reason, burning with hot desire. She desperately scoops up her horse cum with her left hand and reaches back, shoving her own cum into her still human snatch. She rubs her cock with her other hand, and when she does, she quickly gets overwhelmed as she nears orgasm again. Her nuts contract as they squeeze around the planet with a massive CRUNCH noise. Erika screams again, crying at the same time as she knew she snuffed her home planet, her friends and family, she was all that was left, and her other-worldly shaft. She came hard again into the new void of space as she starts her life as a celestial body of horsecock.
