Michelle could feel the tiny piece of tentacle still inside her, writhing around her vagina. She moaned and shivered. She could feel her snatch filling up until suddenly a wet, suckered arm wrapped itself around her thigh. Michelle looked down, dismayed to see that her efforts had been for nothing, the red tentacle as strong and long as ever.
But then, she felt another wriggling sensation and watched in horror as a second tentacle wrapped around her other thigh. The two, foot-long appendages gently squeezed her thighs, sending pulses of lust down her body. Her hands dug into the soil and she threw her head back, her tentacles like clits, so sensitive against her colder skin. One hand crept down to finger the rest of her pussy, and she found one of the red tentacles join it, plunging into the depths to stimulate where she couldn't reach. Michelle groaned, eyes rolling back in her head until she came with a shriek, flooding the grass with her cum.
As her orgasm faded, she caught sight of the knife, glinting in the moonlight. She had an idea. Stretching out her tentacles again, she sucked in a breath and brought the blade down hard. Two more writhing ends joined the first on the grass, as the stubs retracted into herself. A few moments passed, and slowly, four new tentacles crept out from her vagina, slick and wet. Michelle nearly cried as she stroked her hands down their muscled lengths, for the pleasure, mostly, but also for the fact she would never be a 'normal' person again. Still, would she even want to be, with the incredible sensations her new appendages gave her? She could already feel her pussy quivering, wet and waiting for the next round.
With her tentacles slick and ready for pleasure, she knew she'd be in for a long, fantastic night.
