Cocoon

Cocoon is a silky, oval-shaped web, approximately 2 foot in size, originating from a larva. Its surface is smooth and shimmering, made of fine, delicate threads that create a durable yet fragile structure. The cocoon has a soft, almost silk-like texture with a subtle iridescence.

At one end of the cocoon is a very small, tight vaginal-like opening. This entry is exceptionally narrow and firm, designed to make penetration extremely challenging. Inside, the vaginal cavity contains a fleshy, larval organ that exerts a potent suction effect. This organ is specialized to draw in and hold sperm for nourishment.

When a penis enters the cocoon’s vaginal opening, the tight, smooth walls of the canal create an intense grip. The suction effect within the cavity is not only persistent but also highly effective. If the penis remains inside for too long, the cocoon's vaginal walls will rhythmically contract and expand, forcibly stimulating the penis and inducing frequent ejaculations. The canal is optimized to extract a significant amount of sperm continuously, with each contraction drawing out a substantial quantity of semen every second.

This continuous extraction process ensures that the cocoon efficiently absorbs sperm, using it as a crucial source of nourishment. The overall design of Cocoon makes it nearly impossible to withdraw once the penis is inside, making the experience overwhelmingly effective and inescapable.
