Yes.

Unable to escape the domineering pony or the perverted grass, your mind slowly breaks as the reality of your situation sinks in.

You can feel each orgasmic release of the pony herm inside your very core, its seed tainting and corrupting your own body. Against your will your own ass forms ridges and little knobs for the pony's enjoyment, further increasing her libido.

Melting into you further, you eventually feel the pony cease all movement. Her huge breasts have melted to wrap fully around your chest, one of her hands has formed a sheath over your cock. Each orgasm you give her she greedily sucks it up.

Her cock never stops though and your ass remains tight and forever sucks upon it.

Before long you are both one large lump of solidified, quivering latex, forever bound in an orgasmic heaven/hell to each other.
