You bury your muzzle into Red's crotch, and breath deeply. You start to nibble at her pants, to where you finally have a good grip on her pants and start pulling them down. Doing so you get the smell of Red's intoxicating musk even stronger. Red notices what it is you are doing. Oh you naughty boy, she declares. What's happening to me, why do I feel funny? She asks. By the even stronger musk coming from her, you realize she is getting wet. This is driving you mad with lust, as your overfull balls are demanding release. You can see a wet spot forming in her panties, and begin to nibble on them. You find her taste to be intoxicating. You get a firm grip on her panties, pull on them hard, and hear a very satisfying sound of ripping material. Now you pull her panties free from her. You love the taste of her panties, but want to try the source of the wonderful flavor. You drop your head into her womanhood once again, this time with nothing in the way. You plunge your equine tongue into her wet folds. Doing so you hear her squeal with pleasure. Oh, that feels nice, don't stop, demands. This drives you to move even closer to her and to line up your massive equine cock and heavy overfull balls with her face. You leak some precum onto her face and down her front. She is initially shocked by this, then she starts to lick it off of her face. What is this? It tastes good, she says. She starts to lick at the flat head of your equine cock. This finally sends you over the edge, as you release torrents of human and equine cum into her mouth. With your release comes a loud whinny. Red tried to swallow a lot of it but ended up wearing most of it.
