You reach under the gorilla, tugging at his fat nipples with one hand while your other goes to his thick, throbbing cock. You micro-fuck your knot in and out of the hairy ass in front of you, huge latex wolf-nuts pulsing against the ape man's taint. The pair of you spoon for a while on the cool evening grass, grinding your sweat-covered, beastial latex bodies against each other as your massive orgasm dies down. The last of your potent wolf cum pumping deep into your new mate's gut.
As you spoon, you instinctively flex your muscles. It feels like your whole body is inflating with muscle once more; only this time the change is subtler, and a bit slower. You gain a few inches in height, and your hands in feet seem to almost double in size. Your biceps swell, to bigger than a human bodybuilder's calves, and though you can't see it you can feel corded muscle of proportional size sweep down you back and lower body. The muscles on your ass become especially thick and juicy. Your chest swells out even larger, your pecs so strong and thick now.
You feel your cock throbbing large and longer in the muscle-ape's butt with each of your final gushes of wolf cum. Your nuts twice as big and heavy, rolling over your thighs and into the cool grass. The already thick tufts of rubber fur on your chest, pits, taint and crotch puff out into even denser forests of manly fur.
The gorilla rotates himself around your swollen knot, throwing his corded calves around your waist. Grinning, you lean forward to kiss the studly gorilla, making out sloppily. You grind your hairy pecs together, his cum-inflated gut rubbing against your washboard abs. His rock-hard cock leaking pre all over both of your lower abs and upper thighs as he humps needily into your embrace.
Slowly, you drag your still swollen knot out of his ass, chewing on his tongue. He moans into your kiss, his asshole flexing around your shaft. You pull halfway out, letting his ass muscles flutter in relief against the much thinner, tapered length of your wolfhood, before you thrust back in roughly. You hilt yourself in him, knot and all.
The submissive muscle ape throws his head back, breaking the slobbery kiss to bellow in pleasure as his cock explodes over you. His cum shooting up in between your pecs, and coating both of your muscle torsos in rubber white gorilla cum.
You make out once more, knot fucking his abused ass and grinding your cum-slicked latex bodies against one another. The air around you heavy with filthy beast-men sex. The two of you bask in the afterglow, as...
