You begin pushing your cock against it...your cock going remarkably further into the sheath than you expect...but near the end there is a tightness...or rather that you have been pushing the whole time against it.
"OOghhh" you groan as the creature pants...as you grope each other...your pale smooth human flesh gripping and pulling at is powerful muscled furred frame.
"yourrr soo good" I purr-growls in your ear as it humps harder...you feel more of your shaft now in the sheath of it as it humps back pushing you against the wall. "I'm going to want you all the time..."
It grunts...your fingers feeling silky fur...your skin so sensitive to it... your cock seeming to be as aroused as ever as you feel the hot electric shaking going back into your whole body...
One of his legs shifting between yours as you both fuck his sheath...your cock seeming deeper in it now...almost up to your balls.
"Yesss...Yerrsss...sooocose..." The fox man grunts as he fucks back in a way that makes you think for a moment that he is getting more male rather than less.
"Ooghh gogdds...." you grunt the head of your cock so super-sensitive and hot.... kissing the head of his cock as you both are rutting against the wall.
But something seems to be wrong
