Your Boyfriend Is A Werewolf Who's Terrified Of Accidentally Hurting You, So He'll Only Ever Fuck You

Your boyfriend is a werewolf who's terrified of accidentally hurting you, so he'll only ever fuck you when he's in his human form. It's indistinguishable from a normal human except he has sharp teeth and his cock has a knot, albeit much smaller than normal. You don't really mind because he's gorgeous (for a human) and the sex is amazing.

Eventually though he forgets it's a full moon and transforms while he's fucking you. One minute he's gently pushing into your ass, the next his cock suddenly expands inside you to about twice its usual size. You cry out in shock as he goes absolutely crazy, emitting feral growls into your ear before dragging his tongue across your neck. Then he bites your shoulder and sinks his teeth in. Your cock twitches and spurts precum onto the mattress. When he tastes your blood, he loses it and ruts into you harder than he ever has before, his gigantic knot stretching you to your limit. His clawed hands find yours and squeeze them reassuringly to let you know that he's not trying to hurt you, but when his orgasm hits he speeds up again and you can't help screaming.

When he hits your prostate, you pass out and sleep for the rest of the night. In the morning you wake up to find a bandage on your shoulder and your boyfriend in human form again, kissing you gently and apologising for hurting you. You tell him not to worry, you want to do it again tonight.

"You're such a beast, darling, I love it...please?"

He blushes and transforms again. Your jaw drops, you didn't know until now that he could transform at will. He pounces before you can react further and starts to force himself into your ass again. You don't believe it'll fit - it's too big, Jesus Christ, it hurts - but still wrap your legs around his furry torso, pulling him in closer. You mentally swear that you'll keep fucking him until his size stops hurting. He growls and pants from the effort of getting it in, his tail wagging as he drools all over you.

Involuntarily, your ass cheeks clench together, your body trying to reject his knot - against the will of your brain - but it's no use. With a final particularly hard thrust, he pushes the knot inside your sore hole and lets out a howl of triumph. Despite how much you desperately want him to keep going, tears begin running down your cheeks from the pain. He notices and bends down to lick your face, covering you in his drool. Through your cries of pain - and pleasure - you wrap your arms around his neck and kiss the tip of his snout.

"Fuck! I love you so much..."

He hears that and roars, slamming into you so hard you cum immediately. You assume that means he loves you too.

He doesn't stop.

Hours later, you cum for what feels like the hundredth time. All you can produce is a tiny trickle of semen due to multiple previous orgasms, the drying remnants of which cling to your boyfriend's fur. He howls again before he finally cums, his knot swelling up to its full size.

You both know you're gonna be doing this a lot more.
