You found a mate at a bar. Guiding her to the bathroom for sex was easy, she was rather drunk. In the empty room, you jammed the door shut, tore off her clothes, got her down on all fours and changed to your true form, as your cock emerged and stood to attention.
You entered her and began slowly thrusting, eliciting soft moans as the tip of your massive cock entered and exited her moist pussy. Her form changed, giving her violet eyes, fangs, and silver hair-fur. Her cock grew in next, and emerged and grew erect as you began to ease in your huge length, making her moan louder. You growled low as your human mate thrusted her hips towards you, inching your thick prick further in. You couldn't handle the shallow fucking anymore, and you pulled back until you were almost out of her before slamming in all 16 inches of your canine cock, making her scream, her pussy already reshaped to hold it. You thrusted as hard and fast as you could, stretching her to her limit and making her howl in mad pleasure and lust. Her pussy milked your cock, causing intense pleasure. The two of you howled in lust together, huge cock thrusting into wet pussy.
Finally, her pussy convulsed wildly and she screamed, cumming hard on your cock and transforming fully into a shemale winged dire wolf as you filled her womb with eggs.
