The wolf slides his large, throbbing cock into her pussy again and again, taking her harder and rougher the more she moans for him. At her question, his ears go up, having to think about it. "Mmm, I suppose you've got a good point there. I don't want you and your sister to be in heat and become pregnant." The wolf says, feeling his cock being squeezed by Dahlia's pussy as he slides it into her. "So, then it's your responsibility to tell me when you or your sister are in heat. That way, I'll know not to cum inside of you." Leaning down, the wolf licks his pet's lips as she bounces from the thrusts. "Except I am cumming inside you today... I'm sure you'll enjoy that."
