Your teenage daughter confides in you that she thinks she's ready to lose her virginity. All the other girls at school are losing theirs and she doesn't want to feel like she's being left behind. The only problem is that she doesn't like any of the boys at school - and she doesn't want to have her first time be with someone who doesn't love her. "I'm asking you for advice because I trust you and I know you know what's best for me daddy!" you tell her there are other options, and gently suggest that she could fuck the dog instead. She's shocked "are you sure that's okay to do daddy?" You explain the pros and she quickly warms up to the idea (she won't get pregnant, her doggy loves her very much, and it will be good practice for when she's ready to try with a boy). She asks you to help her because she has no idea what she's doing, and you supervise her to make sure the dog doesn't hurt her. You start by getting her to suck the dogs dick and have him eat her pussy (she shyly admits she had the dog lick her pussy before "once or twice") He is very well hung, and her tiny virgin teen pussy is slowly stretched open to take the entirety of his knot. She moans and gasps as he begins to hump her fast and hard. Your daughter cums as she feels the doggy's huge hot load shooting deep inside of her. She calls you for help because the dog is "stuck" inside of her, and when she finally gets him out his gigantic load comes pouring out of her newly deflowered pussy.
