Mansion/Go pet the dog
You walk towards the dog and then pet it. You see that it is a female dog. You still happen to be naked. Suddenly as you pet her she moves to your crotch, sniffing it. It has already hardened your penis. She then starts to lick it which makes you giggle a little. Then suddenly the dog starts sucking on your throbbing cock. You moan more than you ever have. She is sucking it hard as she circles her tongue around your cock. "Ohhhhhhhh, doggie," you moan.
You start to thrust in and out of her mouth. She sucks you for about five minutes and then turns around sticking her rear in your direction. You don’t have a single clue on what she wants. She seems to be putting it in the direction of your penis. With your penis still hard you notice her vagina moving a bit. You are curious as you should stick your 5-year-old dick in. You think and then go for it. You stick it right in as you feel the greatest feeling you have ever felt. You thrust in and out of the dog's pussy hearing her whine a little, but you keep on going. You go so much that eventually, you feel like something is leaving your penis. It felt like you were peeing. You had just experienced your first orgasm. You pull it out revealing a clear goo dripping down from your penis. The dog licks it up again causing you to squeal a bit and then leaves.
