The second she was out the door, I slipped into my 18-year-old sister’s room for…uh personal reasons. I knew exactly what I was looking for, but what I found wasn’t what I expected.
Apparently, at college, she’d picked up a dog. A large dog. Now I was alone in a room with her. What could possibly go wrong?
Or right as the case might be. In full heat, she was exactly what I was looking for.

Damn, I love my sister, Becca. She was a very voluptuous, sexy 18-year-old who was just coming back from college for the weekend. I didn't know it at the time, but she was also bringing her German Shepherd, Trudy, with her.
Late that night after she'd gotten in and all the pleasantries had been said, Becca went out with some of her old friends for a bit of show around the town. That left mom and me alone. Once mom trundled off to bed, I snuck into Becca's room for a look-see and was instantly greeted by her dog.
"Good girl!" I patted the dog, who licked me. My heart was racing a million miles an hour as I thought about what I was doing. I locked the door, looked around and found her used panties sprawled out at the end of the bed.
I had not seen Becca since she'd went away to college, but I'd dreamt of her every night. I longed to hold her tight against my masculine body and show her what a good time really was.

I took off my clothes, laid back on her bed and lifted her lightly-scented panties to my nose, dreaming that I was sniffing the real thing. That my goddess of a sister was lying right next to me.
A few moments later, my dick getting hard, I felt a gentle, yet insistent, licking on my shaft.
"Not now, Trudy! Go away."
Thankfully, the licking stopped. I pressed my sister's aromatic, cum-filled panties harder to my nose and grabbed my cock.
The moment I did, Trudy pressed her muzzle to my mouth, pushing the panties inside.
"What are you doing, you stupid mutt!" I bolted up, the moment ruined.
That's when I saw it. Her extremely large, heat-filled pussy was on full display. Red and swollen, my cock jumped when I saw it. I gulped and started to say something, but the German Shepherd took advantage of it and stuck her tongue into my mouth.
"Yuck!" I tried to push her away, but she was nothing if not insistent.
Trudy's large frame pushed me back against the bed and in one, swift motion, she mounted her swollen cunt perfectly down upon my aching, throbbing cock.
Now that was one hell of a neat trick!
