A trip to a park

It was late at night as the two sister flew to the park. Blackfire was excited and Starfire was nervous but excited as well. They landed in the park, no one else was around. Blackfire was wearing a black bodice, which showed off her cleavage. A black and silver leather jacket, a very short black mini skirt, fingerless gloves, silver thigh high stockings and high heel boots. Starfire on the other hand was wearing much less, she was only wearing the collar and a short tan trench coat.

" Are you sure about this sister ?" Asked Starfire blushing, as she was embarrassed.

" Yes sister, you where all in back at the tower." Said Blackfire, smirking.

" But that was back home, this is in public." Said Starfire, as she looked around.

" Starfire, there's no one else around." Said Blackfire, smiling.

Starfire gulped, " I'm sorry sister, but I feel embarrass about this." Said Starfire, looking around.

" Don't worry sister, I wouldn't do thing that would hurt you. I just want us to bond like sisters." Said Blackfire, smiling.

" Now, take off the coat." Said Blackfire, smiling.

Starfire gulped, as she did as she was told. She let the cost slid off her body, realizing that she was completely naked underneath. Blackfire took a few moment to look over her sister body. Her slender figute, her massive breasts, lucious legs and shaved pussy.

" Now put this on." Said Blackfire, as she pulled out a dog ear headband from a bog.

Starfire put it on, then Blackfire went behind her sister and groped her ass. This earn a moan from Starfire, then she pulled out a dog tail but plug and shoved it into her ass.

" Now, on all fours." Said Blackfire, grinning.

Starfire nodded, as she did. Then Blackfire pulled out a leash and attached it to Starfire's collar.

" Now time for a walk." Said Blackfire, smiling.
