The Zoologists/Lisa licks her sisters pussy and dog dick

Lisa stares for a bit at the cock buried deep in her sister. She pokes out her tongue and licks from the top of her sisters pussy down to the balls of the dog. She does it a few times as the flavor was so strange but so delicious.

Every time her tongue does this, her sister shudders from the pleasure.

All of a sudden the dogs dick pops out and Lisa's face is covered in a mixture of both her sisters and the dogs cum.

She:

• Scoops all she can into her mouth
• Wipes it off her face
• Turns around and kisses her sister
