“I squinted through the big window, a portal to another world, trying to get a better view of the primal love scene before us. All I could see was a mass of wriggling fur and finger-like toes until my eyes focused in on one male and two females kissing, ear-tonguing and giving each other enthusiastic oral sex, punctuated with occasional somersaults, smacks and nibbles on fruit and leaves. Sometimes they interacted as a threesome. Other times, two would cavort together, while the third played with herself, alternating between fingering and using a red rubber ball as a kind of sex toy, rubbing and bouncing it vigorously against her large pink vulva.”
