A young Chagrian female

Rowol is sitting on his bed. Next to him sits a girl. A purple skinned chagrian. And she is kissing him.
Chagrians closely resemble twi’lek’s. They too have two fleshy tails coming from the back of their heads instead of hair. Except chagrian head tails are thicker, shorter and tipped with thin horns.
“Mmmh, Rowol.” The chagrian girl moans while kissing Rowol.
“Ah, Diah.” Rowol moans back.
Diah? You’ve heard that name before. Rowol often told you about a friend at school named Diah. You always thought his friend was a guy but no. Looks like he had a girlfriend all along. And it looks like you caught them just as they are ready to take the next step.
