A Lone Selkie!

Your eyes locked on a rather lost looking woman. She seemed to just be a futa human. She had long blonde hair, massive breasts that were just as big as yours, a thick and juicy looking ass that made your serpent hair hiss with envy, and a long, sixteen inch futa cock with massive balls.

You wanted to drink her cum, and in return fill her pussy with your own. So you emerge fully from the depths and begin moving towards the sexy futa on the beach, smiling lewdly.

She notices you, and seems paralyzed by indecision or fear. Using the oppurtunity, you rush forward and swarm her cock with your tentacles. The tentacle slime provided great lubricant for your fast stroking, and your free tentacles play with her ass and tits.
