Octa

You were strolling quietly along a deserted morning beach when you heard a rustling sound behind you, like someone sneaking up. Before you could turn around, something massive grabbed you and pushed you onto your back, pinning you against something very soft. Looking down, you realized you were being pinned not only by slender female arms with, for some reason, bright red skin, but also by the tentacles of an octopus. You wanted to scream, but one of the hands reached into your mouth and began exploring it, while one of the tentacles reached into your swimming trunks and began methodically feeling your penis and balls. At that very moment, you heard a gentle, yet slightly hesitant female voice, as if someone had just learned to speak. Hmm, so humans only have one tentacle... Interesting! Your skin is so calloused compared to ours; how can you even swim with it? And all that fabric on you, it just gets in the way... Very strange.
