With some nice, sloppy kisses!

You looked between the two, and as you did you thought of a good way to start things off. You begin using your slimy tentacles to stroke them off and caress their bodies while you brought them in close. You look at the Sea Serpent and decide that she'd be a good place to start.

You bring her face in close and begin kissing her. Your tongues fought for dominance, but due to your tentacles milking her cock you easily won, and could begin frenching her to your heart's content!

You make sure to do something with the Umi-Nyobo of course, shoving a tentacle in her mouth for her to suck and lick. She'd be enjoying the taste of your tentacle slime, or she'd be earning one right up the ass!
