A little resistance.

As you grab your cocks with a single tentacles and line it up with the sea serpents hot awaiting pussy lips, you feel the umi-nyobo actually attempts to spit out a tentacle, gagging and retching as your appendage attempts to stay in. That wouldn't do, so you follow through on a mental promise and sneakily maneuver a tentacle towards her quivering ass. She gasped and whimpered as your tentacle probed her, making cum a copious amount from the sudden entry and writhing in her anal linings with sloppy wet noises. The way she was going limp made it clear she was starting to understand the situation.

You frenched the sea serpent's mouth, barely giving her a chance for air as you toppled her, bringing down your heavy breasts on hers. They rippled, jiggled, and smushed together as you hips slapped against hers, you bodies pressed so closed together that it looked you were trying to meld. Her cock splattered and squirted on your taut belly as you pounded her tight, moist pussy. Her growls slowly turned into whimpers as her resistance broke down alongside her former masters.

Once you filled her pussy, you'd do the same to her master while tentacles in her ass. Speaking of asses, your snakes, who occasionally licked you, each other, and even the monster under you, managed to keep tabs on the elf harem while you went to work.
