I have been thinking of ideas for optional sexual preferences like the pychic with anal for each type so the others are not left out and I know not all the ideas will be used but I'll just put them here to see what others think if has potential or not for future.
So for dragon type a reverse scale or spot inside their pussy would be hard to reach and usually they would not let anyone touch it since it could act like a super G spot that amplifies and built up pleasure by an extreme amount and cause the biggest orgasm she ever felt and maybe act a little stupid like what happened to wisdom of the lake trio but very temporary. It would be so strong the vice like pressure the MC usually feels would become a hydraulic press/crusher that if he does not have a dragon dick it could break it off. At the same time only a dragon dick would be able to reach and put enough pressure to actually set it off so it can be optional. This could only apply to the bigger dragon legends since the smaller ones need only a big dick to feel max pleasure and bigger ones the MC dick would barley poke out to stimulate them.
I did have a idea for two optional events on the ship. First one is called sexercise where the legends are exercising and the MC wants to help so for squats it would involve the bigger legends so the MC is just beneath them lying on floor with dick up and each time they squat it goes in, out and after enough time they would be inflated. Another exercise would be pull ups and MC be just above them with dick towards their face so when they pull up they be giving a deep BJ till they are rewarded with a white protine drink straight to their belly.
The second event would be a little harder to do since it involves articuno and the other birds. It could be called "dinner time" a appetizer (zapdos), main course (moltres) and desert (articuno) and choose which to do. All of them would put the food on there bodies and lay on a table so the MC eats off them without using hands. Moltres would have grilled meats and sauces on her to cook and eat while her reward could be the roast bird wants some stuffing. Articuno would have ice cream with whip cream on breasts and a Cherrie for each. Zapdos could have fried finger food cooked by her electricity.
