Juicy alien girls asses and anal are mandatory.
and on this I thank you very much, as said above a double anal penetration would be very welcome, maybe even a system that the more cocks he takes in the ass, the wider it becomes like a gaping, to the point of having to put a plug in his ass, the bigger the gaping the more he has to use a bigger plug, otherwise he loses it on the road because it came out, (these are just ideas) potion to make it return to normal, which also lowers the perversion, or so many days without doing it makes it return to normal, (ideas) with this implementation of the plug there would be full of sperm, 1) empty intestine, 2) full intestine, 3) very full intestine (the capacity increases with this level), with this implementation when you are full, if you have the plug inserted, nothing comes out, but you need to empty yourself, or in the bathroom, or if you are gaping without a plug, the scene comes out by mistake, or if caught a friend helps you to make it come out with fisting or toys, or he likes to shower himself with sperm and pays you, or you collect it to create aphrodisiac potions or similar, my seranza and use them to give a penis to a girl, with relative alternative that with the right potion the dick becomes bigger or double, potions for bigger asses or bigger tits, or a mushroom that makes such much smaller so an average dick for her becomes huge, I say potions but it could be machinery, we are in a futuristic science fiction world after all, not knowing the story of the adventure, if such always uses the same ship to travel, 1) the monsters (animals) that he finds if he captures them and brings them to the ship it would be a zoo of perverted sex, every now and then they escape from the cages, 2) that by making more trips some insects infest the ship and if it is not eradicated every time the infestation becomes bigger and bigger bringing greater sex scenes, like the shower, but in more beds, around the ship, sometimes it happens that members of the crew are involved, and if you are perverse you join them. these are just ideas, but I hope they are useful xP. it would be nice too, she finds toys and brings them to the cabin, and casually sometimes (if a partner is a slut) she takes them without asking and discovers them, depending on the domination, or the partner who uses them on her, or to use them and such, to teach him not to use his stuff. I'll stop here, I hope I've been helpful and thanks for the work done so far.
