1. Lots of sperm covering my latex encased body, or having to wade through a pool of hip high cum, etc...
2. Slime, lots of slime. Aphrodisia slime is best!
3. Latex bondage.
4. Forced lesbianism.
5. Forced to use sex toys, like a squirting Sybian
6. Being groped and masturbated on by a group of rubber men.
7. Slimy tentacled lust monsters, and soft sexual vore.
8. Having to shimmy through a really tight corridor whose walls are made of groping hands, of slimy tentacles.
9. Being in a situation where you end up getting pressed up against one of the other sisters and things get sexual. (see 4) Maybe some latex bondage for two?
10. Room full of limp rubber cocks mounted on the walls and ceiling, and you have to get them hard and get them to ejaculate through handjobs and literal fucking.
11. Swimming underwater in a pool full of lusty jelly fish.
12. Each of the sisters getting paired up with a rubber man to accomplish a task, but things get sexual (forced or otherwise). For example, if the man coupled with the sister is given an overdose of "Super Hyper Sperm Max", then it's only a matter of time before he loses control of himself. So each sisters gets paired up with a man, and the two have to accomplish some task together, but as time wears on, the man has a harder time controlling himself. At some point, he will lose control and take the sister and have some messy wild monkey sex with her ;-)
