Ginger wakes up in her hut in the middle of the night, horny out of her mind as usual. She looks over and sees Mary Ann still asleep. What a little good girl she is.
Ginger could go over to the Professor's hut and fuck him again. Or she could slip into Gilligan and the Skipper's hut. Skipper can't see his dick, but it's there.. Hell, even the Mr. Howell can get that wrinkly old dick up sometimes.
No, this time she thinks she'll plow some new ground, as Mary Ann might say. Time to see what Gilligan's skinny dick feels like in her mouth.
