Jake tries to help Finn with his erection problem, but playing video games doesn’t help him, and he already masturbated 10 times and nothing changed, so Jake tells him to try something else and takes him to see the sweet princess. Finn, embarrassed, doesn’t want to but Jake takes him anyway, when he arrives he shows “the problem” to the sweet princess.

When she sees him she decides to help him and prepare a potion because if she doesn’t do something about it she could die and tells Jake that he must go to get some ingredients, he hurries and runs away. When they are finally alone the sweet princess goes, changes and tells Finn to get ready, because she is going to help him. She puts on a rather revealing outfit and starts touching Finn, he asks her what she is doing but the sweet princess tells him not to talk, as she knows how to solve erection problems.

She takes Finn’s huge cock and starts to masturbate him with her huge breasts and then she sucks him off, and just at that moment he squirts without holding back bathing the sweet princess in cum, but in spite of that, Finn is still hard, so the sweet princess decides to get on top of him so he can penetrate her.

Then Marceline arrives and looks at both of them. She tries to help the sweet princess to get out of Finn’s cock since it got stuck but it doesn’t come out, but the movement caused Finn to cum again and his cum comes out of the sweet princess’s mouth and also ends up inside Marceline.

The sweet princess manages to come out but Finn is still quite aroused and seeing Marceline he shoves his huge cock in her mouth until he cums inside her again and finally Finn feels better.

Just then Jake arrives and seeing that Finn is feeling better he decides to take him to more girls so they can keep doing it and his cock keeps getting smaller since he is still a little hard.
