I want to be the little algae girl, cleaning and drawing the bath in anticipation of my beloved fungus onee-sama. She would soon return, saying she brought the cooking ingredients and proceed to suddenly kiss me. For several minutes I'd drink her hot saliva, necessary for photosynthesis, while blushing profusely. Then she would say she's taking her share of food too, burying her face to my crotch and licking up the sweet polypeptides and polysaccharides I secrete for her.
After "dinner" and a bath, my forward and bold fungal onee-sama would have me pinned on the bed. Embrassed, I'd beg her to stop, but she'd just say "Ufufufufufu... " and continue, extending her haustorium and penetrating my cell wall. It'd hurt at first, but I'd bear it out of my love for her, and soon the permeability of my cell membrane would increase due to her secretions (such as usnic acid) and I would start to feel good, releasing even more sugars and vitamins for her growth until we are both tired. Then I'd sleep peacefully while she pats my head, secure in knowing that she'll be there for me. We'd live like this for centuries, never changing except for growing about 1mm per century (though that actually only holds for certain lichen growing in coldest regions of Antarctica).
