It seems you need to put your feelings for your best friend Ellie away. She just doesn't see you that way. You stand absolutely no chance. Never will you date her or be physically intimate. However, she does sympathize with your struggle and will toss you a pity...well, not fuck, of course not, but jerk off encouragement session? She truly is a kind and caring friend. You'll be allowed to masturbate with her as an outlet for your lust. And if you keep being a useful friend that completes tasks for her and doesn’t act like a cringy unrequited love stereotype you can keep having this occasionally. Think you can handle it? Maybe if you time it right you can both climax at the same exact time. See? The friend zone isn't THAT bad, is it?
