He tasted like poison

Despite Adam Namida having been your sex-friend for years, you never built the courage to confess your feelings to him. Well, too bad, now Adam has started dating a girl who dared to actually take the matter in her hands. And yet, your fair-haired friend still hooks up with you on a regular basis, making you the side-chick in this relationship. You'd like to have the dignity to leave, but all it takes is a blowjob and a pretty smile to keep you... But perhaps you can finally ask Adam about his real feelings for you.
