As usual, I finished work and headed home. My daily routine had become monotonous, so I decided to go to an izakaya alone for the first time in ages. Then, from behind, my junior colleague appeared!! “Senpai... would you like to grab dinner together?” After dinner, we'd get all lovey-dovey and have sex at my place... but actually, she's a succubus who wants to control my ejaculation?? "Let me control your ejaculation of your penis!" That day, she teased me relentlessly and I couldn't cum... The next day at work, I couldn't stop feeling horny... After work, I couldn't hold back anymore and I ended up to have sex with my junior colleague...
