Yume Senpai, Wanting to Improve Her Sex Skills, Makes Me—Known as the AV Expert—Ejaculate Repeatedly in a Creampie Experiment; During Free Time, She Gives Intense Sex Lessons to Understand Men's Pleasure Points, Nishinomiya Yume
Called the AV Doctor, my vast knowledge of sex was exposed by Senior Yume. Worried her new boyfriend might think she's bad in bed, she declared she wanted to train and improve her skills. She asked me to be her test subject, saying, "Tell me if it feels good," while gradually becoming more and more erotic—my cock couldn't keep up.
"You're my experiment, so speak up if it feels good!"
"How many times are you going to make me squirt?!"
"Does it feel better when I lick you noisily!?"
"What the hell, don't cum inside me without asking!!!"
Using my knowledge, Senior Yume rapidly grew more skilled and increasingly slutty, advancing at a pace I couldn't match. Unable to meet her escalating demands, I fell further behind.
This filthy relationship keeps spiraling deeper.
