My senior's girlfriend's erotic gaze is locked on my erection! I was forced to listen to my senior's bragging about his girlfriend, and while they were flirting in front of me, she got drunk and fell asleep! However, her erotic switch was turned on. My girlfriend, whose big breasts are so tempting, is really in the mood to do it! And she's targeting me, a virgin!! It's not good...! But I want to do it! I'm sorry, senpai! I'm going to do it!!
