"N-There's no way I'm going to cum in one minute!" ~Toys that make you cum instantly VS JD that never cums

"I'm not cumming...I'm not cumming...I'm not cumming...!"
Every time he rubs her soaking wet underwear with a vibrator, his childhood friend moans, spilling her love juice. I want to make her feel even better.
--My childhood friend Kuori is always in my room.
The air conditioner is being used as much as I want, ice cream is being eaten without my permission, and I'm at the end of my patience...!
I'm losing my patience, so I propose a fight.
"Let's see if you can withstand this toy (*High performance instant orgasm specification) for 1 minute!" Contrary to her strong attitude, her flushed body is on the verge of climax!
The naughty battle between the instant orgasm toy and the JD who will never cum is about to begin!
