DVAJ-370 A day-long non-stop sex life with her who can't pull out due to vaginal spasm Nananami Kawakami

Things were going well as I had sex with my female friend who has a boyfriend, but her vaginal opening was squeezing my penis so tightly that it wouldn't come out... could this be vaginal spasms?! With no other choice, we decided to spend the day together while still joined, but even the slightest movement would cause our genitals to rub against each other and feel good. As a result, we ended up having sex all day! In the bath, in the toilet, even while sleeping with it inserted, just a little movement would feel good and we'd start having sex again... Her vagina squeezing so tightly felt too good! Since I can't pull out, ejaculating inside is inevitable! Maybe we should just live like this, doing only lewd things.
