[Chinese]PPPE-246 Her older sister has big tits and is okay with in-the-vagina sex, and she's seducing me. Yukishiro Ichou

My girlfriend absolutely won't let me do it live….
Will she let me do it live to celebrate my recovery from a fracture? I had faint hopes, but of course, it was a no-go!
Cursing the 0.0 millimeter wall, I fantasized about the pleasure of doing it live and swelled with desire, when her older sister flashed her huge breasts and tempted me with internal ejaculation OK!
I love my girlfriend... but how can I resist such a tempting older sister?
Lost in her beautiful huge breasts and doing it live, before I knew it, I was internally ejaculating continuously!
Eventually, I was caught by my girlfriend, but it felt so good that I couldn't stop thrusting!
