[FNS-071] My girlfriend's sister is so sexy that she missed the last train and came to stay with me in a nasty state. Goddess Jun (Censored)

My girlfriend's sister, whom I've only met once, suddenly calls me and says, "I missed the last train, can I stay over?" She touches me all the time while I'm in a wet state. I can't refuse her and we go into a small one-room apartment, but there's no way nothing will happen if we sleep in the same bed...! "It's cold and there's a gap, so can I snuggle up?" This is a sign of seduction, right?! I have sex with my girlfriend's sister in the same bed until the morning, over and over again until the morning! I can't stop having sex! This is a video of the devilish goddess Jun exploding.
