This series has reached its fourth installment, and it's the turn of the voluptuous, large-breasted Ai Sayama... oh wait, I mean "Ai Sayama"!
The plot is similar to the previous installments. The male protagonist and his girlfriend live happily together in a rather large house. One day, the girlfriend's older sister, Ai Sayama, comes to stay temporarily. The two sisters engage in some intimate activities, sharing clothes. Ai Sayama even borrows some of her sister's clothes. When the protagonist returns home, he sees a familiar voice looking for something in the closet. Her alluring, shapely buttocks instantly ignite his lust, and he rushes over, rips off her underwear, and thrusts into her from behind…
*Slap slap slap slap slap slap slap!!*
Ai Sayama, startled and aroused by the sudden penetration, begins to moan and enjoy it. Just then, she hears her girlfriend's voice outside. The protagonist realizes it's not his girlfriend, quickly pulls out, and pulls his pants back up. Luckily, he's not discovered…
Because of the guest, the protagonist can't fully enjoy sex with his girlfriend, and the inexplicable half-penetration only fuels his lust. The next day, thinking the sister has left, he returns home and sees the familiar voice again, naked, having just showered and wrapped in a towel. He can't resist again and thrusts into her!! But…

My sister hasn't left yet!!
It's my sister again… But this time, the male protagonist couldn't hold back either, and with a quick thrust, he ejaculated inside Ai Sayama. Then, in a saintly mode, he shamefully hid in his room. However, these repeated sexual urges finally got Ai Sayama aroused!

Yes, aroused, Ai Sayama retaliates, entering the male protagonist's room, pulling down his underwear, and shamelessly enjoying herself. After being ambushed before, this time it's her turn!!
The male protagonist has clearly messed with the wrong person; Ai Sayama is even bolder than him, wanting it constantly, draining him dry with each thrust. Compared to his girlfriend, the older sister has bigger breasts and is more daring, so he passively accepts and ejaculates inside her without hesitation…
From the initial ambush and thrusting to the actress later taking the initiative, Julia's performance in the previous film already made me ejaculate wildly. I'm looking forward to seeing how perverted the more experienced Ai Sayama will be, but I hope she can lose some weight XD!
