Ore no Imouto wa Seijun Bitch ~Oya ni wa Himitsu no Hamehame Seikatsu~

Synopsis

"Not again today..."

The squeals of my younger sister, Ena, echo from the next room. Both our parents are at work, and Ena takes advantage of the situation by constantly bringing her boyfriend over and having sex with him in broad daylight.

Hearing this every day is enough to make my frustration reach its peak! Today, I couldn't take it anymore, so I barged into her room.

Her boyfriend hastily retreated, perhaps not realizing that her family was at home. Ena sent her boyfriend off without even trying to hide her naked body.

"Oh no, I haven't come yet... That's right♪"

Ena grinned. "Since you interrupted, I'll have you fill in for me." "Huh?!" And before I could even process what she'd just said, I was pushed down...

"Wow, this is amazing. I've never seen anything like this♪ Oh, I don't have a condom... Hmm, well, I guess it'll be fine as long as you don't cum inside me. Also, I was curious about raw sex♪ So, I'll use this, Big Bro♪"
