SNOS-416 | I spent all my time—endlessly, intensely—having sex with my tutor, a cute, mature girl three years my senior, in a house where my parents weren't around. — Airi Nagisa

With my parents away for three days, I’m left all alone with my tutor, Airi-chan… I’d always found her cute and harbored secret, lustful intentions toward her—and with my parents gone, I decided to make my move. To my surprise, she welcomed me with open arms, leading to three whole days of non-stop, live-in sexual encounters! For an unpopular, overlooked nerd like me, spring has finally arrived. I can’t help but see Airi-sensei solely as an object of my desire! "Shall we cross the line?" There’s something about doing the "forbidden" that just fuels the fire. We began a physical relationship while my parents were away; she gently spread her legs to welcome the naive advances of her own student!
