Girlfriend’s Busty Sister Missed Last Train and Stayed Over

Synopsis

Late Saturday night, an unexpected call comes in. “I missed the last train, can I stay over?” It’s Yuu, your girlfriend’s younger sister. I thought I’d refused, but minutes later the doorbell rings. She lets herself in without permission. She’s been drinking and is acting unusually touchy and close. Her top is loose too… She’s pressing her chest against me like she’s deliberately tempting me. What if my girlfriend finds out…? “Hey, you’re touching me.” “Huh? I’m doing it on purpose.” Oh no, I might be in trouble.
