SABA-475 We are a lovey-dovey couple, but my beloved girlfriend got fucked by an AV actor right in front of me!

Boyfriend Kenta (in his 20s) and girlfriend Moe (in her teens) have been dating for a year, and seeing his girlfriend, who has little experience with men, get excited by another man's dick makes him hard... This is the lovey-dovey couple's first and last AV appearance!
