My Girlfriend's Little Sister Has Beautiful Legs So Good She Must Be Cheating, And She's Luring Me To Panty Shot Temptation, And I Fell For It, Hook, Line, And Sinker Karen Kaede

Her beautiful legs and panty flashes are a cheat-level temptation from my girlfriend's little sister, and I'm completely defeated! My girlfriend's little sister is super cute, and she seems to have a thing for me, flashing her panties at me on the sly. Is a panty flash a sign for sex?! Is she hitting on me?? "You got excited seeing Karen's panties, didn't you?" "Want me to take your girlfriend's place and have sex?" "She's asleep now, it's our chance." My girlfriend's little sister's beautiful legs and panty flashes drive me crazy—5 rounds of foul-play temptation!! I can't take it.
