I'm your girlfriend and I caught you jerking off to a pic of your big sister!-- allegedly. So I offer up to help you finish, by pretending to be your older sis. Stripping down from my house clothes to nothing at all, I tell you how hot this fantasy is. Encouraging you, gently instructing you, and dirty talking the whole way. I lovingly tell you to relax and imagine these tits are your big sis's as I take you to the hottest orgasm. x -- Focus on my perfect natural tits, breast play, "cum on my tits" --Girlfriend roleplay as big sister --naughty roleplay and dirty talk
