    omg, nummer 1, das een grapje zeker? is het een etalgepop? nummer 3 heeft wel een beetje mislukte borsten, maar dat koppie op foto 3, damn, dat is wel heerlijk. 2 ben ik al vergeten, dus 3 pakt mijn stem vandaag! Nummer 1 is nog best te doen als je alle plamuur eraf bikt. Lekker lijf. Nummer twee schuif ik heel snel door naar een blinde want die is lelijk en heeft volgens mij een baard op haar reet zitten. Kies uiteindelijk voor nummer 3. Jammer van de faketetten, maar is voor de rest echt een lekker mokkel. Beter fake dan niks
