Hi again , well , my gf and i were fooling around in these days . when i rub her , i know that she is very pleased wif it . After a few hours later , she has got started to hurt . she said , the entire surface of her organ was hurt . moreover , when she goes to pee , it still hurt . then , after a few days , that hurt is disappeared . I rubbed her without taking off her underwear with my 4fingers , not into her . My hand effort is not too high . just slow and steady . - that is happened becoz of her delicate organ ?' -that is happened becoz she's never been masturbated herself ? ( now she is 18 ) Does anyone know ? Pls kindly answer . I can't stand when she's got hurt ='( . Please.. ?
