My girlfriend's 19-year-old son is a loverboy!

Haven't seen my girlfriend for a long time and her son 19 years old is now already big, a real little womanizer. Asked him what the women do, he said that there are many. When he brought me home by car I asked him if he would like to have a mature woman, of course he said, then asked him in we went into the bedroom and fucked nicely with each other. But it remains a secret. hehehe
