Cousin came in to my room during birthday party. Maybe long time dint saw her, feel that her bomb grow up so much. Then I tried to ask her what her boobs size and how come grow so much. She notice that I feel interest on her boob then she ask me to touch and measure it by myself. She seem enjoy when I touch it with my hand. Then I try to pull up her bras and touch her tits, she dint resist and ask me to touch harder. In the mean time, I feel that her pussy are squirting then I take off her panties and licked her pussy. She enjoy the moment that i licked her. At the mean time, she noticed my dick is getting larger and she asked me to pull off my shirt and put my dick into her pussy. I enjoy fuck with her and lick her tits. We where fuck around 40min. At the end, i cum inside her mouth and she help me to clean my dick by licking on it. For now, we have sex every time when my cousin came to my house.
