这个男孩没有女朋友，家里没有人，所以在下午洗澡时，他弯下腰摇晃阴茎。

It was early morning and there was no one at home. The boy lives alone at home and wanted to take a bath in the afternoon and he takes off his clothes and since he has a girlfriend, he shakes his penis with great pleasure. After applying soap, he shakes it vigorously with his hand and semen comes out from his penis.
