Cum eating istruction till last drop

The goddess Raven has an important task for her slave: to make him taste her own cum! The goddess orders her slave to take a glass and a spoon for this exciting task. The goddess teases him, she knows that with her perfect ass and her fantastic curves the slave will need to cum soon! When the goddess sees that the slave is about to cum she orders him to cum inside the glass, all inside! The slave must wipe the tip of his cock with his fingers and suck it! The goddess orders him to take the spoon and taste his own cum: but he must not swallow it right away, he must hold it in his mouth, on his tongue, and feel his own taste! The goddess is very amused and excited to see the slave humiliating himself like this! The slave must continue until all the cum ends up in the glass... eh no, not a drop must be lost, so the goddess orders to fill the glass with water, stirs and swallows everything!
