You gave Daniela all your precum you could produce. better said, she kept you on the edge and enforced it. (see part A). your muscles are weak. your balls are blue. your body and your bladder absorbed already some of your cum, you loose during two dry orgasms in this edging session. finally she allows you to cum on her lips with the lousy rest of your remaining liquids. this is the time, when you realize that Daniela can handle your dick better than you could do it by yourself. perhaps a matter of discipline?!
