I bite down hard on his glans and insert a ball probe to get it in and out quickly, I want to push him to the extreme that he can't take any more and has to beg for it to stop. Le muerdo fuerte el glande y le introduzco una sonda de bolas para meterla y sacarla rápidamente, quiero llevarle al extremo que no soporte más y tenga que suplicar que pare.
