Not very.......

All that Hiro's decision to speed up his bouncing did, was to get your cock rubbing up against his prostate harder and faster, that, combined with your **** of his nipple and cock would only ever lead to one outcome.

"OH FUCK!" Cried Hiro as another, weaker, blast of cum fired out of his cock, the hot cream coating your abs. You smiled as you kept bouncing him, his eyes crossing as you were hitting deeper inside him than anyone had ever done before. Eventually, he caught his breath and whimpered as he asked you how you were still going without cumming.

"I trained myself as soon as I turned 18 to try to not cum quickly when I masturbated because I wanted it to last a long time. What I also found was that wearing a condom helps delay my ejaculation just that little bit longer as well."

Not wanting to fry Hiro's brains too badly, you decided that it was time to finish this up. Telling Hiro to hold on tight, you lift his legs onto your muscular arms and stand up, with Hiro holding on for dear life. You smile and then kiss him as you start to hammer your cock into his grasping hole wanting to fill the condom. You walk towards the shower wall and put Hiro's back up against it for additional support.

After drawing out one last, admittedly weak, orgasm from Hiro, you hold your cock deep within him and fill your rubber sheath almost to bursting point, carefully you put Hiro's legs down, one at a time as you withdraw, making sure the condom doesn't fall off. Once Hiro had caught his breath, he asked that you tie off the condom and give it to him as a reminder of you, the man who had excited him like no other. After you agreed to his wishes, he told you that he would be more than happy to sign a contract for a partnership, after you'd both dried and signed the paperwork, he asked if in the near future you wouldn't mind coming over to Japan to meet his staff.
