His little sister already wants to fuck every day
Recently, three times a week was enough, that was enough and there was no problem. However, it seems that time passes and the desire begins to increase. There is no study that can confirm that, nor any that can refute it. The truth is that this guy is now clear that his little sister now wants to fuck every day and that is a job that he has to do. Take out his cock so she can give him a blowjob and once it’s hard, nail it in her pussy and make her enjoy it. It is your duty and you cannot evade it.
