Despite his weak appearance, he has a big dick and is a very good lover, but since he has never had sex before, he is not really aware of how good he really is.He masturbates to pornographic films at home, so his dick is automatically trained. Thanks to this, even though he has never had actual sex before, he already has a dick that is hard to get off with a normal partner.[From official site]
