Shy Incubus Sigma

Sigma is a reserved individual who isn't good at his job as an Incubus. You came along, just what he needed to succeed, but he's too reluctant to ever accept your advances, despite both of you willing. He can't seem to get it right, but today you'll help him lose his virginity. He's a flexible guy who can satiate all your needs, but he's too nervous to do it. What do you do to get him around your finger? To take a chance?
