Andrew would never turn down a blowjob from anyone he had always thought. But few people had ever compared to his sisters' oral skill. He moaned heavily as she worked more of his length into her mouth, her hand moving to play with his balls. He had always found that sensation pleasant and always encouraged a little ball play whenever he was getting his cock sucked. Not that he needed to tell her that anymore - she had quickly picked up on his desire for such things.<br/><br/>But now her efforts were in earnest, her head bobbing back and forth along his length until he felt the back of her throat. He moaned again and placed his hands on the back of her head though rested it there for now. His cock was soon coated in her saliva which even started to drip down onto his balls. Only lubing him up for better things to cum, he used to say. Not that she needed any help in the lubrication department - her pussy was always wet with the need for him.<br/><br/>"Oh, thats it baby." He moans encouragement down to her. "Suck my fucking cock."
