Andrew watched, mesmerized, as his sister took him deeper and deeper into her mouth. Her hand massaged his balls and their size difference was very clear and apparent now. She was tiny, but - fuck - she was tiny! Everything about her was tiny! The thought of his cock splitting her in half filled his mind as she took him into her throat.<br/><br/>Any other girl he had had been with recently and he'd have his phone camera ready or already snapping pictures. But this was different, this was his sister and the wrongness of this made it so fucking arousing!<br/><br/>"Fuck yeah...swallow that cock you little slut..." He moans again, watching her take him deeper into her throat.
