Definitely

Without another thought, Samus threw herself back into the rubber cock, doing her best to get it past her gag reflex (which was becoming more difficult by the second) the dildo began to swell and harden in her mouth again. At this point Samus could feel the dick being forced down her through, as it widened enough to stretch her lips wide. Unable to even move her tongue around the 18 inch long, arm sized dildo, Samus was finally satisfied. She began to pull herself off the cock, but her jaw could not open wide enough to get more than the thinest first 3 inches out. As Samus became worried, she felt the cock grow another inch down her throat, widening ever so slightly.
