He's got to try

Matt grit his teeth and flexed his legs, drawing blood away from his member, which is barely enough to hold-off his orgasm. The woman continued to get into it, moaning with great frequency, huskily moaning aloud.
Matt bucked, involuntarily, and the woman suddenly came, her voice breaking to a high orgasmic peak. Matt felt her pussy pull at his penis. He couldn't hold back his own orgasm, and began to thrust widely into the woman as she rode out her orgasm as well. Matt's semen splashed against walls of the the woman's spasming pussy.
Coming down from their mutual orgasms, Matt felt the snake's form dissipate and no longer be bound by it.
