Bodily satisfaction of a huge cock

A man has intercourse with a silicone doll sucking his huge dick. The feeling of her moist lips enveloping his shaft is too much for him and she only takes it in her mouth halfway at first, slowly pulling back, and then slowly taking more and more of him into her mouth until she has him deep in her throat and she holds him there for a few seconds before pulling back slightly and then swallowing him again.
