Claire envelops your entire cock with her tits and pronounces only a single word that makes you shudder: Override. Then immediately starts the rush, Claire keeps her tits tight around your cock and use them to stroke whole your cock. It’s unbelievable how she can move those massive boobs so quickly. You try to speak but these override in row break your breath.
YOU: …
CLAIRE: ahahah…sorry but i can’t hear you. So, cum and game over, i’m so good to let you have a good orgasm if you cum now.
YOU: N…O!
CLAIRE: How many other overrides can you last?
YOU: How many overrides can you perform?
CLAIRE: WOW... From prayer to provocation! Let me think…last week to persuade a guard to give me a security code i've performed about 30 overrides consecutively.
