You’ve got one hour to make him cum. If he can keep from cuming, you lose, and I leave you both like that all night, with you sucking him until morning no matter how many times he cums. If he does cum within an hour, you win. Then I’ll switch the two of you around - and you spend the night in the chair, and he spends the night eating you. Now begin, and I’ll sit here and have a drink and watch.
