A typical male-female questionnaire for AV: Years-old male and female classmates challenge each other to a series of sex until cumming inside! 17 DVMM-334

Invite a slightly tipsy man and woman from a class reunion to a hotel! Say that if they ejaculate inside each other, they'll get a 100,000 yuan bonus, and then let them be alone together! They both have their own families... and after many years they're still good friends... but their lust gets out of control!
