You are at a family reunion and spot someone you haven't seen for a very long time, your step-cousin! She lets you in on a secret. She works as an "accountant" and teases you by showing you her tits outside. Being bored, you suggest that you guys hang in your room! She does and she finds your massager. You let her know some people use it for "fun" and you make a bet that she cannot cum with it. She takes on the bet and loses, which ends up with her being naked and having sex with you! *pov sex without dildo and with implied cumming
