Your gf asked if she could watch you make yourself cum, but you said no... so she came up with an idea. At your pool party, her best friend approaches you and says she bets she could make you do it. Your gf walks in and you realize it was her plan. Her BFF teases your nipples while talking to you, encouraging you to jerk off for them. She even tells your gf to touch herself beside you. While you look into her best friend's eyes, you make yourself cum for them. (Originally a custom. No nudity, POV teasing, voiceover for "girlfriend's" voice, jerk off encouragement, cum encouragement, sensual dirty talk)
