Fake Date Turns to Cheating

Looking to do a role-play where we are bf and gf, only thing is, I agree, against my better judgment, to let you go on a fake date with a guy. Like your sister begged you to go to a wedding as a +1 for her male friend whose gf just dumped him. Whatever. The point is it is a fake date purely to satisfy their social obligation. Only thing is, how fake can a date be? Pretending to be together means some level of touching, kissing, etc. And explaining things since I might know people who are there. So my idea is that this fake date turns sexual as he turns you on and you come to learn he has a massive cock. Manipulative and gaslighting.

Must be willing to share pictures and verify. Ideally looking for white, cute, 20s or 30s.

I want this to be texting based. You and I are in contact the entire time over text, from you getting ready through and me being apprehensive to you eventually cheating on me. Looking to do this over telegram or text. Roughly $50 give or take. Paid however, cash app or venmo or paypal or whatever.
