Sexy bets

Right okay ladies I need your help. Me and my fiancé have made a bet. I said I bet he gives into sex on Wednesday before me because I've been on my period for a week now and it will be more than a week we've done anything so we made a bet for who gives in first. His side is that if I give in first I have to suck him off (I have never done this either so I will have to do it now if I give in) and my side is that if he gives in then he has to give it to me like he never has before in a different way to any way he has done and see how long he can last ( he says to do a different position normally but never knows what so he's by himself this one and never lasts long) so my question is how do I make him go mad and make him give in first for it without it showing that I will give in first?
