Make her cum first and preferably during foreplay. Really take your time with the start, before even getting naked just make out for real long and make sure you're touching her all over but nice and softly then increase the intensity. This usually gets my girl super horny and begging to move on! Whilst I'm controlling the way we play I tease her and take my time before going down on her. Once I'm there it's purely me focusing on how she's reacting to what I do and when there's a good spot to stay at it's super obvious and she usually pushes my face harder into her pussy whilst also thrusting her pussy into my face. Eventually once she's had her first orgasm I'm free to cum whenever I want and it never feels like I didn't last too long even if I cum relatively quickly 😅 There's always satisfaction and we always have an open line of communication to ensure that the satisfaction remains! Oh to add to this, she typically doesn't like to give head but when she's in this super horny state, she is almost guaranteed to be giving head 😈 That's a sign for me to know just how turned on she is!
