show her your ready for her to fuck other guys, invite a friend over and let him seduce her in front of you.
If that's what she wants they will fuck, most likely that night, remember this guy must be smooth, handsome, well dressed, confident and hung like a horse. Make sure she is horny and tipsy before he gets there. Casually mention most of women where he works have had an affair with him and roomer has it his dick is huge. get someone to call you, grab your car keys and run out of the saying there is an emergency at work and you will be back in an hour. most likely they will fuck if you set it up right. lol
