I'm your wife's best friend. We've fooled around before behind her back. Like the last time where I tried on my panties for you and gave you a blowjob (she won't know panty try on). You've come back as I'm about to get changed. I take off my clothes for you and lay back so that you can take me in missionary. I then get on top in cowgirl (no penetration shown) until we both cum. I talk about much better I am than her and how maybe someday, we can play around without the risk of getting caught.
