You're having trouble getting hard at the sperm bank & I don't normally do this but I can try to help you out as you & your wife seem like such a nice couple. The magazines in the sperm bank just aren't cutting it for you. so I ask what you really like & you finally tell me that you have a butthole fetish & like unexpected surprises. I think I can make that work so go away to prepare myself for you. I return & tell you that you I'm I can make you cum, but you have to be quick because I need to get back to work. I start stripping for you & teasing my body. twerk, and then spread my ass.I notice it's working so I keep teasing, dirty talking, spreading & rimming my ass with my finger. I ask you if you want a surprise; which of corse you do so I pee a huge stream for you! I then tell you time is running short & I need to get back to work soon so you need to cum soon. You have until the end of a countdown to finish. On each countdown I wink my butthole for you from 10 to 0. Then at the count of 0 I push out a banana that had been hidden in my asshole the whole time! I tell you to cum on my asshole as I keep winking for you! I breathe a sigh of relief that it worked and start fixing myself up to get back to work.
