[ADN-618] "Can you make my wife pregnant?" My best friend asked me, so I let him cum inside her until she got pregnant. (Censored)

"There's a problem with my sperm... the chances of pregnancy are extremely low. Can you get my wife pregnant? You're the only one I can ask." When my best friend told me this, I initially agreed, but to be honest, it was too much of a burden and I was thinking of refusing. Of course, this was an opportunity to have a relationship with Goba-san, who I'd admired since my school days, and to be honest, I wanted to do it, but emotionally I thought it would be difficult. As if she understood my feelings, Goba-san looked me in the eye and invited me. "Is it okay if it's me...?" When she said that... my reason was easily shaken.
