About 17 years ago, I was a bull for my former college roommate and his wife.

He was 24, she was 19, I was 22. He was diagnosed shortly after they were married with a unique genetic disorder, I can’t recall the name, that would likely be passed to any future children.

I was finishing up my degree and under a lot of stress, so I was surprised when I got a call around Halloween to come visit them and hang out. We had a great time, and later that evening, they laid out the problem and proposed that I be their sperm donor, as aside from height, he and I were very similar in features. It took me a while to agree, but I’m glad I did. They had legal paperwork drawn up by an experienced attorney, and I had no rights or responsibilities to any potential children.

I ended up spending Thanksgiving weekend with them, making love to her and filling her up multiple times. We made it a thing, frequently until the end of the semester, with them coming to stay with me some weekends for fun, and her spending a few nights around finals helping me relieve stress.

I got a call in February that we had been successful, and in late August, she gave birth to twins (as almost every first pregnancy seems to happen in her family). They were overjoyed, and I was happy to have been able to help them.
