I Got my Lesbian Sister-in-law Pregnant

A quick review of background: Lesbian, married Claire is my sister. She and her wife Haley really want a child with their genes. Since Claire can't get pregnant, Haley will be the back-up mother. So that the baby's genes are similar (the same?), they want me to be the sperm provider through natural conception. (I don't know much about genetics) to Claire's.

Haley ovulated three days a week, so they wanted to try to get pregnant every day during that time.

It was like something from The Handmaid's Tale on the first night, when the try was so simple it looked like surgery and I didn't bust.

The second night was great. I got really excited when Claire got involved to help Haley get turned on.

There was some awkwardness after the sex, though. The way Claire's tongue sloppily touched my dick and how it felt were burned into my brain, even though it was supposed to be subtle and "accidental." Then Claire grabbed my shaft to help Haley put it in. It was meant to be helpful and not sexual, but a naked girl touching your rock hard dick is always sexual, no matter what the situation is. Last but not least, Claire spitting on my dick to make it more slippery. Since there was no direct mouth-to-dick touch, I guess that's better? It made sense to come to the conclusion that Claire did not do anything sexually inappropriate with me, so I do not need to feel uncomfortable about it.
