He Is Just A Sperm Donor

Don't Look! Here's the rough script: You are a lesbian in a relationship with a woman. The video is from my POV and I am your female girlfriend. All of this information comes out through dialogue you say to me. We have decided we want to conceive and you are going to carry the pregnancy. But we are against anything unnatural (you can talk to me about this throughout the beginning of the video) so we have used a service where a man will come and inseminate you the natural way. I am nervous because you are bi and I'm worried you'll get aroused. The man is here to do it and I am beside you watching. He starts fucking you and you promise me it will just be clinical and not sexual. But as it continues, you can't help that you are getting aroused. The key is to pretend like you are trying to hide that it feels good so I don't get jealous, but you can't hide it. Stifle some moans with fake coughs. You say nothing wrong it's just uncomfy. Try to act professional/clinical and use words like "penis" instead of "cock" and try to pretend you aren't getting horny. As you experience more and more pleasure and squirm you can't hide it you suggest I leave, making up some excuse for why I should leave. Finally you realize you can't help it and are going to orgasm and you confess what's happening and you apologize and say "don't look" "please don't look" "i don't want you to see me cum from this" and then you cum, the man comes inside you, and you are so embarrassed and humiliated and apologizing to me
