Is it normal i saw my friend voiding in the pool

It all began last Sunday, my friend Palmer invited us round to his place, he has a pool and a high spec BBQ. While we were inside chatting and waiting for everyone to arrive I said I needed to go up stairs to the bathroom, I said I'd be a while because I had to open my bowls and then take a shower because we were going in the pool, for some reason everyone just looked at me like I was weird.

Anyway, I didn't really need the bathroom I was just buying some time so I could go into Palmer's Mom's room, she is so hot and I couldn't resist the opportunity to lay some of her lingerie on the bed and "relieve a little tension".

Because of the design of the house and the position of the pool, Palmer's Mom's bedroom window is the only place were you can see the pool from the house. That's how I saw him, filling the pool with his golden waste like some sort of animal.

I went back down stairs and was going to tell everyone but then I realized, how could I, he'd know I saw him from his Mom's room, and he'd realize were his Mom's panties had been going. I couldn't say anything and the worst part was...I had to get in the pool, It would have looked to suspicious if I didn't. I definitely needed a shower after that.
