Too bad it wasn't me having the sex.

This morning I was awakened by some strange noises. My next door neighbour had left his window open. I won't make this a long drawn out blog of everything that transpired because I don't want to relive it all.
The short end? He squealed like a pig, literally...he sounded like Ned Beatty in "Deliverance" At first I couldn't tell if it was him or her, but then he called out her name. The orgasm lasted for what seemed like eternity to an awakened and tired person.
The weird thing is....I only heard a slight..."mm hmm" from her...that was it? Was he doing it right? If he squealed like a pig and was going to town, I expected at least a bark, whinnie or moo from her.
I'm going to go and take a nap.
