3s and my best friend is getting horny

My horny girlfriend and I are constantly having silly things on our minds and have set up a goo pool for fun. So that the evening isn't quite so boring, she gets a hot surprise fuck. It makes me totally horny to watch the two of them fucking and to join in properly. Just like me, she's a total sucker for it when the cock sinks naked into her cunt. A lot of cum came out of the horny pig during the load. I was definitely in for a surprise.
