3 Hole Slut Continued

So besides my hot gf and me learning about pu$$y eating and arse rimming, she also was learning about sucking my cock. From the beginning she was a swallower. Never wanted to waste my cream.
we had just had sex of one sort or another and I told her I would like to have a threesome with another girl present so I could have one on my lap getting fucked and the other girl would be face sitting me so I could please her with my tongue. I was proud to think I could satisfy two girls at once.
My gf surprised me when she said she could take on three men at once; one in her pu$$y, one up her bum and one in her mouth. It never occurred to me that she would even think about being such a three hole slut and it gave me instant wood.
There came a time soon after, this was in the mid seventies, and we were at a swinging party where I had a couple of hot older miles during the course of the evening and had a chance to watch my cute gf getting what she wanted, which was a cock in each hole.
After maybe 45 minutes or an hour she had taken all three loads in her mouth, pu$$y and arse and there was a group of horny older men who would love to keep her holes filled but she took just a couple more and called it a night.
I remember she was quite sore after the party but back in great style after just a couple of days.
