Being taught a lesson .......... I think!

How did I end up on my back in my own bed, legs straight up with my ankles over her shoulders, ready to have my ass fucked from a lost bet? A bet that Alma clearly cheated at as we discover.
I was off to Thailand for a 16 week course in Thai massage at a school recommended highly by a friend I happen to know. My last night in the States, I asked Alma out to dinner. She showed up in a shimmering light blue mini dress that shimmered every time her sexy natural tits moved. Which was every time she moved! We had a quick dinner as she seemed in a rush and as we left the restaurant, I found out why. She had rented a special room that had a pretty killer 3 person hot tub, a shower big enough for 3 and a huge bed with a mirrored ceiling and what I knew to be cameras recording my every move
and mics to catch every whisper by either of us. When we got back to her place, Sue, a mutual friend was also there, waiting for us and to see me off to Hawaii the next evening. After a few drinks Alma & Sue disappeared into the bathroom & popped out a few seconds later looking "different" somehow but too many shots of tequila & a few bong hits had caught up to me. Then Alma suggested we play strip poker and I was eager to see if their pussies were really hairless or was that jus a fantasy I've had. I ended up losing like 6 hands to their one and was soon standing buck naked before the both of them.
Sue, who I've always had the hots for suggested that Alma & her both give me me a massage which shocked me when Alma agreed so fast. Then Alma took off her clothes and I inspected her from head to toe, knowing pretty much what to expect. Classic beautiful Filipino face, brown skinned, sexy fits , a tanned tummy and what looks like a pretty big cock! But that can't be as Alma is a female. Natural born. As my mind struggles to sort out what I've seen or what I thought I saw, Sue slides up behind me, arms lovingly around me, hugging me, squeezing my hips and ass and she starts licking my ear, whispering that we were both gonna let Alma have her way withus as the bet I had lost, stipulated. My body shook violently in both fear and delight.
