Mary climbed off the sofa revealing my sister's drenched soaked face. Both Mary and Billy looked at each. "Time to take this to the bedroom. Separately this time boys in one girls in other?" The idea Mary proposed.
"Sounds like a good plan. Doors stay open of course?" Billy replied with enthusiasm.
"Absolutely." Said Mary. "Love to hear each other moan groan beg and plead". She laughed. Mary grabbed my sister pulling her off the sofa and Billy lifted me off the floor. Pushing us in front. Mary spanked Amy's ass. "March". She said. Billy did the same to me spanking my ass I followed back into the hall.
The rooms were next to each other both head boards sharing the same wall. One a neat and tidy, girls room, the other a bog standard excuse of a boys room. With both receiving another spank from them both. Amy was encouraged to into the girl's room as I was encouraged into the boy's. Glancing back both Mary and Billy high five each other before spanking each other butts before remarking. "Go get them".
The best bedroom was slightly clean. The bed was partially made plenty of trainers kicking about the place. The odd pile of clothes dumped in a corner. On his bed side table was range of dildos each one progressing in size the further they get from the bed. Buttplug to horsecock.
Initially terrified how much is he going to destroy my ass. One beauty of the room was the fact at the end of the bed was a floor to ceiling wall to wall mirrors. My room was similar with a large mirror facing my bed so I could see myself being naughty and I loved it. So this really turned me on.
Billy turned me to face him pushing my ass onto the bed, he knelt down grabbing my ankles lifting them up over my head spreading them forcing me onto my back. My ass opened up on the edge of the bed he leaned in closer spat a big dollop of spit on my butthole. Licking is lips he dived in to my ass furiously licking it in and around my hole. Once again another first for me someone licking my butthole and oh my god I was in love. "Oh yes..." I begged. "Lick my hole make it nice and wet." Not too disappoint he licked and smothered every inch of my hole making it all slobbery.
Getting up he reached for lube on the table. Squirting some on his cock and his fingers he rubbed in it in his cock and onto my hole. Lining himself up the head of his cock pressed against my somewhat virgin ass. He asked me staring into my face. "Are you ready? After this you can no longer say your straight and you'll be a cock hungry anal slut just your sister and mum".
It would be at that precise moment I would hear my sister scream. "Oh come on you bitch fuck me harder". With my heart racing his cock was ready my hole was hungry.
Nodding to him I said. "Fuck me! I want to be a slut like them."
Plunging his cock into my ass. My hole stretched wide with little prep work I could feel the strain it was hot it was tight it maybe of been too much. A break or easing was required but if I got him to stop I might stop all together. Burying his cock deeper and deeper inside me I thought to myself fuck this a lot bigger than I thought. "How much more?" I pleaded and groaned.
"Just about there" he said feeling his hips against my ass I knew he could go no further. Taking in loads of deep breaths. He kept it there for a bit for me to relax which was difficult thinking I needed the biggest shit imaginable. After a minute or two he pulled out gently not completely he added more lube and began inserting back in still pain but not as much. With 5-6 pumps of my ass the pain eased the pleasure arrived and his cock was sliding in and out with little resistance. "Mmm... now this feels nice." I said. Billy smiled spanking my ass. He soon picked up his pace now slapping more of his hips into my ass a good rhythm of slapping noise followed. Holding on to my hips he started fucking me like a slut.
