Purple Kiss, part 3

I felt the head of a cock pressing up against my asshole but could not look back to see who it was. It didn't take long to figure out that it was Marlena. Pain shot through me as she tried to force the tip of her massive cock into me. I groaned and jerked forward until my head was pressed up against Amanda's stomach. I felt her soft breasts bounce on the top of my head.
“He's so tight,” Marlena marveled.
I heard a small click as Amanda continued to thrust into my mouth. I felt something against my ass and tensed again. “Relax mijo,” Marlena said.
I felt wet fingers slide all over my ass and realized that she was applying a handful of lube. I relaxed a little and Kristin giggled. Marlena massaged my ass for a few moments then slid one of her fingers inside of me. She thrust it back and forth a few times before inserting another, then another. My asshole felt like it would not open any further as she slid her fourth finger inside it.
“Relax,” Marlena whispered.
I relaxed a little more as she began slowly twisting her fingers. Every once in a while she would try to spread them apart, but my muscle was too strong for her to make much progress. The pain had subsided so I started rocking back and forth slightly.
Amanda grabbed her dick and began stroking it quickly. The pressure on my ass increased, but I was too focused on receiving Amanda's load to care. It wasn't until she was finished cumming up into my mouth that I realized during the process Marlena had shoved her entire hand into my ass.
Amanda hopped off of Kristin, and I scooted forward replacing her ass with my mouth. Behind me, Marlena pulled her fist out of my ass, then I once again felt her cock pressing up against my hole. The pain was still there, but it was much more tolerable now as she eased herself inside me. By the time she was all the way in the pain was gone and there was only ecstasy. She started off gentle, but by the time she came she was fucking me as hard as she could and I was loving every second of it.
