Twist of love life

"can I join you ?" Tirah asked. I opened my half closed eyes and nodded weakly as she joined me in the bed under the sheets. I swear if I had a dick I would be erecting by then. She put her arms around my waist as our bodies came in to close contact. My heart pounded vigorously against my chest. It felt so good. I turned around and sat up looking straight into her eyes. I leaned forward for a kiss and put my tongue in her mouth.This went on and on when suddenly the door creaked open and Nelly walked in. "Fuck!" what did I just do!. "I can explain-"she walked out before I could finish. I loved both of them so much and now I was afraid I'd lose both of them.
