I'd just spent the night with my girlfriend's beautiful and sexy sister Miriam, exploring her lingerie collection and her amazing body. We'd been playing dress up for hours. She would change her outfit and pass me some new clothes, a pair of frilly knickers and a baby doll, a bra and matching thong, a skirt, some stockings, fucking each other along the way.
I wasn't sure what time it was but I could hear birds beginning to chirp outside her window, so morning wasn't far off. We were lying on the floor together, our bodies intertwined, lingerie and clothing scattered around the room, mostly covered in our juices.
"You'd better go." She said. "Lisa will be waking up soon and will wonder where you are."
I stripped off and redressed in my own clothes, gave her a sullen look and tiptoed back into Lisa's room, sneaking into her bed quietly. I lay there staring at the ceiling for a few hours, my mind recounting every moment with Miriam.
Sun had filled the room and I heard Lisa mumbling next to me. "What time did you get to bed, baby?"
I tried to reply as calmly as I could. "Oh, not that late. How are you feeling?"
"My head hurts. I can't remember going to sleep," She said as she held her head in her hands.
I offered to make her breakfast and headed off to the kitchen to brew some coffee. Miriam wandered in wearing a silky red dressing gown that clung to her ass and revealed her breasts as she grabbed a cup from the cupboard.
"I need to ask you a favour." She whispered. "I want you to keep what happened a secret and not break up with Lisa. She really likes you and I don't think she'd take it very well right now if you ended it with her."
I was stunned and too tired to process anything. She continued whispering. "It doesn't mean we can't do it again but we have to be careful. Do you think you can do that for me?"
"Of course," I replied. Not quite sure what was even going on.
Lisa stumbled into the kitchen and sat down, her head resting down on her folded arms. Miriam winked at me and went off to attend to her hungover sister while I finished up the coffees. After breakfast, I made some excuses and kissed Lisa's head goodbye. Miriam handed me her phone number on the way out and blew me a kiss as I left when Lisa wasn't looking.
A few days later I went back to Lisa's place, hoping to see Miriam but she wasn't there. We had something to eat, watched a movie and Lisa practically begged me to go to her room with her. She had made an effort to dress nicely, wearing a short skirt, wet look top, heels and stockings, but didn't look anywhere near as good as Miriam.
We sat on the bed and she quickly undid my zipper, pulled out my cock and started sucking my dick. I wasn't really that into it until I noticed a photo frame on the side dresser with a picture of her sister Miriam. She looked so good and my mind raced back to our night together.
I grabbed Lisa's head and started fucking her face, staring at the picture, remembering everything we'd done that night. I was so horny I didn't even notice her gagging, struggling to breathe as I held her head down fucking her mouth until my cum oozed deep down inside her throat.
"Mmm Mir..." I groaned almost saying her sister's name out loud. "Mmm, baby," I said trying to recover.
She lifted her head up, swallowing the remaining cum in her mouth, her eyes watering.
"Was that good baby?" She asked. I nodded trying to give her a sense of false confidence.
"Shit!" I said. "Is that the time? I'm supposed to be covering a shift at work tonight!" She looked disappointed but said she understood as I rushed off out the door.
I couldn't take it anymore, I had to see Miriam again. The thought of dressing up with her was driving me crazy. I texted her phone and asked her if we could meet again. After a few hours, she replied.
'Meet me at your place in one hour. Text me the address.' I texted her back and waited. An hour passed. No sign. Five minutes, ten minutes, twenty... thirty. I just sat there waiting for the door, checking my phone every few seconds. Nothing.
I'd just about given up when I heard a faint knock at the door. Rushing to open it, I almost tripped up on my way to see who it was. As I unlocked the door, I'll never forget the way she looked. Standing in the hallway wearing a long black overcoat, her hair all done up and her gorgeous but subtle makeup, was Miriam.
