Me (F21) and my FWB (M36) were enjoying a real hot day at the lake. After swimming, we went to one of the public shower rooms to get the sand off of us and our swimsuits. After we were all cleaned up with the water still running we started making out. He was standing to my side and rubbing my clit with his left hand and my asshole with his right. I was stroking is cock slowly letting him rise up. "How about I cum on your face when I'm done." He said into my ear. I giggled and said okay. I bent over for him to enter me, he the tip of his cock on my clit for a little bit and went in easily with me being so wet. He went in and out of me slowly at first, then grab my hair and grind against me. He took his other hand and put the tip of his thumb in my ass for a little bit, I moaned a little bit differently with the new sensation. I could feel his cock get harder as he started banging into me harder. He gasped, pulled out and spun me around. I got down on my knees as he had his cock over me and pulling my hair back. He gave himself a few more strokes and the first string of cum shit over my face on to my forehead and hair. I closed my eyes and felt two more shots go across my forehead down to my nose. I could feel the tip of his cock touch the middle of my nose and warm cum flowed out and went down the right side of my face. I wiped my right eye to look up at him, he was smiling stroking my hair. I stood up and looked in the mirror and laughed. He helped my get some of his cum out of my hair after I washed my face. We put our clothes on and opened the door out of the shower room. Another couple was waiting for an open shower and if they only knew what happened. Maybe they will do something similar. I tried not to make eye contact with them as I still had a grin on my face. On the drive home, he stuffed a remote control vibrator down my shorts and had me try to control myself with the windows down in traffic with all the people leaving our summer town for the week.
