Nikki heard a knock on the door to their room, and feeling naughty opened it slightly. She stuck her head in the gap to see it was Brie's husband, Dan...el Bryan. "Oh hey, Nikki, is Brie around?" Daniel asked, being one of the few people who can tell the twins apart by their faces. When Brie heard her husband talked she panicked, trying to get her face out of her sister's ass.As soon as she felt Brie start to move Nikki shot her hand backwards keeping Brie's head and place. She started to rub her. I had my hands behind my head and I could feel his legs when he shifted over to one side and I thought I felt something hard brush up against me. I'd never touch a man before but I had thought about it and although my first instinct was to flinch away I stayed where I was and let him shift.I sat there thinking, "That is a penis". I wondered if I should move but my girlfriend was still gently stroking me through my shorts and he hadn't moved so I decided to stay where I was. He was not fully. She cupped his ass cheeks with both hands, pulling his pelvis against her face as she fellated him in front of their 19 year old mistress.“What the fuck is going on?” the voice behind Mark said.Jill looked around Mark’s hip to the twenty something guy in the street. He had his arm around his girlfriend, a blond of similar age. Apparently, they’d been walking by and seen the sex show going on in their neighborhood. Amy answered for them.“Hey, Steve! Julia! It’s National Nude Day. And these are. ”I took it out and asked, “You mean you don’t?”“Sure I do,” she said. “I’m just saying, if I enjoy it, why shouldn’t you?”“Why not,” I said. With his cock back in my mouth, I ran my tongue up and down the shaft, the way I like Tammy to do. That made him even harder. I pulled back until only the head was still inside my lips and ran my tongue across the glans. I bobbed down again, taking him as far in as I could, which at that point meant leaving an inch and a half of his cock outside my mouth..
