I opened the front door and picked up the shopping took a few steps in the hall and I thought I could hear noises. I headed to the kitchen and started putting the shopping away and I heard it again. The living room door was slightly open noticing why wife’s red lacey panties on the floor, my wife sat in the armchair with her legs wide open over each arm with dirty Dave kneeled in front of her. Dirty Dave is an older guy who lives opposite us. Dave was fingering her sweet shaved pussy sliding two fingers deep inside her. I was going to go in but I thought I’d just watch without her knowing. She was moaning and screaming with pleasurer as he fingered her deeper and sliding his fingers in and out faster and faster. Dave told her to play with her tits which she did right away he started playing with her clit rubbing it making her moan even louder and scream with pleasure. He put his head in between her legs and licked her wet pussy and sucking it she told Dave to lick her in a certain place which got her going moaning and breathing heavier and heavier as he made her cum and she called him a dirty old man. She told him to stand up she started rubbing his cock through his jeans she undone his belt then his button pulled down his zip he dropped his jeans to his ankles. She pulled down his pants to reveal his big hard cock she started playing with his balls then started licking and sucking them while slowly wanking him off. She took his monster cock in her mouth sucking him as deep as she could he called her a dirty little whore which I liked the sound of. He told her to stand up she stood up and put her arms around Dave passionately kissing him. He picked her up and opened her legs then he slid that big cock of his deep inside her wet pussy fucking her deep and hard moaning and groaning with pleasure. She then said that’s it Dave you dirty old man fuck me, he put her on the floor she wrapped her legs around as he still carried on fucking then after a while she got on top of him and rode his big cock. He then put her hands on the wall pulled her ass out spread her legs and pussy and again fucked her fucking her good deep and hard. Then he cum deep inside her and he went home and my wife put back on her wet lacey panties and then it was my turn.
