However she had planned a special present for me. She tied me to the bed, tight, my penis was already bulging, i knew i was in for something special. ... asked her "what's going on Sarah" which she quickly replied i must call her "princess" and i was now her "slave". My penis was rock hard, rubbing against the rough denim of my jeans, all i wanted to do was release it, but i couldn't, i was tied and she had all the power, i was loving it. She pulled down my jeans, leaving me exposed on the bed,. She was confronted by the sight of a large naked man silhouetted against the rear window. He was standing with his back her her, rocking his hips back and forth. She had forgotten all about being discreet as she gawped at the window, using both hands to shield the light for a better view. Bent over in front of him on a bed was the the large round arse and hips of a woman with her head low down. He thrust forward and she connected this glorious doggy style fucking with the sounds she'd. She wasted no time in getting into the doggy position and lowered her wet mouth right down my hard dick. Billy slaps mom’s ass hard letting her know that she was his bitch for the day and will be treating her like one. He waste no time either and just starts fucking mom like some little poodle and he some great dane. Grabbing her waist he just pounds away telling her what a slut she is and if only dad could she her now getting fuck hard by her son. I get up onto my knees and grab mom’s head. I take your cock out of my mouth and slowly lick down to your balls. I take one of them into my mouth and swirl my tongue all around it. Then I make love to both of them with my tongue. I lick and suck on them while I stroke your thick shaft and make you moan in pleasure. I work my way back up to your throbbing cock and take it down my throat once more. This time I deep throat you and start to lick your balls with your cock in the back of my throat. You scream that you're going to cum and I.
