Normally I would never let go of my dick during a session. But now I let go of it exposing it to her in all its glory. At this point, I decided to be ... full exhibitionist.I moved my hand to the top side and I pushed my dick so it extended completely out from my body. Doing this always made it look longer. It’s an unnatural position but I know what it looks like after examining me in the mirror so many times. I was showing off for my mom. From what I could tell, she enjoyed every minute of it.. Then she hugged me & I put my lips on her lips & almost 5-6 minutes we kissed each other’s lips. After this long kiss she become so hot & her boob’s r moving with the rhythm of her breath. i was holding her with my one hand & with other hand I was caressing her hairs & cheeks. again our lips were locked & we rolled on bed & this time I was on top of her & kissing her passionately. Her one hand is pressing my back & other is pressing my face on her face. I start sucking her lower lips & she. “Chris has arrived now, so we’re on our way you fucking slut. Get that dirty cunt nice and ready for us”.I asked about the family while we were driving over and we discussed what we were each getting mum for her Christmas present. Although what I, and particularly dad, was doing was so wrong it had strangely brought us closer together and had bred a certain familiarity and we felt more comfortable together physically.We parked up a couple of streets away again so that the car wasn’t seen. I came back in and set the bag down on the table right in front of her and unzipped it, bringing out the lengths of rope I was going to use to tie her to the table. I heard Maggie softly moan as the ropes came out. I had never tied her up before and didn’t know how she would take to it, but I didn’t have to worry–seeing these ropes made her instantly wetter and hornier! My Maggie was a kinky little slut!I knelt down, tying one ankle to each table leg and then I moved around and tied her wrists.
