The next few days were different with Sira living with us. Elena and I had made love often but, with Sira, it was constant. I also realized that she w...as not limited to just making love, or in her case, having sex with just us. The second time she turned up missing for a while, Elena caught her at the home of another couple which Elena didn’t like. Elena ended the experiment which suited me. It wasn’t good for us to share in that manner.We continued with our life as a couple while I helped watch. I have a thing for panties and before I fucked her I wanted some panty fun with Ella. I pulled her panties down her tanned legs and put them up to my nose. I smelt her pussy juice, so sweet and aromatic."So you like my dirty panties? Shall I blow you as you taste them?"With that her mouth was back round my cock. Should I tell Ella I want her to pee into her panties or wait? It may put her off. I didn't say it, but knew I had to at some point.I felt her push my cock into the back of her throat.. During the whole 45 minutes it took to get there she never took my cock out of her mouth. I had a terrible time trying to drive on the icy roads and keep from cumming at the same time and still finger her hot dripping pussy. When we finally got to where we wanted to be I stopped. Kay let go of my cock but only so she could crawl over the seat to get in the back. I quickly followed her. She way leaning back and I just naturally started licking her hot pussy that was already over flowing with. When I was almost there I dropped to all fours. The plan was to crawl around the back of the couch and under the hide-a-bed giving me an optimal view of the tv and keeping me out of Daddy's view. I held my breath and slowly made my way without a hitch. I smiled looking up and the mattress wire bending down in a mound where my dad sat.Shimmying up on my stomach, careful not to make any noise I made my way down to the foot of the bed to see the screen and got comfortable, my arms crossed under.
