After the initial sexual contact between dad and I, our sex life together only got more intense as well as the frequency. Most often if I did not have a friend staying over I slept in my father's bed with him. There was not a day or night that went by that dad and I did not enjoy our new found sexual relationship with each other. I loved sucking dad's cock, licking all around his mushroom head, tasting his precum as he got excited, deep throating his incredible 8 inch cock, and swallowing every last drop of his cum. Dad was only to happy to return the favor licking and sucking the head of my cock as well. He also never spilled a drop of my cum as he swallowed my massive amount that I came every time.
Not only were we enjoying each other orally, but we also enjoyed watching each other masturbate and quite often would finger the other one's ass as he masturbated to finish spraying cum all over each others face.
We watched a lot of porn together. Not just gay porn, but incest porn (father /son, brother/ brother and brother/sister, daddy daughter, mother son, and straight porn as well.
We did a lot of frotting. Usually I was on the bottom as dad liked being on top and I liked being on my back with him on top of me. I loved feeling him rubbing his hard cock on my cock mixing our precum together on each other's cock. We both really enjoyed this position I believe the most, and sometimes were in this position for as much as an hour or more. Dad would really pump away fucking my cock with his, with both of us sweating as our sweat mixed with the other's. Our breathing would become heavy and labored. We open mouth kissed, talked dirty to each other, and I loved telling dad to fuck his son's cock good and hard. Telling him to make me his fuck slut until we both would finally and almost always, simultaneously cum together all over each other.
We also progressed to anal with each other. Since neither of us had much if any experience at this, we progressed slowly but frequently with this, taking turns fucking the other, until we both became comfortable and enjoyed giving and receiving cock up our ass. Neither of us wore any kind of protection and we both loved the feeling of bareback fucking. We found some really great lubes and soon our cock's were sliding in and out of the other one's ass with ease. Whenever I fucked dad, I would always reach around jerking his cock making him cum as I came in his ass. I on the other hand, had started enjoying the feeling so much on my prostate that I was able to experience prostate orgasms as dad pounded my ass with his cock. I loved feeling him flood my ass with his massive amounts of cum. It wasn't long into our new found relationship that we both started discussing sex with other people, ie, threesomes. That was when the discussion oh bringing John, my friend, into our world took place.
Dad knew all about John and I having sex as I had told him. With my dad's permission, I also told John about my dad and I and how it began. John was immediately turned on as I described sex acts with my dad to him. Whenever John and I discussed my dad and my relationship, John would immediately get hard and start rubbing his cock. Within minutes of telling John things dad and I did, John and I were having sex with each other as well. Within a couple of weeks of me telling John about dad and I, he said he wished he could join us. If John only knew that this was my plan all along, and dad fully knew about it. With John also being 18, there were no problems standing in the way other than the secrecy of course of what we were doing. I told dad that John was wanting to get involved and we made plans for the next weekend that John would be spending the weekend with dad and I. Dad's bed is really going to get a workout now and a lot of cum on the sheets. That is any cum the we don't swallow first or have leak out of our asses.
All of us were excited when Friday evening rolled around and John arrived at the house. Dad was great at breaking the ice with John with easy and upbeat conversation at first calming John's nerves. Dad and I were each only wearing gym shorts when John arrived and within 20 minutes John was as well.
