Is This Really Sex?

IS THIS REALLY SEX? Let me explain this title. As background, I am a married male 60 plus year old and I work in an office on construction sites that are usually far removed from populated areas. We are always deployed for six to nine months at a time at any each job site. I am the construction site office manager. The office staff and the field foremen are permanent company employees and are moved from job site to job site with each new contract. All other construction workers are hired from local union halls and commute daily to the remote job site. However, the permanent employees live in trailers on the job site. As administrative office staff, I have 2 female employees. The oldest Patricia is in her mid 40's and the younger lady Sharon is 20. Sharon has the looks and physique of a Playmate model. Both ladies get along well and are excellent workers in each of their respective work areas. Each of the ladies are provided their own small trailers on site to live in. My living accommodation is one room as part of a larger trailer that also serves as the field site administrative office. The field superintendent's trailer also doubles as his field construction office. We all have worked together as a team at three previous construction sites. Because of the remote areas of these job sites, our social life is extremely limited. Now to the meat of the story, Sometimes the conversation (gossip) between the two ladies gets pretty intimate and explicit. As an example I know each and every time either of them are having their periods menstruating. All types of sexual intimacy , positions, likes and dislikes are openly discussed in the office. They are both well aware of when their conversations have turned me on and have commented on the obvious tent in the front of my pants. Sometimes we will continue to work in the admin office after normal work hours and all the temporary construction workers have gone home for the night. Recently the two ladies have collaborated on ways to help me in relieving me of some of my pent up sexual needs. There is no threesomes or intercourse involved but each of the girls has developed her own way of seducing me with their own unique technique. Sharon will rub her clothed ample breasts against me. She will allow me to massage her twin swells through a sweater or bra. Many times she will even go topless to tease me and has even allowed me to play with and suck on her hard perky protruding nipples. While she will allow me to squeeze her rear, she remains fully clothed and will not allow any other touching or feeling below her clothed waist. Even tough I may have wanted more, she will not allow any other intimate contact more than what I have already described. While Sharon will rub her naked topless body against my clothed hard on, she will not have any mutual nude body contact below my clothed waist. She really is a tease, but I love what ever I can get. Pat on the other hand being older and more sexually experience will allow total nudity at any time. While she also will not allow any actual intercourse, she will allow me free access to her two saggy breast as well as unlimited feeling up of her mature pussy. Pat loves to have me finger fuck her vagina lips while we mutually masturbate each other. Pat will even suck my cock as long as I don't try to have actual intercourse with her. She is extremely experienced at massaging my balls while masturbating my cock and bringing me to organism. Unfortunately at my age the quantity of sperm fluid flowing from my cockhead has reduced over time. Neither girl will perform in front of the other, although at times they will mutually either individual or collectively tease me throughout the day but if we have to work at night one or the other will find a way to seduce me when the other is not around. I know that from comments each as made that both Pat and Sharon are aware what each has been doing for me. The girls have stated that since no actual intercourse is taking place, they are NOT having sex with me but are only relieving each others adult tensions in the privacy of this remote work environment. My wife states that she is satisfied that I am meeting her sexual needs when I am at home. We are both practicing nudist at home, and we have openly masturbated either ourselves or each other whenever we felt like it. We have no children at home and we are not swingers. There has been times when she has masturbated me in front of another women. We have a single female neighbor Joyce who knows we are nudist but regularly walks in our kitchen in the morning unannounced for coffee. To tease our neighbor, my wife will frequently play with my manhood and my balls until she gets me erect, just to see the reaction on Joyce's face. Joyce's looks are amazing. Some times her eyes bulge, her mouth opens and then sometimes she quickly leaves without a word. In any case she will frequent appear the next day unannounced. Joyce has never disrobed or made any advances to play with my floppy or erect naked gentiles. My questions for the SoloTouch readers is: Are the actions of Sharon, Pat and I considered sex, when my wife exposes both our naked selves to Joyce?
