It was late February. We still had about two months before start of the racing season. Dad's coverage of World Championship Motocross Racing in the previous season had expanded the desire for Dad's pictures and race reports from several magazines in the US. He stood to make considerably more money than in the previous year.
As part of the gymnastics team I was traveling a lot to our competitions. Dad and his cameras would make it to a few of them, depending on his work schedule and the distance to the events. Even in this final year of his service and as a high ranking NCO, he was stuck on a rotating shift. It was not uncommon for the highly classified work that he did. But it did make it more difficult for him to cheer for and make pictures of my friends and me.
My two best friends were also seniors and on the gymnastics team. Both were much better than I was. And both were very sexy. Christina was the athlete, being competitive in both gymnastic and in track. She was short and muscular with a tight butt and firm breasts.
Sofia was sexy. She had big boobs and a big behind but she was really good on the bars and had a great floor routine. And, they both were crazy about my dad. It seemed they spent more time at our apartment than at their own homes.
Both my best friends had German parents. And, German was their first language. Both Sofia's parents were German. Her dad, however, was a high ranking NCO in the US Air Force.
Christina's mom was a German lady who had married a GI. They later divorced and she stayed in Germany. Christina did not know her biological father and was not at all close to her stepfather who was retired military, living in Germany.
In spite of all efforts to maintain our family secret, Christina and Sofia suspected that my relationship with my dad had crossed the line. They talked openly about how they would like to fuck my dad, often insinuating that I was fucking him. I had. But only that one time in late January when we had a family fuck that concluded with Mom and I sharing Dad the entire night. We, my family, knew it would not be the last time.
When Dad would accompany the team and take pictures, Sofia would manage to expose as much her sexy body as possible. I must admit, Dad seemed to enjoy all that she exposed. I had seen him touch those big boobs. Sofia definitely liked it. I think that touch is what gave Sofia the confidence to try so aggressively to seduce my dad.
It was so blatant that it embarrassed Dad. He asked me to talk to Sofia; try to make her understand how delicate his position could be. Even though Sofia, Christina and I were all eighteen, Dad's security clearance could be placed in jeopardy by the appearance of adultery - or incest.
At first, Sofia seemed upset but the more she thought about it the more she realized how awkward it had become for my dad - even though he seemed to encourage it by touching her breast.
I tried to hide my jealousy. He had always been my hero. My Knight in Shining Armor. The man I thought was only interested in me - and my mom, of course. I was not ready to share my dad with friends.
Sofia continued her seductive approach to Dad but was more careful about appearances and the obvious flirting - in public places. Our home was a different story. Both Sofia and Christina had started kissing Dad at every opportunity, especially when arriving or leaving our apartment.
One day, after leaving school early, the three of us came in to find Dad sleeping on the sofa wearing just a pair of gray flannel sweats cut-off at the knees. Sofia pulled up a short footstool beside him and teased him with her long blonde hair brushing his face.
Dad woke slowly, blinking and then smiling at Sofia. Her left hand was resting on his bare stomach, just above the elastic band of his sweats. Her right hand was on the arm of the sofa above Dad's head. Dad put his left arm around Sofia, pulling her closer and kissed her mouth while using his right hand to slide Sofia's hand under the elastic waist band.
She did not resist. Sofia wrapped her hand around Dad's cock and slowly stroked it. The waistband slid back exposing her hand job. Dad must have been really horny. A stream of jism shot nearly to his chest. He held Sofia's head down, kissing her as semen continued to spurt sporadically. She squeezed the last few drops from his softening penis and pulled her face away.
"You like?" she grinned.
I was shocked but really turned on. Christina started applauding and I joined in. It is what it is. My dad doesn't mind being shared. Oh well. There was no claiming that he was the only one fucking me. I had to accept that he would fuck other too - other than Mom and me, that is.
"I could use a wet bath cloth and a towel," Dad said to no one in particular.
I went to get them and returned to find both Christina and Sofia naked.
Dad cleaned away the evidence and sat up on the sofa while my friends pulled off his sweats. They rubbed his face with their tits. He seemed to especially enjoy the feel of Sofia's big titties on his face. He would suck one nipple then the other while burying his face between them when not sucking.
