I walked in on my father-in-law while he was getting a blow job from young Tommy, the neighbor's kid. They didn't notice me so I stood back in the dark hallway outside the door. Dad was encouraging Tommy, telling him what a good little cocksucker he had become as he slowly and firmly face fucked him. I was aroused as I watched wanting desperately to join in, so I quietly got naked in the hallway and walked into the room, fully erect. My father-in-law's eyes went wide and he pushed Tommy away trying to hide. I just laughed and helped Tommy to his knees and wagged my big dick in front of his talented lips. Dad watched and began to stroke his own big cock as Tommy sucked my dick. At this point I got Tommy up unto the sofa and he started sucking Dad's dick as began eating his cute little ass. I worked a couple fingers into his asshole and after lubing up my dick I slowly penetrated his virgin hole. I was very gentle, being quite experienced with first time anal sex. I have fucked eleven different men and a half dozen women in the ass. His hole was tight and he became a little scared as I forced my rock hard cock into him. As they all do, he eventually relaxed and enjoined the fullness in his ass. I fucked him well and gently at first, but by the time I came deep in his ass I was pounding him.
My father-in-law painted young Tommy's face with his load and I took a picture. I had taken a few to keep as security.
Tommy took a shower and my father-in-law gave him $200 bucks before he left for "mowing the lawn."
