Mom with my friends!

I used to play baseball in high school and played in summer league. We would go to games and since we had a van, we would take equipment and 4 of my teammates/friends would go with us! My mom would drive and usually sat in stands. I noticed that sometimes she would be missing and I always thought she was at concessions. During one of my games I hurried to van to get a bottled water and heard sounds coming from van! I peeked in rear window and saw my mom on her back with a friend who had a brother on the team and there was another guy kissing her! I went back to dugout and continued the game. Later I recalled that many times during practice she would go to van and some of my teammates would be missing for periods of time as well as the coaches. I think my mom was the team whore and everybody but me was fucking her! I never confronted her and gave up playing baseball! Never confronted her or told my dad!
