Switch: Billionaire's Dungeon Part 4 (bdsm hardcore new adult older younger first time dp double penetration erotica)

When Becca arranges a secret rendezvous with her fellow, older submissive, Nick, she knows Master will be displeased if he knew. What she doesn't expect is for Master to find out...which is exactly what happens next.

Obviously, a good master can't let his submissives do whatever they want, and dominant alpha male David considers himself a very good master. During their next session, he has a special lesson planned for young, naive Becca, which involves Nick and double the fun.
