My fiancé [F] became a couple’s cake while I watched [MFFM]

This is my first post. It’s a brief, informal summary of an experience I had several years ago. The detailed version is part of a memoir series that will be published to Kindle.

After college, my girlfriend and I began to explore our sexual horizons together: lingerie, blindfolds, light bondage, dildoes, etc. It was all fun – how could it not be? (Riley is a rare beauty – she’s a Yogi with a slender body and long, toned legs. Her ass is round, she sports a natural 32DD bust, and has light brown hair with hints of copper.). But the excitement of each step wore off quickly, leaving us searching for the next rush.

Through a messaging app, I became friends (online only) with a redditor named Jack. He and his girlfriend had followed a similar path to sexual liberation, and he raved about the threesome experiences he and his wife Mila had recently shared.

Riley and I began to role-play group sex, especially situations where I and another person (female or male) would dominate her. This fantasy elevated our sex for a long time, and eventually we dirty-talked about doing it for real. But once the sex was over and the steam dissipated, it never sounded like such a great idea. Neither of us wanted to meet Randos online, and the thought of getting sexual with friends was too taboo for either of us.
