Convincing a guy to sleep with you isn't hard, convincing a guy to sleep with your boyfriend while you finger yourself? even more difficult, but the payout is fabulous.
Step 1. Get your boyfriend in a position it's hard to get out of. Step 2. Put his cock in your pussy. Step 3. Brag about how many guys you're cheating with while he tries to squirm away.
The bad news is your boyfriend saw your audition and wasn't happy. The good news is, about 500k redditors saw your audition and jerked off all over the place. It's OK to be a slut.
He has bigger muscles, bigger balls, and a bigger cock than your boyfriend. The tingles you feel right now are Mother Nature instructing your body what it needs.
