Married Best Friend (F27)

So we are a group of friends who tend to travel together. My close friend got married recently and we all were on a trip to the beach. Seeing her in bikini just made it so hot that I couldn't stop thinking of having her under me. Cut to night after a bucket load of drinking most were drunk and out including her husband. We were one of the few left and ended up making out. Proceeded to move to the terrace and tear her clothes out and push it in doggy style. Couple of weeks later got a message from her about her exploring her submissive side which she loves and wants to be one.
