My [M27] birthday weekend with my GF [F31] and FWB [M30s][Chastity][Cuckold][Femdom][FM]

Background:

My girlfriend (Harley) and I have explored cuckolding pretty early on in our relationship. She has since slept with about 5 guys. We’ve only had one guy willing to have me present while I was there, but he couldn’t keep it up. About a month ago, we agreed that I could not fuck her until I had lost 20 lbs. for the first week, I wasn’t even allowed to sleep in the bed with her. The couch became my new bed. It wasn’t bad, considering she let me sleep in the bed while she stayed over and fucked her current fwb.

Day 1:

This started Friday afternoon. I got off work and she was waiting for me at home. She ordered me to get naked and put on one of my thongs. We climb into bed and she slowly strokes me throw my silky underwear for 30 minutes. Harley got pretty worked up and ordered me to get between her legs. I eat her out until she cums and pushes me away. She’s typically a one and done gal, but tonight she had different plans.
