My last GF loved this. We did in a hotel room in front of a large mirror and she just went wild after I'd cum and pounced on me as I fell on the bed behind, blowing me into another oblivion. She was amazing.
Other times she loved to "have me for breakfast" and watch herself giving me a blow job. I wrote a poem on Medium about it. https://bgt00847.medium.com/you-had-me-for-breakfast-1e2e4c00dfaa
I loved her and wish we could make it up and get back together but Covid and about 3000 miles are making it difficult.
