Do a full creampie by edging yourself, then ask her to standup and take a few steps. Watch the cum dribble down her beautiful legs or drop onto the floor... Fark, it's the stuff of fantasy!
Personally never been a fan of CIM, but one time I managed to go from BBFS straight to CIM with T Alin at GC. I still remember the feeling of her hair extensions on my hands while I held her head in place for the CIM. Now that was a real PSE. I'd say I did even better than porn cos I wasn't desensitized like the porn actors, didn't need to wank myself off to cum.
