My first 'soaking' experience was with an affair partner. She was a 'good Catholic girl' gone bad - I seduced and corrupted her to the core. During the earliest phase of our affair, Marie held to this odd idea that certain things weren't actually sex, or cheating, like a blowjob, me going down on her, and 'soaking'.
Marie would mount me, cowgirl style, guide my cock inside, then just squat on me, otherwise motionless - no thrusting or pumping in that hot wet pussy - she diddled her clit with my cock buried deep inside her. After she got herself off, I almost always lost it, trying to remain perfectly still while little spasms of orgasm drained my cum into her.
