I want to make sure my girlfriend Rue is receiving maximum sexual pleasure in our relationship. I ask her if I can test out some thesis I have devised~ for instance… if we build her arousal up slowly, then her orgasm will be extra powerful. We start out with kissing, caressing and breast play, then move into fingering, vibrator + barbell stimulation, and finish with a long session of oral! Isn’t science fun?
