Always a pleasure to see a big clit pulsating at the moment of orgasm. I love the fleshy prepuce on her clit, be a pleasure to roll it right back until all of her glans is sticking out and then lick the underside around the frenulum.
That needs some sildenafil cream rubbing in, pull the prepuce right back to expose the glans completely and rub a pea sized blob of cream in. Wait 25 minutes and then masturbate. Works well on some women apparently.
