I visit an Asian masseuse who gives a great massage and then afterwards will stick her finger in my ass and do prostate massage while providing a happy ending. It's not "pegging" per se but damn close. Have seen her many times, and each session she gets a little more aggressive. Last week she got me on all fours and forcefully finger fucked my ass for about 20 minutes and several times went as deep as she could reach and wiggled her finger to rub my prostate. She was owning my ass, while milking my cock backwards towards her. It was so intense I did not think i was going to be able to maintain my erection, never mind cum. But 20 minutes in she started cooing and saying "yes you like me fucking your ass, you're going to cum" and sure enough a minute later I grunted out the biggest pile of cum in a decade.
