Susan blows you in front of her boyfriend

"Well you're certainly ready, John," Susan says as she slides a soft hand up and down your shaft. "It looks my hubby here needs some encouragement though. Maybe this will help him," she says as she lowers herself to your knees and stretches her mouth as wide as possible and takes your huge cock into her mouth.

You avoid looking over at Susan's boyfriend as she sucks your cock, but you can see his stroking his cock as he watches his girlfriend be shared with another guy for the first time. As a man who's watched his own slutty girlfriend get used, you don't blame him for getting excited by the show. it's far more exciting to have a slutty girlfriend than a prude.

Susan is having fun straining jaw on your huge cock. She's found herself fantasizing about blowing you all week. She wanted to prove to herself that she could do it. She even watched some "how to suck a huge cock like a pornstar" guides on YouTube in preparation for this moment. And like a pornstar she's using a lot of spit to make her bj feel amazing.
