Play with his chest

"I wonder how sensitive your nipples are?" you ask rhetorically, "Let's find out shall we?"

"Stay away from me," shouts Benz as he tried to break free from his bonds.

You ignore him and move your free hands to play with his still clothed nipples. You twist and tweak the nubs until they were hard and erect.

Benz stops struggling as you continue your ministrations, his face covered in discomfort at the feelings suddenly overwhelming him.

"Don't you like me playing with your nipples?" you tease him as you forcibly tug at his already sore nipples.

"Of course n-not," he squirms in position and shakes his head stubbornly.

"Too bad," you tell him with a large grin on your face, "I like playing with them."

You give his nipples a couple more pulls before cupping his man boobs in your hands and squeezing them like you would with any woman. He has amazingly hard pectorals muscles that are firm to grope and touch.

"Fuck, babe. You have amazing man boobs," you exclaim as you continue massaging his ample chest, "It's so plump and firm. I'd love to take a bite."

You decide it's finally time to see the goods. You push up the frilly pink bra and expose his beautifully sculpted chest. Unable to control yourself, your mouth latches on his right nipple and suck on it, applying just the right amount of suction to making gasp out in surprise and pleasure. Your other hand busies itself with Benz's other nipple, repeating the earlier twisting and tweaking motion at an intensified pace. Not satisfied with just pinches, you start to bite him and nibble softly around the areola, marking him as yours. You alternate between both sides of his chest, lavishing attention to each one with your mouth and fingers.

Soon enough, Benz's nipples are painfully erect and red from all the attention its been given. Interestingly enough, his nipples were not all that was now erect.
