“Well then, let’s go” Krista grinned, taking him by the hand and leading him over to the pull-out couch on the other side of the room. She lowered herself down and her legs folded up underneath her. Mark sat next to her, and smiled nervously.
“This is so weird,” he chuckled, “I don’t think I’ll ever get used to this.” He added. Krista laughed in agreement.
“I know what you mean, you look old enough to be my step-mother!” She smirked.
“Oh is that where we’re going is it?” Mark said slyly, “a little role play? You my troublesome step-daughter or something?” Krista returned his sly expression.
“Or perhaps I’m gay, and I’ve come to you for tips on pleasing my girlfriend?” She giggled.
“Oh I like that idea!” Mark grinned, “for starters if you want to seduce a man, you need to get those lovely girls out!” He said, nodding towards her impressive chest.
“My boobs?” Krista acted surprised, “well if you think it would help” she said coyly. Slowly she peeled off her top and bra. Soon she was kneeling on the couch topless.
“Like this?” She asked. Mark couldn’t tear his eyes away from Krista’s impressive new bust.
“Very good!” He said as he reached out and gently brushed his hand over one of her breasts, “now if you want to make your girlfriend feel good, you need to start with the nipples!” He said, trying to sound informative. Slowly he leaned towards her, and lightly grazed his tongue over one of her nipples.
“Oooohhhh!” Krista squeaked in surprise, “those are more sensitive than I’m used to!” She grinned happily. Mark continued to lightly tease her with his mouth, moving from one breast to another. After a few minutes Krista lightly pushed him away.
“I think I understand” she said, still amazed at how much more sensitive this girls nipples were than her own, “could I try it on you?” She asked.
“Oh but of course dear” Mark replied. He got onto his knees, and expertly unzipped the back of his dress and pulled it off over his head. Next he removed his bra, allowing his new tits to hang free. Now he was just kneeling on the couch in his panties and heels. He arched his back slightly, pushing his boobs forwards. Krista acted hesitant, leaning forward with her tongue out, and gave his new, larger nipples as tentative flick. Feeling the need to take control, Mark gently placed his hands on either side of her face and pulled her forward.
“You need to be more confident dear!” He said “chose one and hold it in place if you have to!” He commanded. Krista was shocked at how easily Mark had slipped into the role, but she was also finding it was turning her on. She reached up with her hand and cupped one of his breasts, and firmly dragged her tongue across his areola. Mark let out an involuntary moan as her soft tongue pressed against his flesh.
“Good girl!” He said looking down at her and meeting her eye, “just like that!” He purred
Krista felt a warm thrill run through her at his praise, and began to suckle his breasts in earnest, and she could actually feel his body tensing with every lick.
‘Seems like he’s as sensitive as I am in the boob department’ she thought. Finally Mark could take no more and he gently guided her away from him.
“Very good dear” he said with a grin, “I think it’s time for the next part of the lesson!”
