Heather's heart raced as she watched Emma sit on the bench, and open her legs invitingly.  She made her way over there, and squatted, letting her masterpiece of an ass fill her shorts out as she slowly went down.  Her face was now eye level with Emma's shaft.  "Wow, okay.  Maybe... Just this once.  But don't expect me to be that good."<br/><br/>Without much hesitation, She gently sucked the balls between her lips, and tasted the sweat cascading downward.  "Mmmn," She then slowly ran the top of her tongue from the base, all the way up to the tip, and circled around the glans as if it were an icecream cone.  Holding the base, and squeezing slightly with her left hand, Heather gazed up into Emma's eyes, making non-blinking contact as she slowly slide the monstrous rod between her warm lips. "Annh."  she hummed, as her head bobbed up and down gently, while stroking the bottom part with her hand still.  Heather pulled the tip out of her mouth, with a 'plop' noise, still stroking it, and smiled at her.  "Like this?"  Her panties could be seen as soaking, as her virgin pussy was drenched underneath the tight thong.
