Call her back for another round

You keep your eyes locked with Martina's while her friend keeps blowing your cock. There's uncertainty but also a bit of curiousiy written on her face.

Finally she steps back into the room again, approaching reluctantly as you motion for her to come closer. Then she's back to her knees again, with your strong fist holding her down by the hair. She doesn't look too happy about it, but you guess she's kinda 'taking one for the team' to keep you from hurting her lover.

You reward her obedience with a taste of your cock of course, letting her clean it of all the saliva and precum left behind as you pull it free from her lover's lips.

She groans a bit around your fat shaft, but gets to sucking you with surprising enthusiasm. Most likely she's just wanting to get you off as quick as possible, and without any need for ****.

It's not long before she's managed to drain you of another batch of semen, and she even swallows it all with just a little dribbling out the corners of her mouth.

She didn't count on your exceptional endurance though, and watches with a bit of shock on her pretty face as your member returns to full hardness within a couple of moments after she let it slip from her lips. Anna, at the other hand, shows a different attitude entirely as she happily takes your hardon right back into her mouth again.
