I lifted them up to my nose and took a good deep sniff and the musky aroma filled my nostrils and I immediately started to get a massive hard on. It w...s so intoxicating and also very exciting as Julie could have woken up at anytime and seen me sniffing and licking at her dirty panties.The White cotton gusset of her panties was quite crispy with a few of her pubic hairs stuck in the middle of it. God I loved to sniff her crispy panties and then lick the crusty part until it becomes wet and slimy. In return, it made Nadir to eat her sister’s pussy with the same zeal and fervor, holding her hips tighter to keep her close to his face. The i****tuous game of 69 in progress for the both participants. Damn!! Nadir was enjoying the taste of the wettest, the sweetest pussy ever much more addictive for any pussy lover. His tongue dipping deeper in his sister’s close trimmed cunt, nibbling action being improved; intensity increasing until every attempt of edging denied and he shoots his nectar. I was rewarded with a guttural groan and a large amount of fluid running over my hand and onto Sarah's face. Sarah released my cock and was lapping away at Dawns pussy like a it was the last meal she would ever have. By now I was at the point where sense goes out of the window and lust takes over.With my cock in hand I lent forward an pushed it past Sarah's mouth rubbing it against Dawns opening, coating it with her juices I wanted, needed to fuck her. As my cock slid into Dawn, Sarah held her. Henderson said firmly. "You both knew you might have an observer at some of your sessions when you signed your contract."Leroy was still tense, but obviously weighing his response. After a few uncertain moments we saw his muscles visibly relax. At last he spoke in a more conciliatory voice."Yes we did agree to that. I am sorry if I overreacted. You might have let us know, doctor, at the beginning of today's session that we were not alone." Ah, but then you would not have behaved spontaneously..
