Catching up with the biggest cock

She unclipped her bra and her lovely big breasts were free. The amazing thing was that even though she was big there was hardly any sagging to them at all, they seemed to blossom from her chest like lovely big soft mounds with amazingly large nipples that were hard. She climbed back onto the bed and moved up until she knelt above him then she slid her hands down and slipped a finger from each hand into her pussy and pulled it open and looking down at Tom she said, ‘I’m going to have that lovely cock in my pussy’. Tom’s eyes were wide open staring at her and I could see by the look on his face that he thought that all of his birthdays had come at once. His cock gave a jerk and then she looked at me and said, ‘Help me please’.
I reached down took hold of his cock in one hand and guided it until the large head was rubbing just between her lips which were actually dripping with her juices. She lifted her eyes from Toms’ and looked at me and then she slowly lowered herself down onto it. I saw her expression change as it entered her, as I’d seen that expression before when I’d slipped inside her and knew how she loved it. Then as she slid lower and more and more of his cock went inside her the expression changed from lust and for a second one of pain then her eyes flew open wide and she gasped and she said, ‘ooooh god yes’. Her pussy lips were trapping my hand against Toms body and I realised that she’d actually somehow got all of him inside her. I looked down at Tom and his face was red, his lips were curled back like an a****l when its snarling as he muttered’ , oh she’s taking it all’.
Chris started to moan and I knew that she must have been flexing her pussy muscles around it getting used to being so full and for a moment I sort of regretted it because I thought that maybe she wouldn’t be interested in letting me fuck her again after having such a huge cock inside her. She then started to move slowly up and down flinching a little each time that she moved down and it went back insider her. But she must have got used to it because quite quickly her body began to increase it’s pace. I heard Tom murmur, ‘Oooooh I’m going to cum’. I guess that the excitement had just got to be too much for him, but Chris heard him and said, ‘Yes go on baby, fill Chrissy’s pussy’ and she moved a little faster.
