was lying on her back on the bed. She was topless in a pair of panties and had each hand tied to one of the bedposts. She had a necktie double wrapped around her eyes. Her tits were huge, at least D cups Zack thought. Brian was on the bed massaging her thighs and Diane was just lying there crooning about how good it felt. Brian had the TV on some kind of music station to give themselves some background noise. Zack stripped to his boxers and came over to the bed. Brian motioned to him to get on the bed as he got up himself. “Where you going honey?” Diane asked. “Just relax babe, Daddy’s going to take care of you”. Zack sat down on the bed in front of her spread legs and started running his hands up her thighs. She relaxed and went back to cooing at Brian. Zack immediately moved his hand from her thighs up to her breasts. Julie had nice breasts but nothing like the size of Diane’s. He spent some time squeezing and playing with her nipples which started to make her squirm. Zack moved his hands from her breasts back down to her panties. She instinctively lifted her hips and he pulled her panties off. Her pussy had light blond hair which was a contrast to the dark patch he was used to with Julie, so he spent some time running his fingers through her bush and spreading her lips. One thing became evident very quickly – Diane was a moaner. Julie was fun in bed and certainly wasn’t quiet, but Diane was already starting to squirm and make all kinds of moaning noises. This was something Zack wasn’t expecting from Diane and it made his cock rock hard. Once she really started making noise Zack sat up and removed his boxers. Brian was shocked. Zack’s cock was huge. All this time they had been discussing the rules it never occurred to them that one of them might be endowed enough to give them away. Zack’s cock hard looked like it was twice the size of Brian’s – there was going to be no way he could stuff that thing into Diane without her noticing a difference. But the die was already cast, and there was going to be no way he could stop Zack now. Zack looked over at him and saw the alarm on his face but just motioned to him that it was cool. He got back on the bed and started massaging Diane’s pussy to get her ready. Brian was not a big foreplay guy so he knew Diane would appreciate this, especially considering the monster that was in store for her. Diane was moaning out load and squirming all over the bed. Brian said “That’s it babe, let me get that pussy nice and hot” in an effort to play it up. Zack was intently manipulating her pussy with his fingers and she was squirming and pulling against her bounds like a crazy woman. Zach went back to sucking and playing with her nipples and she went nuts. Zack got back down between her legs and gave her pussy a series of thorough licks, all of which made her cry out. Once we was satisfied she was slick enough, he slowly parted her pussy lips and started to put the huge head of his cock inside her. Brian could tell she was hesitating at the size of his cock trying to enter her. He said “Baby, you feel so tight – try to relax.” She panted back to him “yes, I’m tight, I’ll relax, just go easy”. Zack took his cue and moved his cock back and forth to get slick with her juices and then started to slowly push it into her. Brian kept coaxing her “Just relax babe, you’re still tight, just relax that pussy”. Diane was breathing in hitched breathes and saying “trying to relax, easy – trying to relax” as Zack worked more of his huge cock into her. Brian had to get in closer to actually see this thing going into his wife. He didn’t think it would but he could see her pussy stretching to accommodate Zack’s huge dick. He eventually got the whole thing in and Brian said “Atta girl, that’s it, I’m inside you honey”. Then she started to moan. She had never had a cock stretching her out like this or touching her this deeply before. Once
