I was horny long before this, but having Beth standing so close to me, nearly naked and eager to please me, there was no stopping me now. With both hands, I reached out and grasped her breasts. Ever since I saw her puffy nipples I'd wanted to squeeze and torment them and now I was going to do that. First I squeezed tightly at the base of her breasts. She sighed loudly as I gripped them tightly. Although her breasts were probably a little less than a B-cup, I was still able to slap them together a few times before I moved my attention to her nipples. They'd already begun to harden so they were easy to grab. I gave both a hard squeeze between the thumb and middle finger of both hands and twisted them as I tugged. They both became extremely hard and the color darkened. Beth whimpered as I mauled them but didn't try to back away or get me to stop. She did, however, pull off my robe and part her legs a little more. I looked down and saw a stream of clear liquid making its way down her inner thighs.
Just as I reached a hand between her thighs and pushed several fingers up between her pussy lips I heard a knock on the sliding glass door a few feet away. It was Pia. The door slid open and she stepped into the room.
"I was wondering why you hadn't come to the pool to get me!" Pia exclaimed. "Now I know why. Oh, she's a yummy one, she is!"
I wasn't really sure what to do other than introduce them to each other and then see what happened. "Pia, this is Beth, my new maid. Beth, this is Pia, my pool girl with benefits."
Beth was obviously startled but so aroused she remained still and said nothing.
Pia continued, "Very nice to meet you, Beth. I look forward to getting to know you very well. Maybe I'll be able to give you a few pointers on how to keep Brent happy, not that he won't guide you along the way. He knows what he wants and he takes it."
I interrupted. "Pia, you know that's not entirely true," I said as I pushed two fingers inside Beth.
"Well, once he finds out what you're willing to do, he'll take it whenever he wants," she responded. "Like, when we first got started, I was afraid to let him take me anally, so he only teased me with his fingers and small toys, but once I finally gave him the go ahead, Holy Mother!"
"Tell the whole truth, Pia," I said as I continued fingering Beth's soaked pussy.
"Okay, okay. After I told him I thought I was ready, he started slowly, but I could tell he was getting a little frustrated because I was still tight and he couldn't get the head of his cock inside, so I told him just to take me. It hurt for an instant, and then it started to hurt in a very good way, and after he started going in and out, it started feeling oh so good. When he finally stopped fucking me that time, I was sore for days, so we made an agreement that he'd only butt fuck me during my period. So, once a month, he rapes my ass and I have to sit down gingerly for a few days following. By the way, it's only a few more days 'til my period starts."
I smeared some of the wetness from Beth's pussy onto the rim of her ass hole and teased her.
Pia watched intently, slipping her hand inside her skimpy white shorts. "I am so wet! Brent, why don't you let me show her one of the things you like to do with me?"
