I walked into the bedroom and saw Diane and Cathy sitting on the bed. Diane was naked and Cathy was topless. Diane was fondling one of Cathy's breasts and sucking on the other. Cathy was rubbing the back of Diane's head and had a bemused look on her face.
As I walked into the room, Diane lifted her head from Cathy's tit and faced over in my direction.
"Justine was right Aaron, Cathy really does have big tits, and boy are they fun. I can't wait to see how she tastes."
"Don't you think you should ask her first?"
"Oh yeah. May I please taste you Cathy?"
As she was saying this Diane had continued massaging Cathy's tits and was talking into her neck right under her ear.
"As you consider it Cathy, you might want to taste her too. Diane has a unique flavor. I don't have a lot of experience, but she is delicious."
Cathy looked up at me and said, "I've never done it with a girl before Aaron. What do I do?"
"Just relax and lay back. Diane will take charge. She and Justine do this quite often. I can't be ready all the time after all."
Cathy just sighed and leaned back onto the bed. Diane reached over and pulled Cathy's slacks and panties down and off. She then knelt between Cathy's legs and began to nuzzle between her thighs.
I took off my clothes and went to the other side and climbed onto the bed. I took over on Cathy's tits where Diane had left off.
It didn't take long for Cathy to have her first orgasm. I had barely moved to the other tit when she started gasping and shivering. She let out a wail and shuddered.
Diane moved out from between Cathy's legs and I shifted her over to the far side of the bed so I could give my attention to Diane.
"Oh Aaron, she is so different from Justine. She responds at different areas and the taste is just as nice but not the same. I could tell the difference even if you hadn't had Justine shave."
"I know dear, every woman is unique. It depends as much on their introduction to sex as much as it is physical. All Cathy has known is rape. Any tenderness shown to her will reap large rewards. How did you like your first experience with a woman, Cathy?"
"That was so gentle, you were very kind Aaron, but Diane was coaxing me instead of driving or demanding. I could just relax and be at peace. Thank you Diane, that was wonderful."
"You are welcome, Dear, maybe you would like to clean me up after Aaron is done. Justine and I both love cream pies."
While this conversation was going on I was moving Diane up onto her knees and positioning myself behind her. As far into her pregnancy as she was, missionary position was just not comfortable. She was already very wet from licking Cathy and all I needed to do was rub my cock in her substantial juices and enter her.
As I started to move in her, Diane rocked back an forth with me. After long experience with Diane I varied my speed to coincide with the spasms within her vagina. Doing this I could bring her almost to orgasm and then keep her at that peak to intensify the climax.
Cathy roused herself enough to reach over and play with Diane's little titties. She shifted herself around so as to lick the aforementioned titties.
"You might want to be careful Cathy. Those puppies are primed and loaded."
"What do you mean Aaron?"
"I mean that Diane is already lactating; unless you want a taste you might not want to suck."
"Ohh, that sounds naughty, I just have to give that a try.
Putting action to words Cathy grabbed a nipple and proceeded to suck.
"Have you tried this Aaron?"
"Sure he has dear", Diane said, "but he doesn't like it nearly as much as Justine does. Justine says that by drinking my milk it will put a part of me into her child. I don't really subscribe to that theory but that's all right, I enjoy feeding Justine anyway."
Cathy looked up momentarily, "This is such a sweet taste; not at all like cow's milk. I love it."
"You are welcome to come back anytime Cathy, I'm not due for another month and Justine should start lactating soon as well. OOOOHH AARON!! YES YES YES, HARDER, FUCK ME HARDER."
After her first orgasm, I lay Diane on her side and spooned in behind her for a long leisurely fuck. This was much more comfortable for her but she usually didn't have time for this when we started; she wanted the first one to go quicker than this position allowed. As we moved together Cathy was shifting around and touching Diane everywhere, to include where we were joined. I could feel her fingers and lips there while I reached up to fondle Diane's tits. Cathy kept her concentration on the juncture of us as I started to speed up and stayed right with us as both Diane and I climaxed.
When I pulled out Cathy even cleaned me up with her mouth.
"Oh wow, what a taste."
Diane rolled onto her back and raised her knees. "Try it down here Cathy, Justine and I love the mixed flavor of Aaron's cum and our juices."
