John and I had just been at the gym playing a very long game of one-on-one. Since we were both fairly decent amateur players, it always took us forever to have one of us win by four points, the margin we set for quitting. That was fine by us, however, because we figured Kathleen and Denise had gone out on one of their regular shopping marathons. One of the big advantages of becoming a foursome was that John and I didn't have to spend much time at the mall, anymore!
Instead, when we walked in the door, we found Kathleen and Denise waiting for us. They were in the bedroom chatting, but shut up as soon as we closed the door - so we knew something was up. Both of us winked at each other - usually when something was up it meant a hot afternoon or evening of sex!
When we walked into the bedroom Kathleen greeted us with a cheery "hello", but Denise just waved. She had a sort of glassy look in her eyes, and both John and I immediately asked if she was okay. "She's okay, boys" said Kathleen, "but we've got a surprise for you two, and part of it involves Denise not giving it away so she's not going to talk right now, okay? Now, sit down over there in those chairs, and be patient."
John and I move to sit in the two arm chairs near the bed. I have a very large bedroom. My apartment complex went "condo" last year, and after I bought my place the first thing I did was to knock down the wall between the two bedrooms, the third "bedroom" being my home office, and combine them into one very large room with a bathroom big enough for a garden tub. Kathleen loves the tub, and I love having enough room in there so that we don't run into each other. The chairs are very comfortable, and also a great place to be a voyeur when the other two or three are having a hot time on the bed!
"We've been working on this surprise for months now" began Kathleen, "and we're about ready to reveal it. You two have to promise to sit there and observe until I tell you to move, okay?" Both of us nodded our heads, since Kathleen's surprises invariably involved us getting our rocks off.
"Now, let me explain.. My friend Denise, here, has had a problem for a very long time. As a good friend of hers, of course I wanted to help her in any way I can. So, for the past few months, when you guys believed we were shopping for hours and hours, I've been helping her overcome this problem. I believe she's licked it now, and we're going to show you the results. Show them, Denise!"
With that, Denise stood near the bed, bent down to grasp the hem of her loose summer dress, and lifted up over her head. John and I grinned in anticipation as we saw Denise's rock-hard dark nipples and skin shining with sweat, her pubic hair glistening. Denise must be incredibly aroused, we thought, and then did a double-take as we saw the end of a dildo protruding from her pussy. She must have had all of it inside her, and I could tell from the look on her face now that it made her even more aroused to have us watch. She must be aching to cum, I thought.
"Denise has been cumming since about 8 this morning, John. That's why she won't talk, if she opened her mouth, she'd let out such a moan that you both might guess the secret. And now, Denise, crawl up on the bed and show them why you've been cumming so much!"
Denise turned and crawled up on the bed. When she was on all fours, John and I sat slack-jawed in amazement! There, protruding from Denise's asshole, was another dildo! Not, perhaps, as big as the other, but since Denise had always felt pain when anything other than one of Kathleen's slender fingers probed her ass, the thought of anything in her tight hole was astounding. It was also, of course, a great turn-on. John and I simultaneously unzipped and removed our pants, and our underwear, so that our huge hard-ons could spring free.
"I see that you're intrigued by this, " Kathleen grinned, "Every Saturday for months now, Denise has been practicing. First I got her to take two of my fingers, sliding them in and out covered with lube, and then we moved to a really slim vibrator. I wish you could have seen her cum the first time we did that! Over the last couple of months we've increased the thickness of the rubber cock we put in her ass until she felt she was ready to give you guys your surprise.. And today's the day! Okay, Denise, you can tell him now..." Kathleen turned to the bed, and pulled both dildos out of Denise's holes.
