Kat meanwhile trailed kisses down my neck, down my chest, across my stomach. She took me into her mouth and made my knees buckle. A wonderful spring wound tighter and tighter within my balls, but Kat took gentle hold of them and pulled them downwards, and the feeling diffused before I exploded.
Now Deana dropped down as well and took turns with Kat in kissing my shaft. They both arrived at the tip at the same time, and ended up kissing each other with me in the middle. Their eyes widened in surprise, then two tongues crossed and parried with my shaft as a hostage between them. They fell back, and I could see the unspoken words in the moonlit air: "I didn't know ...", "I didn't either ..."
They pushed me down on the towels. Kat straddled my face and lowered her pussy towards my mouth. I breathed in her scent, strong and unfamiliar to me. I parted the trim, almost feline, fur and tried to see in the moon shadows what I was expected to do here. "I haven't done this before, Kat. Tell me what's good for you."
"You haven't done oral on a girl before?"
I hesitated. It didn't feel manly to admit my lack of experience, but I didn't want to disappoint them. "Actually ... all of this is new to me."
Kat turned to Deana. "It's his first time! We get to teach intercourse 101 tonight!"
Deana leaned close and stroked my cheeks. "That's really special, Ben. I'm glad we get to be your TAs."
She urged Kat to raise up a few inches so I could see her pussy. Deana gently parted Kat's folds and gave me the introductory lesson. "These are her labia and this is her clitoris. Kiss her and lick her from here to here." Her finger traced a path and Kat sighed. "Go gentle on the clitoris until you get her excited. This is her vagina, you can tongue her there as much as you like." Her finger slipped inside in demonstration, and Kat squeaked, "Deana!"
Kat lowered herself over my mouth again and I had my first taste of woman. It was musky, fresh, and heady. Most of the guys didn't like going down on their girls, though some bragged incessantly about it. At this point I felt I was going to dedicate my life to it.
"Oh Ben, that feels so good! Just keep it up. Yes, just like that. Oh, Oh ... you're so good." Deana swung astride me behind Kat. She reached around and started playing with her nipples. Kat ground her pussy into my face, which I took as the signal to get more aggressive. I formed my lips around her clitoris and started sucking on it. That was apparently the right thing to do, since she clamped my head between her thighs and started screaming.
I hung on and kept working with my tongue and lips as she bucked above me. I started worrying about dislocating my jaw if she bounced too hard in her excitement. Fortunately, Deana held her tightly and kept her in place for me. Eventually she pulled up from me, gasping, "enough, enough." She slumped in Deana's arms, breath shuddering through her slight frame.
"What happens if I'm alone with one of you and there's no one to protect me?" I inquired, adjusting my jaw to see if it still worked. Kat started laughing and fell down beside me, hugging me tight. "Oh, man, Ben. You'll have to take some self-defense lessons. You're just a natural at this."
Deana scooted back until she was positioned over my penis. She rubbed the tip against her pussy lips; I felt the lubrication begin to ease the way into her passage. How was I going to fit inside? She didn't seem wide enough to take me in. As she eased over the tip, I felt her stretching, holding me tightly but still letting me slide in. Slowly she sheathed me, accommodating my girth and length. We were joined, fitting perfectly. The sensation of sliding into her felt so right. My own hand would never feel that way; these parts were made to fit each other. Did I mention my tendency to nerdy thoughts at inappropriate moments?
Do you remember your first time? I wanted to fix every detail in my mind, to keep my first time fresh forever. I felt the walls of her passage sliding back and forth over me. They were more textured than I had expected, and the feeling more intense. The sweet catenary curves of her breasts bobbed in time with her motions. I put my palms against her nipples and felt them rise and fall as she rocked. She sighed, and leaned forward to offer them to my mouth.
I suckled on first one breast, then the other. They were soft and warm; the nipples were stiff and urgent. This slowed her rocking, so I placed my hands on her hips and thrust into her from beneath. I liked this because I could control the pace and slow or pause if I got too close to the brink. I wanted this to last until I could feel her come while I was inside her.
Kat had been lying beside me this whole time. She now leaned in to kiss us, first me then Deana. We tried to do a three-way at the same time, but the angles were too challenging. She crawled around behind Deana, and then I felt her tongue. She started licking at my balls and traveled up my shaft to where I disappeared inside Deana. From the wide-eyed astonishment on Deana's face this was as surprising and incredible a feeling for her as it was for me.
Kat urged Deana to get up, and we parted with a wet plop. She positioned Deana facing backwards, and took my penis in her hands. She took it in her mouth and sucked it a few times, then positioned it at Deana's opening again. As she eased her down my shaft, she planted a lingering kiss on Dean's clitoris. After I was fully inside, she alternately took my balls in her mouth and licked Deana's clitoris. Deana reclined in my arms where I could reach around and play with her breasts, while Kat made love to our joining.
Soon I felt Deana trembling in my arms and making more and more urgent mewling noises. She grasped my forearms tightly and went rigid. She held that pose for a full minute, and then ... "Oh ... my ... god!" She started thrashing in my arms. I held her tightly so that I didn't slip free. Her vagina clamped tightly on my penis, something I wasn't yet schooled in. That pushed me to the edge, and with a few quick thrusts I buried it to the hilt in her, pumping three, four times, then just holding it until we both stopped shaking.
We subsided into a puddle on the ground, with Kat joining us for a group hug. "Thank you for a really memorable first time," I said.
"It was a first time for us, too," said Deana.
"How do you mean?"
"That was my first time with another girl, and my first time with three people. I didn't think I would enjoy that sort of thing, but it just happened." Kat nodded her agreement.
"Will it happen again?"
"We'll have to see."
Kat arose, being the one on top. "I think it undid all the coolness we got from the swim." She was right, we were as hot and sticky as ever. "Let's go rinse off again."
Deana and I were still joined, and I felt a little sadness as I slipped out of her as she stood. That truly marked the end of my first time. We walked hand in hand back down to the shore.
The water was cool and clean after our sweaty exertion. We stayed close this time, and rinsed each other off with long kisses and longer touches than were strictly necessary. I cupped both of their asses as they stood in the water and pulled them close, and their hands collided trying to reach my penis. I was hard again, and they giggled. "Ben wants extra credit." "I think he wants to make a good impression on the TAs."
Kat jumped up, weightless in the water, and wrapped arms and legs around me. She squirmed around until she located my penis with her pussy, and sank down on it. The penetration was more difficult because the water had rinsed away some of her lubrication, but after a few strokes we managed it and could move easily. "Oh, Deana, you didn't tell me he was that long. He hits bottom!"
I didn't know if it was the position or a difference in size. I guessed if legs and breasts and penises could be different sizes, then so could vaginas. Kat felt different from Deana, skinnier, tighter, more textured. Since this position was a little uncomfortable for both us, I reclined her in the water until she was floating. Deana moved around to support her head against her breasts. In this position, with her legs locked around my waist, Kat could move back and forth in the water gently stimulating us both. After a few minutes of this motion she suddenly clamped her legs and quivered in the water. In this position and this soon, I knew I couldn't come again without a lot more pounding. I felt happy that I'd give them both orgasms, so I slipped out and let the cool water soothe me back to softness.
