Linda and I have roomed together since college. Both of us have done fine professionally but have been less lucky in love — unable to find a steady boyfriend.

Awhile back we spent a weekend by the beach. Saturday morning in our hotel room, as we got ready to go to the beach, Linda told me about a date with a guy who told her he wanted to see her get herself off. We’ve talked a lot about masturbation over the years, and I’ve learned a lot of techniques from her. So I asked if she did as her date asked.

“Yes,” she said. “I’d never done anything like it before. God, was it erotic!”

I asked, “Did the guy just watch or did he get off too?”

“He just watched, but as I was enjoying myself, I saw him get hard. We made love afterwards, and he came almost immediately. I came almost as quickly.”

Linda asked if I had ever made myself come in front of someone. I said no, but I thought it would be hot.

We lay on the beach till three, then returned to our room to figure out what to do that evening. After we took our swimsuits off, I lay on the bed facedown with a towel around me, texting friends also at the hotel to see what they were doing. Linda, lying on her back on the other bed with a towel over her crotch, said, “Gee, I’m horny.”

I glanced over and saw her move her hand under the towel between her legs. As often as we’d been naked together, I was mesmerized by her breasts, with erect nipples. I texted for a couple more minutes, then glanced over again while I told her about the texts. Her hand was still under the towel, with only her arm moving, as she rubbed herself slowly.

We talked about what we could do that evening. I said nothing about Linda touching herself. I didn’t know if she was just teasing herself or what. I went back to texting for a couple more minutes, then was shocked to see that Linda had removed the towel and was rubbing her clit with two fingers in slow circles. She had her eyes closed and was licking her lips. It was not usual for her to do this in front of me.

I went back to texting but was aroused, and the next time I looked at Linda she was in full masturbation mode — knees raised, legs spread, watching one hand move rapidly over her clit, kneading a nipple with the other. I was getting very turned on watching, but I didn’t say anything. I didn’t want to disturb her. Her legs slid farther apart, and she began to thrust her hips ever so slightly into her hand.

I wanted to touch myself, but I merely watched Linda. Her face reddened and her breathing got more rapid, and she rubbed herself harder, for another couple of minutes. I loved the way her breasts jiggled. When it looked like she was almost there, she looked over at me, her face flushed, with a look of pure lust. Was I turned on!

“I’m going to come,” she rasped. She closed her eyes and seconds later arched her back. Her toes curled and she came hard, for a good half-minute.

Before I could speak, she leapt up, grabbed her towel and said she was going to shower. Hearing the shower go on, and still in shock, I removed my towel and slid a finger in my pussy. I began to gyrate my hips back and forth, fucking my hand, lost in the feeling, thinking of Linda’s tits bouncing and her hips rising to fuck her hand. My pussy clenched.

My head was facing the bathroom door. As I neared climax, the door opened and Linda entered naked. Seeing me, she stopped to watch. Smiling, I said, “I’m so close.” She sat on the bed and kneaded her nipples. “Will this help?” she said, and then spread her legs for me. “I want to see you make yourself come.”

I was never so turned on in my life. I gave a nipple a hard pinch, then closed my eyes and grunted as pleasure overtook me. I opened my eyes to see Linda staring at me. She said, “That was awesome.” She got the conditioner she’d come out for, then returned to the still-running shower. I lay there content, knowing I wanted to do it again with Linda. And that night we did.
