If it hadn't been for that conversation with Melissa, I would probably never have discovered what sex with another woman was like, and especially not sex with my best friend, and then my sister.
Both Melissa and I are 21, and attend the same college. Actually, we've known each other since the 3rd grade, and have been best friends ever since. Melissa has an older sister, Karen, and I have a younger sister, Cindy. Sharing sister stories was a thing we did regularly.
One day, we met for study time at the campus coffee shop. It was usually more gossiping than studying, so I always looked forward to it.
"Hey, Chris!" Melissa called out as I entered the shop. My name is actually Christy, but Melissa has called me Chris ever since we met when we were eight. "We're over here!" she said, waving me over.
Melissa was sitting at a table that was out of the way, and partly blocked from the other tables by some really large plants. I figured she had something great to dish about and wanted more privacy.
I got coffee and headed over.
"Hey girl!" I said, plopping down in a chair and setting my backpack on the table.
We both had a psychology class together and that was the topic we were going to focus on, or so I thought. Melissa's backpack sat unopened on the floor.
"So, what's up?" I asked.
I took a moment to give her the once-over. Something seemed off, different, and not in a bad way. She was practically glowing and had a big smile on her face. It was like she couldn't wait to tell me something, but was a little hesitant.
"Are you okay?" I asked, genuinely interested.
"Oh, for sure," she answered. "Actually, more than okay."
"So, something good happen on Spring Break?" I asked. We'd just returned to campus from a week off. Both of us had gone home and hadn't seen each other.
"You might say that," Melissa said, a sort of mischievous look on her face.
She leaned closer and spoke softly, "I did something naughty that I really want to tell you about, but you have to absolutely swear to keep it a secret."
Now she had my full attention.
"No problem!" I said. We'd kept each other's secrets practically our whole lives so I wasn't quite sure why she even needed to ask.
"Cool!" she said, visibly relaxing. "You know my folks were gone over the break, right?"
"Uh huh," I replied, taking a sip of coffee.
"So Karen and I had the house to ourselves." She seemed to hesitate for a moment before going on. "We had, well, some great talks and, um, we got kind of deep into a topic I wasn't prepared for."
"Okay," I said, setting down my cup and leaning in. "Do tell!"
"Shit, Christy," Melissa said. "It's so personal but so wonderful."
"You can tell me, Mel," I said, reaching across the table and putting my hand on hers.
She hesitated for another moment, and then I could see on her face that she'd made a decision.
"Karen is a lesbian," she said.
"Okay. That's wonderful for her," I said, not sure why that was so earth shattering.
"She was telling me how wonderful it was, her first time. And, um, she went into some pretty graphic details."
"Sounds like Karen," I said.
Melissa laughed, "Indeed!" She looked me earnestly and placed her other hand on mine. "We didn't just talk about being a lesbian, Chris. We, well, we did it."
"Did it?" I asked. "Not sure what you mean."
"I mean that I had sex with my sister!"
"Oh shit!" I said, before I could catch myself. "For real?"
"Are you disgusted with me?" Melissa asked, a vulnerable look on her face.
"Well, um, uh," I answered, stammering. "It's unusual for sure. Disgusted, no. Actually, a bit curious."
Melissa and I had discussed sex before, of course, even lesbian sex. But neither of us had done anything about it and hadn't been with anyone sexually. I found myself thinking about Karen and Melissa together, naked, Karen's head between Melissa's legs, eating her out, Melissa crying out in pleasure. That was certainly not the reaction I would have expected in myself.
"Shit! That's a relief," Melissa said, visibly relaxing.
"You fucking had sex with your sister?" I said, more a statement than a question.
Melissa nodded. "She just seemed like such a safe person to explore my sexuality with. It didn't seem wrong at the time, and doesn't now even."
We sat for a minute as I let this news settle. My best friend had just had lesbian sex with her sister! I found myself even more curious.
"So, um," I started. "What, what was it like, with Karen? How did it happen?"
Melissa smiled. "She started sharing her first experience, and to hear her describe kissing a woman and exploring her mouth with her tongue started really getting me turned on." She lifted her coffee cup but didn't drink from it. "I asked Karen to show me what it was like."
"You did?" I said, my eyebrows raising in surprise.
Melissa laughed a little. "I did! And so she did. Fuck, I got so wet from that first kiss. It was light at first, just lips on lips, but then she came back and I felt her tongue on my lips. When I opened my mouth she entered and started twirling her tongue around mine. It was fucking awesome!"
"So then what?" I asked, getting a little turned on myself.
"She asked me if I wanted to take things further. When I said I did she gently placed my hand on her breast. It felt so firm yet soft. I started kneading it and felt her nipples get hard so I played with them. She started moaning and encouraging me, putting my hand under her blouse to give me better access."
"Fuck!" I said, now feeling an itchy feeling between my legs.
"Then she took her blouse off and helped me off with mine. She admired my boobs, they're bigger than hers, and actually started licking and sucking on them through my bra. Oh shit did that feel good! I wanted to feel her mouth and tongue on my tits so I undid my bra. She took hers off too and when her tongue hit my nipple I found my chest pushing up and such incredible feelings started hitting my crotch."
Incredible feelings were also hitting mine by this point.
"I started sucking on her tits. I've never had a nipple in my mouth before. It felt so hard and tasted so delicious. There was actually some liquid coming out of her tits as I sucked on them. It tasted so good!"
