“Doing some research on the Internet, Rick?” I jokingly asked my boyfriend. I had walked into the computer room in my boyfriend’s apartment and caught him looking at hard-core porn.
He tried to minimize the picture when he heard me, but it was too late. I had already seen the very graphic pictures on the monitor. He looked embarrassed that I had caught him viewing the porn. I knew that if I had come into the room five minutes later, he would have been masturbating.
“Uh, hey, Miranda. What’s up?”
“Nothing. I just came to check up on you. You have been at the computer for hours.”
“Oh, I finished my work, and, well, you know. I was looking at some porn. No big deal.”
“Rick, believe me. I am probably more open to porn than any woman you have ever dated before. I am just curious as to what was on the screen. It looked really kinky, but I only saw it for a split second before you turned it off. What was it?”
Rick’s face turned even redder. “Oh, nothing. I forgot what site I was on.” He stammered.
“Bullshit! Here, let me see.” I seized control of the mouse and hit the history button on the browser. “Hmm, interesting URL. Let me click the link. HOLY SHIT!”
I saw one of the most graphic pictures I have ever seen in porn. In the picture, there were two very attractive ladies. You could only see their heads. The first lady was a blonde with her head tilted back. The other lady was a brunette with her head directly above the blonde lady. They had bright red lipstick on, and their mouths were both wide open.
From the picture, it looked like the two women were about to make out. This all sounds pretty soft-core so far, right? Well, here is the shocker. The brunette on top had semen dripping out of her mouth directly over the blonde woman’s mouth!
“Wow, Rick! This is kinky!”
He didn’t respond to my comments.
“Rick, what is this? I’ve never seen a picture like that before. Is there a video of this anywhere? I want to see what happens.”
“Uh, yes, there is a video. Hit the back button, Miranda.”
I was relieved that Rick was becoming comfortable enough to talk about the porn site finally. I hit the back button and saw the same picture in a gallery, along with a few more similar pictures. I clicked the picture of the brunette and the blonde, and a few seconds later my Windows Media Player started to play a video. My eyes widened when I saw the hot white come drip out of the brunette’s mouth and into the blonde’s mouth! When the video was over, I clicked all of the other ones and watched more short previews of women sharing sperm with each other.
There were also other videos of the women having sex with a well-built guy, and then giving him a blowjob. After the blowjob scenes, the woman who gave the blowjob kissed the other woman in the scene and transferred the come into her mouth. I had never seen such a unique site with such a great combination of hot lesbian sex and hot straight sex as well; usually, porn sites focus on one or the other.
I stared in awe as I watched the videos. This was something kinky that I had never seen or even imagined. I knew that guys always wanted their girls to swallow the come after giving them a blow-job, but I imagined that most guys would be happy to see this result. Now there were three choices for the girls to make: Spit, swallow, or sperm swap with another woman!
“Holy shit, Rick, this is cool!” I yelled. I know that many women get upset when they catch their men surfing for porn on the Internet, but I totally accepted it. I actually encouraged it, since I am the web-mistress for a sex blog myself, and Rick often finds interesting things on the Internet for me to write about on my posts.
“Yeah, you like? It isn’t too kinky for you, Miranda?”
“Too kinky for me? That would be pretty kinky, Rick! Let me watch some more.” I took control of the keyboard and clicked on some more videos. I got wet as I watched. Some of the videos were good hard-core porn. I love watching people fucking; I usually imagine that the guy is fucking me instead of the porn star on the screen. The sex scenes were above average for a porn site, and the blow-job scenes were well done. I could see how Rick would get really turned on, imagining that he was the guy on the screen getting the blow-job.
After each blow-job scene, the lady would keep the come inside her mouth, and then stand over the other lady and let the come drip into her mouth. I wondered what it would be like to do that. First, I imagined what it would be like to be on the receiving end of that activity.
I wondered if the come would still be hot after being in the first woman’s mouth for a minute. When they kissed, I imagined the come getting mixed with their saliva. I pictured the come traveling back and forth between their mouths as their tongues intertwined. I knew that this was something I would have to experience for myself.
A few days went by, and I couldn’t get the image out of my mind of the two women swapping sperm. Rick and I have had threesomes before, but I didn’t know if he would really want to do this. I had made up quite a fantasy about this activity, but it involved Rick, myself, my friend Donna, and her boyfriend, Sam. Rick and I had never been involved in group sex with four people at a time instead of three.
“Rick, remember that site you showed me the other night on the Internet?” I asked him after a nice dinner of homemade buttered scallops and linguine.
“Oh, the one with two women sharing come?” he asked, as if there was some other site I might have been asking about.
“Yeah, that one. It got me really hot. Hotter than most of the porn you find on the Internet.”
“Oh, cool, Miranda. I’m glad you liked it. I have it bookmarked if you want to see it again. They have some new videos,” he replied as he started to clear the table and bring the dishes to the sink.
“Well, I do want to see it again. But that is not why I brought the subject up, Rick. I, um, oh, I don’t know why I am embarrassed. We share so many fantasies together. I want to do that with you for real!”
I turned red, bracing myself for a possible negative response.
“You do? For real? Wow!”
“It was just an idea, Rick. I don’t have any idea why, but that site was so different. It really turned me on! I guess when I see something sexual that I know nothing about, I get really curious. Like the time you showed me that site with the elaborate vibrators that got women off.”
“Oh, the Sybian machines? Or as I like to call them, the ‘fucking machines?’”
“That was cool too! But really, I want to try this.”
“I’m up for it, Miranda! We just need a third partner. How about your friend, Suzanne?”
He was referring to a good friend of mine who had once had a threesome with the two of us. Rick had had a blast, but I didn’t enjoy it as much as some other threesomes because she wouldn’t explore bisexuality at all. Rick got most of the attention since he had two women catering to him, but I only had Rick to cater to me, because Suzanne wouldn’t even make out with me, much less kiss my pussy.
“I was thinking about asking my friend, Donna. I know she had some lesbian experiences in college, and I am pretty sure she is just as sexually adventurous as we are, Rick.”
I knew that this selection would not disappoint my boyfriend. Donna is very petite, with short, straight, blond hair and a wonderfully cute figure. Her breasts are on the smallish side, but they are the most perfectly proportioned things I have ever seen, and although her legs are short, they are smooth and tan. She also wears revealing tank tops and tight shorts all the time to add to her sex appeal. She is very perky and has a wonderful, optimistic personality.
“Wow, Mirada. If you can convince Donna, it would be fine with me!” Rick laughed. “But she has a boyfriend. What’s his name, Sam?”
“Yes, we would have to involve him too.”
“Why would we have to involve Sam?” Rick asked.
“Because I can’t just expect my friend to tell her boyfriend that she is coming over to our place to have sex without him! That wouldn’t be fair to Sam, Rick. There’s no reason why he can’t be a part of this as well. And besides, to have a ‘sperm-swap,’ you need a lot of come! After you come, it takes a while to recover, and I want to be on both the receiving end and the giving end of this activity.”
“Well, you do make some good points. Make the arrangements and count me in, Miranda!”
“I will do just that,” I said with a wicked gleam in my eyes.
During the next week, I made the arrangements with Donna. She easily convinced her boyfriend, Sam, to get involved, and he even offered his house for the night’s activities. We arranged to come over to her house the following Saturday night at 9:00 after dinner. Donna called me the day before to tell me how excited she was.
“Well, Miranda, I have to give you credit, you discovered something that neither Sam nor I have ever heard of! Where the fuck do you find this kinky stuff?”
“My boyfriend deserves the credit, Donna. He spends hours surfing for porn at night. I can’t get mad at him, though, since I do it myself. I spent an hour looking at the sperm swapping videos after Rick showed them to me!”
“Well, I’ll see you at 9:00 on Saturday, Miranda! Tell Rick I said hello.”
The following Saturday, Rick and I had a nice seafood dinner at a restaurant near Donna’s house. I rang the doorbell, and Donna answered the door. She was wearing a pair of tight blue jeans and a tight black tank top. We said hello to her boyfriend, Sam, and sat down to have some cocktails. I sipped on a Jack and Coke and looked at Sam. It felt awkward to sit next to him, knowing that he would be my sexual partner very shortly.
After an hour of small talk, Donna broke the ice by simply stripping her clothes off without saying a word. Rick, Sam, and I all stared at her chest as she peeled off her tank top. She wasn’t wearing a bra. I’m sure all three of us were dying to put her cute, firm tits into our mouths. I put my hand in Sam’s lap to feel his erection. We all watched in awe as she dropped her pants to the floor and kicked them aside. She had no panties on. She let us watch her nude body as she walked over to the couch where the three of us were sitting.
She sat down on my boyfriend’s lap. Sam and I were at the other end of the long, red sofa. It was very erotic to watch my friend sit on my boyfriend’s lap. She was facing him, and he started to fondle her tits as Sam and I watched. I wondered if it turned Sam on to watch his girlfriend get fondled by my boyfriend.
I took off Sam’s shirt and kissed his lips as he fondled my tits through my white short-sleeve blouse. This felt really good, so I removed my blouse and black bra to give him full access to my tits. I looked over and saw Donna remove my boyfriend, Rick’s, clothing. I enjoyed Sam’s touches on my breasts and back as I watched my friend strip my boyfriend. When she had him completely naked, she sat on his lap again. I knew that she would soon be sucking his cock.
Although none of us had discussed the sperm-swapping yet, it was on my mind. I wanted Donna to give Rick a blowjob first, and then I would let her share his come with me. Then I planned to watch Donna go down on my boyfriend and swap his sperm with me. I unzipped Sam’s pants and pulled them to the floor, exposing his blue boxers.
I could tell he was extremely erect. I didn’t want to give him his blowjob too soon; I wanted to keep the two sperm exchanges separate, and to do this, we had to make our boyfriend’s ejaculate separately. I explained this scenario to Sam, who thought this made good sense, even though he would have to wait longer to come. I held his hand, and we both watched Donna and Rick get it on.
