Once we were alone I led Valerie back up to the bedroom and asked if she was willing to show me just how much she had learned from playing with Jen and watching Lis and Lucy. Valerie blushed and gave me a cute look, then allowed me to remove her robe and she lay on top of me. I opened my legs to let her press her thigh against my pussy and I guided her to my thigh to hump against me as we kissed. I explored her back with my hands and told her she was a really good kisser, then asked her to kiss and lick my neck. Valerie did this and it felt amazing, but it would have taken too long for that alone to make me cum so we went back to kissing properly and then had a little breast play (and discussed how Jen liked it much rougher) while fingering each other. I told Valerie that I thought eating someone was the most intimate thing you could do with them and said I’d like to have a chance to eat her for as long as Mike did. Valerie said she didn’t know if she could cope with that again and that she wanted to be able to do things to me as well so I started teasing her about how she was now begging to eat my pussy but she asked me to stop and said she genuinely wanted to give me pleasure. I’ve known Valerie long enough that I realised she was being serious and apologised for teasing her and explained I had just been trying to keep things light but that I hoped she knew I really did care about her and always had. I decided to take a chance and told her even if she wasn’t really my sister than I honestly did love her and that if us doing things together was more than just ‘experimenting’ to her then I’d be really happy. Valerie quietly said ‘I love you too’ and I asked if she really meant it and how surprised (in a good way) I was. Valerie asked if Jen or Mike would mind I told her that we were polyamorous (which she obviously knew) and that Lis was technically my girlfriend as well. I quickly added that this didn’t mean I loved any of them – or her – any less, it was just that we allowed ourselves to care about people fully and express those feelings however we wanted. I told Valerie I’d understand if she didn’t understand or want to do anything more but Valerie just said that Mike had already tricked her into agreeing to visit again and that she had really meant it when she said she loved me.

I told her that Jen might be a bit jealous (not of me liking Valerie, but of Valerie liking me) and Valerie said she was quite fond of Jen as well. I asked if Mike could be included and she said she doubted Nye would approve of her saying she loved another man (and might not even approve of her actually feeling anything for Jen or me). I kissed her again and said we could just keep things on a purely physical level and I’d make her cum as often as she wanted, but that I’d happily call her my girlfriend if she allowed me to. Valerie looked a little panicked and said she wasn’t ready for anyone else to know, and suggested we even keep it a secret from Nye for the time being so I promised it would remain between us (and Mike and Jen), kissed her again and asked if she wanted to fuck, or spend a morning making love to her girlfriend. Valerie looked up at me with a genuinely cute look (again, I’ve known her long enough to know when she is faking them) and asked if I meant it. We had a long, gentle kiss, said we loved each other and she said ‘make love to me’. I literally felt my pussy shudder and we kissed for a while until I whispered to her that I wanted to slide my tongue into her beautiful pussy and make her cum.

We spent the best part of an hour locked in a 69 (which turns out to definitely be Valerie’s favourite position) and ate each other to three orgasms, with extended kitty kissing sessions between orgasms. When we finally separated and kissed, Valerie said it was one of the most intimate times she’d ever had and I asked her (in a nice way) if she thought she might have been gay or bi all this time. Valerie said it was probably more to do with the fact we’d been such close friends for so long and endured the rigours of our PhDs together so I teased her about how much nicer the time could have been if we could have help give each other ‘relief’ while we were writing up. We joked a bit and I got Valerie to imagine various friends from York who could have helped ‘relieve’ us and Valerie asked if I wanted to do the same things with all of them. I generally work of the principal that honesty is the best course of action and told her that there were many of our friends that I would love to have a chance to sleep with, but that I thought there was a difference between wanting to just fuck someone and wanting to give them pleasure. I told her that it was possible if I ever got to sleep with little Anna, Jo or Rachel that I might well end up feeling more towards them than just lust, but that at the moment, I didn’t love any of them as anything more than close friends – nothing like the way I felt about Mike, Jen, Lis or her (even while being honest, I omitted Sue – honesty sometimes needs limits). I went on to say that I realised this was very different from the way she dated (a serial monogamist) and that I understood if she couldn’t get her head around it but she gave me a hug and said she’d like to try. I told her that I’d probably have to share her with Mike and Jen but added that there were some benefits to this as she’d find out what it was like to have three people playing with her breasts, pussy and ‘other places’ (I was going to say ass, but still thought of Valerie as relatively sweet and innocent).

Valerie blushed and whispered that Mike had already played with her there so I asked what she did and she told me how he and then Jen had licked her there while Mike had eaten her. I told Valerie I was impressed, but that I was jealous and she asked why as it was dirty and I said I wished I’d been able to give her pleasure like that before they had. Valerie admitted (as she had to Mike and Jen) that other people had licked her there before, but not as intensively) and I told her that I couldn’t leave without getting to give my girlfriend the same pleasure. Valerie asked if I was sure and I told her if I was going to date her, then I wanted to be able to give her pleasure in as many ways as was possible. I got Valerie to kneel on all fours on the bed, then to angle her ass up more I got her to put her head and shoulders down on the bed. I started off by stroking up and down her pussy with my fingers, then using my tongue and then moving up to focus more on her ass. Valerie whimpered a little and I asked her if it felt nice – she gave me a quiet yes so I asked if I could carry on and she said I could if I wanted. I occasionally dropped my mouth back to her pussy, but mostly rimmed and speared her ass while stroking her clit until I could hear her breathing deeply and I asked if she wanted me to make her cum. She replied with a ‘yes please’ and I considered asking her to tell me exactly what she wanted, but didn’t want to make her feel embarrassed so just carried on, lapping at her ass and steadily frigging her clit until she came, gripping the covers hard and moaning quietly.

I lapped at her pussy for a few minutes, then helped her roll onto her back and lay over her so we could kiss. Valerie said she couldn’t believe I’d wanted to do that to her and I told her the whole point of caring about someone was wanting them to be able to feel good and that I would do almost anything to give her pleasure. In almost a whisper, Valerie asked if I wanted her to do it to me and I looked at her and said she didn’t need to, I just wanted to do it to her. She said that Jen had said something similar. She caressed my ass as we kissed more and I ground against her thigh, saying we could always fuck once more before going to the airport to see what flight I could get. Valerie pulled me closer to her and whispered ‘Can I at least try?’, I asked what she meant and felt her fingers brush over my ass. I told her again she didn’t have to and she said she wanted to so I said if she was sure then I’d let her do anything to me. I lay on my back and pulled my legs up so my knees were at my shoulders and while spreading my lips, I suggested she start on my pussy. Valerie crouched down and licked me and I told her it felt amazing and she didn’t have to do anything other than that. Valerie licked my pussy a bit more firmly, then I felt her tongue slide down between my ass cheeks and brush back and forth over my ass a few times before returning to my pussy. I let out a little ‘ah’ as she did this and she glanced up at me, then returned her focus to my crotch and licked up and down and around my ass a few more times. I enjoyed what she was doing for a few minutes longer then told her it wasn’t fair as I wanted her as well so let my legs down and pulled her up to kiss me. Valerie giggled and told me it was the first time she’d ever done that to someone so I told her I was honoured to have been the first girl she’d gone down on or had her ass licked by. I asked if she had time for one more orgasm before I left and she giggled, nodded and kissed me.

We 69ed again, with Valerie on top at first, on our sides and me on top at times. This time when I pulled Valerie’s ass down to lap at it, she didn’t flinch at all and even made her way to my ass a couple of times, licking me there much more confidently and even spearing me slightly. Much to my surprise, Valerie didn’t pull away after our first or even second set of orgasms and it was only after we’d cum another three times each (and a little more kitty kissing) that she rolled away and said her pussy couldn’t take any more. Even then, she just moved round and kissed me while we fondled each other’s breasts and I had visions of Nye returning home from work to find us still in bed together and me ‘having’ to stay for another night. Hunger got the better of us though so we went downstairs for food (once again I remained naked and Valerie wore just a robe) but this time there was much more kissing and fondling in the kitchen. We had a quick lunch and Valerie suggested we shower but I told her I wanted to keep her juices on me. She wrinkled her nose up at this but allowed me to lie her on the bed and finger her while rubbing my face, neck, breasts, thighs, arms and ass against her pussy until I was thoroughly coated. Her scent pervaded my nostrils and I asked if I could make her cum one final time and she said she didn’t think she could, but allowed me to talk her into trying so I climbed over her and humped her pussy with my face, licked over her pussy and ass, sucked on her clit and tried to draw as much of her juice out down my throat as I could. It turned out that Valerie could cum again – and I was feeling so horny that I had no trouble cumming. I then went into the bathroom and sat chatting to Valerie while she showered herself off, then threatened to fuck her again when she finished drying off, but realised that she might have actually reached her limit, even for ‘new relationship’ sex.

Valerie insisted on driving me to the airport, saying she’d just take the day off from work, and I was quite surprised that she not only stayed with me until I got a standby flight (I was lucky and it only took 2 hours), but she held my hands across the table and would even give me little kisses. I told her I’d obviously call her and we said we wanted to see each other again soon. I knew Mike and Jen would want her as well but that would mean I’d have to go to Nye so I considered suggesting sending a substitute to Nye (I was fairly sure I could convince Susan, Julia or maybe even Simone to fuck Nye for a weekend) but wasn’t sure how Valerie would take that idea. I assured Valerie I was incredibly glad that she felt the way she did, but that I thought she should take a little time and think about if it was what she wanted and wasn’t just some strange response to the threesomes and that is she wanted to go back to ‘just being friends’ then I would still love her as much as always – although obviously wouldn’t be able to show it in the same way (this got another giggle from her). Valerie said that it felt right and I managed to slide a hand up her thigh and told her we had so much more to learn about each other (I had a few things in particular I was thinking of) and while a long distance relationship was hard, we could Skype lots. Valerie asked me again not to say anything to anyone (including Nye) just yet and I told her that keeping secrets was dangerous but she said she just wasn’t ready yet so I promised (with the caveat of Mike and Jen). I asked if I could tell Lis and Valerie said I could in a little while so I teased Valerie that Lis might well want a piece of her and Valerie asked if I’d mind. I told her that I loved Lis as well so knowing the two of them could ‘get on well’ together would be wonderful and teased Valerie a bit more about how things could have been so different if we’d all been like this in our undergrad days.

Despite her apparently lax attitude to kissing me in public at the airport, we used one of the bathrooms for our proper goodbye where we kissed much more passionately and hands roamed around under skirts. Valerie had panties on so I stroked her through these while her fingers could easily slip into my pussy. I told her she could come and visit anytime she wanted and she said the same. She offered no resistance when my hands slid into her panties and if I’d had time I would have knelt and eaten her, but had to make do with sliding her panties off, rubbing them over her pussy and convincing her to let me keep them so I had her scent. Valerie said this wasn’t fair as it meant she didn’t have anything to wear on the way home and as she wouldn’t have anything with my scent on it. I told her about the panties Nye and I had used that were soaked in both my juices and his cum and how the plan was to get her to wear them, but that wasn’t what Valerie wanted and we ended up looking out my emergency panties (I may never wear them, I but always have a pair ‘just in case’) and wiping them over my pussy. I pushed them up inside me, then did the same to Valerie with her own panties and we took them out of each other to use during our Skype calls. I then had to run to my gate to catch my flight so had calmed down significantly by the time I got onto the plane, but sat with my legs partially spread, feeling the cool air on my still wet pussy and dreamt of Valerie.

Mike came to get me from the airport, bringing MJ with him to allow Jen more alone time with Rachel. He instantly commented on my scent (of which he approved) and I wondered what the people I’d been next to on the plane had thought and whether the pheromones coating me had aroused them at all. At the car, I allowed him to lick my thighs and he said he could faintly taste Valerie and asked how things had gone. He could tell that I was very happy and kept digging for information but I had decided to wait until we were home before the big reveal and it was only when MJ was asleep and Mike, Jen and I were in bed that I gave them all the details, including how Valerie was now my girlfriend and confirming that she would be visiting again. A Jen was (as predicted) a little jealous about this, but more than that she couldn’t believe Valerie would have had such a change of character. I told Jen it must have been her wonderful teachings that made Valerie realise she was bi (or maybe even gay) and Jen took the compliment but was still confused (which, to be honest was no different from how I felt about the situation). When we called Valerie later on that night, I got one final surprise as she was crouching on the bed with Nye, naked – apart from what used to be a cute pair of panties but was visibly stained with my pussy juices and Nye’s cum. Jen and I sat and masturbated for Nye and Valerie as Nye rubbed Valerie through the panties and she stroked his cock. As Valerie got closer to cumming, the panties were pulled down enough to let us watch Nye finger her and when he came, he squirted his cum over her pussy and rubbed it in to her. I then got Valerie to spread her legs and told them how I wished I was there to lick all of Nye’s cum from her pussy and when Nye went to the bathroom to clean off, I told Valerie I’d keep licking until she came another six times for me. Before Nye came back I gave Jen a little kiss, blew a kiss to Valerie and told her I loved her. She same the same in return and Jen said she was very happy for us (which Valerie said she found odd, but we couldn’t continue that conversation as Nye came back and we had to pretend the ‘odd’ comment was about Jen enjoying Nye watching her cum).
