Rav's first time

We had been chatting to Rav a little on Reddit and had formed a connection, he is 20 and in his own words quite nerdy and very keen to lose his virginity before he turns 21.
He was interested in joining us but also a bit tentative and nervous so I suggested we would meet up at a hotel for a drink and there would be no pressure to do anything at any stage.
We had a room booked upstairs and had planned to stay either way. During the conversation it was evident he was quite nervous and to help break the ice I asked what sort of porn he likes to watch. He said lately, especially since we had been chatting it had been mostly watching older couple porn so it seemed only fitting to suggest he could come upstairs and just watch us if that's what he wanted and no pressure to do anything else and he could get his 'business' sorted another time, he has a few months before he turns 21. He thought that was a great idea, later admitting that was what he was hoping for.
Kat has always been a bit of an exhibitionist and lately I have started to see the attraction and while we had done a few threesomes and had sex in front of the other person [and one time another couple] it had always been me watching first so it was a bit of a new situation for us and we were both turned on by it.
We went upstairs and settled Rav into a chair by the bed and made sure he knew he could do anything he wanted while he watched. Kat and I got on the bed and started kissing and fondling, slowly undressing each other until I was naked and Kat was just in bra and panties. We were both on the same page that if Rav was only going to watch he was going to get a good show.
Kat sat on the bed facing Rav and I was behind her kissing her neck and holding her boobs, then undid her bra and removed it, exposing her rock hard nipples. I leaned around and sucked on one nipple while Kat made some eye contact with Rav and shared a smile.
Kat knelt on the floor between the bed and Rav and pulled me over to start giving me some head and made quite a show of it. She would make eye contact with me then look around and give Rav a sexy smile glance at his crotch and lick her lips. Rav was still fully clothed at this point but there was an obvious bulge in his pants.
Soon I asked Kat to sit and lean back on the bed and slipped her panties off. I went down on her and in a few minutes she was having her first orgasm of the night. As she got her beath back Kat lifted her legs holding her knees and said please fuck me now, I want you inside me. Rav moved to get a close up view as I spread her lips and slowly pressed the head of my cock into her.
We fucked like this for a few minutes then Kat wanted some doggy action and went on to all fours, facing her ass directly at Rav the after a few minutes that way wanted to turn around so she was facing Rav.
While I slowly pumped her from behind she said to Rav that the bulge in his pants looked painful and he should let it out for her to see.
He opened his pants and pulled them down a little so she could see his erection & it was everything Kat likes about a cock, hard with a shiny helmet moist with a lot of precum, not huge but a reasonable size. She told him how beautiful his cock was and asked if she could see more of him. As he took off his shirt to reveal his body I knew Kat liked what she saw, she started pressing back on me and told him how hot he was and then saying how much she liked having a cock inside her and she started cumming while looking at him and telling him he was a good looking guy.
After Kat came it was my turn and she rolled onto her back and I fucked her missionary for a moment before I came deep in her.
I rolled off and sat next to Kat and as she gently touched her clit I opened her labia a little wider and Rav and I watched as my cum ran out of her. He seemed surprised that I came inside her and Kat seemed to sense something and told him there was no chance at all of her getting pregnant and that she loved having cum inside her.
Rav massaged his balls as he looked at us and he said he had enjoyed watching, Kat said to him that he obviously needed to cum before he exploded and he agreed.
Kat asked if she could help him cum and he nodded so she knelt in front of him and cupping his balls with one hand stroked him gently with the other. She knew he was ready to cum and started along slow lick from his ball sack up his shaft to the top and by the time she got to the tip his first squirt of cum hit her cheek, she quickly pointed his cock at her boobs and continued the stroking as he shot string after string onto her, he was groaning and squirming and Kat was telling him how good he was.
Eventually Kat sat back and told him he had the biggest load she had ever seen and thanked him for it. He sat there legs apart catching his breath, his cock which had lowered but not gone completely limp started rising to attention again as he looked at Kat's cum covered boobs.
I said I don't think he is done and Kat said it was ok we have plenty of time if you want to stay for a while and he agreed this would be good.
Kat asked if he would like to touch her boobs now that he had cum all over them and he leaned forward and started playing with them, rubbing his come all over them. Kat said she needed a shower and started getting up, Rav asked if he could wash her and she said that sounded nice.
At this stage I was rock hard again but knew I would have to wait.
Kat and Rav got into a steamy shower and soaped each other up, Rav spent a lot of time washing Kats boobs and Kat put her arms around him and gave him a hug, pressing her boobs onto his chest. She moved behind him and pressing her boobs on him from behind reached around and started stroking his cock, I thought he might black out he seemed to enjoy it so much but she stopped before he came.
Kat turned him around and knelt in front of him, he gasped as she slid her mouth over his cock but again when she sensed he was close to cumming she stopped. He looked like he was in pain and I smiled knowing exactly what she was up to.
She said the shower was over and I got in to freshen up while Kat led Rav back to the bedroom.
When I got back to the bedroom Kat and Rav were sitting on the bed kissing. Kat looked at my erection and said I looked like I was ready to go again and I said it looked like Rav was ready as well. I said mate you should try it while you have the chance it feels so good.
Kat looked at him and said do you want to try it?
He had just the slightest hesitation and Kat jumped in and said I would really like you to and he said yes.
She kissed him on the lips and said we will have so much fun.
Kat lay back and said come here and pulled him on top of her, he kissed he mouth then her boobs and she said I'm so wet, I want you inside me and as he leaned up she reached down to divide her labia for him to see where he had to go.
The sight of him holding his erection and pressing the tip between Kat's labia made my balls ache.
Kat encouraged him and seconds later he was pounding furiously away like a pro. Seeing his slim brown ass pumping between Kat's legs and their combined moans made me feel like my balls would explode and I couldn't help but stroke some.
I think Kat sensed Rav was going to cum and said to him tell me when you are going to cum so I can cum with you and that sent him over the edge he immediately said I'm cumming, and just like that they shared a pretty explosive orgasm.
Rav lay on top of her and said it felt so good and it was obvious he didn't want to pull out but wasn't sure what to do next so Kat grabbed him and said just stay there it feels good for me too.
She moved her hands over his back and butt and told him he was very good at this already and it felt so good for her too. She said thank you for that and kissed him a little.
I saw his butt clench a few times and Kat pulled back from the kiss and said Really? He just nodded and slowly built up the pace. He maintained eye contact with Kat which I know she loves and soon was pounding madly again. Very soon Kat was showing signs of cumming again and started breathlessly and probably needlessly saying don't stop until she had a massive orgasm. It threw off Rav's rhythm and he stopped and said he really anted to cum again but wasn't sure if he could. Kat said it was fine he was doing a great job and there was no rush.
I suggested they try something different , maybe some doggy and they both agreed that sounded good.
Kat got onto all fours on the side of the bed and Rav moved behind her, checking out her bits from behind.
I asked if it was ok to watch him go inside her and he leaned back a little to give me a view as he guided his cock into Kat and he seemed to enjoy the same view so he continued to slide himself in and out slowly as he watched his own cock. Kat was almost gagging and saying how good it felt as Rav picked up the pace and kept watching himself as he ejaculated into Kat.
He pulled out and stepped back, some of his cum was clearly visible in Kat's vagina and I couldn't help it at that point and said I really need to cum. Kat just laughed and said well I'm in position.
I pushed Rav's cum back into Kat with the tip of my cock and slid inside her and came a minute or two later.
Kat stayed where she was for a bit so Rav and I could watch our loads dripping out.
Ra asked me if it bothered me fucking Kat with his cum inside her and I said it made it feel even better and Kat sat up and said it made her feel very naughty and horny having both our cum in her.
It seemed like the end of the session and Rav agreed he would like to visit again.
Kat said hey before you go lay down for a second and she leaned over and surprised him when she started giving him head. He certainly did not object and when he was rock hard Kat climbed on top of him and rubbing her labia on his cock and her dangling her boobs in his face and said do you want to be inside me?
He nodded and as Kat leaned forward to find his cock I took the liberty of grabbing hold of it and guiding it into Kat, I don't think he realised it was me at the time.
Kat rode him for quite a while and they both had a little orgasm.
Kat thanked him, got up and said she needed another shower. Again Rav followed her and she washed him before giving him a kiss and telling him that she really enjoyed what he did to her and asked if he would come back again to which he responded very positively.
