Spontaneous wild night [cuckold’s perspective]

Last night we had a random meet! She found a guy on tinder who was an hour away from us he told her to come over straight away I was tired and it was late at night but she insisted had a shower and got dolled up.. I drove for an hour and we arrived at his place .. he was super tall 6-5’ and big and she’s only 5-2’ .. he gave us drinks and we chatted and he started making out with her on the sofa and she started grinding him on top of him and he kissed her neck and they kept making out in front of me non stop for like 15-20 mins and dry humping .. he then picked her up and put her on his shoulder and told me to stay downstairs as he took her upstairs to the bedroom.. I could hear her moans so loud and after a while I slowly sneaked up without trying to make a noise but the floor creaked so I stopped in the middle luckily he didnt hear .. I waited for while and stepped further and now I could see through the door while still on the stairs but didn’t see them I stayed there listening and after a while I saw him move her on the bed with her head hanging side of bed and then he came over and started fucking her throat as he took his cock out to let her breathe her eyes noticed my head popping through the stairs and he buried his ass in her face and she started licking his ass he then carried on fucking her throat and then picked her up and moved her out of my view again and I think started fucking her .. I moved up a little more now and got on the floor and sneaked by the door and peaked through his back was against me and he was fucking her doggy style pulling her hair they couldn’t see me now so I moved further and got a good full view .. I was leaking cum now and started stroking myself .. after a while she started cuming and started to collapse on the bed and he paced up even harder and she kept squirming and I came too and tugged my boxers to ensure my cum doesn’t drop on floor.. he then slowed down and I moved back as he was changing position .. he picked her up and started fucking her in the air with her back against the wall.. I couldn’t risk being seen so I moved back and started to move back downstairs slowly as the floors were creaky .. but floors creaked loud and he heard and said whose there I meekly moved and showed in front of the door with my head hanging in shame as he had her pinned against the wall.. he then said to me man I told you stay downstairs in an angry voice and then told me to come here now he then told me to help him hold her from behind as I positioned behind her and held her ass cheeks and weight as he fucked her and I was being pushed into the wall with each thrust .. he then picked her up himself and told me to kneel and lick her ass .. as he fucked some more his balls slapped my face .. he then told me to lay on the bed and moved her in 69 above me and started fucking her as I licked her clit she started cuming again and started squirting on my face and then he started to cum too and pulled out and came on her ass .. she then collapsed on my face and started kissing him .. as we all lay collapsed there for a while .. she then got up and got cleaned up and we went downstairs and I drove back home around 2am and we passed out.. next morning he texted her how much he enjoyed her and he would coming to visit us very soon..
