My girlfriends cunt is lubed with another guy's cum

I've been dating my girlfriend for a couple of years now. We are in our third year of college. I knew she had slept around a lot before we started dating. It made me jealous but also turned me on. Sometimes when we fuck I make her tell me about fucking another guy. I make her tell me about their cocks and about a specific fuck she had with them. As soon as she starts telling me about them I can't help but cum.

She had invited me over this afternoon because she 'wanted to talk'. I thought I was in trouble but she sat me down on the bed and said 'it is about James'. 'Last night he came over here so we could study together. When he left, he tried to kiss me and I kissed him back'. I was mad angry at first 'I'm sorry, I'll do any thing you want'. 'What else did you do?' I said angrily. 'Nothing'. 'Tell me or else...'. 'He felt my tits a bit and I rubbed his cock through his pants'. 'How big was he?'. 'Pretty big'. 'Bigger than me'. She paused looking shy. 'Is he bigger than me?'.

'Yes' she said. 'Do you want to fuck him?' I asked. 'No' she said. 'I don't believe you'. 'I like him'. 'Do you want to fuck him?'. 'Yes'. 'Right, I'll let you do it but only under my conditions. First, I want you do it in here. I want to hide in the cupboard and watch. I want to fuck you as soon as he leaves. I don't want him to use a condom and I don't want you to wash beforehand.

I made her invite him over straight away. He was busy but said he could be there within an hour. I made her put on her shortest skirt and fishnet stockings. I went down on her so I had her juice all over my face and made her go take a piss and not wipe. When James arrived I quickly got in the cupboard and kneeled down to look through the keyboard. She quickly started to kiss him passionately.

By how quickly they got down to kissing each others necks and fondling each others bodies I could tell Sarah was lying about how far they went last night. I was fucking hard but only dared stroke myself gently in case I was heard. James bent her over the sofa and lifted her skirt up. He moved her knickers to one side and buried his face in her wet dirty pussy. He was licking her asshole and clit and all over butt. He pulled his cock out and put his cock straight in in one go. Sarah squealed in pain and delight. I could see his cock and it was indeed thicker and longer than mine. They fucked hard and wild for a bout ten minutes before he came inside her.

They lay kissing and I imagined all his cum being held in by his cock. He slowly pulled out and Sarah took him to the bathroom and washed him. I told her to treat him ike a high class prostitute would. She gave him a long deep tongue kiss and said 'Now, get out of here, Tom is coming over. I'm going to fuck him, but don't worry I'm going to be thinking about what we just did. And I want to see you again soon'. He looked shocked but did as she said and dressed quickly and left. I could tell that this was going just the way Sarah wanted it to.

I came out of the cupboard totally naked as I'd gone in and rock hard. Sarah sat of the sofa with her legs akimbo and his cum dribbling out of her pussy and over her asshole. I got down on all fours and licked her like a mad man. She held my face against her moaned in pleasure. I stood up and she said 'get me my vibrator' I went to the draw and got it for her. 'Now wash yourself' she said. I washed my cock and came over to her. 'your cock is smaller isn't it'. I nodded and said 'Can I fuck you'. 'ok' she said. She was already pleasing herself with the vibrator. I started to fuck her 'Did you like it with James?' I said.

'Yes' she moaned. She shut her eyes and said 'Oh, James I love your big cock, it's so much bigger than Tom's'. She knew my fantasy is to fuck her with another guy and she was driving me wild. I was getting close to cumming and she pushed me off her and said 'you may not cum until I have'. I calmed down and then entered her again. she built her self to a huge climax and I could feel her wet cunt tighten around me.

I looked down to see James' cum all over my shaft. She looked me in the eye and said 'you may cum now'. I fucked her as hard as I could and then put load after load inside her. she stuck her tongue in my mouth. We lay for a second. She made me clean her with my tongue and then wash her in the shower. 'Next time, I'll let you fuck me together if James is up for it' she said with a smile.
