myself and girl friend both get fucked by same guy

im a bi sub guy who loves wearing high heels,stockings,short skirts and make up while being fucked up the ass and last monday i met a guy from plymouth who wanted to tie me up and fuck me and make me promise that he would do whatever he wanted so how could i refuse??When he came down i was wearing pink knee high pvc boots,black fishnet stockings,short pink skirt and make up.When i let him in he was holding a bag and in it was hand cuffs and rope.we went into the bedroom and he stripped naked and made me suck his nice long cock.When it was nice and hard he tied me to the bed and rammed his cock in me and fucked me good and hard and i loved it.after a while he shot his load inside me and went and sat in the chair and said”i haveant finished with you yet” but as he was catching his breath my gf came back eirly from work.Well there i was wearing heels,stockings.skirt ect and my ass hole wide open and leaking cum and the guy naked in the chair.She just stood there looking at us both trying to take it all in.Shes 22 and was wearing a light white blouse,short black skirt,black hold up stockings and black high heels.(its her work uniform).when she started shouting at us both the guy just got up grabbed her around the waist with her arms pinned beside her and started to kiss her.he then threw her on the bed beside me and told her to stay there.He untied me and told me to sit in the chair and reminded me i promised to do what he said.He then cuffed my girl friends hands to the bed and said to her “If you dont start to relax within a few mins i will get dressed and leave and tell your boyfriend to take off the cuffs when i have gone”.He started to kiss her again and lined his cock up with her pussy and started to run his hand over her legs.Within a few mins she started to relax and enjoy being kissed and touched.With that he started to push her skirt up towards her waist and she lifted herself up to help him.He then pulled away from kissing her and was on his knees and able to use both hands to push her black skirt right up around her waist.He could see the top of her stockings and her thong which he slid down her legs and on to the floor.As he looked into her eyes he opened her legs and got between them and started kissing her again and then moved his hand down to put his cock inside her and said “I have just fucked your slut boy friend now im going to fuck you”.With that he started fucking her fast and hard and i sat in the chair with my cock in my hand wanking myself watching someone fuck my girlfriend.I watched his hard cock go in and out of her sexy wet cunt and hearing her moam and him breath heavy as they fucked right in front of me.After a while she cum screaming with pleasure and makeing a wet patch under her fucked cunt.Just after that he pushed really hard inside her and gave my girlfriend his spunk and they both just lay there still for a min or two with her sexy legs wide open and his cock still inside her.When he got off he made me clean his cock with my mouth which i enjoyed very much tasting my girlfriends cum and his spunk in my mouth.When his cock was clean he got dressed threw me the keys to the cuffs and said “release her when im gone” and with that he went.I released my gf and she said “I enjoyed that and want you to stay in what your wearing for the rest of the day”
