Slutty Gf Wanted Threesomes

My gf can be very slutty and likes to show off. After a house party a friend stayed at ours as he lived too far to travel. We had all been drinking and had a few lines until we were the last 3 there. Knowing we wouldn’t be able to sleep we carried on drinking which led to a few more lines. She was wearing a very revealing dress showing a lot of cleavage bouncing every time she moved. She had already been dared to flash them earlier in the night. She was sat inbetween us the sofa as she let me do a line off her tits. She let my play with them and didn’t try to hide her nipples as I squeezed them. She the asked if we both wanted another line off her. She led bad as we both did it I slide my hand up her leg slowly and she spread our legs over up making her dress slide up over her hips. I didn’t know bye she didn’t have any underwear on. She first pulled me in for a kiss before doing the same to him. She was dripping wet as we both fingered her. He took his cock out first before she reached down for mine. After a while she stood up and slid her dress of and kneeled on the floor, jerked us both off before she started to swap sucking us. After a while she bent over so he can fuck her as she sucks me. He pounded her till he came inside her then she rode me till we cum together.
