It was new year and we were drinking, up north big group of 30 ppl or so. One of my friends ex g/f was there and she was really digging into me and the more drunk I got the more the idea and flirting was enticing me. My other friends saw my friend watching her and getting jealous but they saw I was horny so one of my friends told me to go meet them in the sauna and we will hot box it, I get in there an a minute later he comes in with some other girl making out half naked. At first i didn't know what to do but then she turns around to me and started taking my pants off kissing me while my other friend is pulling her skirt down. Next thing I know she is swallowing my cock down her throat while my friend starts going at her from behind. We switched and I started banging her from behind but he lost it and ended up running out of the sauna. She looked at me and we said fugg it and kept going till we both came so nicely.
