My perverted roommate LINA MILA wants sperm

Phew, what was that? I still can't believe it!! The new roommate Felix has only recently moved into the shared flat. Well, actually he is the fiancé of my good friend Nadja. Who also lives in the shared flat. That day I thought I was alone. So I made myself comfortable on the sofa and wanted to get it nice. I was so horny!! Full of ecstasy and just before my orgasm, Felix suddenly bursts in. Phew, that was embarrassing. And then he made me a very immoral offer. Was he serious? He just unpacked his hard cock and then... well... hopefully Nadja won't find out about it....
