They leave for the bedroom

One after the other, they leave the living room without anyone but you noticing. At first, you think she left to clean a bit, but after a while, you think it's strange they both haven't come back. You leave too, before heading upstairs when you start hearing some noise coming from your bedroom. The door isn't fully closed so you decide to peek in.

You don't know how to react. You can see your body fucking your girlfriend in your bed. You want to barge in and stop them, but your body doesn't, you even start felly a wetness between your legs and your body getting hotter. You can't stop looking and your hand slides between your legs without you even noticing. You start trying to contain your moans as you watch Jessica getting fucked by her best friend. That's when she sees you and smiles at you. You can't help but cum with no way to hold you moans, but are saved by Jessica who came at the same time. You decide to run downstairs before anyone noticed you left.
