He swaps with the woman every time

I had a moment of disorientation, and then... I'm on my back, my roommate naked in front of me, ultra close, my legs spread, on a soft bed in a dimly lit room.

I feel something press into me... and keep going... it feels... long, round, stiff... and for some reason it feels really good? He pulls back a few inches and the intruder slides out... then he slides in more, his hips slamming into my butt, causing my chest to ripple...

I scream as I process what just happened: Somehow, impossibly, I'm now Drew's date, just as they're getting to the 'main event'....
