This time inside my pants. You rub my clit in a circular motion and I moan your name. You begin sucking and biting my nipples while fingering my wet p...ssy. I lay there in ecstasy. While moving from my breasts to my neck and I whisper in your ear, "I'm so wet, I need you."

The hotel was mostly booked, but they did have one room still available.They walked over to the elevator. Stella’s shirt still open.

The lab assistance came and gave us the key of lab and asks us to lock it properly before we left the lab. Now we were alone in that huge lab. This is when I started to think.
