2 or 3 rooms down from the lab was the toilet, so I led him past the lab and in to one of the toilet stalls. I pushed him up against the stall door an...d gave him a smile. When he smiled back I knew he wanted a repeat of the other night so I pulled him in and we stood there making out for a good 5 minutes when I noticed his hard cock pressing against me. I pulled away, laughed a little, and said "Wow, you really like this, don't you?" I've never actually done this with a guy before but... yeah, I. I shuddered and moaned, thrusting my hips faster, in rhythm to his rolling my nipple in his mouth. I felt his hands move to my back to cup my buttocks and pull me closer. His penis felt as though it was getting even longer and thicker and harder, and I knew he was close to coming. His lips shifted from my left nipple, licked across my breasts, and fastened on my right. I felt my orgasm begin to approach as he began to buck his hips under me. It was like standing at the mouth of a tunnel,. Grabbing it with my left hand I begin to pump. I must have been to loud. She heard me. She vibration stops. She sits up. "What's that?" I hear her whisper."Sorry, it me." I reply. now embarrassed."What were you.." Same as you." I cut her off."Oh." she replied sheepishly."Do you....do you want to finish?" I ask."..ok..but you have to come here so I can see."I throw off my blanket and tip toe over to the bed. I sit at the foot of her bed. "Remove your blanket to so I can see." I say. She. Now I was only in underwear, and she was wearing only bra and panty. I hugged and kissed her again. I got hold of buckle of her bra on back, and then I unhooked her bra as well. Her big boobs were open in front of me, and I started sucking them like a baby. Then I asked her if she has any ice cream or jelly at her home. She pointed to a refrigerator. I immediately went to kitchen, and found strawberry ice cream in fridge. I took it out, grabbed a spoon from kitchen, and headed to bedroom.She.
