Why not...

I knew that it was not polite to check her phone behind her back but I was curious. I had seen her before, typing her password to unlock her phone few times, so i knew i could open her phone. When I browsed through her phone I didn't find anything interesting. I then checked her chats with Sam and all of them were normal so I was relieved but when I started looking in the gallery and I came across few videos. When I played the video it was Amber and Sam in action. I was shocked to see the size of the Sam's cock he was almost 8 inches and even Amber was looking like she was really enjoying it. I have only seen woman in porn enjoy this much. It just meant that Sam was that good in bed and it made me nervous as Lisa must be expecting the same from me.

But still looking at those videos had made me hard. That's when I heard the shower turning off and I kept Lisa's phone on its place. When Lisa came out she noticed my boner and said, " Baby are you ready for round two. Last time you lasted 2 mins. Hope this time you will last longer". Saying that she got on her knees and kissed your cock again and said, " Baby you know you can't last much longer so why don't we stop having sex till you are able to last 10 mins when i give you a blowjob. Like that even I would be able to enjoy when we both lose our virginity". Listening to her suggestions I think it would be a great chance to improve myself and maybe I'll be like Sam in few days. So i nod my head saying yes... And lisa begins to lick my cock while looking at my reaction. I close my eyes and try to control myself so I will be able to last longer than 10 mins.
