Lynn said wow that would be great if you don't mind, as gave me somescotch tape scissors and a roll of really cute looking pink birthdaywrapping paper... that had what looked like little baby golls on it, whichshe had also bought while picking up the gift.I said no problem and went about doing my thing making the gift reallynice looking. When I was done wrapping the gift, Lynn handed me a stick-onpink bow, so I put the cute pink bow on the gift and we were all set.It was still early so we decide. My cock was already hard and ready. I wrapped my Sister’s knickers around my hand and started to jerk.It didn’t take me long to cum.I was an expert at this, so I was ready and I caught all my seed in my free hand, making sure none of it got on her panties or on the floor.Then my Sister opened the door and busted me. I froze in shock. She stood in the doorway, her face unreadable, just looking at me. I could feel my face turn a bright shade of red. My heart was pounding. I wanted to run, but I. A few days followed. My next move was planned a bit better. I knew Charlie would be going pass my room at some stage during the evening. So I got prepared. I had the bedroom door wide open. I dressed down to a tiny pair of red g-strings and a push-up bra. I sat down reading a book waiting to hear his footsteps going up the stairs. A while later I heard him coming up, I threw the booked down, grabbed a bottle of moisturiser and started rubbing my legs, putting one leg on the chair, positioning. His robe parted revealing a very large black cock, “come over here sit next to me baby we can talk”. She laid down beside him, instantly he started kissing her their tongues danced in her mouth. She felt his hands rubbing her tits, bra off he started rolling her nipples with his fingers. His other hand was gently messaging her clit which was sticking up she was wet. She grabbed his hard cock leaned forward as her tongue licked the head, then the entire shaft to the base where she continued.
