I and my sister were watching some stuff on Facebook on my mobile. She was holding my hand very tightly as it was cold. I slowly moved my blanket so t...hat my dick and balls came out, which were visible to her.My dick size is 7 inches. She didn’t see it. I moved my mobile a little bit so that she can see my erected dick. She saw finally and she was shocked. She was looking it continuously, she wanted to touch it. Slowly she moved her hand and touched my dick, I was in heaven and asked her how was. I was just about to give up and I turned off my TV and closed my eyes when I heard my door open.I saw Lana's silhouette in the doorframe before she quickly closed the door. She came over to the bed and crawled in with me. I was naked, and she was wearing a pair of PJ pants and tank top. She climbed on top of me and we started to kiss. She straddled me and gently rubbed back and forth on my hard cock."Um, you started without me." Hard not to, thinking about you." I said honestly."Thanks", she. After all, this was just acting so I just placed my hand on top of it. Under my touch, he went from slightly hard to fully erect. I looked down and saw that it looked like a cucumber under the fabric. “Pete, return the favor! Before you say anything, it’s another fifty bucks, Amanda.” Pete reached up with the hand that was closest to me and began caressing my vagina over the briefs. I was really starting to feel uneasy about this. He wasn’t acting. He was really trying to arouse me. “Oh my god. I brought up the possibility of a threesome at my house and he was all for it. I wanted to make sure he was okay with doing double penetration on me. Being so close to another cock can be a mental problem for some guys. He told me he had done it before and loved it so he was good to go.“What would you think if I told Greg to suck you either after we had finished or to get you completely hard before we fucked?”“I think I would be okay with it since neither of us is gay. He would only be doing.
