Brother's Girlfriend

A few years back I was sharing a house with my twin brother. His girlfriend spent a lot of time at the house, now she is a very cute petite blonde, barely five feet tall, all of a hundred pounds, beautiful perky ski sloped breasts with dark nipples. I'm fairly tall 6'1" brown hair and eyes, shaved down below.

Anyway one hot summer afternoon my brother was out working and I was home as well as his girlfriend. I was in between girlfriends and feeling horny with the summer heat, having fooled around with my brother and his girlfriend in the past (a story that might not be appropriate) and the fact that she was wearing next to nothing I got brave and started watching porn in the living room out in the open for her to see. Not only was I watching porn I also had a raging hard-on that I was fondling.

My plan worked and she walked in to me with a devilish grin. I asked if she wants to play. She was eager and wanted to help me, but I stopped her from touching me. I said we can't touch each other out of respect for my brother. She was happy with the rules and went down the hall to grab a little pink vibrator and towel. I grabbed a hand towel to blow my load in and some olive oil for lube.

Back on the couch with porn playing on the laptop I am now lubing myself up knowing that I can cum any stroke if I'm not careful, I pace myself and watch as my brother's girlfriend sits on the love seat across from me with her pink vibe and presses it against her shaved pussy. Grabbing her breasts with her other hand. I want to touch her but I made the rules so, and to make it worst I know how good she gives head. The no touching rules a hard not to brake, but make it even hotter. I asked her how close she was, because I can cum any time being a guy and want to know how long to edge for. Surprising she told me she can cum as quick as she wants to.

So at this point it was all as long as I wanted to edge for. Not knowing exactly how long my brother was gonna be gone I decided to not take too long. Now I am stroking slowly and cupping my balls as she is sitting legs spread on the couch with the tip of her vibe focusing on her clit. Ready to cum, but wanting to make it more exciting I suggest moving to the back porch out in the sun. The porch is private enough but if someone stops by we are caught with our clothing inside. The sun felt great as I masturbated and made her little wet pussy glisten in the sun. Now out in the open and ready to cum I move to the edge of the porch and explode several big squirts over the railing onto the bushes as she watches. She had already come so we sit down in the sun momentarily before gathering ourselves and clean up like nothing ever happened.
