Gina looked at her best friend and realized that it had to be true. Britney had to of blown Ed. Gina was turned on by thought of the two having sex an... the she thought of her petite friend being fucked by her sexy brother. She started to smile and Britney just looked at her with that questioning look."Can I ask you something really personal?" Gina asked"You know we are BFF's! You can ask me anything!" Britney replied"Do you enjoy sucking cock?" Gina asked"Yes! I like giving head." Britney. I begged him to stop a second but he didn't and he just shoved it in. After the head passed, it got a little better but not much so Sam held me down while Mike fucked me. I felt him cum inside of me and I started getting really slippry and it was easing up a lot by now. Sam then took his turn and fucked me even harder but instead of cumming in my ass, he pulled out, spun me over and stuck it in my mouth! I could taste my own ass juices mixed with Mikes cum but when Sam came, it was overwelming. When I removed her bra I began to caress her breasts then began to kiss them using my tongue to tease her nipples. She began to moan and clutched my head to her breasts as if she never wanted me to leave them.I undid her pants and as I slid them down I eased her back on the the couch so that her ass and pussy were haning on the edge. I kissed up the inner thigh of right leg pausing just long enough to tease her pussy by licking the outer part of her pussy lips. Then began to kiss up the inner. Finally Dad and Grandmother Margret went home. Both families spent a lot of time together after that. It was no secret that both our grandmothers enjoyed sex and especially oral sex. Grandmother Kate taught Dad the art of giving head using cucumbers and bananas. She and the other women would push it a little ways into their pussy then he would practice until he had learn to deep throat. Most of the time at night our grand mothers would sleep together and Dad would sleep with the girls. .
