I lay my not yet exhausted body on my mother's slim body and I could feel my cock still inside her cunt. It didn't take long before my sister began to...violently thrust her whole body With mother's gentle coaching Sierra and I fucked each other in some of the positions I did with Mother as well as some spur of the moment ones. Mother also showed Sierra how to suck a cock and they both took turns sucking on mine. For the finale I lay on my back with my cock standing straight up and she straddled. Very verycautiously I nod... yes always seems to be the right answer here. Shegives a wide grin as she walks back round the desk to me.."Oh you are so cute!" she says leaning in and kissing my neck. "ReadyAngel?"I prepare to nod, but she pushes me in the back forcing me to bend over..then harder so my cheek is resting against the desk. I wave my armshelplessly trying to keep balance, then grunt as she puts her weight onback winding me and pressing my breasts against the desk..I feel her move,. They loved the idea.That weekend we went to the beach and looked for likely girls, we saw a couple walking together who didn't have boyfriends with them and decided they were our prey. They were tall, blonde, early 20s and big tits and great asses. We heard them talking about Gucci stuff so we moved closer to them and made believe we were also discussing how we could get rid of some Gucci, we made sure they overheard. At first they ignored us but after a while one of them, Michelle, came over. I didn't bother with a bra, although I rarely go bra less, with D cup tits like mine it's best to keep them supported, but today I felt the underwired cups were bound to get really sweaty and the straps would be cutting in to my shoulders. I ran a brush a brush through my hair and applied a little make-up.Having slipped on a pair of open-toed sandals, I grabbed some cheese biscuits, some fruit and a bottle of water from the fridge. I checked my self in the mirror by the front door, and I had to.
