I used my fingers to give her pleasure in return.In the morning I asked Clara why she didn’t have intercourse anymore. She said it had become painfu...l and her doctor wasn’t any help. I’d noticed that I couldn’t stick my tongue very far into her vagina. I had an idea I wanted to try later.Courtney had obviously had a good time too and winked at me. We didn’t have much of a chance to talk privately but I did tell her that Clara would suck Dad off at least once a week and he had gotten some Cialis. She was very proud of her 40" breasts and her nipples were soon beginning to strain through the material. I undid her blouse to get more up close and personal with those fine orbs. I tweaked her nipples and she began to moan. My cock was starting to swell and Angela was rubbing the front of my trousers. I pulled her bra up to expose her magnificent tits and started to suck her nipples. They were very hard and as I sucked her tits I began to pull her skirt up. She wasn't wearing tights, she was. The pain was there but the pleasure was overwhelming. Slowly, she inserted her whole dong, inside my tight butt. Now it was my time to moan.At first, she was doing at a slow pace, and then gradually it increased. While she was pounding me, her one hand was stroking my cock, while with the other she was slapping my ass. I was now my sister’s bitch. After 20 mins of intense fucking of my ass, she came in my ass and then kneeled down to give me an amazing handsfree blowjob. I spilled all my cum. Apparently she asked to see Melissa DiMartino,” with that he stepped sideways and I saw Melissa was standing behind him.Melissa was in my class and was the sister of Laura who Tara hung around with. You know, Laura DiMartino, the queen of all bitches. Melissa wasn’t nearly as bad as her sister. She kept pretty much to herself but she often spoke up in class and had good ideas and asked sensible questions so I figured she was pretty smart. She mostly left me alone too. I mean she laughed with.
