Later on in the week Jay has a court date, I accompany y him and his mom whom got riled up with Nina over borrowing the car, she screamed at her "I'll... show you who has balls" as I tried calming her down. We get in the car and head out, the pk lots to the building is underground, idk how, but at some point the tip of my finger end up touching Isabel's ass as Jay's right next to her, she turns and looks at me then keeps walking. When were in the building I see her sitting at a bench on the phone. I'd never done this before but I suppose there is a natural ability in every girl to be able to sexually please a guy.I would look up at him at times and he sure looked happy. So did my sister who was sitting on the edge of her bed fingering herself. Now, I'd seen her naked before but not really for long, just fleeting glimpses. She had her legs splayed out and was running two fingers in and out of her bare, clean-shaven pussy."Oh, yeah, here it comes. UUH, UUH, UUH, UUH, uuh, uuh, uuh, ew, ew,. 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 painful 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. After massaging I lie back in the tub with you against me, resting. Thinking that after all that work you have to repay in turn, your hand snakes to my crotch and plays with my cock as I moan softly, my hands in your hair and on your neck. You use your excellent oral skills you have practiced on me many many times to make my cock hard as you use your hands on my thighs and stomach, your tongue licking my shaft and then gently biting it. I moan louder as you swallow all of my cum. I switch.
