‘I don’t think that’s pathetic,’ Brian commented gently. Samantha snorted a laugh, ‘It’s completely pathetic. You know how girls never wan...t to date nerdy guys into comic books?’ ‘All too well,’ Brian said. ‘You pretty much described my entire high school experience.’ ‘I’ve always been the pasty, four-eyed female version of that. Guys really aren’t interested.’ ‘I was interested,’ Brian reminded her. ‘Was,’ Samantha reached for some toilet paper. ‘Past tense. But I don’t blame you for choosing. Uhm, could you check on her? I know she likes you and ... I kind of miss Joanne. A little less unnerving bossing around.”They chuckled.“Sure,” he said. “But I’m not sure Joanne’s pussy’s ready for fucking.

I can’t imagine it not being safe. And ... I thought it would be like coming down. Like the hair of the dog or. If she had been thinking more clearly, she could have simple ripped the flimsy plastic open, but apparently she sees my hands holding the bag as the source of her problem, so that’s where she goes.I snap at her to cut it out, then tell her soothingly that she is safe. The combination seems to work, she calms down immediately and resumes pinching her nips. Just without air.After a few seconds I relax my grip and let in air under the bag, which my sister greedily breathes in. Two deep breaths,. Instead of stopping and pinching the base of my cock again, she whispered in my ear, "Go ahead. Breed me."I could feel her cunt muscles flexing deep inside her, deliberately coaxing me to cum."You are on birth control, right?"She coyly smiled as she ground her clit against my hand."Maybe... maybe not! There's only one way to find out."Her fingernails dug into my pecs.That was all I needed. I thrust deep, our pubic bones mashing together as my cock began to pump my seed into the depths of her.
