‘I can deal with that. I’ll trust you first.’ She leaned in again, only this time, instead of kissing him, she stuck her chest out, pressing her...large breasts right up to his face. Glancing down at her hardening nipples, he couldn’t help himself, and ducked his head down to take the left nipple in her mouth, as his hands gripped her hips. She let out a gasp as he did, and said, ‘Yeah…’ He then brought his right hand up to her other breast, and cupped it, then pinched its nipple between his. She said they had been working out and he mentioned that his wife and son had gone to Florida and he was all alone. She said that she noticed his semi hard cock in his shorts and she thought she would flirt with him . She said I spread my legs wide as I did my exercises giving him a clear view of my legs all the way up to my thong under my shorts. I started to pull down her little shorts and she told me if you pull those down you'll have to eat my pussy. I snatched them down quickly. Where are. I don’t think she appreciated the taste of her sister’s shit very much but her spit provided nice lubrication. I could tell from the sound of Sara’s moans that she was becoming more comfortable with the stretching of her ass. After about thirty minutes of butt fucking I was ready to cum again. I rammed my cock all the way into Sara’s ass and squirted a massive load; my forth climax of the day. I continued to pump in and out as my semen rushed into her butt. I could hear the splashing of my cum. As a result of this, a positive outcome, she became much freer when the two of us were having sex to say things, even ‘dirty’ things, which really turned her on. In any case, Frank did just what she demanded – he shot cum deep into her as they writhed and thrashed in orgasm, their pubic bones held firmly together as he jetted into her. Actually, as she commented later, she was usually in the midst of orgasm before he got there which worked out perfectly this time. He lay on her for a short.
