I didn’t know what she meant by cum, but I wasn’t going to stop and ask now. My cock started to drool, which got the front of her panties wet. I...thought she would get mad, but it only seemed to get her more excited.“You’re close Bobby; you’re close. So am I. I am going to cum soon. Please hurry! Cum in my panties!”And I did. My cock started to pump my first load of jis. Oh what a feeling. A stream of warm, thick liquid shot out of my cock and filled the front of my pink, nylon. You see Ken’ – Heather was warming to her specialisation now….‘When highly sexed older women, are maybe lonely, lost a husband or lover, they still get the horny hots and have fantasies. I provide this discreet outlet for them to fulfil their fantasies and try new things…and above all, they are pampered, admired and serviced without any fear or humiliation’.Well, who was I to disagree and confirmed that I would start the following Wednesday morning. During the interim my imagination went into. While she was resting on I start my movement in her pussy with my dick in slow motion.Me : See darling still I want more and I’m not done for first round.SIL [Anna] :I know baby. I like it. Don’t stops do it.Me : Baby I want you ass now.SIL [Anna] :No baby. Not now until u done for first round just fuck my pussy.I start fuck her from behind when she lie down I feel more tightness this time as she kept her legs very close. I took my pace and I cont. like for another 10 min and I cum for third. "So what the fuck are you doing here?" I asked my sister, ignoring what the other girl had told me."You moron, I'm helping out with our fund raiser, now get the fuck out, already." She spat back, not being sorry in the least for her actions.The tall girl looked back and forth at us and asked, "Do you two know each other?" Yea." I replied, still pissed off to find my sister sucking cock at this thing. My head was pounding as I prepared to tell the world what just happened."She's my..." I started.
