"Ah..., I ah," I said, trailing off, not really having any good answer to give Shelia to explain the pictures and messages on my phone from Tiffany.
"I get it," Shelia interjected, "She's gorgeous. Ever since we were kids, all the guys always wanted to fuck her. Does mom know about this??"
"No, she doesn't," I replied, "and it's not a thing, it only happened once and it won't ever happen again. I love your mother very much, you girls are my step daughters, and it's totally inappropriate."
I waited nervously, hoping Shelia would buy that line of bullshit, as she continued to fiddle with my phone before sliding it across the table to me. She stared at me, almost quizzically, waiting to see if I'd offer more details or try further worming, backpedaling my way out of this shit I was neck deep in.
"So...," she said, breaking the deafening silence, "When does mom get home??"
"I don't know," I replied, "I know she has a big presentation at work next week and she's been putting in a lot of hours to meet her deadline."
"Ok," she said, getting up from the table and giving me a hug, "I think I'll come back by later this evening and see if she's home. See you later Michael."
"Have a good day sweetie," I replied, a little relieved to be out of that situation, at least temporarily.
****************************************************************************
I pulled back up to the house after a long day, tired and ready to unwind. My wife, Sally, had texted me earlier to let me know she would be late again, having to stay at work to finish some things up. I didn't see Tiffany's car, no telling where she was; however, Shelia's car was there, parked in the driveway. I walked into the house and saw her out lounging by the pool, drinking a beer.
I swear, if you didn't know better, you'd never guess Shelia and Tiffany were sisters, the two of them being almost complete opposites in every way. Tiffany was tall and skinny, with a darker completion, and a very outgoing personality. I hate to use the term "busy body", but that was a pretty apt adjective to describe her, she could definitely be a pain in the ass.
Shelia, on the other hand, was short, with a more athletic, curvy build (very similar to her mother). She had very fair skin, long, brunette hair, and pretty green eyes. She was the younger of the two by a few years, and was very shy, not one to be out and about like her sister. She saw me come in and waved at me, motioning at me to come out by the pool with her.
"What's up Michael," she asked, covering her eyes from the sun so she could see me, "Long day at work??"
"Always," I replied, "It never seems to stop. What are you up to??"
"Nothing," she said, "Just hanging out, relaxing with a beer, waiting for mom. Any idea when she will be home??"
"Not for a while," I replied, "She had to stay late again, she didn't get home last night till almost eleven o'clock."
"Well," she said, "Why don't you go change and have a beer with me?? I had these at my apartment from last weekend, figured I'd better not let them go to waste."
"Ah..., sure," I replied, "Let me go change."
Here we go again, I thought to myself as I walked back into the house, that walking on eggshells feeling. I figured I'd better humor her for a while, at least until I was convinced that she wouldn't tell Sally about Tiffany and I. I walked upstairs to change, stopping at the bedroom window to peek out at Shelia as I passed.
She was standing in front of the lounge chair, taking off her shoes. I watched as she lifted her T-shirt up over her head, revealing a skimpy, black bikini top, that was straining mightily to contain her massive breasts. Next, she wiggled out of her cutoff jean shorts, sliding them down past her hips, exposing her plump little ass. I had never seen Shelia in a bikini before, she typically preferred to be a little more conservative while hanging out by the pool; however, I must admit, this was a welcome sight. She lay back down on the lounger, giving me a good look at her body, as I stared out the window. Her tits were huge, at least a D, and very full. Even though she wasn't as skinny as Tiffany, she wasn't fat by any means, with a flat stomach, sexy full hips, and a nice ass. Damn, she looked just like her mother, I thought, instinctively rubbing my cock through my pants as it started to harden. I headed into the bathroom, changed into my swimsuit, and walked back downstairs.
"Well, there you are," she said, playfully, "I was starting to wonder if you were going to stand me up."
"No chance," I said, sitting down in the chair beside her, "I'd never pass up a free drink."
"Ha ha, asshole," she replied, tossing a beer my way.
"Just kidding," I said, "So, what's new in your life??" I asked, making small talk, trying to behave as normally as possible even though I was definitely scoping her out, sneaking peeks down her top as much as I could without being obvious.
"Not too much, just work and school," she said, "You know, normal bullshit."
"Gotcha," I replied, taking a sip of my beer, "Any new love interests??"
"I don't have time for that crap," she said, almost agitated, "Besides, guys are such assholes, present company excluded."
"I appreciate that," I said, "But you never know unless you get out and meet some new people, you might be missing out."
"I guess," she said, "Maybe one day I'll find the right guy."
We chit chatted for a while, just general bullshit, drinking our beers. Shelia and I had always had a pretty good relationship, we had a lot of the same interests, so we never had problems just hanging out. I have to admit, I was definitely enjoying ogling her in her bikini, I had never seen her like this before.
"Shit," she said, agitated, "Michael, can you rub some of this lotion on my back?? I can already feel my skin burning."
"Sure," I replied, reluctantly, as she passed me the bottle, turning over face down in her chair. I sat down on the lounger beside her and squirted some lotion on my hands, rubbing them together before I started applying it to her back and shoulders. Her tits were mashed against the chair, spilling out the sides of her bikini, the tiny straps struggling mightily to hold her in.
"Mmmmmm, that feels nice," she said, as I worked the lotion into her skin, "Are you enjoying this daddy?? Do you like sneaking peeks at me in my bikini?? Am I making you hard??"
Oh fuck, I thought, what the fuck was that?? I didn't know what to do. Suddenly, she leaned her head back and looked at me, a mischievous smile on her face.
"I read the texts Tiffany sent you," she said, "Did you jerk off for her?? Did you enjoy her watching you??"
I didn't know how to respond. On one hand, if she read the texts, I'm sure she knew the answer to both of those questions was yes; however, I couldn't say yes, could I?? Should I say yes?? Did she want me to say yes?? I was thoroughly confused at this point.
"It's Ok if you did daddy," she said, obviously sensing my discomfort but still pushing this forward, "But you better do it for me too. I want to see."
Without warning, Shelia turned over so that she was lying on her back. She reached behind her back and untied her bikini top, letting it fall to the ground beside her lounge chair, exposing her massive tits.
"Do you like them daddy??" she asked, pressing them together in her hands, "There much bigger than Tiffany's, aren't they??"
Yes, they were, and they were magnificent. They were at least a double D, very full, with large, dark nipples that were hard enough to cut glass. My cock was instantly hard in my pants, straining against the front of my swimsuit, begging to get out.
"Do you want to suck on them daddy??, she asked, innocently, "Look how hard my nipples are."
I leaned forward and took Shelia's hard nipple into my mouth, rolling my tongue over it, before sucking at her tit like a new born baby. I took her other nipple in my hand, rolling it in my fingers, further arousing her.
"I can see you're hard daddy," she cooed, "Jerk off for me. Don't you want to cum for your little girl??"
I was too far gone at this point to even consider the consequences of my actions, Shelia's nipple in my mouth, her other tit in my hand, my cock, rigid as steel. I stood and untied my swimsuit, sliding it down and exposing my cock to my stepdaughter.
