Having not been laid all day, and with Alexa and our friends teasing me quite often during the day, I wasn’t surprised I was ready to cum rather quickly. I was polite enough to warn Stephanie I was already close, Cindy urging her sister on, almost demanding that she swallow my cum, though also asked she share some of it with her.
Stephanie moaned softly when she felt that first spurt of cum erupt from my cock, her gorgeous eyes lighting up with delight. She gulped down a couple before I assumed keeping the rest. As soon as my cock stopped throbbing, she released it and turned to kiss Cindy, both moaning softly as they shared the rest of my load.
“Totally fucking hot,” I muttered. Both turned to look at me and smiled before gulping down whatever was in their mouth. Helping both to their feet, I kissed my fiancee first, running my hands down her body to her arse, loving the giggle as her girlcock pressed into me. Turning to her sister, she practically melted against me, enjoying just being in my arms.
Ending up on the bed together, Stephanie on her back, Cindy on her side, I spread Stephanie’s legs to be greeted by a well-groomed pussy that glistened from her obvious excitement. Cindy kissed her sister again, a sign that I really should just focus between her legs and she’d take care of matters elsewhere. Her scent was intoxicating. I’d always loved Megan’s scent, and since we’d started having fun again, I’d realised how much I had genuinely missed it at times.
I teased her to start with, but once I figured out what she seemed to like, I soon had Stephanie moaning, spreading her legs wider so she was completely exposed to me. As I ate her out, Cindy was still kissing her, hearing the very sweet words they were exchanging at the same time. Both knew what they were doing, what this meant, and I knew that their relationship had likely changed because of it.
Stephanie enjoyed more than one orgasm while I was going down on her. I complimented her constantly on her taste, how beautiful she was, and also how great her pussy was. Cindy eventually kissed down her body and joined me between her legs, just having a look at her sister. “Well, she’s seen my girlcock a few times so I should get a good look at her pussy in return,” she stated.
“Do you like my pussy, Cindy?” her sister asked.
“It’s as beautiful as the rest of you, Steph. Are you ready to make love to my sister, Mark?”
“Definitely, if she’s ready.”
“I am,” Stephanie said softly.
She moaned as I slid my cock inside her. She was hot, tight and wet, definitely ready to be fucked. Cindy lay beside her again, watching me slowly thrust into her sister. Stephanie couldn’t stop smiling, leaning down to kiss her, turning to kiss her sister from time to time. I was glad I’d already been blown, otherwise I’d have cum rather quickly.
Spinning her over onto her knees, her head almost buried into the pillows, I grabbed her hips and started to really pump into her. I knew I was going to last too much longer, not embarrassed that fucking Cindy’s sister was turning me on. We knew she was still on the pill, but one day, we’d be doing this and there was a good chance she’d eventually be pregnant, ready to give Cindy and I a child.
Warning her I was close, Stephanie turned back and smiled, begging me to cum inside her. Cindy sat on her knees next to me, cheering me on, urging me to fuck and fill her sister right up with my cum. I kissed her while I kept pumping Stephanie, and I groaned as I did finally cum. Leaving my cock buried once I was empty, I pulled Stephanie back to rest against my chest. Cindy moved so she was sandwiched between us.
“You’re so beautiful,” Stephanie told her sister, “I really want to be naughty with you right now.”
“Me too,” Cindy admitted, “But it’s a step too far, Steph. Kissing is one thing, being naked is another. Sex is a whole other thing.”
We shared a group hug, kissing both women in my arms. “If you ever wanted to, you have my support,” I told them both, “I can see and feel how close you are.”
“I love my little sister so much,” Stephanie whispered, “The bravest woman I know. She’s always had my love and respect.” Pausing, she turned so she could meet my eyes. “I’d love to see you make love to my little sister, Mark.”
“I’ll ride him so you can really see me, Steph.”
Lying on my back, Cindy sucked my cock first, grinning before mentioning she could taste her sister on my cock. Stephanie giggled and blushed, admitting just the idea was a little kinky. Getting me nice and hard, as it had been quite the orgasm, Cindy got herself ready with some lube before carefully sliding down my cock. Cindy was rock hard herself, lubing up her girlcock, slowly riding me as she stroked herself.
“So beautiful,” Stephanie stated, cuddling into my side, “Part of me would love to suck you off right now, Cindy, but I think it’s because I’m still rather horny and watching you right now is erotic.”
“When we start to think about a family, I think we get kinky,” Cindy said, giggling to herself, “What do you think, Mark?”
“I think we take care of your sister from both ends.”
Stephanie kissed my cheek. “Totally hot,” she whispered.
Cindy was soon riding me quickly, her hand almost a blur as she stroked herself. Leaning forward to rest on her other hand, I knew she was getting close to orgasm. Leaning up to kiss her, she smiled at me, her eyes full of all the feeling she was experiencing in that moment. My hands were caressing her back, the sensation of her soft skin, running down to her perfect little arse. Her sister had been fun to be with, but I loved Cindy, and the sex with her was always fantastic.
Warning me she was about to cum, I waited until she started to spurt all over me, moaning lightly to herself. I felt her sister cuddle into me tighter. “I used to love watching my little sister cum,” she said, “But watching her cum like this is just beautiful.”
“I love making her cum,” I added, “Knowing she’s enjoyed me so much…”
Cindy leaned down to kiss me, before turning to kiss her sister. “Fuck me, Mark,” she asked.
Grabbing her arse, I was soon pounding her little arse for all I was worth. Resting her head against my shoulder, she just begged me to keep going until I filled her up. When I did finally cum, the groan I released had both women giggling as it was another fantastic orgasm. Cindy pushed down on my cock as I came, ensuring it all was left inside her.
Eventually sliding off my lap, we all needed a shower after that. Checking my sister was still fast asleep first, we had a lot of fun in the cubicle, my hands all over both women, the sister’s continuing to make out again. I could see Stephanie really wanted to touch her sister intimately, but held herself back. That was perhaps pushing it too far in both their minds.
Back in bed, Cindy snuggled back against me as always, Stephanie back against her sister. Being naked, Stephanie was giggling as Cindy was poking her in the back. “Can’t help it,” Cindy whispered, “My big sister is a hottie.”
“It feels nice against me,” Stephanie whispered back, “Part of me has always wondered how it would feel… You being inside me, Cindy. My little sister…”
Cindy giggled as my mind filled with the vision of Cindy and Stephanie making love, and I was definitely poking her as well. We’re all told that such things should never happen, but considering they were beautiful women, I just couldn’t help thinking about it.
“I think Mark likes that idea, Steph.”
“I don’t blame him. The idea of two sisters going at it, particularly with your pretty girlcock…”
“You want to make love with Mark again?”
“In the morning. I’m tired now.”
It had been a long day so the three of us did eventually drift off. Waking the next morning, Cindy had turned around to snuggle into me, her sister also turning and cuddling her sister from behind. Cindy was already awake, having waited for me to wake up. Kissing my cheek, she whispered that she’d go start on breakfast.
Moving out of the way, I moved closer to Stephanie, rolling onto my back as she snuggled into my side. Hearing a knock at the door, I turned to see Jane standing in the doorway in just her underwear. I’d seen her in a bikini more than once during the summer, but there was something a little more erotic about the underwear she was wearing.
Lifting the sheet, she giggled and immediately slid under to join me. Snuggling into my other side, she asked, “Are you naked?”
“Yeah.”
“Oh… Did you and Stephanie have sex last night?”
“We did. You know about our agreement?”
“I do, I just didn’t… Well…” She kissed my cheek. “You really are living your best life. Where’s Cindy?”
“Making breakfast for us. Stephanie wanted a cuddle and might want to make love again.”
Jane cuddled into me tighter. “Thanks for looking after me last night. I felt like a mess.”
“You were fine considering the circumstances, Jane.”
“I didn’t weird you out with what I admitted?”
“No, I think such things are somewhat normal when you’re younger. Still have a crush on me though?”
“I just think my older brother is a handsome, good-natured and kind man.”
“I’m a little jealous,” Stephanie admitted, “But I’ve never seen my sister so happy. That’s why I’m so willing to help them out by them a child.”
Cindy’s head popped through the doorway, noticing Jane was also in bed with me. To Jane’s slight surprise, she stripped off and slid in next to Jane, my sister giggling when Cindy cuddled into her. “Are you turned on, Cindy?” she had to ask.
“You haven’t seen my girlcock before, have you?”
“No,” Jane whispered.
Cindy threw the sheet back to reveal her naked body. Watching Jane’s eyes, they widened as Cindy gave her girlcock a few caresses. “Many girls like me don’t like theirs,” she explained, “But I think I have a very pretty girlcock, and Mark loves it too.”
