Serena
The strap-on had been sitting in the Romantix bag on the chair for four days.
Neither of them mentioned it. It simply existed in the room the way significant things sometimes exist — present, patient, waiting for the moment to find itself naturally rather than being forced.
Serena was aware of it the way you’re aware of a book you’ve been saving. The right moment hadn’t arrived yet. She would know it when it did.
It arrived on a Wednesday evening in late March.
Not dramatically. Not with ceremony. They had come home from the park — Gerald had been in particularly imperious form, reorganizing the entire duck hierarchy before their eyes with the focused efficiency of a middle manager who had finally gotten his moment — and eaten dinner and helped Margaret with the dishes and somewhere between drying the last bowl and climbing the stairs Serena had simply known.
Tonight.
She told Connie after they’d changed for bed. Simply and directly, the way she said most things now.
Connie looked at her for a moment. Then she nodded and went to the chair and retrieved the bag.
They sat on the bed together and unpacked everything with the particular unhurried attention of two people who understood that what was about to happen mattered and didn’t need to be rushed toward. Connie filled the reservoir with the realistic semen, working through the mechanism with the focused competence she brought to anything requiring assembly.
Connie smirked as she qualified, “I’ll have you know, I’m completely winging this. I saw, one of my last year’s roommates assembling one of these for an evening’s entertainment she was about to partake in.”
Serena watched and handed things when asked and felt the anticipation sitting in her chest like something warm and patient.
When Connie had the harness on and adjusted she sat back on her heels on the bed and looked at Serena. She flashed two quick eyebrow raises with a grin.
Serena looked back. “What? What’s going on in that devious mind of yours?”
“Please kneel on the floor for me, will you, Baby Girl?”
Serena slid off the bed and sat back on her heels in front of her wife, who was wearing an erect lifelike penis in her fisted hand.
Connie held it out with a completely straight face. “You’re going to need to introduce yourself first.”
Serena stared at it. “What do you mean?”
“I want you to meet my friend. His name is Peter.”
Serena looked up at Connie’s expression and the laugh arrived before she could stop it — the real kind, the helpless kind — and the last of the nerves went with it.
“You’re terrible”
“I’m practical,” Connie smirked. “Also it needs lubrication and this is how that happens. I’m told he doesn’t bite, but he will spit at you.” She said it with a cheese-eating grin.
Serena was still laughing. She shook her head and looked at her wife and thought — this is who I married. This exact person. And felt the love move through her like something with no bottom to it.
“Seriously, Sis,” Connie said, “if you want real, I’ll give you real. Any guy you’re in a relationship with will want this. It’s just part of the curriculum.”
“Give Pete a couple kisses first,” Connie cooed.
Serena got into it, planting butterfly kisses all over it, noisily licking it while they both laughed, finding her way into it with the same focused determination she brought to everything she decided to master. Connie watched with an expression that was simultaneously warm and quietly amused and Serena heard her mutter something under her breath that sounded like I don’t actually feel that but thank you.
“Gonna cum, Baby Girl. Just hold the head in your mouth.”
Connie grunted and gave her three good squirts. Serena flinched, then swallowed quickly. She pulled off gasping, sat back on her heels and wiped her mouth with the back of her hand.
“Boy,” she exclaimed. “Sucking cock is a lot of work. Harder than eating pussy and doesn’t taste near as good.”
“Well,” Connie snickered, “I’ve only eaten one pussy, but I agree with you one hundred percent.”
Which set them both off into a laughing fit.
When the laughter settled the room found its different quality.
Serena crawled up onto the bed and lay next to Connie. She looked at her wife with a very serious expression and her eyes filled with tears. She raised her head and kissed Connie deeply and whispered, “Thank you for loving me enough to do this for me.”
Connie kissed her temple. “Anything for my pretty little wife.”
She knew Serena was nowhere near ready to be penetrated, so she decided to make love to her first.
They restarted by making out. Serena was such a good kisser and her small soft lips were cashmere against Connie’s mouth. I can damn near cum just kissing her.
When they were both flushed and warm Connie nipped her sister’s chin and trailed her way straight down her upper chest to her sternum and over to her right breast. She suckled gently, rolling the small button nipple with her tongue. Then she pulled back slightly, caught it between her teeth and pulled.
Serena shuddered, thrusting her chest upward. “That’s it, Sis. Claim me.”
Connie slid over and wrapped her hand around Serena’s left breast and squeezed, forcing the nipple to stand fully. She bit it and pulled. Serena cried out “Oh God!” and came suddenly and completely.
While her sister recovered Connie moved down, peeled open her labia and latched onto her clitoris — hood and all — with her lips, chewing and rolling the small button inside its hood.
Serena started bucking immediately, thrusting her hips upward, crying out “Oh God! Oh God! Oh God!” Then she grunted once and locked rigid as she came. Connie put her hand flat on her sister’s belly and felt the muscles frozen beneath her palm until Serena dropped back to the bed.
