Yes, they are! They scissor while blowing him!

"...sure, I could do with trying out this body some more... I thought this all would be a little demeaning, but it's so worth it..." Eiko flushed. "As long as I'm only a **** when it's for sexual purposes, then this is fun."

"Great, then let's scissor, and suck Master off! If you're fine with that position, of course," she added to Denki, who smiled and nodded.

"What's scissoring?" Eiko asked, and Mina giggled.

"Here, sit," she told her, and sat herself. When Eiko obliged, Mina scooted over to her, bringing their pussies in close proximity to each other. She put one leg over one of Eiko's, and slid her other leg under Eiko's other leg. "See, like this. It's called scissoring, because of the position of our legs," she explained as Denki stood at their sides. "Now we just rub our nether regions against each other!"

"Oh, I get it!" Eiko nodded, scooting the rest of the way, making their labias touch. Like their nether lips were kissing. Mina nodded and started grinding her hips against Eiko's, making her moan and try to imitate the motions. Mina then turned her head to see Denki's erection, and started to lick it.

Eiko noticed, and followed suit, licking from the other side. "Unh..."

"See, that's it, you're learning!" Mina cheered, before licking at Denki's scrotum, letting Eiko try taking Denki's cock into her mouth. Denki was briefly worried that her sharp teeth might be an issue, but she seemed able to handle his length without accidentally biting him. No doubt another blank Momo filled in for him.

Eiko experimentally bobbed her head, sucking hard. She couldn't believe how enjoyable she found the activity. Mina bucked her hips against hers, before pulling her off of Denki's cock so she could have a turn, engulfing it in her mouth. Eiko pouted briefly, before licking at his scrotum as she continued to grind her pelvis against Mina's.

Every minute or so, they swapped again, and Denki pet their heads. "Mmm, this is such a hot sight," Momo crooned, playing with her boobs as she, Kyoka and Akemi watched.

Denki moaned in agreement as Eiko sucked voraciously, her eyes shut, bobbing her head back and forth, taking him to the root each time without issue. He could feel his climax coming, and tensed up.
