Issei was out doing a contract job whilst everyone else was sitting around, "Harvey, could you explain why you don't talk greatly?" Harvey shrugged, "I talk with my sword," he gave here a hearty smile as he gripped tighter to Io with their hug, Rias then received something through telepathy, "there's been a reported stray devil in an abandoned factory, Issei, please head there now," she spoke, then looking up at Harvey and Io, "I think it would be ok if you two stayed back, I doubt you've had any alone time together." "That would be appreciated, thank you," Io smiled lightly as the rest got up and headed out in a transportation circle.

Harvey immediately moved his hands away from Io's stomach and begins to grope her large breasts, Io softly moaned with a shortness of breath, biting the tip of her thumb as her creamy white face turned red. Her mounts were soft and plump, her skin as smooth as velvet; he pinched her nipples, "-ahn~!" the reaction was cute as Harvey also began to kiss her neck. He pulled away her straps and pulled her ragged gown below her breasts, letting them flop out, her areola and nipples were bright pink compared to her pale skin; a perfect contrast.

Harvey began to knead her breasts like dough, occasionally pulling her nipples, "nngh~~" Io clenched her toes and brought her knees together. Harvey brought a hand down to her crotch, a clean-shaven pussy lay waiting, drenched from the breast-play stimulation, her moans became more pronounced as he pinched and rubbed her clit using her juices as lubrication and stimulant, nibbling on her earlobe as he does so.

He quickly inserted two fingers into her pussy, causing her to buckle and orgasm, shooting her crotch up into the air and squirting onto Issei's bedroom floor, "Ahhhh~~!" she dropped down, panting, before Harvey brought his face over hers and locking lips, and beginning his exploration of her mouth with his tongue, using his fingers to claw at her prostate, causing immense satisfaction and several, unending orgasms.

He removed her gown completely from her body and took his own clothes off, allowing his 8 inch semi-hard cock to come out from being restrained under his boxer. Io, without command lowered herself on Issei's bed and began to service Harvey without trouble, she fondled his balls with one hand and used the other to hold his unruly Excalibur in place as her erotic tongue scaled the shaft, making it glisten in the open moonlight, her Golden eyes glowed red as she took all of it down her mouth and into her throat, his cock head was squeezed by her oesophagus and the bottom half of the shaft was assisted by the tongue, Harvey grunted like an unruly bear as he twitched.

Io began moving up and down, the whole cock was lubricated with her sticky saliva glistening more from the moonlight, Harvey grabbed the sides of her head as she dogged him down, her right hand working at her pussy, however she couldn't keep long before her mouth and throat were squirted with thick, creamy cum, her own body replying with an orgasm and squirting all over the bottom of Issei's bed. Pulling off after sucking every last bit off him, she swallowed his cum with a shiver of delight for servicing him, but also for the bland taste it had because of a Revenant's taste buds.

She mounted onto his crotch, her wet pussy grinding against his meat, her labia encasing it like a hotdog and bun, she leaned down and kissed him before pushing the shaft into her, a resounding plap of the skin echoed within the room as well as a heartfelt moan of outright pleasure, "Ahhhnnnnghh!!~~" Io's tongue hung from her mouth, she had done this 3 times before with Harvey but this felt much different to before. She began to slowly bounce up and down, the pleasure of her tight walls were almost unbearably pleasuring as Harvey grabbed her waist ad counter-thrusted into her, doubling the pleasure of both parties.

Io switched positions, she turned around so that her ass was shown towards Harvey and so that he could service it, which he did as both hands were firmly planted and firmly squeezing it as she worked harder on his cock, her moans couldn't be held in either, "Ahn~! Ahn~! Ahn~! Ahn~!" Harvey twitched again before pulling her down onto him, her back lying against his chest and abs, as he wrapped an arm around her neck and another around her stomach as his cock began to jackhammer her until they were both numb there before finally slamming into her and releasing inside. At that moment, the light turned on, Io squirted and Harvey's rock hard shaft pulled out, standing at the open doorway was an agape-mouthed, heavily Blushing Rias, The Peerage had returned to their homes and Rias came up to Issei's room to see the two lovers finishing a lovely round of sex, "Uh- Uhh..." Rias could barely find the words to speak as Harvey looked up over Io's shoulder as she panted heavily from both cumming and being cummed in.

"Hello Rias." He smiled as he panted, luckily Issei was still downstairs doing something, "Wha- What were you doing?" she was so red, her face almost matched her hair, "doing what lovers do," He smiled as she stared at his cock and Io's oozing pussy, "I- I can't even sleep there tonight." she looked down, as Harvey rolled Io off and sat up on the edge of the bed, his cock still twitching, he pats beside her, motioning for her too sit next to him, she reluctantly does so with a hint of curiosity, "W- what do you want," you're being very flustered for someone as cool-headed as you are," "I- I had just seen you two finish doing it together," "That's not very bad, I've had friends in my world walk in on me doing it with Io several times in Vein."

Rias continues to stare at his cock, it was massive, considerably larger than even Issei's, but Harvey was well-built and from another Dimension so it was to be expected but not in this way. "It's not normal here though, it's embarrassing for both parties normally." "We're not normal though, Io and I are Revenants, relationship between several people and walking o=in on others is somewhat normal, You devils also have polygamy, so there's not much to worry about.

The night drew longer and longer, Io had long fallen fast asleep and Harvey and Rias spoke continuously, it was going to be hard for her to even look at Harvey after tonight.
