*Gulp*
Rias gulped down the burst of semen before feeling hot and cold all over the body, "This..."
Aleron remembered how Yueha's innate physique was upgraded after she absorbed his semen, so he quickly spoke, "Don't worry, Rias. After I got Primordial Genome Whisperer, my body has fundamentally evolved and houses a new power source, so this is going to be helpful to you."
Rias was surprised and then smiled as she leaned forward before she lay beside Aleron, a head above him as her breasts lay beside his face while her right hand caressed his chest, "It's upgrading my bloodline. I feel a bit of pain, so can you help by making me feel good?"
Aleron opened his mouth and sucked her breast into his mouth before grinning, "like this?"
"Mhmm~"
*Slurrpp*
"Ahaha, that tickles."
…
After one minute, Rias fell asleep with her bloodline patterns appearing all over her body.
