Lilac's eyes lit up as Silvia's breasts began to swell up, firming and, from the looks of her reactions, growing more sensitive. She lowered her mouth to the breast that had been neglected for some time now, tongue flicking over the hardened nipple and rolling around it before pulling the nipple into her mouth to suck on it. The tendril at her sex took this time to harden its outer skin, becoming far more rigid and hard, but sacrificing flexibility. She teased her entrance with the hardened tentacle once more before sliding it teasingly slowly into her. The tendrils of the other hand continued to lather her opposite breast with attention, one wrapping around the nipple rather tightly and pulling upwards while the one wrapped around the entire breast gave a firm squeeze.

Unh... Silvia moaned as the gelatinous woman wrapped her lips around the firm peaks of her nipples, the flesh more sensitive then ever before as her breasts grew larger. As the tentacle toying with her sex slowly slipped its way into her body, a pleasured moan escaped her lips. Enjoying the many pleasures as her body was toyed with, her body pushed upward towards the woman as her hyper sensitive breasts were squeezed firmly and the effects of the drug becoming evident to her as a gush of milk burst from her altered breasts.

Lilac's suckling was rewarded with a stream of milk from her breasts and she happily continued to suckle on her breasts, membranes within her mouth allowing the liquid to cross into her body and begin to be broken down into usable components. Her tendril like hand formed into a suction cup of sorts and capped the other breast, doing the same on it so as not to waste such a precious resource. She rarely did this as the effects were quite noticeable to the other students, but she just couldn't let such a wonderful prize go to waste.

The hardened tendril at her sex pressed slowly but relentlessly into her until she felt it bump into Silvia's cervix. She gave the woman only seconds to get used to the intrusion before she began to thrust it in and out of her sex, gradually picking up speed. Small bumps formed on the surface of the hardened tendril, increasing the sensation that she would be feeling as it thrusted in and out of her, but its main purpose was to absorb her feminine juices that were becoming more and more available as time went on
