Once your roommates panties were removed, you found her penis sitting stiff, as she has already gotten herself a boner with how long she might be thinking of stuff she would plan to screw. Just then, Teresa's eyes opened, while you continued to suck on her shemale penis, and it caused her to wake up a bit.
Teresa found you hiding under the blanket, while sucking on her penis, so she removed it from her bed to find you sucking on her erect rod while she was sleeping. "Jimmy, if you wanted to have sex with me you should have asked," Teresa says. You didn't say anything else, as you continued to suck on Teresa's penis, which even caused her to moan a bit while you were doing it. You didn't normally have to suck on anyone's penis, but due to the trance you were under you couldn't stop.
