N:Birth Control Has its Side Effects

Chris steadied himself as Rhian pulled him by his now slender arm deeper into the store. He felt his new breasts wobble as he walked, undelicately behind her.
"Wait Rhi! What do you mean I am 'up to a D-cup' now?"
Chris had to catch his breath a little as his girlfriend playfully hefted his breasts and kissed him on the neck agressively. "Oh, stop playing games Chris. You knew this might happen if I went on the pill. Your body is reacting to the changes in my body chemistry. I'm glad you're finally willing to talk about it though. I've been noticing the changes in your moods, and your figure for weeks now."
Chris blushed deeply as he felt his nipples (and nothing else) harden from his girlfriend's advances. She seemed so much more assertive and direct now as she stared down into his full cleavage.
Chris' mind raced, trying to keep up with what Rhian was telling him. He was never a great science student, and feeling her breasts pressed against his was distracting him horribly. The dazed expression on his face amused Rhian, so she kept explaining.
"Honey, we talked about this! I told you if you stopped wearing condoms I would get a year dose pill, and that your hormones might change when your body got the false message that mine was pregnant. Hello? Any of this ring a bell?"
Chris started to understand just as Rhian turned him around and deftly cupped his left breast and stroked his nipple with her thumb.
"Ohh, but I don't mind having to buy you new bras. You know I have a thing for guys with big boobs. Giggle I haven't had any side effects from the pill yet, and if it stays that way, I may get another twelve month pill when this one wears off in five months. Especially if it keeps you so shapely and sensitive."
